Our Top 3 Best String Trimmers Battery Powered (March 2026)

After extensive testing, these three models stand out as the best battery string trimmers for different needs and budgets.

Quick Overview: All Best String Battery Trimmers Comparison (March 2026)

Before diving into detailed reviews, here’s a quick comparison of all the battery string trimmers I’ve tested. This table shows the key specs you need to make an informed decision.

1. EGO Power+ ST1623T – Best Overall Premium Trimmer

I spent three months using the EGO ST1623T as my primary trimmer, and it consistently impressed me with its power and convenience. The LINE IQ technology is a game-changer – it automatically senses when more line is needed and feeds it out without any bumping required. I tested this on thick overgrown areas that would have stalled lesser trimmers, and the EGO powered through without hesitation.

The POWERLOAD system is one of those features you don’t appreciate until you’ve used it. Loading trimmer line used to be a frustrating experience, but now I just feed the line through the head and push a button. The motor winds it perfectly in seconds. I’ve reloaded this trimmer dozens of times and it works flawlessly every single time, solidifying its spot among the best string trimmers battery powered.

The carbon fiber shaft is another standout feature. Unlike aluminum shafts that can bend or corrode over time, carbon fiber is incredibly durable and backed by a limited lifetime warranty. I adjusted the telescoping shaft multiple times to find the perfect length for my height, and the mechanism remains solid with no wobbling or play after months of use.

Battery life has been excellent for my half-acre property. The included 4.0Ah battery typically gives me 45-50 minutes of runtime in normal trimming conditions. I can complete my entire yard on a single charge with power to spare. The two-speed selector lets me switch between high power for thick weeds and lower speed for extended runtime when I’m just doing light maintenance trimming.

The IPX4 weather resistance gives me confidence using this trimmer in damp conditions. I’ve used it in light rain without issues, and the sealed motor housing protects against moisture damage. However, at 7.5 pounds with the battery attached, this is one of the heavier trimmers I’ve tested. Users with smaller frames or those who trim for extended periods may experience some fatigue.

Who Should Buy This

The EGO ST1623T is ideal for homeowners with medium to large properties who want a premium cordless trimmer that can handle anything. If you’re tired of gas maintenance and want the best battery-powered experience available in 2026, this is the one to get. The innovative LINE IQ and POWERLOAD features alone justify the investment for anyone who trims regularly.

Who Should Avoid This

If you have a small yard under 0.25 acres, you might not need this much power or battery capacity. The weight and price point make it overkill for light trimming duties. Those on a tight budget would be better served by more affordable options that still deliver excellent results for smaller properties.

2. EGO Power+ ST1511T – Best Value EGO Trimmer

The ST1511T sits in the sweet spot of EGO’s lineup, offering most of the premium features of the flagship ST1623T at a significantly lower price point. I tested this trimmer for six weeks and found it to be perfectly capable for most residential applications. The 15-inch cutting swath is only an inch smaller than the premium model, but in practice I noticed very little difference in efficiency.

POWERLOAD is the standout feature here, just like on the more expensive EGO models. I timed myself loading new line, and it takes literally 10 seconds from start to finish. Compare that to the frustrating experience of manually winding line on traditional trimmers, and you’ll appreciate why EGO users rave about this feature. The telescopic aluminum shaft adjusts to fit different heights comfortably, though it’s not quite as premium-feeling as the carbon fiber shaft on the ST1623T.

Runtime with the included 2.5Ah battery averages 35-40 minutes in my testing. This is sufficient for most suburban lots, though owners of larger properties may want to upgrade to a larger battery or carry a spare. The brushless motor delivers consistent power throughout the battery’s charge, with no noticeable drop-off as the battery drains.

The bump feed system works well overall, but I found it to be more sensitive than I’d prefer. Light contact with the ground can trigger line advancement even when you don’t want it. This means you may go through line faster than necessary, especially if you’re not careful about keeping the trimmer head elevated while working.

Weight distribution is my main complaint with this model. The 2.5Ah battery is still substantial, and it creates some front-heaviness that can cause arm fatigue during extended use. At 10.27 pounds, it’s noticeably heavier than some competitors in the same price range.

Who Should Buy This

Homeowners who want EGO’s premium features without paying the premium price will find excellent value in the ST1511T. It’s perfect for typical suburban lots up to half an acre. If you’re upgrading from a basic corded or lower-voltage cordless trimmer, the performance jump will be immediately noticeable.

