iRobot Roomba 510 Vacuum Cleaning Robot $159.99

Here's a bit of a niche item, but if you happen to be on the lookout for one of these, it's nice to find it at a better price. Buy.com is offering the iRobot Roomba 510 Vacuum for $159.99, which is way below list price and $90 less than Amazon at the moment.

This is the kind of vacuum that you set up to run on its own so it can take care of a household chore while you're busy doing other things (or not). It can clean three rooms on a single charge, gets into hard-to-reach areas like wall edges and beneath furniture while avoiding stairs and other drop-offs.

The Roomba automatically adjusts from carpets to hard floors and back again. Virtual Wall tells it where to clean by restricting off-limit areas. It detects dirtier areas and spends more time cleaning them, and Spot Clean provides quick clean-up of spills and concentrated messes.

The unit seems to get good reviews, so if you want to check it out and maybe take advantage of the sale, click on the picture below.
