What owners praise
- Genuine petrol-equivalent power - owner reviews repeatedly describe it chewing through 3-week-overgrown damp grass that stalls budget cordless mowers, without hesitation.
- 60-minute runtime - enough for 700+ m² on a single charge. And the rapid charger gives you a full battery in 60 minutes if you do need a top-up.
- Self-propelled drive - variable speed, rear-wheel driven. Makes a 25.5 kg mower feel effortless, even on mild slopes.
- 70L grass box - enormous for a cordless mower. On a 700 m² lawn, expect a single empty per mow.
The drawbacks
- Price - £549 is steep for a cordless mower. You're paying for the 7.5 Ah battery and self-propelled system. Worth it if you have the lawn to justify it.
- Heavy - 25.5 kg with battery. The self-propelled drive compensates, but lifting it into a shed or over steps requires effort.
- No rear roller - at this price, a striping option would be nice. You get mild directional marks only.
- EGO ecosystem is expensive - batteries and tools are premium-priced. A second 7.5 Ah battery is £200+.
How it compares
The closest petrol rival is the Honda HRX 476 VK at £999 - the EGO matches its cutting performance at 55% of the price, with zero servicing costs. The Bosch UniversalRotak 36-550 at £329 is cheaper but vastly less powerful - suitable for medium lawns only. The Ryobi RY18LMX40A at £269 is the budget alternative but can't handle lawns over 400 m² on one charge.
Who should buy it
Owners of large UK lawns (500-1,000 m²) who are done with petrol servicing and want genuine cordless power. Ex-petrol users ready to switch without compromising on performance. Anyone who values the convenience of instant-start, no-fume, low-noise mowing.
Don't buy it if your lawn is under 400 m² (you're overpaying - Bosch or Gtech at half the price will do), if you need defined stripes (look at a rear-roller model), or if budget is tight (Ryobi ONE+ at £269 covers smaller lawns).
What owners actually say
Recurring feedback drawn from real owner reviews and forums. Attributed to source, not our own testing.
Owners rate it the closest cordless to petrol: the wide 52 cm deck and 56 V motor power through long grass, with a charge lasting close to the claimed runtime. The recurring gripe is ergonomics, not cutting.

"Ploughs into overgrown grass without slowing; the motor ramps up power to cope rather than stalling." Trusted Reviews
- LIKED
"Big wheels make straight lines and stripes easy, and one charge gives close to 50 minutes of real mowing." Trusted Reviews
- GRIPE
"The grass bag sticks out so you can kick it on every step at higher drive speeds, and there is no bag-full indicator." Trusted Reviews
- GRIPE
"The variable drive-speed controller is finicky to set to a comfortable pace." Lawn Care Forum
