iRobot's high-end Roomba i7 and S9 are up to $150 off at Wellbots

We all could use a little help keeping our homes clean and a robot vacuum can do just that. Some robots, like iRobot's Roomba i7 and S9, go one step further by automatically emptying their bins into their clean bases after each job -- so you rarely have to take out its trash. These gadgets come with high price tags, but you can grab either of them for less right now at Wellbots. The online retailer has the Roomba i7 for $699, or $100 off, and the S9 for $949, or $150 off, when you use the codes 100ENGADGET and 150ENGADGET, respectively, at checkout. While not all-time-low prices, they're the best prices we've seen since April.
