Bought this few weeks ago and has been the best purchase yet. We have a German shepherd and fur is all over every day. Thanks to  this lil guy he keeps up with the tumble weeds the dog creates. We also have bar stools with legs that connect to each other with a 1/4” bar across the floor, good’ol robot kicks it in 4 wheel drive somehow and has no issues jumping the bars. As for our running carpets it’s no challenge to the robot, smooth transition from tile to running carpet and back to tile. They say it has a 45 day or so to empty the bin but since we have a lot of fur we empty it every time it completes its run. The only down side of the whole robot is the filter. Wish it could be removed and washed out but it looks like you have to replace the whole plastic piece when it is time to change the robot filter, the one in the tank looks to be easily washed and replaced. Besides that I’d definitely recommend this lil guy.
