The dust cup is very difficult to clean out. You have to use a piece of paper or flat object to get the hair and particles free from the sides of the motor/inlet. I also don't like the idea of it sitting on my counter. I would rather have it on the wall. It doesn't last nearly as long as advertised on a full charge on regular setting. Other than those three items, it has really good suction. I like the slim shape, too.
