The Deebot X9 Pro Omni is the latest flagship robot vacuum mop combo from Ecovacs, and we bought one for ourselves to evaluate over several weeks. If you’ve already seen our Robot Vacuum Awards Show for mid-2025, you know the X9 Pro was the big winner. It took home five awards, including the Best Overall Robot Vacuum award. In our Ecovacs Deebot X9 Pro Omni review, we’ll cover the pros and cons of the X9 and explain why it was such a big winner this year. In fact, the X9 is currently ranked number one on the Vacuum Wars Top 20 list, and second place is a distant second.
The Ecovacs X9 Pro Omni is a robot vacuum/mop combo featuring 16,600Pa of suction power enhanced by BLAST airflow technology for improved carpet cleaning efficiency. Its OZMO Roller instantly self-washes during mopping to maintain cleanliness and avoid streaks. Equipped with ZeroTangle 3.0 technology, it utilizes a V-shaped roller and anti-tangle side brushes to prevent hair wraps. Its Triple Lift System automatically adapts to different surfaces, lifting the mop on carpets, side brush for large debris, and main brush to avoid contamination. AI-driven navigation with AIVI 3D 3.0 and LiDAR ensures obstacle avoidance and targeted cleaning. Additional features include TruEdge 2.0 edge sensors for comprehensive cleaning, AI Stain Detection 2.0, a long-lasting EV-grade 6400 mAh battery, voice and app controls (compatible with Alexa, Google Assistant, and Matter), and an OMNI Station that provides automatic maintenance—washing, drying, and dispensing cleaning solution—for up to 150 days between manual refills.

Performance
Ecovacs recently introduced what they call Blast Technology. That means they’ve upgraded various aspects of their motor to produce more airflow. They argue it’s more important than suction when it comes to robot vacuum performance, and we would agree.
In our airflow tests, the Ecovacs X9 Pro Omni delivered an impressive 27 CFM, making it one of the highest airflow scores we’ve ever recorded. For comparison, the Roborock Saros 10R measured 15 CFM, and the average among similar models is 16 CFM.
In suction tests (at maximum power), the X9 Pro Omni reached 2.76 kPa, significantly outperforming the Roborock Saros 10R at 0.58 kPa, and the overall average of 0.83 kPa.
The X9 uses a single main brush in a floating housing, paired with a single side brush, to sweep debris from the surfaces of hard floors and carpets. We found this combination excellent in our evaluations.
It swept up everything from fine to extra-large debris from both surface types very efficiently and without scattering. The side brush appears to have been slowed down compared to previous versions, where scattering was an issue. (With this performance, the X9 won our Best Robot Vacuum for Hard floors, Mid- 2025.)
Practical Performance Evaluations
The Ecovacs X9 Pro Omni also excelled in our carpet deep clean test, which measures how effectively a robot vacuum can remove deeply embedded debris. It achieved an outstanding 89%, tying for the highest score we’ve ever recorded among robot vacuums that have a lifting mop mounted underneath.
For comparison, the Roborock Saros 10R scored 80%, and the average across similar models is 75%.
This score won the X9 Pro Omni our Best Robot Vacuum for Carpets, Mid-2025.
The Ecovacs X9 Pro Omni also performed exceptionally well in one of our more challenging tests: the 2.5-inch flattened pet hair pickup assessment. It managed to collect an impressive 93% of the hair, far surpassing the average score.
In comparison, the Roborock Saros 10R picked up 67%, and the average across models is just 70%.
The Ecovacs X9 Pro Omni is equipped with the brand’s new Active Hair Removal System, which uses small plastic combs inside the brush housing to reduce hair tangles. In our 7-inch hair tangle test, it achieved a perfect score, with 0% of the hair getting tangled—a significant improvement over the average of 38%.
Mopping System
One of the biggest pros of the X9 Pro Omni was its mopping ability. The robot vacuum mop combo uses a single roller-style mop that automatically lifts when the robot senses carpets to keep them dry.
It also automatically extends its mop roller to the side when it’s near edges for better edge coverage, and it did well in our evaluations.
The way the roller works is that water is sprayed onto the roller as it spins. Unlike dual-spinning pads or flattened mop pads, roller-style mops can process wet liquids by squeezing out dirty water into an onboard water tank. That means they can pick up wet spills without spreading them around, while other style mops are limited to mopping primarily dried-on stains.
The Ecovacs X9 Pro Omni also stood out in our dried-on stain mopping test, earning 158 out of a possible 184 points—one of the highest scores we’ve ever recorded for this evaluation.
In addition, it left behind significantly less water than most competitors, which is a big plus for preventing streaks and promoting faster drying. It left just 0.70 grams of water behind, compared to 1.05 grams for the Roborock Saros 10R and an average of 1.01 grams across all tested models.
When you combine those scores with its other mop features, it’s no surprise that the X9 won the Best Robot Vacuum Mop, Mid-2025.
Multifunctional Dock
We can’t talk about its mopping system without mentioning the multifunctional charging dock. When the robot returns to its base to charge, it will automatically wash the mop pads with hot water, dry them with hot air, refill the clean tank, and empty the dirty water tank.
