I was sitting on the couch watching my XV-12 do its Monday cleaning when I first saw today's Woot. Same price I paid on Home Woot just 2 weeks ago, but that's okay. I've added the pet upgrade kit to my Amazon wishlist and will try it sometime.
In the meantime, I'm loving this thing. I ran it as soon as it was ready to go. We live in a modest 2 bed/2 bath duplex and I had to empty a full dirt bin 3 times! It got stuck once under a bed on some thick foam-like clumps that my cat keeps digging out of the box spring, so I don't blame Neato for that. We just threw it all away and will keep the cat from doing it anymore. It also got itself wedged between the toilet and bathtub, so we'll either just keep that bathroom closed or it could be solved by putting a trash can or basket on that side of the toilet.
It also seemed to get confused by a bedroom door that it could push about an inch or two, but the door would come back, so it felt like it was an obstacle I guess? Solved that by putting a small heavy object in front of the door to prop it all the way open/against the wall.
Has had no problems returning to its base. We have it on a Monday and Friday schedule. It does a little more than half of the house before returning to charge. After just cleaning on Friday, it did its first half just now, is recharging, and already had a full dirt bin. So it really does its job (or we're pretty disgusting people, I'm not sure which :D )
It also picked up like a half a pound of my fiancee's hair, most of which got wrapped around the roller, which I had to cut out with a knife. But I'm hoping after a week or so, that'll be less of a problem as it begins doing so regularly. We really put it through its paces in that first week since we don't vacuum much.
This is why this product is great for people like us. We'll say we need to vacuum more, but we end up putting it off to where we're really only doing it like once a month, or before people are coming over. This way, it's just done, twice a week, way more than we ever would do it ourselves. And I'm also hoping it cuts down on the dust that ends up sitting around on furniture. Yes, we have to keep cat toys and shoes off the floor, but that's just a bonus in that it helps you keep your place looking tidier.
Very happy so far.
