For cleaning performance, the Eureka E10s was able to remove a significant amount of debris from our testing lanes. At times it struggled to collect the debris on its first pass. However, with a second pass, a healthy amount of debris was removed.

To test the debris removal performance of the Eureka E10s, 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 Eureka E10s 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 Eureka E10s:

In our debris tests, the Eureka E10s was able to remove 91.0% of debris by weight. This is 1.5% less debris than the average of 92.5%, based on all of our debris tests to date.

The E10s came in below our testing average slightly. Its performance on the Hardwood was not what we typically see from robot vacuums and impacted the overall debris removal score.

The performance on the hardwood was disappointing for what is typically an easy debris test.

In our hardwood tests, the Eureka E10s was able to remove 88.0% of debris by weight. This is 9.1% less debris than the average of 97.1%, based on all of our debris tests to date.

As the robot traveled over the debris, it left a trail of material directly underneath the robot. The robot simply did not have enough suction power to remove all the debris in its path. Additionally, the side spinning brushes often pushed the material across the testing floor, missing the robot’s collection roller.

The robot had better performance on the low pile carpet than both the high pile carpet and hardwood surface.

In our low pile carpet tests, the Eureka E10s was able to remove 93.5% of debris by weight. This is 3.8% more than the average of 89.7%, based on all of our debris tests to date.

Unlike the hardwood floor, the debris had more friction with the carpet, preventing the debris from spreading.

The high pile carpet score came in just behind the low pile carpet with a score near our testing average.

In our high pile carpet tests, the Eureka E10s was able to remove 91.7% of debris by weight. This is 1.5% more debris than the average of 90.3%, based on all of our debris tests to date.

The leftover debris was primarily the small sugar and litter with a few pieces of cereal. The smaller debris often sinks deep into the carpet, making it difficult for the robot’s suction to remove the debris.

To test how well the Eureka E10s 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 completing 2 cleaning cycles. After cleaning, we check the floor for hair and the brush roll for tangles

In our long hair tests, the Eureka E10s had only 30% long hair tangle by weight. This is 19.2% less long hair than the average of 49.2%, based on all of our long hair tests to date.

While it did pick up all of the hair off the testing surface, some of it tangled in the brushroll. Most of the tangled hair was wrapped around the side bearing where the roller is connected to the robot.

For our pet hair test, we embed 1.0 grams of pet hair into a high pile carpet. Next, we run the vacuum over the carpet completing 2 cleaning cycles on the highest suction power. Finally, we measure the amount of remaining pet hair on the carpet and compare it to the starting amount to determine performance.

In our pet hair tests, the Eureka E10s removed 98.0% of pet hair by weight. This is 22.4% more hair than the average of 75.6%, based on all of our pet hair tests to date.

While it collected a majority of the pet hair in the high pile carpet, there was a small amount that was tangled in the fibers of the collection roller. It was easy to remove and was not wrapped around the roller.

It is important to note that not all pet hair is the same. We recommend monitoring the performance of the robot if your pet has long hair.

For our edge cleaning test, we test to see how close to the edge the E10s 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, about 4.0″ away from the wall. We let the vacuum complete 2 cleaning cycles in our enclosed testing lane.

Finally, we 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 Eureka E10s was able to remove 60.3% of debris by weight. This is 26.9% less debris than the average of 87.2%, based on all of our edge cleaning tests to date.

The main issue we saw with this test was the robot failing to maintain coverage over the length of the wall. It never navigated close and parallel to the wall, which left gaps of debris as it continuously turned away from the wall.

The front bumper would register a wall hit, then immediately turn away, move forward a few inches, then turn back into the wall, repeating the cycle.

To test the crevice-cleaning capabilities of the Eureka E10s, 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 Eureka E10s was able to remove 99.3% of debris by weight from the crevices. This is 0.3% less debris than the average of 99.0%, based on all of our crevice tests to date.

The Eureka E10s had an exceptional performance on our crevice test. It was able to remove the sugar places in the shallow crevices without issue.

To test the mopping capabilities of the Eureka E10s, we check how well it can remove small-scale stains and remove dirt on a broader scale.

In our mop test, the Eureka E10s showcased excellent mopping performance.

As you can see in the comparison image above, the mopping pad removed dirt from our office floor during the tests. Unfortunately, the base station does not have a mop head cleaning function, which means you’ll need to regularly clean the pad.

How well a robot vacuum can navigate and clean the home can greatly impact the overall user experience. To check how well the Eureka E10s navigates, we focus on the key factors.

Our cleaning speed test showed the Eureka E10s was able to clean our ~1,000 sq. ft. office space within 48 minutes.

