I've always had to vacuum frequently because my cat and my husband both shed, and our laminate floors show it all, unfortunately. With the addition of our dog--who also sheds profusely--a few months ago, I can't keep up with the hair anymore. So I'm considering splurging on a Roomba. I've checked them out online, and I'm definitely leaning toward the cheaper ones. I wanted to see if anyone here has one, and if so, do you like it? Can it keep up with pet hair? Is there a big difference in how well the cheapest one works vs. the ones that are a step or two up? I'm figuring we'll still have to vacuum, but I'm tired of vacuuming on Sunday only to have the floor so furry by Monday night that you wouldn't know I'd done anything, so if the Roomba can help keep the fur down it might be worth it.
