Best Cordless Weed Eater Reviews

1. Makita XRU09PT1 Trimmer Kit

The Makita XRU09PT1 Trimmer Kit is a fantastic weed eater because it comes with everything you need to start using it immediately.

Equipped with four batteries, a charging port, as well as some weed trimmer line, it’s one of the better options you can get your hands on.

Product Highlights

The most notable feature of this trimmer is that it has a brushless motor, which offers optimal power and incredible longevity when compared to brush motors.

With the direct-drive system, you’ll have increased torque and power to work through thick vegetation with far less effort, making it one of the better choices for big pieces of land.

You’re also going to love the variable speed trigger, which allows you to manage the speed of the trimmer to your desired level.

The Makita XRU09PT1 Trimmer Kit has two main speed options: low, which is 5,000 RPM, and high, which allows for 6,500 RPM.

As the operator, you’ll find that these impeccable speeds are relatively easy to control and can work their way through an assortment of grasses, vines, and dry brush.

Fortunately, the trimmer kit also comes with a bump-and-feed trimmer head, which allows you to seamlessly feed more while in the middle of a task.

Along with the four included batteries, you will also receive the trimmer with a pre-loaded 0.080-inch twisted quiet line.

Another function to note is the reverse rotation, which allows you to clear any weeds or debris that could be clogging the head of the trimmer.

What to Like About It

Compared to some of the other weed trimmers you’ll find, this model is much quieter while in operation, especially as it runs off batteries instead of fossil fuels.

You’ll also love how easily it can be controlled and held for extended periods, even if you have limited experience with using a weed trimmer.

Overall, you can expect to use as little as 25% of the battery life by the time you’ve finished working on a midsize property.

What Not to Like About It

The most massive issue with the Makita XRU09PT1 Trimmer Kit is that the bump and feed head is poorly designed.

As such, the line has the tendency to get stuck frequently.

You might also find that the line head holds less line than you would hope, mostly if you were to compare it to a gas-powered model.

Pros:

  • Low-noise operation
  • Easy to use
  • Impressive battery life

Cons:

  • The line gets stuck easily
  • Less line storage

2. WORX WG191 Cordless String Trimmer

One of the main advantages of the WORX WG191 Cordless String Trimmer is that it is said to have gas-like performance but runs with zero emissions, thanks to its battery-powered design.

With an assortment of useful features that you will love to have on your new weed trimmer, it’s a wonderful choice for everyday use or weekly lawn maintenance.

Product Highlights

Similar to most high-quality weed trimmers, this unit features variable speed control that allows you to make the tool far more versatile for your needs.

This feature also helps to preserve more battery power.

You’ll find a select speed trigger that you can engage to access the extended battery power and reserve power so that you can cut through thick brush with ease.

Another exciting feature of the WORX WG191 Cordless String Trimmer is its spool feeding system, allowing you to capitalize on the on-demand line feeding instead of a bump-and-feed system.

There are lithium-ion batteries that arrive with the weed trimmer, which are notable for their long-lasting power and quick charging capabilities.

You’ll also notice a built-in battery indicator that will let you know when it is time to recharge the power source for your new weed eater so that it’s always ready to use.

The pivoting cutting head is also quite essential to note, as it allows you to tackle any type of terrain.

Whether it be narrow, straight, or jagged, you can pivot the tool from zero to 90 degrees.

In terms of ease of use, the rotating rear handle enables you to have better control over the device when getting into hard-to-reach areas.

Also, you can easily convert the ordinary string trimmer into an edger with inline wheels for exceptional cutting capabilities.

Upon the arrival of the WORX WG191 Cordless String Trimmer, you’ll also get a 0.080-inch professional-grade trimmer line that is far longer-lasting than traditional kinds of wire.

What to Like About It

Advancing the string on this weed eater is one of its most straightforward features, as the button is located directly next to the throttle for easy access.

You will also find that its substantially easier to feed a new line when needed, compared to bump-and-feed line systems.

Many have also noted the battery lasts much longer than initially thought, allowing you to complete a full day of work by using half, if not less, of the battery power.

What Not to Like About It

Unfortunately, battery replacements for the WORX WG191 Cordless String Trimmer are very costly, and not having a second battery to use can be inconvenient if you forget to charge your original one.

Also, the line that is included with this model wears down much quicker than you would think, so you will want to consider having an extra spool on-hand.

It’s essential to be wary of weed whacking near hard surfaces, such as concrete, as it will break the line quickly.

Pros:

  • Good battery life
  • Easy line feeding
  • User-friendly variable speed

Cons:

  • Only one battery
  • Low-quality trimmer line

3. EGO STA1500 String Trimmer Attachment

If you already own an EGO Power+ Power Head, you’ll love having the EGO STA1500 String Trimmer Attachment at your disposal, as it is a significant upgrade from existing models.

