Never vacuum or mop yourself again - that's the promise of cleaning robots.

Product details
Clean floors at the touch of a button: The smart mopping robot RCF 3 now takes care of the tedious and time-consuming wet mopping of hard floors. Thanks to the proven FC roller technology, the RCF 3 not only removes stubborn dirt or dried liquids but also loose dust and dry crumbs. It automatically detects carpets and skillfully avoids them. The RCF 3 features two tanks that allow it to continuously supply fresh water to the roller while collecting dirty water separately. Light, dry dirt is effortlessly picked up and also directed into the dirty water tank. With the practical app control, various cleaning modes can be set. The robot can be flexibly adapted to different needs and requirements. For cleaning, the robot can be conveniently started via the app or by pressing a button on the device. If the RCF 3 needs assistance, it communicates this in many situations through voice output or via the app.

This model can only mop, but it does so precisely and thoroughly. Instead of a mop or round cleaning pads, Kärcher has given its appliance a roller for mopping and this works very well in practice. The set even comes with cleaning agent.
