This robot vacuum is an all-in-one vacuum and mop. It has a docking station that handles auto-emptying, washing, and drying, using room-temperature air to dry the mop. So other than occasional emptying and topping up of water, your work is always done.

"Tuning frictional behavior on the fly has been a long-standing engineering dream," said co-author Katia Bertoldi of Harvard University. "This new insight into how surface geometry governs slip pulses paves the way for tunable frictional metamaterials that can transition from low-friction to high-grip states on demand.” In addition, the dynamics revealed by these results are similar to those of tectonic faults and thus give scientists a new model for the mechanics of earthquakes, according to their new paper published in the journal Nature.
