The Dreame D30 Ultra CE leans on smarter navigation, using 3D structured light obstacle avoidance to steer around cords, socks, and pet messes that the Mova P20 Ultra will simply drive over. The Mova counters with stronger hardware: 30,000 Pa of suction, an anti-tangle brush, 12 N of mop pressure, and a dock that washes pads with hot water at 167 °F. Pick the Dreame for cluttered floors and hands-off reliability, the Mova for deeper scrubbing and pet hair that wraps around brushrolls.
Same mop hardware, very different philosophies. Both of these robots use dual spinning mop pads, LiDAR navigation, rubber main brushes, and auto-emptying docks, so the decision comes down to whether you'd rather have a robot that avoids trouble or one that cleans harder once it gets there. The Dreame D30 Ultra CE spots obstacles with 3D structured light and covers 1,679 sq ft on a single 230-minute charge. The Mova P20 Ultra skips obstacle detection entirely but brings more suction, double the mop pressure, an anti-tangle brush, and hot water mop washing. Two reasonable answers to the same problem.
Dreame D30 Ultra CE
out of 10Mova P20 Ultra
These two land close together overall, 6.9 for the Dreame against 6.6 for the Mova, so neither runs away with it. The clearest split is navigation, where the D30 Ultra CE earns a 7.0 next to the P20 Ultra's 5.6, and that gap traces directly to obstacle avoidance. Flip it around for cleaning, 7.1 versus 7.3, and features, 5.9 versus 6.3, both narrow wins for the Mova. Preference decides this one.
Obstacle avoidance is the dividing line. The Dreame uses 3D structured light to identify and steer around clutter mid-run, and the Mova has no equivalent system, meaning it relies on LiDAR mapping and bumpers alone. On the cleaning side the Mova pulls ahead with 30,000 Pa versus 25,000 Pa and, more importantly, an anti-tangle brush design the Dreame lacks. Mopping tilts Mova's way too: 12 N of downward pressure against 6 N, spinning pads turning at 260 RPM versus 160 RPM, adjustable water levels, and a dock that washes pads at 167 °F and dries them at 145 °F. Battery goes the other way, with the Dreame rated for 230 minutes and 1,679 sq ft per run.
The Mova P20 Ultra brings 30,000 Pa against the Dreame's 25,000 Pa, but the bigger deal is its anti-tangle brush, which keeps long hair from wrapping around the roller. Both use a single rubber main brush, so the difference comes down to that tangle-resistant design and the extra suction.
Both robots use dual spinning mop pads, the stronger of the common mopping designs, but the Mova pushes down with 12 N versus 6 N and spins at 260 RPM versus 160 RPM, which means real scrubbing on dried spills. Adjustable moisture levels also let you dial water down for sealed wood and up for tile.
If you've got a shedding dog, the Mova's anti-tangle brush saves you from cutting hair off the roller with scissors every couple of weeks. Its 30,000 Pa also pulls embedded hair from rug fibers a bit more aggressively than the Dreame's 25,000 Pa.
This is the Dreame's clearest advantage. Its 3D structured light system actively identifies obstacles like charging cables and shoes and routes around them, and the Mova P20 Ultra has no smart obstacle avoidance, so it depends purely on LiDAR mapping and physical contact.
The Mova's dock washes mop pads at 167 °F and dries them at 145 °F, which does a better job breaking down grease and keeping pads from smelling musty. It also holds slightly more in both the clean and dirty water tanks.
The Dreame D30 Ultra CE runs up to 230 minutes and covers 1,679 sq ft in a single outing, which handles most single-floor homes without a mid-job recharge. That's useful if you'd rather set a schedule and never think about it.
Both support no-go zones, multi-level maps, and smart carpet cleaning, so the split comes from the Dreame's voice control through Google and Siri plus its smart obstacle avoidance. That combination makes it the more connected of the two.

Pick the Dreame if your home has obstacles the robot needs to dodge and you want voice control plus long runtime. Pick the Mova if your priority is deeper scrubbing, stronger suction, and a brush that shrugs off hair. Both handle the fundamentals well, so match the strengths to your floors.
