The cleaning performance of the Eufy X9 Pro had excellent ratings across all of our cleaning tests. It excelled at capturing both our larger debris and our small granular debris like sugar across hardwood, low and high pile carpets, and its mopping capabilities.

To test the debris removal performance of the Eufy X9 Pro, we put it through a series of 12 different cleaning tests consisting of 3 different floor types and 4 different debris types.

We measure 0.5 oz. of each debris type, spreading it evenly across the floor for the vacuum to clean. Next, we run the Eufy X9 Pro over the debris on the highest suction power, letting it perform 2 complete cleaning cycles. After, we measure how much of the debris remains by weight and compare it to the starting amounts to determine cleaning performance.

Here are the overall results for the Eufy X9 Pro:

In our debris tests, the Eufy X9 Pro was able to remove 90% of debris by weight. This is 2.2% lower than the average of 92.2%, based on all of our debris tests to date.

The Eufy X9 Pro was able to navigate over the hardwood floor and hit all corners of the testing area. Additionally, during its first cleaning cycles, it removed a significant amount of debris in the testing field.

In our hardwood tests, the Eufy X9 Pro was able to remove 99% of debris by weight. This is 1.9% higher than the average of 97.1%, based on all of our debris tests to date.

During testing, we observed the brush push some of the debris across the testing area rather than capturing the debris. However, on the next pass of cleaning, the X9 would capture the materials.

Low-pile carpet was not an issue for the Eufy X9 Pro. It navigated well over the low pile carpet with ease and was able to hit all sections of the testing area.

In our low pile carpet tests, the Eufy X9 Pro was able to remove 84% of debris by weight. This is 5.3% lower than the average of 89.3%, based on all of our debris tests to date.

While the Eufy X9 Pro navigated over the area, it did not capture all the material. Mainly it was the larger debris that the X9 Pro either missed or struggled to remove.

In our high pile carpet tests, the Eufy X9 Pro was able to remove 87% of debris by weight. This is 2.8% lower than the average of 89.8%, based on all of our debris tests to date.

During the testing of the high pile carpet, we did notice that the Eufy X9 Pro took its time in cleaning the carpet. Sometimes moving over an area several times to ensure proper cleaning.

To test how well the Eufy X9 Pro manages long hair and avoids tangles, we pit it against 0.3 grams of long hair. We lay the strands of the hair on the hardwood flooring and run the vacuum over it on the maximum suction power with a single forward and backward pass. After cleaning, we check the floor for hair and the brush roll for tangles.

In our long hair tests, the Eufy X9 Pro had only 73% of the total hair laid in the testing area tangled in its roller This is 19.3% more hair than the average of 53.7%, based on all of our long hair tests to date.

When inspecting the brush roller after the test, we observed hair around the roller, inside the bearing of the roller, and some hair located around the side brush. With the detachable roller and brush, it took only a few seconds to remove them and clean out the tangled hair.

For our pet hair test, we embed 1.0 grams of pet hair into high pile carpet. Next, we run the vacuum over the carpet with a single forward and backward pass on the highest suction power. Finally, we measure the amount of remaining pet hair in the carpet and compare it to the starting amount to determine performance.

In our pet hair tests, the Eufy X9 Pro removed 90% by weight. This is 43.7% better than the average of 46.3%, based on all of our pet hair tests to date.

While inspecting the Eufy X9 Pro roller after the pet hair test, we observed no hair tangled in the roller. However, not all pet hair is the same. You should observe the X9 Pro during its first cleaning cycle to see how well it interacts with your pet’s hair.

For our edge cleaning test, we test to see how close to the edge the Eufy x9 Pro can clean. To test this, we place 0.3 oz of debris (sugar, kitty litter, and a little bit of rice) directly along the edge of the wall, to about 4.0″ away from the wall.

We then run the vacuum over the debris, towards the wall, on the highest suction power with a single forward and backward pass. We then measure in inches how close the vacuum was able to clean in proximity to the wall and how much of the debris remained by weight.

In our edge cleaning tests, the Eufy X9 Pro was able to remove 78% of debris by weight.

The Eufy X9 Pro had excellent results on our edge test. Its rotating brush was able to get close to the baseboard, moving the debris closer to the Eufy X9 Pro dustbin collector. However, as the X9 Pro was moving around the edges, the brush would push the debris around the entire testing area, eventually being cleaned up as the robot continued its cleaning cycle.

To test the crevice cleaning capabilities of the Eufy X9 Pro, will fill 3 crevices in our tile testing lane with 0.1 oz of sugar each, totaling 0.3 oz. We then let the robot complete a single cleaning cycle on the highest suction power and check how much of the sugar remains by weight to determine performance.

In our crevice tests, the Eufy X9 Pro was able to remove 90% of debris by weight from the deepest crevice.

While observing the Eufy X9 Pro pass over the sugar-filled crevice, it had excellent suction power in removing any visual indication of sugar in the testing area.

To test the mopping capabilities of the Eufy X9 Pro, we check how well it can remove dirt on a broader scale.

In our mop test, the Eufy X9 Pro showcased excellent performance. On average, based on all of the robot-mop devices we’ve tested to date, we find they have very good performance. The Eufy X9 Pro is better than our testing average.

