I'm giving this 5 stars. I have two cats and a dog. I'm 79. I haven't the energy to run the vacuum cleaner daily, even though I've got an excellent Seba. I can't afford to hire a cleaner oftener than once a month. So I thought I'd give the Arte a try, even though I was doubtful. So doubtful that I let it sit for a month in its shipping box before I finally got it out, studied the manual, and gave it a try. I am amazed! At first, I ran it every day, then every other day, now every 2-3 days. At first the dirt container was packed full with all manner of dirt. But now there's very little. This Arte has really cleaned my rug thoroughly, all 5 rooms plus the bathroom (and the carpetted deck when I let it). I feel much more comfortable walking around my apartment. (I now take off my shoes as soon as I bring the dog in from his walk, and walk around in socks or slippers, so as not to track in dirt and leaves from outside.) I would give the Arte 5 stars but for the nuisance of having to clean the brushes every time; they collect lots of tangled dog and cat hair as well as acrylic carpet fluff (the worst!). It takes me a good 10-15 minutes to clean them thoroughly. I'm afraid I'm damaging the brushes and wonder how long before I'll need to replace them. By the way, I wash the dirt container and the filter (but not the brushes) under the kitchen tap, and let it air dry before putting it back in the machine. Anyone know if that's harmful? Oh, another nuisance although unavoidable: picking up all the pet toys and electric cords lying on the carpet, then putting them back afterwards. One final thing: Arte does its work so cheerfully, never complains, doesn't mind being told to go back over an area again, and I am grateful for the Sound noise that tell me what's wrong when the Arte suddenly stops, because it's trapped somewhere and can't get out, or its brushes need cleaning, or whatever.
