What owners praise
- The weight - it is one of the lighter cordless mowers in its class. Owners report carrying it over a 20 cm garden step is genuinely easy.
- The big grass box - 50 L is generous for a 42 cm cordless mower and means fewer trips to the compost heap on a typical lawn.
- The British design feel - there's a friendliness to the way the handle folds, the way the battery clicks in, the cut-height lever. None of it is revolutionary; all of it is nicer than the rivals.
- Battery life is honest - the single 2.0Ah pack covers up to around 400 m² per charge, and owner reports broadly back that up on dry grass.
The drawbacks
- No defined stripes - it uses a rear comb, not a roller, so it won't give you the striped finish a roller mower does.
- No mulching plug in the box - at £249 this is annoying. Plug is £19.99 extra.
- Proprietary battery - fits only other Gtech outdoor tools. If you want shared batteries with your drill, Ryobi or Bosch make more sense.
- Replacement battery cost - £80-£100 in 6-8 years. Not catastrophic, but Bosch Power for All packs are around £60.
How it compares
The most direct rival is the Bosch UniversalRotak 36-550 at £329. Both carry a 50 L box; Bosch wins on its 36V Power for All shared battery system. Gtech wins on weight, ergonomics and the friendlier user experience. The Ryobi RY18LMX40A at £269 is the value pick if you already own ONE+ batteries - much wider tool ecosystem, but heavier and less polished.
Who should buy it
First-time cordless mower buyers with a small-to-medium UK lawn (up to around 400 m²) who want a friendly, light, no-fuss mower. Anyone older or with back/arthritis trouble who finds heavier mowers tiring. Anyone who values build refinement over cross-tool compatibility.
Don't buy it if you want defined lawn stripes (rear comb, no roller), if your lawn is well over 400 m², if you already own Bosch / Ryobi / DeWalt batteries, or if you're building a complete cordless garden tool kit from scratch - in those cases the Bosch UniversalRotak or Ryobi 36V MAX are better-positioned.
Where to buy
The Gtech CLM 2.0 is sold mainly direct through gtech.co.uk and on Amazon UK. Pricing is consistent across both - Gtech direct often includes free delivery; Amazon often ships faster. This review tracks UK pricing across both and is updated when there's a deal worth knowing about.
What real owners say
Owner opinions on the Gtech CLM and cordless mowers in this price bracket from r/GardeningUK and r/lawncare. Here's what keeps coming up.
"My parents have (I think) a GTech which has been going the last couple of years (at least) and manages their lawn really well on one charge (~15m x 20m)."
- u/knotmidgelet, r/GardeningUK
"They are much better than you'd think. I bought the smallest Husqvarna last year and it's a monster for cutting through stuff. Only downside is the grass box is a bit small. Battery can also be used in strimmers, hedgecutters, blowers etc."
- u/UsefulAd8513on cordless mowers generally, r/GardeningUK
"After my petrol died and wouldn't start / stay started despite stripping it back and cleaning it out, I went electric. I'd never go back to petrol. They're so convenient!"
- u/pspspsreddit, r/GardeningUK
"Swapped from self-propelled petrol to cordless last year and love it. It's so much lighter that I don't miss the self-propelling. No servicing, filling petrol cans, troubleshooting starting problems... just charge and go."
- u/GnirobSW, r/GardeningUK
The pattern across UK Reddit threads: people switching from petrol to cordless almost universally don't go back. The Gtech specifically gets praised for being light and easy - the battery ecosystem lock-in is the consistent caveat, which matches this assessment.
What owners actually say
Recurring feedback drawn from real owner reviews and forums. Attributed to source, not our own testing.
Owners love the 50 L box and how simple it is to live with, but two complaints recur: it can cut out on the lowest height settings, and real runtime falls well short of the claim on long or damp grass.

"The 50 L grass box is far bigger than most cordless rivals, so far less stopping to empty it." EasyLawnMowing

"It keeps cutting out on the lowest cutting height when the ground is uneven and the blade catches." Owner reviews, EasyLawnMowing

"Real runtime is closer to 20 minutes than the headline figure once the grass is long or wet." Owner reviews, EasyLawnMowing
