2026 verdict
25000Pa and a 3-year warranty close the older dock: the Dreame L40 Ultra Gen 2 wins this robot vacuum comparison with a 231-minute battery and a larger water tank against the Roborock Qrevo Pro's 7000Pa and 180 minutes.
The Qrevo Pro is cheaper and holds a 330ml onboard bin versus 250ml, plus FlexiArm edge mopping that the L40 answers with an extendable side brush. Both map with LiDAR and self-empty with wash-and-dry docks. Choose the Dreame L40 Ultra Gen 2 for pickup and coverage terms; choose the Roborock Qrevo Pro when the lower price and larger onboard bin are the practical features.
