Q: Is this vacuum cleaner good for pets like dogs and cats

A: I have had my vacuum for nearly one month. We have a medium haired black cat and I vacuum up a lot of hair off of the rugs and floor. It picks the hair up very well - mine included. I first cleaned the dock at about 3 weeks, as we live in the country and our cat is indoor-outdoor. Also, my husband doesn't take his shoes off after out cutting wood, etc, so I usually vacuum once a day. I am very satisfied with this vacuum.
