It’s spring cleaning season, but that doesn’t mean you need to get on the floor and scrub. Robot vacuums are a great way to keep your home clean while doing little to nothing, and a few robovacs from Shark are currently on sale. One of the best deals comes courtesy of a 44 percent discount on Shark’s AI Robot Vacuum and Mop. The device is down to $270 from $480 — only $20 more than its all-time low price.
