After a few times I gave the use NaviBot my young nephew, has the joy of technical bells and whistles. The thing is already working as described - but it's the way that you have to do as freely as possible prior to use the floor (put chairs on the table, roll up carpets, floor lamp lay on the couch, then set trash cans, etc. etc.) After sucking the corners and edges are clean never really right; the "margins" program I have unfortunately not set in motion - which means you have anyway NACHputzen somehow. Then shut put all that stuff back ....... That's a total of more effort than if you take the same a "normal" vacuum cleaner and quickly sweeps through the apartment. The product is not bad but not really timesaving.
