Best For

  • Hard floor surfaces (wood, tile, vinyl, etc.) – removed 99% of debris in our tests
  • Obstacle avoidance – Avoided 3 out of 4 obstacles, while only slightly touching the 4th
  • App connectivity displays a wide range of information

Considerations

  • No auto-empty dust bin in the base station
  • Vacuuming carpet took notably longer

Our Verdict

The Eufy X9 Pro is the latest robot vacuum from Eufy. It has excellent cleaning capabilities with both vacuum and mopping features. In our debris cleaning tests it was able to remove 90% of debris by weight. Its app connectivity allows the user to have in-depth control over cleaning modes, scheduling, and locations.

In addition, it easily navigates around objects with excellent object avoidance / detection. The base charging stations feature a large freshwater reservoir with an additional large dirty water tank. However, the base station does fall short in not having a debris auto-emptying bag. This means you have to manually monitor the debris bin on the robot and empty it frequently.

Overall Debris Test

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.

Eufy X9 Pro Front Sideview
Eufy X9 Pro Front

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.

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.

84

Low Pile Carpet Test

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.

Eufy X9 Low Carpet Test
Low Carpet (Before)
Eufy X9 Low Carpet Final
Low Carpet (After)

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.

87

High Pile Carpet Test

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.

Eufy X9 High Carpet Debris Test

High Carpet (After)

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.

27

Long Hair Test

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.

Amount Removed

100%

Hair Tangle Avoidance

27%

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.

Eufy X9 Pro Long Hair Roller

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.

90

Pet Hair Test

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.

Amount Removed

90.0%

Amount Tangled

0%

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.

Eufy X9 Pet Hair Dust Bin
Eufy X9 Pro Pet Hair Dust Bin

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.

81

Edge Cleaning Test

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.

Amount Removed

78.0%

Edge Cleaning Proximity

0.5″

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

Eufy X9 Pro Edge Test Results
Eufy X9 Pro Edge Test Results

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.

90

Crevice Cleaning Test

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.

Amount Removed

90.0%

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.

92

Mop Test

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.

98

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.

Cleaning Speed

45 min.

Obstacle Avoidance

Yes

Cleaning Efficiency

Exceptional

94

Cleaning Speed

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

Cleaning Area

~1,000 sq. ft.

Cleaning Speed

45 min.

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.

93

Obstacle Avoidance

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.

Shoe

Yes

Mug

Partial

Cord

Yes

Pet Waste

Yes

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.

100

Cleaning Efficiency

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?

Build Quality Test

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.

Eufy X9 Pro Base Station Frontview
Eufy X9 Pro Base Station Frontview

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.

PartBuild Quality
OverallExcellent
BodyExcellent
Dust BinGood
Display / ControlsExcellent
Spinning Side BrushVery Good
WheelsVery Good
Brush RollVery Good
Charging DockExcellent

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.

Noise Test

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 LevelNoise Level
Ambient40 dB
Quiet58 dB
Standard60 dB
Turbo65 dB
Max67 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.

100

Usability

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.

Setup

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.
