i debated on this forever and did a ton of research. i looked at many "top robot vaccum" articles and this one was not on any of the rankings. joke is on whoever wrote those articles, this robot vaccum is far more superior than any other vaccum. we have two thick rugs in our house that are on hard floor. the vaccum has no problem climbing onto the rugs and does not get stuck at all. i was super impressed by how quickly the vaccum was able to map our house. honestly, if you're thinking about it, get it. you seriously will be so glad you did.
