The Shark EZ Robot Self-Empty is a mid-range robot vacuum that comes bundled with a self-emptying base station, letting it automatically dump debris from its internal dustbin into an external dirt compartment for easier maintenance. Compared to the pricier Shark AI Ultra Robot, which also has an automatic base station, it lacks a LIDAR mapping sensor, resulting in less precise navigation and a more limited set of automation capabilities. Otherwise, its debris-pickup performance is similar.

Our Verdict

7.1
Bare Floor 

The Shark EZ Robot vacuum is decent for bare floors. It clears pet hair and small debris without issue, though it struggles somewhat with bulky material. It feels well-built, has a long battery life, and offers a fairly wide range of automation features, including its self-emptying dustbin. Unfortunately, many parts need regular cleaning. Recurring costs are also high, with many components needing periodic replacement. Also, while it can do a good job of maneuvering itself, it generally won't climb over obstacles like power cables and may treat them as solid barriers rather than low obstacles.

Pros
  • Fantastic pet hair cleaning performance on bare floors.
  • Automatically empties dirt compartment into large external dustbin.
  • Long battery life.
Cons
  • High recurring costs.
  • Many parts need regular cleaning.
  • No mopping feature.
6.1
Low-Pile Carpet 

The Shark EZ Robot vacuum is mediocre for cleaning low-pile carpets. It'll take a couple of passes for this vacuum to clear away solid debris as well as pet hair from this surface type. While it feels sturdily built, it's demanding in regular maintenance requirements, with many parts needing regular cleaning. Recurring costs are also high since many components need periodic replacing, too.

Pros
  • Automatically empties dirt compartment into large external dustbin.
  • Long battery life.
  • Good build quality.
Cons
  • High recurring costs.
  • Many parts need regular cleaning.
  • Poor overall debris pickup on low-pile carpet.
6.2
High-Pile Carpet 

The Shark EZ Robot Self-Empty is a passable choice for cleaning high-pile carpet. It doesn't have any trouble maneuvering on this surface type, though rug tassels can occasionally get caught in its brushroll. While it has a hard time with fine debris embedded in carpet fibers, it's fairly capable when dealing with larger debris and pet hair. It has a broad range of automation features, including its self-emptying function. However, many parts need regular cleaning or replacing, so recurring costs are high.

Pros
  • Automatically empties dirt compartment into large external dustbin.
  • Long battery life.
Cons
  • High recurring costs.
  • Many parts need regular cleaning.
4.8
Pets 

The Shark EZ Robot Self-Empty isn't the best option for pet owners. It does a great job of handling pet hair on floors but struggles with hair on carpeted surfaces. It's demanding in regular maintenance and has high recurring costs too. It also lacks a HEPA filter to trap allergens as it cleans, and there's no mopping system to scrub away stains. Thankfully, its brushroll is removable, making it easier to remove any tangled hair wraps. It doesn't make much noise, which is good if your pet is sensitive to loud noises.

Pros
  • Fantastic pet hair cleaning performance on bare floors.
  • Removable brushroll.
Cons
  • High recurring costs.
  • Many parts need regular cleaning.
  • No HEPA filter.
  • No mopping feature.

    Popular Robot Vacuum Comparisons

    The Shark EZ Robot Self-Empty is a fairly versatile robot vacuum. Like the i7+ variant of the iRobot Roomba i7, it has an external dustbin mounted to its docking station, so you don't need to empty the vacuum manually whenever it gets full. It differs in that its external base station doesn't use disposable dirtbags, meaning that final debris disposal isn't quite as hygienic. It delivers good performance on bare floors and does an impressive job cleaning high-pile carpets. However, it has demanding maintenance requirements and incurs high recurring costs, even by the standards of other robot vacuums.

    If you're looking for alternatives, take a look at our list of recommendations of the best robot vacuums, the best robot vacuums for carpet, and the best robot vacuums for pet hair.

