SAVE 390: As of April 29, the Dreame L10s Ultra Robot Vacuum and Mop Combo is on sale for 399 at Amazon (for Prime members). We love a good robot vacuum deal here at Mashable. You could even say we're obsessed. But who can blame us? What's better than something that removes the need to manually vacuum, and better yet, mop?
