If you made the resolution to tidy up more regularly in 2022, a robot vacuum can help with that. And for those that hate cleaning, investing in a robot vacuum with self-emptying functionality can make it so you rarely have to interact with the machine. Two of iRobot's higher-end models with clean bases are on sale at Wellbots right now when you use the code ENGADGET250 at checkout -- both the Roomba s9 and the Roomba j7 will be $250 off, bringing them down to $850 and $600, respectively. Those are great deals, especially considering the prices are better than we saw during Cyber Monday at the end of last year. The Roomba j7 is the latest robo-vac from iRobot and it has new AI-driven computer vision technology the helps it detect objects and move around them as it cleans.
