We have (2) English Shepherds and after about a month it was too much for this little machine. The little semi-sealed bearing at the end of the roller brush somehow still sucks up the hair and gets stuck. It's almost impossible to clean without destroying it. It wasn't listed as one of the cleaning items so I don't think they wanted it to be part of the routine cleaning. "Perfect for pet hair," the post says. Obviously, not all pet hair is the same. Otherwise it worked very well for its price. But without this camp, the rest is useless.
