Got this a couple of months ago for my lab & 2 cats that shed everywhere. It's a miracle for keeping pet hair off the floor, but the app only works 1/3 of the time. When working, you can choose spots or rooms which is amazing. But the app doesn't finish loading most of the time, making it totally useless because you can't even start the vacuum. Suction is great on max however I had to buy a rubber bumper because it wrecked my antique living room furniture (wife is mad). I've always been shark loyal and have owned a few shark vacuums over the years and trust their product quality. PLEASE FIX THE APP PLEASE! I didn't pay this much money for a vacuum that doesn't do what I payed for it to do! I literally can only vacuum the entire house from pressing manual button on vacuum. I will return if this can't be fixed soon. Simply not worth it without the app.