    Shark AI Robot RV2001

    The Shark EZ Robot Self-Empty AV911S and the Shark AI Robot RV2001 both have advantages, meaning one may suit you better depending on your own needs. The EZ has a much greater dirt compartment capacity because of its external dustbin and delivers superior performance on low- and high-pile carpets, especially when dealing with pet hair. Meanwhile, the AI incurs fewer recurring costs, has fewer parts that need regular cleaning, and maneuvers over obstructions like electrical cords with less difficulty. In addition, you can use its companion app to set up virtual boundary lines that the AI won't cross.

    Shark IQ Robot RV1001

    The Shark EZ Robot Self-Empty AV911S is slightly better than the Shark IQ Robot RV1001. The EZ has an automatic dirt disposal feature, charges a lot faster, gets caught on rug tassels less frequently, and delivers better overall cleaning performance on low- and high-pile carpets. Conversely, the IQ incurs fewer recurring costs and is easier to maintain.

    Shark IQ Robot AV992

    The Shark EZ Robot Self-Empty AV911S is better than the Shark IQ Robot AV992. The EZ has an automatic dirt disposal function, charges slightly faster while offering similar overall battery life, and maneuvers over tasseled rugs with less difficulty. Meanwhile, the AV992 has fewer parts that need regular cleaning and incurs lower recurring costs.

    Shark ION Robot AV752

    The Shark EZ Robot Self-Empty AV911S is better than the Shark ION Robot AV752 for most uses. The EZ delivers better performance on bare floors and carpets, maneuvers itself with less difficulty, and has a broader range of automation features. Its external dustbin also gives it a larger, more effective debris capacity. However, the ION has fewer parts that need periodic replacing or maintenance and has a longer maximum battery life, though it does take notably longer to recharge than the EZ.

    The build quality is good. It's similar in design to other Shark robot vacuums, like the Shark AI Robot, with a matte-finish hard plastic body and twin drive wheels with rubber treads. Conversely, its hard plastic dirt compartment feels a little flimsy. It's easy to assemble out of the box, requiring only that you snap its two side brushes into place and place the self-emptying dock station on the included mat. The manufacturer recommends only placing the mat on carpets, as it can slip around on bare floors. Check out the Narwal Freo X Ultra if you want something that feels more robust.

    User Maintenance

    This vacuum is quite hard to maintain as it has many parts that require regular maintenance. Luckily, most parts are easy to access.

    • Dustbin: You can remove the dustbin by simply pressing the two release buttons at the back of the part and then lifting it free. The vacuum automatically dumps accumulated debris into the external dirt bin on the charging dock, but you can empty it yourself if you feel that it's necessary.
    • Dustbin filter: Cleaning the internal dustbin filter and lint screen is a bit of a hassle, as they're both held in place by Philips-head screws. You should remove any stuck-on debris by hand regularly, but make sure not to wash it under water.
    • Base station dustbin: The external dustbin releases from the base station pretty easily. Another button on the side opens a compartment door, so you can dump out any accumulated debris. According to the manufacturer, it can hold up to roughly 15 days' worth of collected debris.
    • Base station dust bin pre-motor filters: Unlike the internal filters, you can simply lift the base station filters directly from their housing. You should clean them using only cold water once a month. Make sure to let them dry for at least 24 hours before putting it back in its place.
    • Base station post-motor filter: You can find the post-motor filter in the base station behind a filter door on the base station. You should rinse it with cold water once a year. Leave it to air dry completely before reinstalling it.
    • Brushroll: You can access the brushroll by removing the brushroll cover, which is fairly easy and doesn't require any tools. That said, the brushroll is somewhat tangle-prone. You can remove any stuck-on debris or tangled hair by hand whenever necessary.
    • Side brushes: You can simply pull the two side brushes from their sockets with no need to unscrew them. Check for any accumulated debris once a week and clean them as necessary, either by hand or with a dry cloth, as they tend to collect quite a bit of debris.
    • Drive wheels: You should clear the drive wheels and their housings of any accumulated debris whenever necessary. Make sure to rotate the wheels to ensure full coverage.
    • Front wheel: You can simply pull the front wheel from its housing, but you may need another tool to get enough leverage. Remove any accumulated dust, dirt, or hair from the wheel and the socket when necessary.
    • Sensors and charging pads: You should dust the sensors and charging pads whenever you notice a buildup of debris.

