The Best Cordless Strimmer Product Reviews - Our Picks
2-in-1 Grass Trimmer/Edger, 90° Head pivots, Command Feed System
WORX 20V Cordless Grass Trimmer
Dimensions: 113.2cm x 88.8cm x 31.1cm
Cutting Width: 16.5cm
Feed System: Command
This impressively versatile trimmer doubles as a wheel edger, making it all the simpler for you to tackle that annoying trimming and edging you won’t always reach with a mower.
Offering a spool system that allows you to take back control of your command feed, you’re always in control. What we really like about this cordless model is the fact that it’s great for using on slight gradients and slopes, too.
You can pretty much rely on straight edges with this system, too, making it a good all-around choice.
Best Budget Strimmer
VonHaus Cordless Grass Strimmer
Dimensions: 89cm x 21cm x 12.8cm
Cutting Width: 25cm
Feed System: Unclear
VonHaus is a fantastic garden product brand which often gets overlooked, and we really think this strimmer needs more attention. Priced at less than £60, it’s one of the most reasonable cordless trimmers on the market, offering a head that swivels 180 degrees, and 12 blades to tackle annoying edges and leftover bits of lawn.
This is one of the more impressive products in our list mainly thanks to the telescopic shaft. This extendable and contractable feature really makes it easy for you to adjust your trimming experience. It’s also compatible with various VonHaus lithium batteries.
We like this trimmer mainly because it is so versatile for the price. There’s a lot going on under the hood.
18V Cordless 28 cm String Grass Trimmer
Cutting Width: 28cm
Feed System: String feed
Black & Decker, of course, is a force to reckon with across all kinds of products. This particular garden product offers you a string feed system that’s often available at a great price.
Prices aside, this is one of the fastest-charging cordless trimmers, with your battery likely available to start using in just five hours after plugging in. It has a power select system, too, which means you can choose how to manage your battery life while tackling the lawn edges.
This cordless trimmer is amongst one of the best products for heavy duty use in our list – it’s pretty workable with long grass or thicker bits, making it ideal for small to medium lawns as well as longer stretches. It’s also unlikely it’ll ever clog up too often.
Cordless Grass Strimmer EasyGrassCut 18-26
Dimensions: 46.6cm x 22.4cm x 13cm
Cutting Width: 26cm

Bosch is another solid name in garden tool supplies we always look forward to writing reviews for. This fantastic series of strimmers offers a lot of power and a lot of manoeuvrability, which is naturally what you’re going to be looking for from these products – surely!
This version of the landmark Bosch garden strimmer has a good cutting diameter and batteries that you can also use in a variety of other Bosch products. This strimmer is ideal for continuous cutting and strimming, particularly thanks to its trigger-release feed.
We also like this particular 18V cordless cutting system for its ease of handling. There are plenty of trimmers out there which have aggressively uncomfortable handle grips! Bosch understands that ergonomics are the way forward, even if you’re just spending a few minutes here and there tackling a few lawn edges.

Generally, you can expect over 3700m of cutting length on each charge – that’s a lot of ground and lawn covered, and more than enough for the average trimmer buyer. It’s good value, even if a bit pricey.

This is a real transformer of a garden tool – it’s super-easy to flip this trimmer from an all-around cutter into a specialist edger in just a swift movement. What’s more, it’s one of the lighter products in our list, making it all the easier to move around with.

It benefits from an automatic feed system, making it really easy for you to pick back up again whenever you need to. There are even four different positions for the trimming head, making it impressively flexible, especially for the price.
The shaft on this trimmer is also telescopic, meaning that taller users won’t need to worry too much about losing control. The max cutting width of 30cm is really impressive for the price.

What’s really interesting about this grass strimmer is the fact that it comes with a handy foot pedal, which you can use to switch between cutting heights as and when you wish. This makes it a great all-around tool for trimming and edging.
As with many Bosch products, you can switch out a universal battery to use in this tool. You’ll also benefit from a swift auto feed, based on the Bosch Intellifeed technology.
Best Battery Life Strimmer
Swift 40V Cordless Grass Trimmer

