Let me start by saying this thing is a lifesaver. I'm not sure why it took me so long to buy something like this as it has greatly reduced the daily arguments in my house. I'm a full-time working mom and I love the feeling of walking into my home with a clean floor free of my kids' crumbs. I set a timer to use the remote while I'm at work. On the weekends I see this thing in action and it does a great job avoiding walls and corner kinks. He's already learned how to move around my house properly. Just a tip: remember to close your bedroom doors. One day I accidentally left mine open and the vacuum cleaner picked up a phone charger and headphones that my kid had left on the carpet and I had to throw them out as they deformed the wiring. It is a powerful and efficient device with great suction power. If that thing breaks, I'll invest in a canister vacuum.