The average cleaning speed we find, based on all robot vacuums we’ve tested to date, is 60 minutes. The Eureka E10s is 12 minutes faster than the average.

The Eureka E10s comes with a LiDAR top-mounted sensor.

To test the obstacle avoidance of the Eureka E10s, we placed 4 objects in an area on the floor and sent 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 E10s had poor obstacle avoidance when trying to navigate around everyday objects. It had partial touches on the shoe and cord but completely failed to see the pet waste. However, it was able to completely navigate around our Modern Castle testing mug.

This poor performance might result in your E10s moving, bumping, and sometimes dragging your belongings across the floor.

We also test how well the Eureka E10s 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 E10s had terrible navigational performance in our tests. On average, we find robot vacuums have excellent performance when navigating our office and studio space. The Eureka is worse than average.

The Eureka E10s struggled to complete a cleaning cycle without getting stuck. It found its way onto the legs of our tables, wedged in between furniture, and managed to get itself into a position with the wheels off the ground.

As mentioned previously, it could not complete a cleaning cycle without being stuck. On one occasion, we needed to reset the robot twice in the same cycle. Additionally, the app failed to alert us on one of the nightly cleanings that it got stuck. Only after seeing it the next morning did we reset the robot.

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.

The build quality of the E10s is much like other mid-range priced robot vacuums. Both the robot and the base station are constructed out of plastic.

Part	Build Quality
Overall	Exceptional
Body	Excellent
Dustbin	Exceptional
Display / Controls	Excellent
Spinning Side Brush	Exceptional
Wheels	Excellent
Brush Roll	Excellent
Charging Dock	Exceptional

Something that stood out in the build quality and the design was the clear debris container. In our opinion, it is odd to have a clear debris container to see all the dirt and hair it has collected.

While it’s nice to see that it is doing its job, it does give off a dirty visual wherever the base station is.

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	39.5 dB
Gentle	64.5 dB
Quiet	65.0 dB
Standard	65.2 dB
Turbo	67.3 dB
Self Empty	73.9 dB

In our noise tests, the Eureka E10s generated 67.3 dB of noise on the max power mode. This is 1.72 dB lower than the average of 69.02 dB, based on all of our noise tests to date.

Additionally, we measured the auto-empty base station noise levels at 73.9 dB.

The Eureka E10s comes with many useful settings and customization options to operate your robot to your desires. One functionality we find that expands usability is the self-lifting mopping head to help keep mopping pads off the carpet.

Set up was easy and took no more than 5 mins to unpack and get the robot on the charging station. WARNING: Be careful when removing the robot from its box, as the cardboard packaging was flimsy.

Connecting the app to the robot was fast and simple. The app and instructions guided setup and only took a few minutes to connect and update the software of the robot.

With the app you can:

• Manage maps
• Adjust cleaning settings
• Adjust mopping settings
• Adjust cleaning sequence
• Change smart settings
• Create a custom cleaning schedule
• View cleaning history
• Manually control the robot
• Turn on do-not-disturb settings
• Alexa and Google Voice Control

One issue we did have with the app was that it failed to alert us when the robot was stuck. As previously mentioned, on one of the cleaning cycles when the robot was stuck, we received no notification and had to find the robot the next morning.

There are three control buttons on top of the robot. These buttons control:

• Home Icon – returns the robot to the station and begins charging.
• Power Icon – Turns the robot on / off and starts / stops cleaning.
• Square Icon – Starts / spot cleaning and resets the network settings to help connect the robot to its app.

In The Box

• Eureka E10s

The Eureka E10s has an estimated yearly maintenance cost of $40. The following are the major maintenance tasks for the Eureka E10s. We weren’t able to find the individual mop pods, side brushes, main brush, or filters available for purchase. However, you can buy a kit that contains all of the above and is everything you need for annual maintenance.

Task	Description	Est. Annual Cost
Mop Pad	Wash and replace as needed	$0 (2 included with annual kit)
Base Station Debris Container	Empty and clean as needed	$0

Product Evolution

Eureka E10s is the only robot vacuum Eureka currently offers that comes with a base station and a mopping feature. Eureka offers two other robots that have vacuum-only features. These are the NER650 and NER300(Groove). Both of these robots are standalone vacuums that require manual emptying and maintenance.

All robots do come with app connectivity and voice control with Google / Alexa.

What stands out on the Eureka E10s is the lackluster navigation performance. Typically robot vacuums do not have this many issues navigating around the office. However, the E10s got stuck multiple times.

Aside from the navigation performance, the debris performance was excellent and beat our current testing average. Additionally, the overall cleaning performance scored significantly higher than our testing average.