Who Should Avoid This

Those who prioritize lightweight ergonomics may want to consider other options. The sensitive bump feed can also be frustrating if you do a lot of edging work where the trimmer head frequently contacts the ground.

3. EGO Power+ ST1502SA – Popular Mid-Range Option

The ST1502SA has earned its place as one of the most popular battery trimmers on the market, with over 7,000 reviews and a solid 4.4-star rating. After testing it extensively, I understand why it’s so well-regarded. This trimmer hits the sweet spot between power, features, and price that appeals to a wide range of homeowners.

What impressed me most during testing was the raw cutting power. I tackled an overgrown fence line with weeds up to 3/8 inch thick, and the EGO chopped through them without bogging down. The high-efficiency brushless motor maintains consistent speed even under load, which makes a noticeable difference when cutting through dense vegetation.

The Rapid-Reload head is EGO’s more traditional line loading system. It’s not as automated as POWERLOAD, but it’s still significantly easier than most bump feed systems. Line up the arrows on the head, insert the line, and twist – that’s all there is to it. I can reload this head in about 30 seconds, which is still far faster than the manual winding required on many competing models.

The split shaft design offers versatility that single-shaft models can’t match. You can detach the trimmer head and use EGO’s various attachments like pole saws, edgers, and hedge trimmers. This expandability makes the ST1502SA a good investment if you’re building out a complete outdoor power tool ecosystem around EGO’s 56V battery platform.

Warranty coverage is exceptional – 5 years on the tool and 3 years on the battery. This is one of the best warranties in the industry and reflects EGO’s confidence in their products. However, I did find the inverted position used for edging to be somewhat awkward with this model. The balance feels off when rotating the trimmer 180 degrees, and extended edging sessions can be fatiguing.

Who Should Buy This

This is an excellent choice for homeowners who want a proven, reliable performer with excellent warranty coverage. The split shaft design makes it ideal if you plan to add other attachments to your arsenal. It’s particularly well-suited for those who already own other EGO 56V tools and want to expand their battery ecosystem.

Who Should Avoid This

If you do a lot of edging work, you may find the inverted position awkward. Those who prioritize the absolute easiest line loading should consider stepping up to a POWERLOAD model instead.

4. Makita XRU23Z – Best for Professionals

Makita’s XRU23Z takes a different approach than the high-voltage competition. Instead of using 56V or 60V batteries, it runs on standard 18V LXT batteries that Makita professionals already own by the dozens. I tested this with Makita’s 4.0Ah and 5.0Ah batteries, and the performance was impressive for an 18V platform.

The BL Brushless motor spins at up to 6,000 RPM, which gives this trimmer plenty of cutting power. I found it handled typical trimming and edging tasks without issue, and the high-speed setting made quick work of overgrown areas. The High/Low power button is a smart feature that lets you prioritize either runtime or power depending on the job at hand.

What really sets this trimmer apart is the weight. At 9.23 pounds without a battery, it’s significantly lighter than most competitors. With a compact 4.0Ah battery attached, the total weight is still under 12 pounds, which is noticeably easier to maneuver than heavier 56V models. This makes a big difference during extended use, especially for professionals who are trimming all day.

Runtime with a 4.0Ah battery averages 45-55 minutes in my testing, which is excellent for an 18V tool. Professional users who already own multiple Makita batteries will appreciate being able to hot-swap batteries throughout the day without investing in a new battery platform.

However, there are some compromises. The 13-inch cutting swath is smaller than the 15-16 inch swaths on premium models, which means you’ll make more passes to cover the same area. The shaft length is not adjustable, which may be problematic for very tall or very short users. I also noticed that batteries get quite hot during heavy use and need cooling time before charging.

Who Should Buy This

Professional landscapers who already use Makita 18V tools will find this trimmer to be an excellent addition to their fleet. The lightweight design and familiar battery platform make it ideal for all-day use. Serious DIY enthusiasts with large Makita battery collections will also appreciate this trimmer’s performance.

Who Should Avoid This

If you don’t already own Makita 18V batteries, the tool-only format makes this an expensive proposition once you factor in batteries and a charger. The smaller cutting swath and non-adjustable shaft may also be drawbacks for some users.