With incredible cutting power and several user-friendly features, you’ll quickly want to put your new tool to good use.

Product Highlights

This weed trimmer attachment is exclusively compatible with the EGO Power+ PH1400, which is sold separately.

Instead of being a standalone weed trimmer, it can easily be attached to the existing unit to provide you with even more user-friendly features that you’ll love to have.

One of its best features is the rapid reload trimmer head, which allows you to install and rewind your trimmer line much faster than ever before.

Another notable feature of the EGO STA1500 String Trimmer Attachment is that it has a fully water-resistant (IPX4) design, which makes it a fantastic partner for working with wet and moist debris.

The 15-inch cutting swath gives you more than enough width to tackle a variety of areas around your property, and the bump-head line advancement is something you’d see on professional-grade models.

With your order, you will also receive a pre-loaded 0.095-inch cutting line.

The gears for the cutting head are encased in an aluminum alloy enclosure, which protects them from fall damage and keeps the internal components safe during the off-season.

Also, it is compatible with a brushless motor that will last you many years.

What to Like About It

The power within the EGO STA1500 String Trimmer Attachment is what makes it worth the investment.

It runs on a motor that is strong enough for you to work through any type of grass with ease.

The high-quality line that is included with this attachment helps to boost its versatility, as it will easily slice through thick vegetation like butter.

Also, the feeding process for your trimmer line is likely one of the best you’ve used, with little chance of the line getting stuck.

What Not to Like About It

If you don’t already own the EGO Power+ PH1400, you won’t be able to use this attachment, which means you will have to invest in the other components to make this unit work.

Another disadvantage is its weight. The trimmer head feels very bulky when paired with the battery, offering limited balance when compared to other models.

Pros:

  • Very powerful
  • High-quality trimmer line
  • Easily feeds line

Cons:

  • Needs extra components
  • Bulky design
  • Poorly balanced

4. Greenworks 2101602 40V Cordless String Trimmer

There are multiple models for you to choose from, which would depend on the battery power you need based on the size of your property. This ranges from 2Ah batteries to 4Ah batteries.

With a list of simple features, this model is easy to use and will give you the confidence to take better control over the aesthetics of your property.

Product Highlights

As such, you will be able to use a single battery to power over 25 tools that they have in their catalog, which makes it an excellent option if you already own Greenworks lawn equipment.

With double the power of a traditional 20V battery, not only does this tool pack a powerful punch, but its battery resilience is also quite impressive for big-scale jobs.

We’re also sure you’ll like the 12 inches of 0.065-inch line that comes with the unit, already fed into the auto-feed head.

The auto-feeding feature is also something to consider. With this, you simply push a button if you want more of the line to be fed into the cutting head.

Also, the Greenworks 2101602 40V Cordless String Trimmer is ergonomically designed to offer superior balance and a more comfortable handle.

With the help of the 12-inch cutting path, you’ll be able to manage grass, weeds, and other types of brush with a single pass.

With a low-noise operation and a lightweight design, it’s easy to see why this tool is one of the more user-friendly models on the market.

You’ll also find that it’s a comfortable weight for elderly property owners, and it has far better balance than you would expect.

On average, you can expect to use less than 50% of the battery while trimming the grass around your property.

What Not to Like About It

The inability to adjust the length of the weed trimmer might make it a little uncomfortable to use, especially for taller homeowners.

You might also find that the guard is minimal, which means you have to get quite close to the area you are cutting. Obviously, this could put gardens and vegetation at risk.

Pros:

  • Long runtime
  • Comfortable weight
  • Well-balanced
  • Efficient battery

Cons:

  • Non-adjustable length
  • Small guard

This cordless and battery-powered string trimmer is a reliable solution for most properties, especially if you’re searching for a weed eater that doesn’t produce emissions.

The performance of the Earthwise LST02010 Cordless String Trimmer is quite impressive.

It also isn’t too bulky to use for extended periods and has remarkable battery life.

Product Highlights

The Earthwise LST02010 Cordless String Trimmer has a 20V 2Ah lithium-ion battery that charges quickly and offers a few hours of use in a single charge.

You’ll also find that with the help of the included fast charger, you can quickly recharge the battery to full within an hour.

The runtime is easily one of the most notable highlights of this unit; it will allow you to manage your property with a single charge easily.

Homeowners will find the 10-inch cutting width is useful for most projects, although it might not be as large as some other weed eaters that have cutting paths as high as 15 inches.

The auto-feed feature is also convenient, as it allows you to engage a button to feed more of the included 0.065-inch nylon line into the cutting head.

