actually it was meant more as a joke for my wife, but that the thing works so well both surprised us. He now runs as a little friend of the family through the house and makes really clean. The hopper is with us always fill up fast and we do not have to collect more balls of wool from our dog. He has indeed barked at him 1 week but mittleiweile he looks at him calmly. Nice useful item! We no longer want to be without him. If he then autonomously parked on the charging station, we often think ... ok he has earned :-))
