Dreame D30 Ultra vs Roborock Qrevo QV 35A

25,000 Pa against 8,000 Pa is not a close race, and that suction gap anchors why Dreame D30 Ultra wins this robot vacuum comparison against Roborock Qrevo QV 35A, also taking price, warranty, battery life, water tank capacity and dock dustbin capacity. Roborock Qrevo QV 35A answers with a bigger onboard dustbin, the one column where it comes out ahead. Both machines vacuum and mop with self-washing, self-drying docks, and neither supports Apple Home or Matter, so the practical differences come down to raw cleaning power and running costs rather than ecosystem reach. Owners of the Qrevo QV 35A do note refilling its water tank more often than advertised, a problem the D30 Ultra's larger tank should reduce. For buyers who want the strongest suction and lowest price, Dreame D30 Ultra is the clear pick; only a bigger onboard bin would tip it toward the Roborock.
