My wife and I and our 3 fur babies(cats) live in a decent size townhouse and we love our Roomba s9+ with self cleaning dock! Our first robot vacuum purchase and it delivered! We're really impressed how this robot vacuum picks up our cats dander and their litter tracks. Worth the money totally! Actually we own the i3+ with dock as well and it's stationed in our bedroom to clean the upstairs rooms. Our Dyson V11 animal is on standby at this point.
