Roborock F25 Ultra

Roborock F25 Ultra

The one for greasy kitchens: steam and hot-water modes, strong mopping, powered wheels and automatic detergent. Heavy, and the hot modes cut the battery short.

Our pick

Tineco Floor One Stretch S6

Lies completely flat to clean under sofas and beds, and washes and dries its own roller with hot water and air. Fiddly to fill, and only so-so at dry crumbs.

The short answer

Both lie flat to reach under furniture. The Tineco costs a lot less, is lighter and runs longer; the F25 Ultra mops better than almost anything else and adds steam and hot water for grease.