One new feature here is that the temperature of the water for mop pad washing can be adjusted depending on the likely level of dirtiness in the room. The base also has a dirty water sensor, which determines how often the pads need to be washed.
Additionally, there’s a detergent reservoir if you want the dock to mix mopping solution with clean water.
It also comes with a fairly large 3-liter disposable bag for dry debris, which Ecovacs claims can hold up to 3 months of debris before needing to be replaced.
The dock has a self-cleaning cycle using sprayers. It also has fast charging and Matter support, all of which are premium features for docks.
Obstacle Avoidance and Navigation
Another advantage was its obstacle avoidance. The Ecovacs X9 Pro Omni has several front-mounted sensors, including a camera, structured light, and time-of-flight sensors. These help the robot recognize and avoid household objects that it would otherwise get stuck on.
The X9 Pro Omni’s system is trained to recognize over 200 common household objects and includes a low-light LED that automatically activates to help it navigate in darker environments.
In our series of obstacle avoidance tests, the Ecovacs X9 Pro Omni scored 19 out of 24 possible points, performing above average in this category. For comparison, the Roborock Saros 10R scored a perfect 24, (winning our Best Robot Vacuum Obstacle Avoidance, Mid-2025, so the competition was stiff!) while the average score is 17.
When it comes to navigation, the Ecovacs X9 Pro Omni uses an internal LiDAR system to map and move through its environment. It performed very well in our navigation tests, earning a navigation efficiency score of 0.93 m² per minute, which is well above the average.
By comparison, the Roborock Saros 10R scored 0.67 m²/min, and the average across all models is 0.70 m²/min.
App Experience
Ecovacs makes a top-tier app that’s easy to use with lots of features and control over the robot vacuum and its bin behaviors. The app features the YIKO virtual voice assistant, multi-level maps, and virtual barriers and allows you to control how often it empties the bin or cleans the brush. It also offers various pet-related features.
Cons of the Ecovacs Deebot X9 Pro Omni
Despite winning so many awards this year, there were a few things to pick on with the X9. It’s rare to find a truly perfect product, and our Ecovacs Deebot X9 Pro Omni review won’t be complete without this section.
The biggest drawback we found with the Ecovacs X9 Pro Omni was its battery performance. While its official battery life at the lowest power setting is quite good—200 minutes, compared to 180 minutes for the Roborock Saros 10R and an average of 148 minutes—its real-world performance at higher power settings was noticeably underwhelming.
In our tests, the Ecovacs X9 Pro Omni earned a below-average battery score. Both its battery efficiency and average square footage cleaned per charge were lower than what we typically see.
In the battery efficiency test, which measures how many minutes of runtime are delivered per 1% of battery, the X9 managed just 0.88 minutes per percent. That’s considerably lower than both the Roborock Saros 10R at 1.69 and the category average of 1.31.
As for coverage per charge, the X9 cleaned 876 square feet on a full battery. In contrast, the Roborock Saros 10R cleaned 1,218 square feet, and the average across models is 1,015 square feet.
This is probably due to its higher-than-average airflow and suction scores, as we mentioned earlier. And, of course, it has recharge and resume capabilities, so it will return automatically to its dock if it’s low on battery, charge up, and then continue where it left off on the map. Nevertheless, battery life was one of the few weak points in an otherwise stellar robot vacuum.
Another downside is the height of the Ecovacs X9 Pro Omni. Despite using an internal LiDAR system, which typically allows for a lower profile, the X9 measures approximately 3.80 inches tall—slightly above average.
The Ecovacs X9 Pro Omni also has a smaller-than-average internal dustbin, with a capacity of just 220 milliliters. This is well below the average of 388 milliliters across robot vacuums we’ve tested.
For reference, the Roborock Saros 10R offers a slightly larger bin at 270 milliliters, but both fall short of the category average—meaning the X9 may need to return to its station to empty the dustbin more frequently during use.
Another, more nitpicky drawback is that the Ecovacs X9 Pro Omni is missing a few features we’ve started to expect from flagship models. For instance, it doesn’t include an auto-extending side brush, a feature that can significantly improve edge and corner cleaning.
It also lacks advanced threshold-crossing capabilities that have begun appearing in newer models this year. The X9 can handle standard thresholds up to 20 mm, which matches the category average, but falls short of models like the Roborock Saros 10R, which can cross thresholds up to 40 mm.
Ecovacs Deebot X9 Pro Omni Review: Conclusion and Recommendation
Overall, the X9 Pro Omni is one of the best robot vacuum mop combos we’ve ever evaluated. So it’s no surprise it won so many awards or that it ranks Number One on the Vacuum Wars Top 20 list as of this article.
However, the X9 Pro Omni is still a brand-new product. So, we’ll closely monitor Amazon reviews to ensure there are no long-term deal breakers that we missed in our initial review. But right now, if you’re looking for the best robot vacuum on the market at any price, the Ecovacs X9 Pro Omni is it.
