iRobot Roomba 3000 Robotic Cleaner

I have two large dogs with coarse hair that tends to stick in the carpet, so this was a real challenge for my new Roomba! I was quite impressed. Roomba picked up around 75% of the hair on it's first use. It does seem to go in a very random pattern, going over the same area time and time again, but it eventually covers the whole area. My front room, 12ft x 12ft, took 45 minutes for Roomba to clean before it turned itself off. It is a bit of a pain to clean the brush, which must be done after every use, otherwise it doesn't clean as efficiently. The little collecting tray fills up fast, but just takes 2 seconds to empty. I don't think the brush will have a long life span, but they are replaceable, though expensive. The Roomba is OK for in between 'proper' cleans with a normal vacuum cleaner, but it could never replace one. On the plus side, it's excellent for picking up dry spills, such as breakfast cereal, when set on to 'spot' clean. I would recommend the Roomba for light cleaning in a household that doesn't get too dirty!
