I was so excited when I saw this in the Revain Lightning Sale. We have a simple floor - wood and tiles. Pros: 1) He collected a lot of dirt. BUT. 2) it has quite a few CONS: 1) it has NEVER been able to go back to its base to charge - tried 10 times 2) got stuck on cords and stuff 3) ate the cord and nearly started a fire 4) it goes in high performance mode when it hit the table chairs and pushed my wooden kitchen chair into the wall leaving a scratch 5) the instructions have a NULL value 6) the software app is pretty much useless - no help 7) the interface with Alexa is terrible
