Today, they bring you a refurbished iRobot Roomba 4296 Remote Scheduler Robotic Vacuum for $99.99 + $5 shipping. It's list price is $329.99 and you'd have pay about 50% more for the same thing on Amazon.
One Amazon reviewer writes that "Roomba is perfect for our situation. We own 3 cats -- indoor/outdoor -- and before Roomba, we'd have to vacuum every day to pick up all the cat hair and dirt they drop or track in. We have all hardwood floors with a few throw rugs (some are taped down, some aren't, Roomba cleans them all no problem). Roomba handles floor-level changes like they aren't even there, cleans under the couch and tables and chairs, and so far has completely cleaned our floors without once scratching or marking our brand-new furniture. In the far corners there may be a few grains of dirt she couldn't reach, but overall we are ecstatically happy, and our hardwood gleams."
Sounds intriguing. I might have to pick up one of these myself.
