Anker's Eufy 3-in-1 E20 robot vacuum is 150 off during the Amazon Big Spring Sale

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. The E20 made our list of the best robot vacuums, and with good reason. We loved the hybrid functionality, as this robovac quickly transforms into a cordless stick vacuum and a handheld unit.
