The Roomba 850 Robotic Vacuum is iRobot’s hottest new robotic vacuum cleaner. And just like most other Roomba models, it’s very expensive. You get what you pay for with Roombas, of course, but the $440 retail price is a difficult pill to swallow when there are so many great rival vacuums out there for much less money… most of the time. Today, however, that’s not the case at all. Amazon has a killer one-day sale going on the new Roomba 850 that slashes the price to just $289.99. It’s the first big discount on this great new Roomba model, and we doubt we’ll see it priced this low again until Black Friday at the soonest.

Here are some key details from the product page:
