Seriously, if you hate vacuuming, you should consider buying one of these things. We got one for my parents' place recently and it worked so well that I went out to buy my own after borrowing it and trying it at my house.
You'll be stunned at the amount of sh*t the thing picks up when you go to empty it after it's done vacuuming. It even has a charging dock which it automatically returns to at the end of its vacuuming cycle to recharge its battery. It has sensors to ensure that it won't fall down stairs and will generally work its way around the edge of a room with a little brush which knocks crap out of the corners so it can be vacuumed up.
I love the damn thing. I leave for work in the morning, hit the button to tell it to clean and I'll find it sitting in its dock when I get home with a full load of hair, sand and crap which I didn't even know was on the floor. It even cleans the shag carpet in my room.
The only catch is that you need to pick up and remove things which you wouldn't be able to get with a regular vacuum, which makes it not really a catch at all considering that you'd have to do that anyway if you wanted to vacuum the floor.
There's a special deal at Bed Bath and Beyond right now with a 20% coupon which they've been mailing to people. If you call them, they'll send you a coupon which takes the price of the robot from $279 to $223. It seems pricey, but a decent vacuum goes anywhere from $150-400 and rather than buy one which I need to push around, I'd rather buy one that'll do the work without me.
The best part is that my roommate's GF wants to bitch at me for not cleaning but she can't do that since I paid for a device to do it for me.
