My friend has used a Roomba in her home, with both cats and dogs in her house. She runs hers several times a week, especially when they are shedding, and also uses her regular vacuum at least once a week. And, she just ordered a new Roomba today. She added that her Roomba does require regular maintenance on the rollers to remove hair and fur -- and she does that task at least once a month on both the Roomba and her regular vac. Hope this helps!