Pros:

  • Included battery warranty
  • Lightweight and ergonomic
  • High-quality build

Cons:

  • Poor battery
  • Small spool

Buyer’s Guide

Choosing the best weed trimmer can take a sufficient amount of research, especially if you need a tool that offers a lot of versatility while still being user-friendly.

Fortunately, there are several points in this buyer’s guide that can help you to know what to look for in the best model.

1. Motor

There are two main types of motors that you will find in weed trimmers: brushed and brushless.

Brushless motors are touted for their impressive longevity, primarily if you’re investing a lot of money into a weed eater.

You’ll find that brushless motors help to dissipate heat quickly, preventing the unit from overheating due to less friction with brushed motors.

Brushed motors, on the other hand, are typically less expensive because they use carbon components to push power through the unit instead of magnets.

Although they are the most cost-effective, they also lack in performance and could cause your weed eater to overheat after several minutes of use.

2. Speed

The speed of your weed trimmer is something to think about, as well, as it will determine how quickly you can power through different types of vegetation.

When considering this feature, you will want to think about the type of vegetation you have on your property.

You might not need a trimmer with a high RPM if you are only working with thin blades of grass.

However, if you have a thick brush to power through, you’ll want the highest level of RPM that you can manage with your skill level.

Most homeowners find that weed eaters between 3,000 and 5,500 RPM are more than powerful enough for everyday tasks.

However, if you have unusual terrain, such as in commercial lawns, you can find models as powerful as 15,000 RPM.

3. Line

Most of the weed trimmers that you look at also come with a built-in line that makes the unit ready to use right out of the box.

With that said, you’ll want to make sure the included line will be useful for your property; otherwise, you will have to invest in some extra line.

Ideally, you will want to find some weed trimmer line that is 0.065-inch in width, and that is twisted. This is one of the most powerful that you can get your hands on.

The square line is another useful option if you need a high-powered line that will cut through thick weeds with ease.

On the other hand, the round version is the most basic and all-around reliable option for traditional grasses and debris.

4. Battery

The battery of your new weed trimmer is one of the essential features to think about, as it will be the power source for the entire unit.

If you invest in a tool with a shoddy battery, you might find yourself spending an additional $100 to $200 for a replacement.

You’ll want to opt for a unit that has a quick-charging battery that also lasts several hours before dying, allowing you to tackle large scale projects with ease.

It’s also a good idea to find a model that has more than one battery, so you can easily switch them out in the middle of a job if necessary.

Fortunately, most weed eaters come with lithium-ion batteries, which are known for their energy retention as well as their long-lasting power.

5. Water Resistance

Although you might not ever have to trim or edge your property while it is wet, having a weed eater with water resistance can be a formidable way to protect its interior components over the years.

With a water-resistant model, you won’t have to worry about getting caught in the rain or having moist vegetation get stuck in the cutting head.

Cordless Weed Eater FAQs

1. How does a weed eater work?

Luckily, weed eaters typically have a very user-friendly design that will be easy for first-time users to put to good use.

You’ll first want to make sure the batteries are fully charged before inserting them into the weed eater.

Also, you would want to check that you have a couple of inches of line fed through the head.

If you’re lucky enough to have an auto-feed feature on your device, you simply engage a trigger or button for the unit to automatically feed the line for you.

Holding the weed eater at an angle, you push the power button or pull the power trigger to engage the tool, starting the engine.

By pressing on the variable speed control trigger, you will be able to choose from different speeds for more or less powerful cutting.

Ensure that you maintain the appropriate angle for the vegetation you’re tackling so that you can evenly trim your grass or edge your garden with ease.

2. How long does a cordless weed eater last?

Depending on the build quality and battery quality of your weed eater, some units can last anywhere from one hour to several hours.

You will also want to take other factors into account, such as controlling the speed, as the less speed your weed trimmer is using, the longer the battery will last.

On average, a fully charged battery should give you two to three hours of continuous use with a regular model.

3. Can you make your battery-powered weed eater more powerful?

Unless you are very experienced with mechanics and engineering, the only way to make a battery-powered weed eater more powerful is to invest in a more robust battery or to replace the unit for a more powerful option.

For example, if the stock battery for your trimmer is 2Ah, you can consider upgrading the battery to a 4Ah for more available power.

Also, it’s essential to make sure the batteries in the trimmer are fully charged so that you have access to the full potential of the tool.

Our Final Recommendation

After careful comparison, we found that the best cordless weed eater is the Makita XRU09PT1 Trimmer Kit.

This kit comes with everything that you need, including four batteries, a charger, and a trimmer line.

Its performance is rather impressive, too, and although it looks heavy-duty, it’s relatively easy for beginners to control and use for a variety of outdoor projects.

The only feature we wish it had was automatic feeding, as the bump feed system is poorly designed.
