Customer service is terrible. The vacuum is ok. It cleans but doesn’t pick everything up. I’ve found clumps of dog hair it seemed to push together but not suck up. The tangle free brush does get tangled but not as bad as the roombas do. Our power went out a few days ago and it lost connection to the WiFi. I followed the instructions to connect it back and it wouldnt work. I ended up selecting add another robot and I was able to get it back online. I recommend spending a little more and getting the iRobot.
