Finding cheap / affordable robot lawn mowers doesn't mean settling for poor quality. Entry-level robotic mowers from brands like Worx and Landxcape now start from under £300 and handle most standard garden sizes with ease.
These budget mowers work by running on a boundary wire system that keeps them within your lawn. They charge automatically and mow on a set schedule. Most handle gradients up to 35% and cope well with lawns up to 500m².
A low-cost robot mower mulches grass clippings back into the soil which feeds your lawn naturally. Less work. Better results.
