I have a Roomba and a Braava and it has changed my life!! Both are well worth the cost for the convenience and peace of mind it gives me. With a busy household these little darlings make life more enjoyable. Who ever thought cleaning could be so much fun! I use the Brava on hard wood, and tile, in small rooms and large, and in high traffic areas. For daily maintenance it works like a charm. The only con I can find to this little beauty is it does not have virtual walls like the Roomba. With an open floor plan, I have to block off areas to keep it contained. Also don't like that it can fall down stairs, so I have to babysit it when I am using it in certain areas around the house. Overall, this one's a no-brainer if you are looking to spend less time cleaning. Don't be intimidated, just make the investment. Watch the dvd's so you get the most out of your irobot and join the revolution!
