# Best robot mowers under £800 Source: https://mowandedge.co.uk/best/best-robot-mower-under-800 Publisher: Mow and Edge. Picks are based on what the Amazon listings state, not on hands-on testing. Method: https://mowandedge.co.uk/how-we-pick Cheaper robot mowers have improved a lot, but the savings usually show up in three places: a smaller rated area, a lower slope limit and an app that only works over Bluetooth near the mower. None of that matters if your lawn is small and fairly flat. It matters a great deal if it is not. This guide compares robots under £800, judged on the facts in each listing: the lawn area the maker rates it for, the steepest slope it allows, how wide it cuts, how you control it and whether the battery is in the box. Pick the smallest rating that still leaves headroom for your measured lawn, and check the slope figure if your garden runs uphill from the house. ## Products ### 1.
