Our take on the Dreame L40s Ultra AE Robot Vacuum

The Dreame L40s Ultra AE is a self-emptying, self-washing robot vacuum and mop with 19,000Pa Vormax suction, a liftable rubber brush, and a MopExtend arm that swings the mop under low furniture. Its PowerDock washes pads in 167°F water, dries them with hot air, and holds dust in a 3.2L bag for up to 100 days. The 5,200mAh battery is rated for up to 180 minutes and about 1,808 sq ft per charge. At $398.87 at eBay as of November 3, 2026, it sits well below its recent daily range of $541.49 to $569.99.
