Ok, so I went and bought a refurbished one on ebay, lol. It was a lot cheaper than the brand new ones, but it is working just fine and came with a bunch of things (virtual walls, remote scheduler too). I've used it twice now since it got here, and it REALLY cleans! I have only used it on the first floor living room, where it's hardwood and one large area rug, but wow! It went under all the sofas, the entertainment center, everything. It really got a ton of litter, cat hair and everything! I'm really impressed! I love how it docks itself, and the cute noises it makes when doing that or if it gets stuck (I have old electrical outlet holes in the floor that the previous owner took out, so it's just the metal housing that you could put the outlets into... apparently floor outlets are not up to code or allowed anymore). That's the only place it's gotten stuck, because it's wheel got into it and couldn't get back out.

Not sure if I'd use it on the 2nd floor, where it's all carpeted. I'd probably kill it with all the cat hair up there! Plus, I still love to vacuum! Now, if they invented a robot vacuum cleaner that cleaned sofas and chairs all by themselves, I'd buy that sucker in a heartbeat!!
