Suction is where these two split apart: the Mova P50 Ultra pulls 19,000 Pa against the Dreame X40 Ultra's 12,000 Pa, and it pairs that with slightly richer obstacle detection thanks to an added LED for low-light rooms. The Dreame counters with a bigger 6,400 mAh battery, a liftable main brush, mop pads that detach automatically before carpet runs, and heated air drying in the dock. Buyers with pets and lots of carpet lean Mova; buyers with large hard-floor homes and a mix of surfaces get more out of the Dreame's automation.
Dreame builds the X40 Ultra, and Dreame's sub-brand Mova builds the P50 Ultra, which makes this less a brand rivalry and more a question of where the engineering effort went. The P50 Ultra chases outright suction and sharper obstacle detection. The X40 Ultra spends its budget on automation: a brush that lifts, mop pads that release on their own, and a dock that dries them with warm air. Both run LiDAR, both use dual spinning mop pads, both empty their own dustbins. So the decision comes down to whether you want more pulling power or more hands-off convenience.
Dreame X40 Ultra
out of 10Mova P50 Ultra
The Mova P50 Ultra takes the overall rating at 9.1 to 8.5, and the gap traces back to two categories. Cleaning sits at 7.8 versus 7.0, driven mostly by that 19,000 Pa suction figure. Navigation lands 9.0 versus 8.1, helped by the extra LED in the obstacle detection stack. Everything else is a dead heat: both earn 9.5 for features and 9.4 for value, which tells you the automation packages are equally deep.
Suction sets the tone. The P50 Ultra's 19,000 Pa is a substantial step up from the X40 Ultra's 12,000 Pa, and that shows up in embedded pet hair and carpet debris. Battery flips the other way, with the X40 Ultra carrying 6,400 mAh against 5,200 mAh, so it covers more ground before heading back to charge. Then there's the automation gap. The X40 Ultra lifts its main brush to protect mop runs, detaches its mop pads automatically before it drives onto carpet, and dries those pads with air in the dock so they don't sit damp between sessions. The P50 Ultra skips all three. Its obstacle detection does add an LED to the AI, camera, and 3D structured light setup, which helps in dim hallways and under furniture.
The Mova P50 Ultra's 19,000 Pa gives it a clear pulling advantage over the X40 Ultra's 12,000 Pa, and both use the same single rubber main brush, which resists hair tangles better than bristle designs. That said, the Dreame's liftable main brush keeps the roller out of the way during mop-only passes.
Both use dual spinning mop pads, the strongest mainstream mopping setup because the pads actively scrub with downward pressure instead of just dragging. The X40 Ultra edges ahead on the details: it detaches its pads automatically before carpet and dries them with air afterward, plus it carries an onboard water tank for topping up mid-run.
Pet households benefit from the P50 Ultra's higher 19,000 Pa suction, which lifts hair woven into rug fibers more reliably. Both robots use a single rubber main brush, the design that handles long hair with the least wrapping.
Both robots combine LiDAR mapping with AI camera obstacle avoidance and 3D structured light, so both build accurate maps and dodge cords and socks. The P50 Ultra adds an LED to that stack, which helps the camera see clearly in dark rooms and under low furniture.
Each dock empties the dustbin on its own and washes the mop pads, so daily upkeep is minimal either way. The X40 Ultra's dock also dries the pads with air, which keeps them from developing a musty smell between cleans.
The Dreame X40 Ultra's 6,400 mAh battery is the larger of the two against the P50 Ultra's 5,200 mAh, giving it more runtime per charge. That matters most in bigger single-floor layouts where fewer recharge breaks means the job finishes sooner.
The two are matched here. Both support Amazon Alexa, Google Assistant, and Apple voice control, plus no-go zones and multi-level maps for houses with more than one floor.

Both are strong picks with identical feature and value ratings, so neither is a mistake. Go with the Mova P50 Ultra if suction and carpet performance top your list. Pick the Dreame X40 Ultra if longer runtime and hands-off surface switching matter more than peak power.
