Lawn maintenance is about more than keeping up with the next-door neighbor — your yard makes up a huge portion of your home’s value. And what’s one thing that’s sure to put off potential buyers? That’s right, it’s weeds. From pesky dandelions that speckle your lawn with dots of yellow to stinging nettle that protrudes from the cracks in your driveway, weeds are a nuisance. Sure, you can spray down the lawn with pesticides, but those can be dangerous to pets (not to mention your garden). A better solution is a cordless weed eater. It slices through weeds in an instant, shredding them to pieces. Plus, in a pinch, you can even use it like a lawnmower. Excellent for edging and excising invasive weeds, the power and utility of a weed eater is something every garage needs. Since it’s cordless, it’s critical to find something with a reliable battery or fuel source. To assist, we’ve compiled a list of the best cordless weed eaters on the market, along with some advice on making the right selection.

The Best Cordless Weed Eaters

If you want a way to cut through weeds efficiently that can enhance your overall landscaping appeal, the Greenworks String Trimmer is a worthy candidate. A battery-operated machine, this weed eater features a telescoping shaft. This lets you adjust the length of the main handle, enhancing your reach without compromising control. With a tilting head, you can cut through plant matter from a variety of different angles. You can shift it vertically, letting you edge with ease. If positioned laterally, it can cut through weeds quickly. The cord comes in a replaceable spool, extending far enough to cut through thick weeds without a hassle. Powerful enough to make light work out of outdoor upkeep, this is a quality cordless trimmer overall.

One thing to note is that, while the cordless nature of the trimmer gives you good range, the battery only lasts for a single-use. Be sure to recharge it every time you finish your yard work.

With a translucent fuel tank, you can always see how much time you have remaining. In terms of power, the 17-inch cutting range powerfully tears through plant matter.

When trimming, it cuts efficiently and evenly, limiting the need to go back over the lawn with a mower. Efficient and easy to use, this trimmer is a premium selection.

Looking for a trimmer to complement your larger-scale lawn care plans? Take a look at the Black + Decker Lithium String Trimmer for its simple yet effective design. At less than five pounds, it’s easy enough to move the trimmer around your yard. Even when reaching awkward angles, the long shaft makes it easy to access tricky spots without a struggle. Paired with the protective cover, even when you move the trimmer around, you don’t have an excessive risk of pieces hitting your eyes. The set comes with two rechargeable batteries so that you can always have one at full power. To add value, it comes with a leaf blower, so you can use the trimmer to cut down weeds and the blower to whisk them away.

It warrants a mention that, though this trimmer is powerful, you can’t change the angles of the head. This makes it trickier to edge evenly, particularly when tackling the side of your driveway.

Want a way to tackle an invasive weed species without reaching for pesticides? The Worx PowerShare Cordless Trimmer is a fantastic option, especially for small to medium yards. It features a comfortable handle with accessible controls, making it easy to activate the trimmer. The handle leads to a lengthy shaft, giving you optimal reach whether edging or trimming. Paired with the protective cover, it prevents small bits from hitting your skin. The head angles over a 90-degree range, letting you switch between edging and trimming. With a rubber buffer, it stops the top from migrating while you work. Paired with the foot-long reach, you can quickly tackle a small area on a single battery charge.

Shaft susceptible to rust

Do you prefer modern tech, reaching for the newest developments in lawn care equipment? In that case, the Swift Cordless Double Blade Trimmer can offer a lot of advantages. It features an unconventional design where, instead of using a spool of string, it relies on thick, sturdy blades. These are thick enough to slice through the stalks of even the most deeply-rooted weeds. Both the shaft and the handle are fairly unique as well. The shaft is relatively thin while the handle is straight, modeled more like a broom than a standard trimmer. Despite these tweaks, the powerful battery and strong spin slice through plant matter with almost incomparable efficiency. Ideal for overgrown areas, this trimmer meets even the most demanding standards.

It’s worth mentioning that the power of the blades can result in some stray pieces going flying once cut. This model lacks any real protection over the blades, so be sure to wear safety goggles when tackling your yard.

Key Features
  • Includes trimmer and leaf blower
  • Powered by a 40-volt battery
  • 10-inch cutting reach
  • Hits speed of almost 200 kilometers per hour

Touts a unique shaft and handle

Lightweight and maneuverable

CONS

Lacks ergonomic support

Minimal head coverage

Uses blades, not string

Especially if you don’t have a huge area to manage, getting a lawnmower may not make sense. That’s why many opt for something like the WorkPro Cordless String Trimmer, a tool that can function as a small-scale mower. It works as a trimmer and an edger, relying on a 20-volt battery to get through all sorts of plant matter. The string spins powerfully, protected by a shield built into the head of the trimmer. Coming with an extra two spools, the parts break off when their strength is spent. You simply push a button and, automatically, more material comes out of the included spools and get back to work. With controls accessible only from the handle, this trimmer is safe to use. It’s priced affordably and built to withstand a fair amount of wear and tear, making this trimmer a useful investment.

