Contrary to our first impression, the Roborock S7 Max Ultra is not another superfluous member of the S7 family, but actually the best.

In all models, the washing and tank system proves to be a real help at work. In the search for the right high-tech cleaning power, other differences therefore come into focus...

Cleaning robots promise that you will never have to vacuum or mop again. Stiftung Warentest regularly tests what the robots can do on hard floors or carpets, how thoroughly they mop and what they are good at in practice. There are many good models, but the price differences are large: Between 160 and 1400 euros.
