re: iRobot Roomba 980

I have the 960 and it’s a game changer especially if you have pet hair. Mine has never gotten stuck under the sofa and one of the main reasons I love it is because it cleans under the furniture where pet hair and dust gathers. It goes under the tables and around the legs of each chair, really is incredible. It does skip small sections sometimes like others have said, but then hits those sections other times. It does like to go over areas it's already done and it wanders from room to room back and forth. My downstairs is about 2600 s/f approx and it takes about 2.5-3 hours to finish. That is kind of aggravating although it's very quiet. If you have pet hair you'll have to empty the bin each time but it's very easy to do. We haven't used the regular vac since we got the 960. I was reluctant to spend the $ but it's well worth it imo.

ps - I was warned not to use it if you have pets and you're not home (unless they're kenneled I guess). I heard a story of a dog that shite the floor and the roomba went back and forth through the shite tracking it all over the entire house and rubbing shite on the edge of walls and furniture...