Offering a nifty foot pedal system to help make switching to awkward edging nice and easy, you’ll also benefit from a smart telescopic shaft and an ergonomic handle. It’s one of the comfiest trimming products to handle on our list bar none.
What Are Grass Strimmers Used For?
Grass trimmers and grass trimmers are great for tackling those little bits of lawn which are just too unruly for your lawnmower to pick up.
Remember the last time you mowed your lawn or garden – were there little bits of grass left at the side of the edging? Did you miss a couple of blades sticking up here and there? Lawnmowers can only do so much.
For precision, grass trimmers are great. Cordless grass trimmers are even more popular because – as you can imagine – you’re not restricted by any nuisance power cords or cables. You get a lot more pull for your power, and you’ll generally find that these tools are powered by reliable lithium ion batteries.
Grass trimmer systems are great for getting into the real nitty gritty of your lawn, and they can be a real breeze to sweep around. They tend to use a line feed system rather than a traditional blade, too.
Ideally, you’d use a cordless grass trimmer, a line trimmer or a strimmer, to do your little bits of trimming and edging, or to apply that finishing touch to a particularly unruly lawn or garden.
Are Cordless Grass Strimmers Any Good?
The answer depends on the brand of grass strimmer you look for! However, there are drawbacks as well as positives to even the best cordless grass trimmers.
The good news is you have amazing freedom to move around your lawn and garden. You’re not restricted by the stranglehold of a cable, and this means it’s a great way to get some of the biggest gardens cut down to size.
However, you’re going to need to think about whether a traditional cordless grass strimmer is naturally going to be better than petrol trimmers. Petrol grass trimmer systems give you a bit more power and a bit more heft. Plus, there is the fact that you are not dependent on a battery, but rather however much fuel you put into your power tools.
It’s worth considering the downsides to even the best cordless grass strimmers, too. The fact is, a cordless grass trimmer is only going to go as far as its lithium ion battery will allow. This means you’re always going to be slightly limited to how far you can trim on a single charge. With a cabled grass trimmer, you can at least keep trimming for as long as the cable will allow you to stretch.
That said, whether you look at the best cordless grass trimmers or not, they are still amazingly convenient. They are ideal for small to medium gardens, they tend to be comfortable to use, and while the power may differ from model to model, you may even be able to get even longer grass cut down to size.
Should I Buy a Grass or Petrol Strimmer?
A petrol strimmer is still a cordless trimmer by nature and design, but there are naturally a few differences between those and the systems you’ve seen in this list.
Petrol strimmer systems won’t use a lithium ion battery, instead, you’ll need to use a fuel oil mix. This can help to give your strimmer some serious power. In fact, many people prefer the best grass strimmers in petrol mode than they do electric or battery models. They are just as easy to use, on the whole, and they might even give you more power.
However, a cordless strimmer with a li ion battery and charger is going to be more lightweight, less expensive to run, and is much more environmentally friendly.
What Should I look for When Buying a Cordless Grass Strimmer?
As you can see from our picks of the best garden tools in this line, there is a lot to choose between. Here are just a few of the most important factors to look at while shopping around.
Some cordless grass trimmers have batteries that last longer than others! If you have a larger garden than most, it’s naturally going to be a good idea to go for a longer charge or a more powerful battery. Run time is always important regardless of the type of line trimmer you’re looking for.
The handles on your cordless grass trimmer or strimmer will also differ. Naturally, they should be comfortable to use! You may find that there are some which offer loop handles, which allow you to be flexible with how to hold your tool and where you strim from. However, you can also find models with bicycle handles, too, which are great for scything and big swings.
The head on your grass strimmer or cordless grass trimmer is important, too. This is because you can buy some which rotate, meaning you can refine your edges, and some which allow you to go deep underneath things to trim where you can’t necessarily see.
As mentioned, cordless grass trimmers run on a line system. This will normally be a basic line which will wear out and break over time. But how do you replace that line?
There are some grass trimmers which have manual line feeds, which means that you’re going to need to pull the line back through yourself to keep cutting. There are bump feed systems, too, where you can simply tap your trimmer on the ground for the next line to come through.
Otherwise, you might find an auto feed system useful. Auto feed strimming means that you get a fresh line whenever you power up the grass trimmer. It just means you have to give the product a quick reboot!
A cordless grass trimmer is going to be something you’ll need to carry with you and wield, meaning you really should keep your own strength in mind. Not all strimmer models are going to be lightweight as factors such as the power, additional features and battery are going to weigh it down.
However, you will even find that lighter grass trimmers can give you a bit of fatigue every now and again. Therefore, it is a really good plan to look for a cordless grass trimmer model which comes with some form of shoulder strap and/or harness. This at least means that you can redistribute the weight slightly to somewhere that’s not going to give you horrendous aches and pains!
In our humble, collective opinion, buyer reviews, those which are fully verifiable, are ones you can trust. The fact is, no one grass trimmer is ever really going to be better than any others.
That’s why it is so important to find the best strimmer fit for you based on what other people have to say. Verified buyer reviews on online storefronts such as Amazon will fill you in on how well a grass strimmer works in practice, how heavy it is to move around, and whether the plastic blades are genuinely worth the price of admission.
Before you go ahead and throw your money behind a Flymo Contour or similar, make sure to check out what other buyers have to say. Reviews like theirs, and those such as ours in a buying guide or two, should give you that extra bit of confidence.
Finally, yes, you should be thinking about brands. We don’t tend to advise that the big brands are always going to be the best options, but it certainly doesn’t hurt to hold out for a manufacturer you recognise.
Black & Decker, for example, tends to be a good choice on the market for most home and garden tools. However, do also hold out for brands such as Flymo.
Can You Use a Strimmer Instead of a Lawn Mower?
You can, but it’s probably not the most efficient way to get a whole lawn done. Strimmers help you finish the job, really. In our experience, grass trimmers – cordless or otherwise – are great for tackling little jobs and leftover bits of edge and verge that a standard lawnmower can’t reach.
Even the best cordless grass trimmer, however, with a really impressive cutting diameter, will struggle to get through tons of thick stuff. Our advice would be to stick with a lawnmower if you have a large garden or lawn and need to cut it regularly.