Keep in mind that, though this model is sufficient for smaller areas, the battery may drain before getting through a bigger yard. Unless you plan to use this simply for edging, it may be helpful to consider a more heavy-duty model.

  • Powered by a 20-volt battery
  • Comes with two spools of string

Best Cordless Weed Eaters Buying Guide & FAQ

When you choose a cordless weed eater, the first thing to consider is where you plan to use it. Do you need to tackle the landscaping of a massive backyard or are you simply looking to cut down the weeds overgrown on your driveway? These tools come in varying degrees of power, so it’s helpful to identify how you plan to use them before you move forward. 

Once you know the area the weed eater will address, you need to figure out whether you need it to work just as a trimmer or if edging is your priority. Trimming is the basic, lateral function, similar to whacking through a jungle. The results might not be precise, but the weeds will be gone. Conversely, edging is when you want precise lines like along the side of your driveway or by the path to your front door. By pinning down what you expect from the weed eater, you can narrow down the search and, ultimately, make the right pick. 

Do You Need a Cordless Weed Eater?

Any home or garage that has even the smallest lawn needs a weed eater (unless you plan to dig them all out by hand). The key is figuring out what specific benefits you desire. If you’re dealing with a weed invasion, power is likely what you are after. Look for something that is either gas-powered or has a backup battery, making sure the motor is strong enough.

Excellent for edging and excising invasive weeds, the power and utility of a weed eater is something every garage needs.

Many people with smaller yards use their cordless weed eater as a lawnmower. After all, if you’re only dealing with a couple of hundred square feet, a mower doesn’t make sense. A quality trimmer should be able to function in the stead of a conventional mower. Not only are they more affordable, if you choose a lightweight enough model, but they can also give identical results.

With a weed eater, you can address invasive plant species without delay. Instead of waiting for them to take over the area, you can cut them down right away. When properly used, a cordless weed eater can keep your yard looking ideal, adding to your comfort and overall curbside appeal.  

  • Can replace a conventional lawnmower for smaller areas. 
  • Cordless weed eaters are lightweight and easy to handle.
  • Small size optimizes reach so you can access tricky areas. 
  • Easy to store, fitting seamlessly into the corner of your garage. 
  • Work as both trimmers and edgers for complete lawn care. 
  • Versatile designs let you choose power sources and cutting edge.

The Most Common Types of Cordless Weed Eaters

Though the end goal of cordless weed eaters is always the same (getting through plant matter), there are a couple of different types. It mostly comes down to how it sources its power. This dictates the overall power of the trimmer and how long you can use it before needing to refuel. The type of cordless weed eater you need depends on how large of an area you plan to tackle. 

Gas-Powered

This type of cordless weed eater offers a substantial amount of power. It features a fuel tank close to the handle, running on two-stroke oil and gasoline. The fuel lasts for long periods, giving an even supply of power to the motor which spins the string. 

The controls sit near the handle of the weed eater. One is to deactivate the safety while the other is to turn on the motor. It is connected to either blades or a spool of string that spins. Rotating quickly, it slices through plant matter to give you a flat, even result. 

While gas-powered weed eaters are powerful and last longer, they tend to be heavier than their battery-powered counterparts. This can result in uneven cuts, especially when using the weed eater for trimming. Though they can go for a long time, they can be more tiring to use due to the extra weight.

Battery-Powered

Cordless weed eaters that rely on battery power are the most prevalent on the market. Most rely on a rechargeable, lithium-ion battery that is typically in the range of 20 volts. They connect to a charger which plugs into an AC outlet. Generally, the batteries will recharge within a matter of hours. 

This type of cordless weed eater has a standard design, featuring a handle with controls (including a safety). Connecting to a thin shaft, this type is generally lighter weight and easier to handle. It leads to a head that uses a motor to spin either blades or spools of polymer string. This is the part that cuts through the plant matter. 

Most battery-powered weed eaters incorporate an adjustable head. By turning on its side, the weed eater can work both as an edger and a trimmer. As a result, battery operated weed eaters tend to be more versatile. However, because of the high energy demand, they run out of juice faster than their gas counterparts. Aim for something with an extra battery whenever possible. 

What to Look for When Buying Cordless Weed Eater

When analyzing the value of cordless weed eaters, there are a few key things we considered. We looked at the repute of the brands and assessed reviews from those with firsthand experience. With those assurances, we looked next to the versatility of the weed eater. Aiming for models that work as trimmers and lawn edgers, we also tried to find options that can double as a lawnmower in a pinch. 

After deeming that the weed eaters were capable of performing multiple tasks, we looked next to the safety features. Not only does plant matter go flying once cut, once the string wears down, but it also breaks off. As a result, we prioritized the quality of the guard that covers the head. Another part of safety is the controls. The best cordless weed eaters have a safety button that has to be engaged to make the motor work (preventing accidental activation). 

Finally, we looked at the lasting ability of the power source. We selected models with batteries that charge quickly and hold onto power well. This way, you can get the most work done on a single charge or tank of fuel. Using these criteria, we compiled a list of the top options on the market.