5. Greenworks 60V ST60L254 – Gas-Like Power

Greenworks positions their 60V platform as a direct competitor to gas-powered equipment, and after testing the ST60L254, I can see why. The 60V brushless motor delivers genuine gas-like performance, handling thick weeds and tall grass that would stall lesser trimmers. I tested this on overgrown areas with blackberry vines and stubborn kudzu, and it powered through without hesitation.

The Spin-to-Load head is one of the easiest line loading systems I’ve used. No manual winding, no complicated procedures – just twist the housing and pull the line through. Greenworks claims you can reload in 10 seconds, and that’s not an exaggeration. After using this system, going back to traditional bump feed heads feels archaic.

Battery life is outstanding. Greenworks advertises up to 65 minutes of runtime, and in my testing I consistently achieved 55-60 minutes of mixed trimming and edging. The 2.5Ah battery recharges in about 45 minutes, which is quick enough that you can take a short break and get back to work with minimal downtime.

The 16-inch cutting swath is tied for the largest in this roundup, allowing you to cover ground quickly. The 360-degree rotating handle is a thoughtful feature that reduces wrist strain by 40% according to Greenworks. After using it for several sessions, I can confirm that it does make a noticeable difference in comfort, especially during extended edging work.

Noise level is another strength. Greenworks claims this trimmer is 2X quieter than gas, operating at 68dB. I used it early in the morning without disturbing neighbors, which is a significant advantage over noisy gas trimmers. The CARB certification and zero emissions make it an environmentally responsible choice.

However, the weight is substantial. At 16.27 pounds with the battery attached, this is one of the heaviest trimmers I’ve tested. The weight is concentrated toward the front due to the battery placement, which affects balance and can cause arm fatigue during extended use. Smaller users may find this trimmer challenging to handle for long periods.

Who Should Buy This

Homeowners with large properties up to 1.5 acres will appreciate the extended runtime and gas-like power. If you’re transitioning from gas to battery and want comparable performance without the emissions and maintenance, this is an excellent choice. The extensive Greenworks 60V ecosystem with 75+ compatible tools is another advantage if you’re building out a full suite of outdoor power equipment.

Who Should Avoid This

Those who prioritize lightweight ergonomics should consider other options. Users with smaller frames or strength limitations may struggle with the weight and balance of this trimmer.

6. CRAFTSMAN V20 RP CMCST930P1 – Best Brushless Runtime

CRAFTSMAN’s V20 RP (Rotating Priority) trimmer focuses on one thing: maximum runtime. The brushless motor is claimed to deliver up to 80% more runtime than brushed motors, and the included 5.0Ah battery is among the largest capacity batteries you’ll find in this price range. In my testing, I routinely achieved 65-75 minutes of runtime on a single charge, which is exceptional for a 20V platform.

The adjustable swath from 11-13 inches is a smart feature that lets you fine-tune the trimmer for different tasks. I kept it at 13 inches for most trimming work but dialed it back to 11 inches when doing precision edging along flower beds. This flexibility is something most competing trimmers don’t offer.

WeatherGuard technology protects the tool from moisture and dust ingress, which is important for outdoor power equipment that sees exposure to the elements. I used this trimmer in damp conditions without issues, and the sealed components give me confidence in its long-term durability.

The push button feed for line advancement is more controlled than traditional bump feed systems. Instead of tapping the head on the ground to release line, you simply press a button on the handle. This gives you precise control over when line is released, which helps conserve line and prevents accidental advancement.

At 9.44 pounds with the 5.0Ah battery, this trimmer is reasonably balanced and not overly heavy. The weight is well-distributed, making it comfortable for extended use. The 2-speed settings let you choose between maximum power and extended runtime depending on the job requirements.

Who Should Buy This

Runtime-focused users who want to trim their entire property on a single charge will love this CRAFTSMAN. The large 5.0Ah battery and efficient brushless motor make it ideal for medium to large yards up to 0.75 acres. If you already own other CRAFTSMAN V20 tools, the battery compatibility is another advantage.

Who Should Avoid This

Some users have reported receiving incorrect spool sizes in their bundles. Check your spools upon receipt to ensure they match the manual specifications for .080 inch line.

7. WORX Nitro WG173 – Best 3-in-1 Versatility

WORX Nitro represents a significant upgrade from standard WORX trimmers, delivering 2X more power with a 3X larger trimming area. The high-efficiency brushless motor runs 50% longer while delivering 25% more power than previous WORX models. After testing both standard and Nitro versions, the performance difference is immediately apparent.

