Relatively silent, this flying saucer ... uh, sorry, this "robot broom" will show its effectiveness, mainly on pet hair. It happens everywhere: in sofas, beds, furniture, etc. and its static wipe collects all dust and small debris. The principle is simple, once it encounters an obstacle, it changes course. For a small fee, I think it's a fun gadget but not necessarily super efficient (for short to, you can really do without).
