Shark's self-emptying robot vacuum is nearly half off today

Robot vacuums can be expensive, and if you want one with a base that automatically collects dirt, it'll cost you even more. But now you can get one of Shark's most advanced models for the lowest price we've seen. The Shark IQ RV1001AE robot vacuum with clean base is 47 percent off, bringing it down to $319. That's more than $280 off its normal price and the lowest we've seen it -- not to mention that also makes it even cheaper than most iRobot devices that come with clean bases, even when they've been on sale. We've been fans of Shark's robot vacuums since one of its cheaper models made it into our budget robot vacuum guide.
