Suction is the headline split here: the Mova E40 Ultra pulls 19,000 Pa with a rubber-and-bristle brush that has a built-in hair cutter, and it runs for 260 minutes per charge. The Roborock QV 35A trades that pulling power for smarter obstacle handling, using 3D structured light on top of LiDAR plus 30 water flow levels for finer mopping control. Homes with pets and carpet lean Mova; cluttered floors and multi-level layouts lean Roborock.
Both of these robots check the same big boxes on paper. Dual spinning mop pads, LiDAR mapping, auto dust emptying, mop self-washing, no-go zones, multi-level maps. So the decision comes down to what each brand chose to spend its engineering on. Mova poured it into suction and endurance, giving the E40 Ultra more than double the airflow rating and a longer runtime. Roborock spent it on perception and mopping precision, adding 3D structured light for obstacle detection and a much finer water flow scale. Two very different answers to the same question about what makes a robot vacuum feel reliable day to day.

These two land almost on top of each other overall, 6.5 for the Mova versus 6.6 for the Roborock, so neither one runs away with it. The Mova takes cleaning 7.3 versus 6.6, thanks to that big suction number and the brush design. Roborock flips it on navigation, 7.0 versus 5.6, because of the added structured light sensing. Features are basically even at 6.2 versus 6.1. Both sit at fair prices for what they do.
Airflow is the first thing you'll notice on the spec sheet: 19,000 Pa on the Mova against 8,000 Pa on the Roborock, and the Mova pairs it with a rubber-and-bristle brush that includes a cutter for tangled hair. Runtime favors Mova too, 260 minutes versus 180. Roborock counters on how it sees the world, adding 3D structured light to its LiDAR rather than relying on LiDAR alone, and it handles up to four saved floor maps. Mopping control tilts Roborock's way as well, with 30 water flow settings versus three and a documented 200 RPM spin on the pads. The Mova also brings an extendable mop arm for edges and a three-year warranty against Roborock's one year.
19,000 Pa versus 8,000 Pa is a real gap, and the Mova backs it with a hybrid rubber-and-bristle brush that includes a hair cutter to stop wrap-around. The Roborock's all-rubber brush resists tangles well and its dust box is slightly larger, but on carpet the Mova pulls harder.
Both use dual spinning mop pads, the strongest widely available mopping setup, so the core scrubbing action is comparable. Roborock offers finer tuning with 30 water flow levels and 200 RPM pads, and the Mova answers with an extendable mop arm for baseboards plus a slightly higher mop lift of 10.5 mm.
For shedding dogs and cats, the Mova is the stronger pick: more suction, a brush with an anti-tangle cutter, and a 3.2 L dock bag versus 2.7 L means fewer bag changes between vacuuming sessions.
Both map with LiDAR, but the Roborock layers on 3D structured light to spot socks, cords and pet bowls, which the Mova handles with LiDAR alone. Roborock also stores up to four floor maps, making it the better fit for taller houses.
The Mova's dock is the roomier one across the board: a larger dust bag, a larger clean water tank and a larger dirty water tank, which stretches the time between refills and dumps. Both docks empty the bin and wash the mop pads on their own.
The Mova runs longer per charge at 260 minutes versus 180, so it needs fewer recharge breaks on a big job. Roborock lists 1,536 sq ft of coverage in a single run, a clear number to check against your floor plan.
This one is a genuine tie. Both work with Amazon Alexa, Google Assistant and Apple voice control, and both include no-go zones, multi-level maps, smart carpet cleaning and smart obstacle avoidance.

There's no wrong answer here, just two different priorities. Go Mova if dirt pickup, runtime and dock capacity top your list. Go Roborock if you want the robot to see obstacles more clearly and manage more floors. Both self-empty, both self-wash, both use dual spinning mops.