With the 1 kg of downward pressure from the mopping pads, we noticed a significant amount of dirt captured in the dirty water collection bin. Throughout the several days of testing, the mop heads were able to dry / clean after every cleaning cycle, ensuring the floor was not being cleaned by dirty mopping heads.

How well a robot vacuum can navigate and clean the home can greatly impact the overall user experience. To check how well the Eufy X9 Pro navigates, we focus on these key factors.

Our cleaning speed test showed the Eufy X9 Pro was able to clean our ~1,000 sq. ft. office space within 45 minutes.

The average cleaning speed we find, based on all robot vacuums we’ve tested to date, is 63 minutes. The Eufy X9 Pro is 18 minutes faster than the average.

The cameras on the X9 were an update from the previous X8 model. The new RGB camera and LiDAR offer exceptional obstacle avoidance and detection.

To test the obstacle avoidance of the Eufy X9 Pro, we place 4 objects in an area on the floor and send the robot to clean around them. We observe the cleaning cycle, checking to see how well the robot vacuum navigates the space and avoids objects.

The Eufy X9 Pro had excellent obstacle avoidance performance in our tests. On average, based on all the robot vacuums we’ve tested to date, robots seem to struggle the most when avoiding cords and the mug. In both cases, the X9 performed better.

During testing, the Eufy X9 Pro was able to avoid the cord, shoe, and fake pet waste by navigating around the objects to clean. Unfortunately, the X9 did have a partial touch on our testing mug. Only after it tapped the mug with its front bumper did it register the object and clean around it.

We also test how well the Eufy X9 Pro cleans on a broader scale. We have the robot perform multiple cleaning cycles in our office and studio space, focusing on 3 core requirements: can it fully clean the space, can it not get stuck, and can it return to the base?

The Eufy X9 Pro had excellent navigational performance in our cleaning efficiency tests. On average, we find robot vacuums are very good when navigating our office and studio space. The Eufy X9 Pro is better than average.

The cleaning history showed that with each cleaning cycle, it was able to navigate and clean throughout the whole testing area before returning to its base.

Our build quality test is a subjective test where we examine and assess the major material and design components of the robot vacuum. Specifically, we are looking for build and design issues that are more likely to break and / or be difficult to use.

Both the Eufy X9 Pro and base station are constructed out of plastic material. The robot itself felt sturdy and well-constructed. The base station however felt a little fragile. The plastic walls of the station are thin.

Part	Build Quality
Overall	Excellent
Body	Excellent
Dust Bin	Good
Display / Controls	Excellent
Spinning Side Brush	Very Good
Wheels	Very Good
Brush Roll	Very Good
Charging Dock	Excellent

Nearly all of the robot vacuums we test have plastic robot bodies and base stations. The major difference with the Eufy X9 Pro base station is the walls feel thinner than other robot base station.

Vacuums are loud while in operation. To measure how loud, we run them on high pile carpet on each power mode and measure the noise generated with a sound meter. Before the test, we take a measurement of the ambient noise in the room to use as a baseline comparison to the vacuum. 

Power Level	Noise Level
Ambient	40 dB
Quiet	58 dB
Standard	60 dB
Turbo	65 dB
Max	67 dB

In our noise tests, the Eufy X9 Pro generated 67.4 dB of noise at the max suction speed. This is 1.8 dB higher than the average of 65.7 dB, based on all of our noise tests to date.

An interesting feature of the Eufy X9 Pro was the mopping heads. Instead of one long mopping head that sits at the rear like most robot vacuums, it had two independent heads that would raise and lower. This feature is useful for the robot to fully clean a space without a wet or dirty mop head dragging against carpets or rugs.

The setup was simple and easy. The robot itself comes pre-assembled with a slight battery charge and only a few plastic covers to remove.

• The base needs to be plugged in.
• The clean water tank will need to be filled. 
• All that is left to do is set up the app with an account and select your robot settings.

In total, the setup was about 5 minutes.

The Eufy App is simple and user-friendly to set up.. It offers a wide variety of options to help program your Eufy X9 Pro to your specific needs. You can adjust the suction power, vacuum / mop power, zone cleaning, and scheduling. It also allows you to control any other Eufy products you already own.

With the app you can:

• Manage maps
• Manage schedules
• View cleaning history
• Set carpet cleaning settings
• Adjust base station settings
• Manual controls
• Voice settings
• AI.see Camera settings
• Robot settings

The robot itself only has three buttons on top.

• Power Button – starts and pauses the cleaning cycles. 
• Home Icon – returns the vacuum to the base station to recharge.
• The square button enables / disables the Eufy X9 Pro’s spot-cleaning mode.

There are no buttons on the base charging station. All functions not available on the robot vacuum are controlled through the app.

Product Evolution

The Eufy X9 Pro is the successor to the X8 Hybrid. The most notable update in the newer X9 Pro model is the addition of the base charging / cleaning station. The base station can clean and dry the dual mop heads after each cleaning cycle. It also can empty the dirty water and refill it with clean water before the next cleaning.

Also updated on the new model was the camera. The Eufy X9 Pro has an RGB camera with LiDAR as opposed to the X8 hybrid which is only infrared.

The X9 Pro offered a similar level of cleaning performance compared to the X8 Hybrid. The usability is a real improvement over the X8. The base station that washes the mopping pad is a wonderful extra. My only major complaint is that the base station doesn’t empty the dry debris bin.
