If you've been putting off any spring cleaning -- who hasn't? Robot vacuums have been popping up everywhere and, though they can be pricier than a do-it-yourself option, the Shark AI Ultra 2-in-1 robot vacuum is currently making a play for your home with a 43 percent off sale. It's still not an impulse buy in the check out lane, but, at $400 versus $700, it's the best deal we've seen since it launched. This 2-in-1 model uses smart home mapping to clean in a precise grid, empties itself and has improved suction power. Shark also claims the mops can scrub floors 100 times per minute.

In addition to launching the 12T smartphone series today, Xiaomi also announced that its Robot Vacuum X10 -- which debuted in China back in April -- is now headed to Europe. This is the company's most versatile robot vacuum to date: Not only can it vacuum with 4,000Pa suction and mop with pressurized dual rotating pads, but with its base station, it can automatically empty its trash, refill its water tank, wash its mops and dry them with heat as well. All told, the robot vacuum itself should require little maintenance; you'll just need to refill the base station's water reservoir and empty its waste water tank and dust bin from time to time. This isn't the first time Xiaomi released a robot vacuum with both mop-cleaning and mop-drying features; it did so for the Chinese market almost a year ago. With other models, you'd have to detach and wash the mop yourself which, let's be honest, isn't the most pleasant job in the world.
