The robot is in use at our house and we have a bitch who is currently losing a lot of hair. It is worth mentioning that we only use the robot on parcels and not on carpets.
It does a great job on the carpet and picks up almost everything! The hairs are pulled into the container and only a few get caught on the brush. Emptying is also extremely easy and the dirt comes out as a whole "square" lump haha.
We are very happy with it.
Hope this is helpful.
