Amazon Spring Sale robot vacuum deals: The best sales from Shark, iRobot, Dyson, Anker and others

We've now hit the third day in Amazon's Big Spring Sale and, like last year, it seems to focus less on tech deals and more on home, cleaning and fashion discounts. We've tested dozens of these handy automatic floor cleaners and put the results in a couple of our buying guides. Most of the deals that debuted when the sale kicked off are still live. Well, really, many of these deals went live before the sale's official start date this Tuesday. But they may not stick around long after the sale is done on Monday, March 31. As it stands now, a number of our recommended robot and cordless vacuums are on sale and we've rounded up the best deals we could find, right here.
