Anker's Eufy 3-in-1 E20 robot vacuum is $150 off right now, as part of Amazon’s Big Spring Sale. That brings the price down to $450, which is a record low. For those averse to using Amazon, the deal is also available directly from the company.

Eufy features the cheapest handheld and robot vacuum combination this year, with a handheld unit built into the robot's body instead of the dock - and it's on sale.

Right now, the Eufy Robot Vacuum and Mop Combo Omni C20 has just dropped to $399 on Amazon from $699. That’s an incredible discount of $200, saving you serious cash for a top-notch robot vac.