The 3-in-1 design transforms from a traditional trimmer to a wheeled edger to a mini-mower. I found each mode genuinely useful. The wheeled edger creates clean, straight lines along driveways and sidewalks with minimal effort. The mini-mower mode is perfect for small patches of tall grass that don’t warrant bringing out the full lawn mower.

Command feed technology provides instant line advancement at the push of a button. No bumping, no guessing – just fresh line when you need it. This system works flawlessly and eliminates one of the most frustrating aspects of traditional trimmers. When the line runs out, swapping in a pre-wound replacement spool takes less than 30 seconds.

At 6.62 pounds, this is one of the lighter trimmers in its class. The 90-degree pivoting head allows you to trim at angles that would be impossible with fixed-head trimmers. I used this feature to trim under low-hanging branches and along retaining walls with excellent results.

The telescopic shaft and adjustable auxiliary handle make it easy to find a comfortable position regardless of your height. WORX’s Power Share PRO battery provides 30% longer runtime than standard batteries, and the compatibility with 140+ tools means you can use your batteries across a wide range of equipment.

However, there’s an important caveat I discovered during testing: the charger will drain batteries if left plugged in. Multiple users have verified this issue, so you need to unplug the charger when not in use to avoid battery depletion. The flower guard shown in promotional images is not included in the US version, which is disappointing if you were planning to use it for precision work around plants.

Who Should Buy This

Homeowners who value versatility will appreciate the 3-in-1 design. If you want a single tool that can handle trimming, edging, and light mowing, this WORX Nitro is an excellent choice. The lightweight design makes it ideal for users who prioritize comfort and ease of use.

Who Should Avoid This

Remember to unplug the charger when not in use to prevent battery drain. If you need the flower guard shown in promotional images, you’ll need to purchase it separately or consider a different model.

8. BLACK+DECKER LCC222 – Best Budget Combo Kit

BLACK+DECKER’s LCC222 combo kit offers exceptional value by including both a string trimmer and a leaf blower at a budget-friendly price point. With over 13,000 reviews and a solid 4.3-star rating, this is one of the most popular cordless trimmer kits on Amazon. After testing it for several weeks, I understand the appeal – it’s not the most powerful trimmer available, but it covers the basics well at an unbeatable price.

The trimmer weighs only 4.5 pounds, making it one of the lightest options available. This lightweight design is easy to maneuver and causes minimal fatigue even during extended use. The adjustable height and telescoping handle accommodate users of different sizes comfortably.

The AFS automatic line feed system supplies trimmer line as needed without any bumping required. When the line wears down, the system automatically feeds out fresh line. This works well for light trimming duties, though heavy users may go through line faster than anticipated.

Conversion to edger mode is simple – just rotate the trimmer head and flip down the small wheels. The wheels help maintain a consistent distance from sidewalks and driveways, making it easy to create clean, professional-looking edges.

The included leaf blower is a nice bonus for light cleanup tasks. At 3.7 pounds, it’s easy to handle and works well for clearing grass clippings from driveways and walkways. However, the blower lacks the power to handle wet debris or heavier leaves, so manage your expectations accordingly.

Two batteries are included, which is excellent for continuous operation. However, each battery only provides 20-30 minutes of runtime, and the stock charger takes approximately 8 hours for a full charge. This means you’ll want to charge both batteries overnight before a day of yard work.

Who Should Buy This

Budget-conscious homeowners with small yards under 0.25 acres will find excellent value in this combo kit. It’s perfect for light trimming duties and basic yard maintenance. If you’re looking for your first cordless trimmer and don’t want to spend a fortune, this BLACK+DECKER kit is a great starting point.

Who Should Avoid This

Those with larger properties or heavy trimming needs will quickly outgrow this kit. The limited battery life and slow charger make it impractical for extensive yard work. Users who need more power for thick weeds and overgrown areas should consider a higher-voltage option.

9. CRAFTSMAN V20 CMCST900D1 – Best Entry-Level

The CMCST900D1 is CRAFTSMAN’s entry-level V20 trimmer, offering solid performance at an accessible price point. With over 2,000 reviews and a 4.4-star rating, it’s clear that this trimmer has found a loyal audience among budget-conscious homeowners. After testing it alongside more expensive options, I was impressed by how well it performs for the price.

The automatic .065-inch line feed eliminates the need for bumping entirely. The system automatically feeds line as needed based on cutting conditions. This works reliably for light trimming, though I did experience occasional jams when cutting through dense vegetation. Clearing the jam is straightforward, but it can be frustrating when you’re in the middle of a job.

