We use it for half a year, it turned off a couple of times for unknown reasons :) it does an excellent job of cleaning fine animal hair, wet cleaning for 5, full-fledged mopping, of course, does not replace, but it is suitable for maintaining cleanliness. The light version does not "remember" the map of the house, it sticks into all the furniture and walls. But on the second lap he already overcomes obstacles. It would be great if there were two brushes for collecting small debris
