Here is information I learned during my research but could not find in other reviews. Plus my verdict in a month. - It's worth the money (exceeds my value expectations) - It exceeds expectations (don't expect it to replace your housekeeper or thorough mopping once a week) - Most criticisms in critical reviews seem unfounded or misguided. - basic - it's pretty smart (doesn't clean the same area 5 times) - it does a damn decent cleaning - it won't go through thin carpets like carpet tiles - great battery life - I think it's worth getting a dedicated cleaning robot for around 2-in 1. I can't imagine a 2-in-1 doing this guy's job - It's quiet enough that you can watch TV/talk/have dinner while it cleans the same room (quieter than a robot vacuum) - three modes are useful, hope this helps!
