The Yeedi S20 Infinity is a robot vacuum and mop combo with a bagless auto-empty dock, positioned as a more affordable alternative to Ecovacs’ flagship Deebot X11 OmniCyclone. Yeedi, an economy brand owned by Ecovacs Robotics, often brings premium features to lower price points, and the S20 Infinity appears to follow that pattern. We purchased one and tested it over several weeks to see how it performs in real-world use. In this Yeedi S20 Infinity review, we compare it directly to the X11 to determine how much of that flagship-level experience carries over—especially for homes with heavy debris or pet hair, where a bagless system could offer a practical advantage.
The Yeedi S20 Infinity is a high-performing upper mid-range robot vacuum that closely mirrors a flagship model while offering strong value, especially for homes with pets. In testing, it excelled with an 89% carpet deep clean score, a perfect 100% pet hair pickup, zero hair tangles, and top-tier suction and airflow results, along with above-average obstacle avoidance (21/24 objects) and highly efficient navigation and battery performance. Its key pros include a rare bagless dock that avoids recurring costs, excellent vacuuming across surfaces, effective anti-tangle brush design, strong app features, hot water mop washing and drying, and a roller mop system that handles liquid messes well and lifts on carpet. However, the cons include extremely poor mopping results on dried stains due to low water usage (though real-world results were better, suggesting possible firmware or testing issues), occasional hair buildup inside the dock requiring manual cleaning, a small 220 ml onboard dustbin that may clog more easily, and no live video monitoring in the app. Overall, it’s a powerful, low-maintenance vacuum with inconsistent mopping performance.

Yeedi S20 Infinity Review: Overview and Market Position
The S20 robot vacuum is in the upper-middle tier, with a list price of around $1,000, though it’s frequently on sale. The Ecovacs X11 OmniCyclone (See our full review) is in a more premium tier, but often sells for much less than its list price. Since the S20 Infinity is essentially a direct alternative to the X11, we’ll often compare the two in this review.
Yeedi S20 Infinity vs Ecovacs X11 OmniCyclone
Bagless Auto-Empty Dock
One of the most important features of the Yeedi S20 Infinity is the bagless dock. Bagless docks are pretty uncommon with robot vacuums, so users who prefer bagless conventional vacuums can have a hard time finding that feature on robots.
Disposable bags can be costly, and the recurring expense of replacing them can eventually add up, especially for homes with a lot of pet hair, since that means more bag changes.
On the X11 (which has the same OmniCyclone bagless dustbin), we noticed some dampness in the dustbin, causing hair to clump and making it harder to clean. This was reflected in our water penalty assessment, where the X11 incurred a 0.70-gram penalty. We didn’t notice this happening on the Yeedi, which saw a much lower penalty of just 0.20 grams. That’s well below the 1.07-gram category average.
This really improved our opinion of the dock design. However, we did notice some hair getting caught in the upper area between the cyclone unit and the plastic housing of the Yeedi S20 Infinity’s bin.
To fully clear that out, we had to remove the filter and open the bin, which isn’t ideal, but it didn’t happen every time. Either way, it’s a relatively small price to pay for the ability to collect a lot of hair and debris without needing disposable bags.
Top 20 Robot Vacuums
Vacuum Wars’ always up-to-date rankings of the best robot vacuums. Because we purchase every unit ourselves, each recommendation is built on hands-on data. Our work now spans more than 150 models, giving us a deep benchmark for judging cleaning power, navigation smarts, battery life, and advanced features such as obstacle avoidance and mopping.
Mopping Dock Features (Hot Water Washing and Drying)
The Yeedi S20 Infinity robot vacuum dock washes the mop by soaking it in water up to 167°F and drying it with hot air up to 145°F.
Vacuuming Performance and Pet Hair Pickup
Like the X11, the S20 Infinity was a vacuuming powerhouse. The main brush bristles resist hair wrapping, and a single fixed side brush directs debris into the suction path. It performed very well at its main job of sweeping debris of various sizes from hard floors and carpets without scattering. It also earned an above-average score in our carpet deep clean evaluation.
For this assessment, we embed sand into medium-pile carpet and measure how much the robot vacuum can remove. The S20 Infinity surprised us with a high score of 89%—higher than the X11’s 85% and much higher than the 78% category average.
The S20 earned a rare 100%, like the X11, in our pet hair evaluation (where we press 2.5-inch hair into carpet). It beat the 82% average by nearly 20%.
The Yeedi also performed really well in our 7-inch hair-tangle evaluation. Yeedi’s ZeroTangle system on the main brush worked perfectly, with 0% of hairs wrapping around it, matching the X11 and significantly outperforming the 46% average.
Hair wrapping can cause motors to work too hard and prevent brushes from properly agitating the floor, so we really like to see anti-tangle systems work as intended.

Suction Power and Airflow Performance
Suction and airflow were very strong with the Yeedi S20 Infinity. Suction performance measured 2.47kPa, which is one of the highest numbers we’ve seen, even greater than the X11’s 2.35kPa and far beyond the 0.99kPa average.
