Bests & Worsts Reviews from Amazon

Updating: after a week of trying to find a manufacturer/seller to discuss repair/servicing, I have found zilch. The thing worked wonderfully--briefly. The one day in the middle of cleaning, stopped for no reason. Now will only back up an inch, then stop and beep an alarm. No troubleshooting in the manual made one bit of difference. Piece of absolute junk. Seems people are supposed to be willing to buy a new one once a month and be grateful. So, sadly, after loving "Crabby" for a time, I enter the ranks of crabby 1-star reviewers who found it mysteriously stopped functioning after a few weeks/months, and there is no company to turn to for repair. Don't waste your money. Buy a $3 broom from Dollar General. It'll last you 10 years. Adding to review below: the thing suddenly stopped working the other day. Nothing happened, it just stopped working. Troubleshooting with manual = an hour of totally wasted time. Cleaned everything. Unscrewed all the little screws and opened it up. Manual seems to indicate 2 beeps means "cliff sensors" need cleaning. Manual does not say what "cliff sensors" are anywhere, and also doesn't indicate whether one low beep, pause, 2 higher-pitched beeps means 3 beeps or 2 beeps. Not sure it's worth the cost of shipping this off, paying for repair, and paying for shipping back. So, it was fun for a brief time, but in the end a pricey and cheesy toy. Crabby does very well. And he looks like a crab too, with his little eyes and bristly claws. Very glad I decided on this low-end robot and not a more expensive one. This is all we need, no question. We have 2000 sq ft of all-wood floors on one story, so it's very easy. Have several cats and dogs, and this is perfect for the hair. Don't pay any attention to expensive product claims that this one won't pick up pet hair (from hard floors). I don't pick up the main household broom for days now, and we were sweeping several times a day before. Dogs went after it at first, of course, and border collie kept lunging out from behind furniture to bite it, but now they lazily shift out of the way when it approaches, and then lie back down again. One does have to go around the house picking up things that will get in the way, and I pull chairs out from the table so it can get around them (it does nicely go around furniture legs). Things it does not do: 1) kitty litter. We still have to use an actual broom around the cat boxes. Crabby will pick up some, but mostly the brushes scatter litter everywhere if it hits some. 2) corners, whether inside or outside. Its "edge" setting is great, but it goes wide around outside corners; and of course it can't really get all the way into inside corners. Other small things it can't handle: the kids' clothes on the floor--like the stray dirty sock lost under the bad. Small things will get partly sucked up and Crabby will choke and call for help. Pad that dogs' water bowls are on: gotta pick that up because, despite the half-inch-high edge, Crabby gets over it and spills the water, and then gets stuck and can't get back over the edge. And yeah, you can waste a surprising amount of time following it around with the remote, enjoying watching it eat up the balls of pet hair while you don't have to sweep--until you realize you could have swept half the da-n house in less time than you're spending steering this little guy. After a bit of fun the first few days, we've all learned to let it do its thing and not play with it. No idea how this would perform on carpet, as we have none, but for floors, it's perfect.
