Navigation is the dividing line here. The DEEBOT X9 Pro Omni pairs LiDAR with a camera, a light, and 3D structured light AI obstacle avoidance, plus a roller mop and automatic detergent dosing, which suits cluttered homes with pets, cords, and toys on the floor. The Mova P20 Ultra counters with 30,000 Pa of suction, dual spinning mop pads pressing down at 12 N, and bigger dock tanks, making it the pick for someone who wants scrubbing muscle and longer stretches between refills.
One of these robots is built to see and think its way around your floors. The other is built to power through them. Ecovacs leans into sensing hardware on the X9 Pro Omni, with a camera, a light for dark rooms, and 3D structured light feeding an AI obstacle system, then finishes the job with a roller mop and detergent dosed straight from the dock. Mova takes a more mechanical approach on the P20 Ultra: 30,000 Pa of suction, dual spinning pads with real downward pressure, and a dock with larger water reservoirs. So the decision comes down to whether you value smarter movement or stronger scrubbing.
Ecovacs DEEBOT X9 Pro Omni
out of 10Mova P20 Ultra
The gap is wide. Overall, the X9 Pro Omni earns an 8.4 rating against 6.6 for the P20 Ultra. Cleaning sits at 9.2 versus 7.3, which shows that suction numbers alone don't decide real-world results. Navigation is the biggest split, 7.7 versus 5.6, and that tracks with the Ecovacs having a camera, a light, and AI obstacle avoidance the Mova doesn't. Features land closer together at 7 versus 6.3. On value, the X9 Pro Omni does more than its price would predict, and the P20 Ultra is priced about right.
Start with obstacle handling. The X9 Pro Omni uses AI plus camera plus 3D structured light to spot and steer around things like a charging cable or a dog bowl, and it has a light so it works in dim rooms. The P20 Ultra relies on LiDAR mapping alone for that job. Suction flips the other way, 30,000 Pa for the Mova against 16,600 Pa for the Ecovacs, though the X9 adds a rubber brush with a built-in hair cutter and a liftable main brush. Mopping styles differ too: a roller on the Ecovacs versus dual spinning pads at 260 RPM and 12 N of pressure on the Mova. And the Ecovacs dock adds detergent when it washes, while Mova's dock uses water only but holds more of it.
On paper the P20 Ultra wins with 30,000 Pa against 16,600 Pa, along with a bigger onboard dust box. But the X9 Pro Omni's rubber brush includes a hair-cutting element, and its higher cleaning rating shows suction isn't the whole story.
The Mova's dual spinning pads scrub at 260 RPM with 12 N of pressure, which is the stronger setup for dried-on messes. The Ecovacs roller mop is newer tech that self-rinses as it works, spinning at 220 RPM with 50 moisture levels and a mop lift of 10 mm for carpets.
Heavy shedders benefit from the Mova's 30,000 Pa and slightly larger 3.2 L dust bag. The Ecovacs answers with smart dirt detection that ramps up on messy spots and a brush cutter designed to slice through wrapped hair.
This is the Ecovacs' strongest area: LiDAR plus a camera, a light, and 3D structured light AI obstacle avoidance that steers around socks and cords. The Mova maps well with LiDAR and handles up to 4 floor levels versus 2, but it lacks the obstacle-avoidance sensing.
Both docks empty the dustbin and wash the pads automatically, so it's a trade. Mova's dock holds more clean and dirty water for longer gaps between refills, and the Ecovacs adds detergent during washing for cleaner pads.
The X9 Pro Omni runs up to 252 minutes on a 6,400 mAh battery, which covers large homes in fewer charge breaks. The P20 Ultra's 5,200 mAh cell is the smaller of the two.
Both offer no-go zones, multi-level maps, and smart carpet cleaning. The Ecovacs adds voice control through built-in commands, Alexa, and Google, plus smart dirt detection and smart obstacle avoidance, giving it the deeper app and voice toolkit.

Cluttered, multi-room homes where a robot needs to think on its feet favor the DEEBOT X9 Pro Omni, and its longer runtime and voice control back that up. Pick the Mova P20 Ultra if scrubbing power and a dock you rarely need to touch matter more than clever obstacle dodging.