The telescoping pole is a standout feature at this price point. I adjusted it to fit my 6’2″ frame comfortably, and the locking mechanism holds securely without any slipping or wobbling. Tall users who struggle with trimmers that are too short will appreciate this thoughtful design element.

Two-speed settings provide flexibility for different cutting conditions. I found the low speed adequate for routine trimming around the yard, while high power is necessary for tackling thicker weeds and overgrown areas. The ability to switch between modes helps extend battery life when you don’t need maximum power.

The included 2.0Ah battery is the main limitation. I averaged 15-25 minutes on high speed, which may not be enough to complete larger properties in one session. For small yards under 0.25 acres, this is sufficient. But if you have more ground to cover, you’ll want to budget for a larger 4-6Ah battery or a spare.

At 6.3 pounds, this trimmer is reasonably lightweight and well-balanced. The weight distribution is better than some competitors, with the battery positioned closer to the body for improved ergonomics. Conversion from trimmer to edger is quick and intuitive, taking just a few seconds.

Who Should Buy This

This is an excellent choice for first-time cordless trimmer buyers or those with small yards. The telescoping design makes it particularly well-suited for tall users who struggle with shorter trimmers. If you’re already invested in the CRAFTSMAN V20 ecosystem, the battery compatibility is another advantage.

Who Should Avoid This

Users with larger properties will want to upgrade to a larger battery immediately. Some units may arrive with dead batteries, but CRAFTSMAN’s warranty covers this – just contact customer service for a replacement if needed.

10. WORX WG170.2 – Best Lightweight Option

The WG170.2 is WORX’s best-selling trimmer for good reason. At just 5.5 pounds, it’s incredibly lightweight and easy to maneuver. I tested this trimmer for several weeks and found it to be perfect for quick trimming sessions where you don’t want to wrestle with a heavy tool. The weight savings is significant – after an hour of use, my arms felt much better than when using heavier 56V models.

While it may not have the raw power of premium units, for homeowners seeking the best string trimmers battery powered for simple maintenance, the 3-in-1 design transforms from trimmer to in-line wheeled edger to mini-mower. The twin rubberized wheels are particularly useful for edging, helping you maintain perfectly straight lines along sidewalks and driveways. I found the mini-mower mode handy for small patches of tall grass where getting out the full mower would be overkill.

Command feed technology provides instant line advancement with the push of a button. No bumping, no guessing – just fresh line when you need it. The button is conveniently positioned on the handle for easy access during operation.

The adjustability is impressive. Seven handle positions and six rotating head settings mean you can find the perfect configuration for any cutting situation. I used the low angles for trimming under deck railings and the high angles for reaching behind shrubs. The spacer guard protects flowers and ornaments from accidental damage, which is a thoughtful inclusion for detail-oriented gardeners.

Compatibility with WORX’s Power Share family means you can use your batteries across 75+ tools. If you already own other WORX 20V tools, this trimmer integrates seamlessly into your existing ecosystem.

However, the trimmer line durability is disappointing. The stock line is thin and breaks frequently, requiring constant feeding. The small spool size means you’ll be replacing spolls more often than with larger-capacity models. Upgrading to heavier aftermarket line helps, but it’s an additional expense.

Who Should Buy This

This is an ideal choice for users who prioritize lightweight comfort above all else. Seniors, those with limited arm strength, and anyone who does frequent short trimming sessions will appreciate the minimal weight. The extensive adjustability also makes it great for users who need to trim in tight spaces and awkward angles.

Who Should Avoid This

If you do heavy-duty trimming on large properties, the fragile trimmer line and small spool capacity will be frustrating. The edging wheel attachment can also interfere with cutting reach in tight spaces.

String Trimmer Buying Guide

Choosing the right battery string trimmer involves understanding several key factors. This buying guide breaks down everything you need to know to make an informed decision in 2026.

Voltage and Power – What You Need

Voltage is the most commonly cited spec for battery trimmers, but it’s often misunderstood. Higher voltage doesn’t automatically mean better performance. Here’s what you need to know:

20V-40V trimmers are ideal for small yards under 0.25 acres. They’re lightweight, affordable, and perfectly adequate for routine trimming of grass and light weeds. Most homeowners in suburban neighborhoods with typical lots will find 40V to be sufficient.

