Our verdict
A rare thing, an affordable corded mower with a real rear roller, so you can get a striped finish without paying for petrol or cordless. The 37cm deck and 40L box suit small to medium lawns, and the 6 height settings give decent flexibility. The trailing cable is the only real compromise.
Pros & cons
Pros
- Rear roller for stripes at a low price
- 6 cutting heights
- 40L collection box
- 3 year guarantee
Cons
- Corded, so cable to manage
- No mulching function
- Less powerful than petrol roller mowers

Buying second-hand
Roller mowers can collect debris around the roller, so check it spins freely and the box clips work. Around £60 to £70 used.
