This robot vacuum is great for cleaning and collecting pet hair. The only problem is that longer pet hair can and will get tangled/tangled in the roller brush. But the included full-length hair clipper makes hair removal super quick and easy. The dust container in a vacuum can also fill up fairly quickly, but unless you have a lot of pet hair to pick up, it can usually empty an entire medium-sized room before it needs to be cleaned. For larger rooms, you may need to empty it once or twice so it doesn't affect suction too much.