Airflow was also really impressive. The S20 Infinity clocked in at 24 cfm (a top-5 score), compared to the X11’s 23 cfm and the 16.95 cfm average.
OZMO 2.0 Roller Mop System Explained
The mopping hardware on the Yeedi S20 is OZMO 2.0, a continuous-clean roller mopping system that’s the same as the X11’s on paper.
With this system, the robot vacuum refills the roller’s clean water and drains the used water into an on-board dirty water tank, so it isn’t left behind on the floor. This type of mop is excellent for handling liquid messes, since the robot collects wet materials rather than spreading them across the floor like spinning mops.
The S20 Infinity’s roller extends to the side for edge coverage and has several adjustable water flow settings with the same downward pressure as the X11. Its roller also lifts 10 millimeters when the robot vacuum detects carpets, allowing it to clean both hard floors and carpets simultaneously.
Obstacle Avoidance with AIVI 3D Technology
Another pro is the S20 Infinity’s obstacle avoidance. It shares the same system as the Ecovacs X11, called AIVI 3D. It’s a multi-sensor system that uses an RGB camera and 3D structured light with AI object recognition.
Between our basic and torture evaluations, the Yeedi S20 Infinity successfully avoided 21 out of 24 possible objects. It did better than the X11’s 20/24 score and the 16/24 average.
Navigation Capabilities
Navigation was another positive. The Yeedi S20 Infinity outperformed the Ecovacs X11 by a significant margin. Both robots use embedded time-of-flight LiDAR to map and navigate the floorplan, but the S20 Infinity’s navigation outperformed the X11 by almost double. It achieved 0.76 square meters per minute, compared to the X11’s 0.39 and the average of 0.71.
Battery Life and Charging Performance
The S20 Infinity achieved 3.35 minutes per 1% battery, which is excellent and nearly the same score as the X11’s 3.4 minutes—both of which were more efficient than the 1.56 average.
The Yeedi could cover an estimated 2,740 square feet per charge, vastly outperforming the X11’s 1,435 square feet and the 1,170 average.
These results suggest it’s unlikely the S20 Infinity will run out of battery during a cleaning run. And in the unlikely event that it does, the robot vacuum can quickly recharge while washing its mop between rooms. It gains a 6% charge in 3 minutes.
App Features and Smart Home Integration
Yeedi’s App is very similar to the Ecovacs app and supports all the controls you would expect from a major robot vacuum brand. You can manage room customizations, multi-floor mapping, zone cleaning, no-go zones, and individual room selection and settings. It even integrates with third-party voice assistants.
You can also choose to have the robot mop in the direction of the floor, which can minimize streaks. However, the Yeedi S20 Infinity doesn’t support video access through the app. That means there isn’t live video monitoring.
Cons of the Yeedi S20 Infinity
Mopping Performance Issues and Other Observations
The biggest drawback we found was with the Yeedi S20 Infinity robot vacuum’s mopping performance. But we have reasons to believe the results don’t tell the whole story.
In our dried-on stain evaluation, the Ecovacs X11 OmniCyclone scored a respectable 137 points—well above the 108 average for robot vacuum and mop combos.
See also: How Vacuum Wars Tests Robot Vacuum Mops
However, despite using what appears to be the same OZMO Roller 2.0 mopping system, the Yeedi S20 scored only 37 points. This is one of the lowest marks we’ve seen for a mid-range robot vacuum and mop combo.
The gap narrowed slightly in the coffee stain evaluation. But the X11’s 88 points score is still significantly better than the Yeedi’s 22 points, even though both fell below the 94-point lab average.
As noted earlier, we also evaluate water usage and flow because high-output robots can often leave streaks on hardwood floors. The X11 maintained below-average water use, which is impressive given its high cleaning score.
In contrast, the Yeedi S20 used far less water on the same setting, and this restricted water flow seemed to hinder its ability to handle tough messes in a studio environment. It resulted in a low combined mopping efficiency score for the Yeedi, while the Ecovacs remained a top performer.
This difference was puzzling since both units share the same roller mop hardware. However, we began to question the studio results after actual use at home. The Yeedi S20’s mop distributed enough water and performed identically to the X11 in a typical home environment. This leads us to believe the initial lab results may have been due to a firmware bug or a temporary sensor calibration issue that has since been patched.
Dustbin Size and Maintenance Considerations
Another potential drawback is the small onboard dustbin, which is only 220 mL. It’s the same size as the X11 but quite small compared to the more typical 375 mL average for robot vacuums. This increases the risk of clogs if the dustbin overfills before auto-emptying.
Final Verdict: Is the Yeedi S20 Infinity Worth It?
After adding up the scores and evaluating features and value, the Yeedi S20 Infinity ranks slightly above the Ecovacs X11 overall. Both currently sit very high on the Vacuum Wars Top 20 Robot Vacuums list, with the Yeedi just pulling ahead. The S20 Infinity delivers a very powerful vacuum that’s particularly good at picking up hair. In fact, the entire system is shaping up to be really great for pet hair—possibly becoming our favorite if these patterns continue.
