We moved into our home two years ago with two cats. We now have three. It's 1100 square feet (I think) and all wood floors. Which means for the first year and a half I swept almost every day. I kept little dust pans around the house and felt like it was a never ending process and it still never seemed clean. Hair was everywhere. So I decided to trade the cats for my Arte. Just kidding! We kept the cats and put this on our wedding registry. The cats even kind of like it and follow it around. I've never seen anything cooler than this - and I'm not a boring person! The box of collected hair/dirt is pretty big and if you use the robot on a regular basis you don't have to empty it with every use (though, I do). It can be programmed to start at a certain time daily but I just use it every few days. It does such a great job. It hops up onto thick carpets, has sensors to keep it from bumping into the pet water fountain (you shouldn't let it get wet), rubber edging, a tongue that comes out to get the corners clean!!, and if it gets caught on something it reverses and untangles itself. This is THE BEST GIFT IDEA for someone with pets, or an elderly person that has a hard time cleaning floors regularly. Honestly, it'd be good for anyone!