    This vacuum incurs high recurring costs.

    • Pre-motor filter: There isn't a specified replacement time for this filter. That said, you can buy a replacement from Shark's website.
    • Base station dust bin pre-motor filters: You should replace this filter every two and a half years. You can buy a replacement here.
    • Base station post-motor filter: The base station's post-motor filter has an estimated service life of three years.
    • Brushroll: You should replace the brushroll every six to 12 months, depending on your usage. You can buy a replacement here.
    • Side brushes: You should replace the side brushes if bent or damaged.

    Shark also offers a 'Replacement Bundle', which includes:

    • 1x Vacuum filter

    The combined capacity of this vacuum's internal dustbin and base station dirt compartment is decently large, though it has a smaller capacity than the self-emptying base station that's compatible with the iRobot Roomba i1, which uses a higher-capacity disposable dirtbag. The external dust bin has a clear plastic window that gives you a rough estimate of how full it is.

    The battery performance is superb. In its high-power 'Max' power mode, it supplies roughly 70 minutes of cleaning time. You can stretch it to over 140 minutes if it's run in 'Eco' mode. Unfortunately, the vacuum doesn't remember the power setting it was set to on previous cleaning sessions, so you have to make that adjustment manually every time. Like the Shark AI Robot, a set of indicator lights on the top surface of the vacuum give you a rough estimate of how much charge is remaining.

    The Shark EZ Robot Self-Empty has a couple of quality-of-life features. There are three suction power modes: 'Normal', which is the default mode that you can only change once the vacuum is up and running, the more energy-efficient 'Eco' mode, and the high-power 'Max' mode. Still, unlike the Shark AI Ultra Robot, it doesn't have a LIDAR mapping system, which would help navigate in darker environments.

    Performance on bare floors is excellent. It clears away small debris like rice without any issue, but it might take another go-around to clear away bulkier debris like cereal.

    Note: Since this vacuum automatically empties its internal dirt compartment when docked after completing its job, it doesn't lose suction performance. All testing was completed when the dirt compartment was empty, with the data for the 0.25L and 0.75L tests being copied from the 0L test.

    Performance on low-pile carpet is poor. It clears most larger debris like sand but has a hard time cleaning finer debris like baking soda from this surface type. Check out the Shark Matrix Robot if you're looking for a robot vacuum that performs better on this surface type.

    Note: Since this vacuum automatically empties its internal dirt compartment when docked after completing its job, it doesn't lose suction performance. All testing was completed when the dirt compartment was empty, with the data for the 0.25L and 0.75L tests being copied from the 0L test.

    Maneuverability

    This vacuum has good maneuverability. It cleans in an efficient, organized pattern and can even return to areas that require more cleaning. It's also small enough to clean under most couches and tables. It can clean most rugs, though tassels can get caught in its brushroll on some rare occasions. Unfortunately, it struggles with low-lying obstructions like electrical cords, which the vacuum may identify as obstacles to avoid.

It can also be connected to Alexa or Google Home devices if you'd prefer to use voice commands to control the vacuum. Unfortunately, there aren't any physical boundary strips included with the vacuum that would keep it out of certain areas. The two control buttons on top of the vacuum are somewhat limited in capability, as they only allow you to start and stop a cleaning session or send the vacuum back to its dock.

    The SharkClean app is decent overall. It's fairly feature-packed but not especially intuitive to use, and it's also prone to freezing. You can use the app to change the vacuum's suction power mode, command it to clean or return to its dock, schedule cleaning sessions, check the cleaning history and charge status, update the vacuum's firmware, or enable push notifications. You'll also need a 2.4GHz Wi-Fi connection to control the vacuum via the app. Unlike the Shark AI Robot, you can't set up virtual no-go zones through the companion app.
