How Do Gtech Mowers Compare to Others?
When independent reviewers test Gtech lawn mowers against other brands, our models consistently stand out for their ease of use, thoughtful design and reliable performance. Ideal Home found the CLM50 made mowing "the smoothest experience I've ever had", while also praising its intuitive battery display and effortless setup. Trusted Reviews noted the SLM50 was "pleasingly powerful" and "incredibly easy to use", especially considering its ultra compact design.
"The CLM50 packs a punch despite fewer features than some mowers. Its higher price buys convenience and quality – the well made design feels easy to use with no complex operations." – Mark Haley, Easy Lawn Mowing (Gtech CLM50 Lawnmower Review).
What sets Gtech apart is the attention to practical details. Our Omniblade Cutting Technology in the CLM50 automatically increases blade speed when tackling thicker grass, while the collapsible grass box and foldable design mean storage is never a problem. The SLM50's vacuum style handle and featherlight weight make it perfect for anyone who wants lawn care to feel effortless.
What's the Best Cordless Lawn Mower?
What Is the Best Cordless Lawn Mower in the UK?
The best cordless lawn mower for you depends entirely on your garden size and how you like to work. Unlike corded electric mowers that restrict your movement and require you to work around the cable, our cordless battery powered models give you complete freedom to move around your garden.
For small to medium gardens (up to 250m²), the CLM50 offers the ideal combination of cutting width (42cm), runtime (40 minutes), and convenient features like grass collection and foldable storage. Its 48V battery delivers consistent power and charges in just one hour. The adjustable cutting heights from 30mm to 80mm give you complete control over your lawn's finish. The CLM50 in particular has earned praise from reviewers for its powerful cutting performance and intelligent Omniblade technology that adjusts power automatically.
For tiny gardens, courtyards, or those who need something incredibly light and easy to store, the SLM50 is unbeatable. At just 3.5kg, it's one of the lightest mowers available, yet Trusted Reviews found it tackled even long, wet grass with surprising effectiveness. Its 20V battery provides 30 minutes of runtime with a 4 hour charge time. While it doesn't collect grass cuttings, regular use means the fine mulch naturally feeds your lawn.
What's the Best Lawn Mower for Medium Sized Lawns?
The Lawn Mower CLM50 excels on medium lawns. Ideal Home's reviewer completed their lawn in just 10 minutes with no missed patches, describing it as "the smoothest mowing experience I've ever had." The intelligent Omniblade technology automatically adjusts blade speed when it senses thicker grass, increasing from 2800RPM to 3500RPM for tougher patches.
"Compact and foldable for easy storage. Adjustable elements of the mower are green coloured making them easier to find and use." – Good Housekeeping UK (10 best electric lawnmowers for a tidy garden).
What's the Best Lawn Mower for Small Gardens?
For compact gardens with limited storage space, the Small Lawn Mower SLM50 excels where larger mowers can't. Trusted Reviews noted it was "incredibly easy to move, with effortless manoeuvrability", while the ability to push it under benches and tables without moving furniture is a real time saver.
The body only option at £89.99 is particularly attractive if you already own the GT50 grass trimmer, as the handles and battery are fully interchangeable between the two tools.
How to Choose the Best Cordless Lawn Mower
Garden Size: How Much Can You Cut?
For very small gardens up to 20m², the SLM50 is perfectly sized and won't take up unnecessary storage space. For gardens from 20m² up to around 250m², the CLM50 offers better coverage thanks to its wider 42cm cutting width and longer 40 minute runtime. A simple rule: if you can't finish mowing in one 30 minute session, you'll benefit from the CLM50's extra capacity.
Weight & Manoeuvrability: How Easy Is It to Push?
The SLM50 at 3.5kg is extraordinarily light. Trusted Reviews described it as "effortless to manoeuvre" with its vacuum cleaner style handle making it easy to guide around garden features. The CLM50 at 13.5kg is heavier but still manageable, and Ideal Home noted it "felt light and easy" to push during mowing. If you have mobility concerns or prefer minimal physical effort, the SLM50 is hard to beat.
Your Grass Type: Short and Regular or Long and Thick?
For regular, weekly maintenance cuts, both models work beautifully. The SLM50 is designed for frequent, light cuts and uses mulching (no grass collection) to naturally feed your lawn. For lawns that sometimes get longer between cuts, the CLM50's grass collection bag and more powerful motor make it the better choice. Trusted Reviews found the SLM50 struggled with very long or wet grass, confirming it's best for regular maintenance rather than infrequent heavy cuts.
Storage Space: Where Will It Live?
Both Gtech mowers are designed with storage in mind. The CLM50 features a collapsible grass box and foldable handle, making it compact enough for most sheds or garages. Ideal Home's reviewer particularly appreciated this feature. The SLM50 is even more space efficient, taking up barely any room thanks to its tiny footprint. If storage is at a premium, the SLM50 is the clear winner.
Grass Collection vs Mulching
The CLM50 collects grass clippings in its 50 litre bag, giving you a tidier finish and making it easier to dispose of cuttings. The SLM50 is mulching only, which means grass cuttings fall back onto the lawn. For regular maintenance cuts (where you're only removing a centimetre or so), mulching actually benefits your lawn by returning nutrients to the soil. However, if you prefer a pristine finish or cut less frequently, you'll want the CLM50's collection system.
Cutting Height Flexibility
The CLM50 offers six cutting heights from 30mm to 80mm, adjusted via an easy to use handle. This gives you complete control over your lawn's appearance, from putting green short to longer, lusher growth. The SLM50 offers two heights (40mm and 50mm), which Trusted Reviews noted was "pretty impressive" for such a compact mower, though adjustment is slightly more involved as you need to flip the cutting deck.
Battery Charging Time
The CLM50's one hour charge time means you can quickly top up between uses or even charge while having a break if tackling a larger area. Ideal Home's reviewer noted three of four battery indicators remained lit after 15 minutes of mowing, suggesting excellent efficiency. The SLM50's four hour charge time is longer, though Trusted Reviews pointed out this is less of an issue when you're only mowing small areas that take 10 to 15 minutes.
Whether you're maintaining a tiny courtyard lawn or a medium sized garden, there's a Gtech cordless lawn mower designed for your needs. The CLM50 delivers professional results with convenient features like grass collection and intelligent cutting technology, while the SLM50 proves that great things really do come in small packages.
