It's a gadget. This robot brush does its job quietly, provided everything tidy at home and not too dusty. If you live in the countryside on the ground floor with a garden and an unruly dog, so that it will be quickly overwhelmed. And you also by the need to loosen the hair and change wipes which could be expensive in the long and not very environmentally friendly. In an apartment, if you are an avid tracker of dust, it will be helpful and you can take a break to do something other than the household. For a more intensive and practical use that exceeds the use "gadget", I think it is better to invest a substantial sum in a robot vacuum cleaner. Otherwise, Gus the dog had a great time at this track saucer that does not take off.
