The Roomba j7 vacuum hits new all-time low in iRobot's Cyber Monday sale

The holiday shopping season is one of the best times of year to look for a new vacuum -- robotic or not. We've seen numerous models go on sale before and during Black Friday, and now a new Cyber Monday sale has knocked iRobot devices down to new record lows. Key among them are the new poop-detecting j7 duo of robot vacuums, both of which are $200 off. The Roomba j7 has dropped to $449 while the j7, which comes with a clean base, is down to $649. Those prices are being matched at Best Buy and Wellbots, too.
