Shark's new 2-in-1 robot vacuum and mop is cheaper than it's ever been

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.