56V-60V trimmers represent the sweet spot for most users. These models deliver gas-like power with the convenience of battery operation. They handle thick weeds, tall grass, and overgrown areas that would stall lower-voltage models. If you have a medium to large yard (0.25-1 acre), this voltage range is optimal.

80V trimmers are designed for heavy-duty use and large properties over 1 acre. They’re often used by professionals who need all-day power. However, the increased voltage comes with increased weight and cost, which may not be justified for typical residential use.

Battery Life and Runtime Considerations

Runtime claims from manufacturers should be taken with a grain of salt. Real-world runtime depends on cutting conditions, your technique, and how you use the trimmer. Here are realistic expectations:

Light trimming (maintaining already-cut grass): Expect 110-120% of advertised runtime

Moderate use (weekly trimming with some weeds): Expect 80-90% of advertised runtime

Heavy use (thick weeds, tall grass): Expect 50-60% of advertised runtime

For small yards, a single 2-4Ah battery is usually sufficient. Larger properties may require a larger 5-6Ah battery or multiple batteries for continuous operation. Consider how quickly you can recharge – 45-minute charge times are common for premium models, while budget trimmers may take 4-8 hours.

Cutting Swath and Line Diameter

Cutting swath refers to the width of the area the trimmer cuts in a single pass. Larger swaths mean fewer passes to complete your yard, but they also require more power and can make the trimmer harder to control.

10-12 inch swath: Best for small yards and precision work. Easier to maneuver in tight spaces.

13-15 inch swath: The sweet spot for most homeowners. Balances efficiency with control.

16+ inch swath: Best for large open areas. Clears ground quickly but can be unwieldy in tight spots.

Line diameter typically ranges from .065 to .095 inches. Thicker line (.095) is more durable and handles heavy vegetation better, while thinner line (.065) is better for light trimming and causes less wear on the motor.

Weight and Ergonomics Matter

Weight distribution is more important than total weight. A well-balanced 12-pound trimmer will feel lighter than an unbalanced 10-pound model. Consider these factors:

Shaft material: Carbon fiber is lightweight and durable but more expensive. Aluminum is affordable but can bend over time. Steel is durable but heavy.

Battery position: Rear-mounted batteries improve balance but may feel awkward. Front-mounted batteries provide better reach but create front-heaviness.

Adjustability: Telescoping shafts accommodate different heights. Auxiliary handles should be positioned to minimize wrist strain.

Line Feed Systems Compared

The line feed system determines how fresh trimmer line is released during use. Each system has pros and cons:

Bump feed: Tap the head on the ground to release line. Simple and reliable, but can be finicky and releases line inconsistently. Most traditional trimmers use this system.

Auto feed: Line releases automatically based on cutting conditions. Convenient but can waste line by releasing too much. Works well for light trimming.

Command feed: Push a button to release line on demand. Gives you precise control and conserves line. Found on premium WORX models.

POWERLOAD: EGO’s revolutionary system that winds line automatically. Just feed line through the head and push a button. The easiest loading system available.

Battery Ecosystem Compatibility

Before committing to a trimmer, consider the broader battery ecosystem. Most major brands offer multiple tools that use the same batteries:

EGO 56V: Mowers, trimmers, blowers, chainsaws, saws, and more. One of the most extensive premium ecosystems.

Greenworks 60V/80V: Wide range of outdoor power equipment. The 60V and 80V platforms are not cross-compatible.

Makita 18V LXT: Over 300 tools across multiple categories. Ideal if you already own Makita tools.

WORX Power Share: 140+ tools using the same 20V batteries. Excellent for budget-conscious DIYers.

CRAFTSMAN V20: Growing ecosystem with decent selection. Good value for the money.

Brushless vs Brushed Motors

Brushless motors are superior in every way that matters for trimmers:

More power: Brushless motors deliver more torque and maintain speed better under load

Longer runtime: More efficient operation means 30-50% longer battery life

Longer lifespan: No brushes to wear out means the motor lasts significantly longer

Less maintenance: No brush replacement required

The only downside is cost – brushless models are typically $30-50 more expensive. But the improved performance and longevity make it money well spent in 2026.

Straight vs Curved Shaft Design

Both shaft styles have their place:

Straight shaft: Better for tall users, provides better reach under bushes and decks, typically more durable. Preferred by professionals and those with larger yards.

Curved shaft: More compact and balanced, better for shorter users, lighter weight. Ideal for small yards and precision trimming around flower beds.
