Cordless Lawn Mowers

Powerful Electric Battery Lawn Mowers

Cordless lawn mowers have become the go-to choice for modern gardeners, combining the cutting performance of traditional petrol mowers with the convenience of a lightweight, battery-powered design. No cables, no pull cords, no petrol and no fumes.

For medium to large gardens, the CLM50 delivers powerful cordless performance with a 42cm cutting width, intelligent power control and a 50L grass bin, making short work of thick or wet grass. For smaller lawns and tighter spaces, the SLM50 is a compact, single-handed mulching mower that feeds nutrients back into your lawn with no bin to empty.

Both models are powered by advanced lithium-ion batteries, charge in just one hour and are designed to make lawn care cleaner, quieter and simpler. Already own a compatible Gtech tool? The SLM50 Body Only lets you share your existing battery across the range.

Battery Lawn Mowers FAQs

Both Gtech battery lawn mowers (the CLM50 and SLM50) take just 1 hour to charge – making them our fastest charging mower batteries ever. This quick charging time means there's less downtime, and more time to tend to the grass.
From one full charge, both the CLM50 and SLM50 models feature 48V lithium-ion batteries that provide a runtime of up to 40 minutes. This is sufficient for most garden sizes, with the CLM50 handling medium to large gardens and the SLM50 perfect for smaller spaces.
The CLM50 is equipped with our biggest ever 50-litre grass bin for convenient collection and disposal. The SLM50 small lawnmower does not have a grass bin - instead, grass cuttings naturally decompose and self-fertilise the soil, keeping your lawn healthy without the need for emptying.
Yes, both our cordless lawnmowers are upgraded for maximum performance. They feature enhanced airflow systems that move grass cuttings to the bin quickly and efficiently. Both the CLM50 and SLM50 have lightweight frames making them easier than ever to manoeuvre around your garden, with the CLM50 featuring intelligent power control that automatically adjusts motor power for optimal performance.
Our CLM50 electric lawn mower uses a single blade with a cutting width of 420mm, ideal for medium to large sized gardens. For smaller garden spaces, the SLM50 small lawn mower has a reduced cutting width of 250mm, perfect for narrow spaces that bigger mowers cannot access.
All our electric lawn mowers are covered by a 2-year guarantee. However we design all our products to last well beyond this timeframe. If there is ever any issue, our in-house customer service team is always on hand to help keep your lawn mower running for as long as possible.
Not all battery lawn mowers can tackle wet grass, but our CLM50 lawn mower features intelligent power control that automatically adjusts motor power, providing less energy on short grass and more energy on longer or wet grass. This allows our CLM50 to effectively cut grass whether short, long, or wet. Find out more in our guide on cutting wet grass.
To tackle overgrown grass, begin by using a grass trimmer to carefully trim down the taller, more unruly sections, reducing the height gradually. Once the grass is more manageable, finish up with your cordless lawnmower for a neat and tidy lawn.
