Cordless strimmers are becoming increasingly popular, allowing users to quickly and easily trim the edges of their lawns and other hard-to-reach spots around the garden, without being tied back by cords and cables. We spent 20 hours looking through reviews of various models in order to identify the 10 best cordless strimmers on the market today.

BLACK+DECKER 18V Cordless 28 cm String Grass Trimmer

It offers adjustable power options too, letting you save energy on shorter grass and crank up the power for cutting thicker patches of graden grass. When the battery needs charging up, you’ll need to wait around five hours to get it back to 100%. With 28cm of cutting width, this Black + Decker cordless strimmer can provide quick and easy trimming along long stretches of lawn. It almost feels like a mini mower with its cutting potential, and it comes with an automatic single line feed system that helps to minimise the risk of wasted line and reduce the need for regular maintenance too.

It weighs in at only 1.7kg, making it really easy to lift, carry, and move around, great for those extended trimming sessions.

Are cordless Strimmers any good?

Yes, there are plenty of high quality cordless strimmers out there, and more and more people are opting for cordless models due to the benefits they can provide. As leading consumer guide Which points out, “Cordless grass trimmers let you carry out jobs around the garden and allotment without worrying where the nearest plug socket is.” (1)

This is one of the key benefits of cordless strimmers; they allow you to move around the lawn more freely, without being held back or limited in any way by the length of power cables and extension cords. This can be highly beneficial for those who have large plots of land, big gardens, or allotments that aren’t conveniently close to any power outlets.

What’s more, cordless strimmers come in a huge range of types, from high-powered petrol machines that can tackle massive patches of weeds and overgrowth without any fuss to more lightweight and compact battery-powered models that have the benefit of being more eco-friendly and quieter while running too.

In spite of all this, it’s worth mentioning that there are some downsides to cordless strimmers, most notably the fact that you can’t keep them running non-stop. Eventually, the batteries will wear down and need to be charged back up or the petrol tank will empty out and need to be refuelled.

What’s the difference between a trimmer and a strimmer?

There is no difference between the terms strimmer and grass trimmer. Many people can make the mistake of confusing these two terms or worrying that one of them is very different to the other, but the truth is that they’re both used to describe the same devices.

The word ‘strimmer’ is simply a shortened version of the term ‘grass trimmer’, and you may find that some brands tend to label their products as strimmers while others favour the term grass trimmer, but they’re both referring to the same kind of tool, i.e. one that makes use of blades or trimmer line to cut through grass and weeds.

It is, however, important to note that a ‘brush cutter’ is not quite the same as a strimmer or grass trimmer. Brush cutters often feature a metal blade inside the head and are designed to tackle bigger workloads and tougher patches of foliage, such as nettles, briars, and brambles. So if you have some of these tougher, thicker patches around your garden, you might want to opt for a brush cutter.

What size strimmer do I need?

When we talk about strimmer size, it’s important to understand that the size of the unit itself can have an impact on how comfortable and easy it is to use. Older users or those with aches and pains may prefer to find a very lightweight and compact model, while others won’t mind something bigger and bulkier.

Often, the best cordless strimmers are able to offer a telescopic handle. This allows you to change the length of the handle in order to suit your height. Taller users will need longer handles, while shorter users will want to minimise the length of the handle in order to use the strimmer comfortably.

WhatShed Top Tip – If you plan on sharing your strimmer with other users, try to find one with a highly adjustable handle

As SPS Engineering explains, it’s important to focus on the type of strimmer, as well as other factors, in addition to its size, in order to find one that’s just right for you. (2) You need to think about the cutting width, for example, which shows how much grass the strimmer can cut on each pass, as well as its power source, run time, battery charging times, and more.

It’s only by taking these different factors into account and considering all the options that you’ll be able to find the perfect strimmer to meet your needs. If you have a large lawn and do a lot of trimming, for example, you may need to prioritise a model with a long run time or a petrol model, or if you need to do a lot of lawn edging, you’ll need to find one with an edge wheel feature.

How do you stop a strimmer line from breaking?

One of the issues that can occur when using a cordless grass trimmeris that the line may break over time. This is a regular part of a trimmer’s functionality, and you can’t expect the line to stay intact forever. Most trimmers even come with built in automatic feeding systems to feed fresh line out as the older parts break off, but there are actions you can take to reduce the risks of breakages.

For instance, it’s wise to read through the instructions of your chosen trimmer and see what the manufacturer recommends in terms of general usage. Often, manufacturers will provide clear instructions regarding how and when to use a trimmer, along with tips that can help you minimise the risk of line breakages and maximise the lifespan of each set of line.

In general, when using your grass trimmer, you’ll want to make sure you only use it on grass and weeds that it can cut. If you expose the line to harder surfaces or accidentally hold the strimmer too close to garden paths and slabs, it will be more likely to break.

WhatShed Top Tip – If you find your line breaking too often, consider making use of a thicker line

It’s also important to think about the conditions of the ground before you start strimming and avoid using your strimmer if the conditions aren’t right. The RHS, for instance, advises against lawn work in general when the grass is wet or frosty. (3)

Certain grass trimmers will not be too well-suited to cutting thick grasses or weeds, due to a lack of power, so lines will break off much more frequently if you try and use your trimmer for work it isn’t capable of. You may need to find a more powerful model if you have lots of weeds and overgrown areas around your garden.

Are Strimmers with plastic blades any good?

As well as models with spools or pieces of line, it’s also possible to find some trimmers with blades in the head. The blades spin around at high speeds, powered by the motor, in order to chop through the grass or weeds.

There are certainly some advantages to these models. For starters, they require way less maintenance and there are fewer things that can go wrong. Since you don’t need to worry about feeding out fresh line or having to deal with line breakages, you can simply use your trimmer consistently and only need to stop and replace blades if they break.

The strength of the blades can vary from model to model. Some of them will be more than strong enough to tackle weeds and thick grasses, while others will be weaker and break more often, so it’s recommended to read user and expert reviews in order to find a model that can meet your needs.

It’s also worth noting that you can find bladed strimmers with various power sources. Some are corded, others will be powered by petrol, and others have batteries. So, if you’re considering a bladed model, you have a lot of options to choose between, and each style has its advantages.

Corded models have the benefit of not running out of power. Petrol mowers tend to be the most powerful, and as Christ Church College notes, battery models have the key advantages of being quieter and more friendly to the environment. (4)
