Don't get me wrong: I love me some robot vacuums but no matter which you pick, regular maintenance and babysitting is necessary. Even if a cleaning run goes off without a hitch and the botvac doesn't get stuck on a cord or trapped behind a door, you still have to clean carpet brushes and empty dust bins. Most botvacs have a dust bin capacity of around 0.5-0.7 liters. In my double-dog, double-kid house, I have to pause and empty the bin once or twice during every cleaning cycle. Otherwise, the suction tube gets clogged, or I can leave and walk back in my house to find the floors as dirty as when I left them.
