The Shark ION Robot 2020 is a basic, budget-friendly robot vacuum. It performs well on bare floors, feels well-built, and offers exceptional battery performance. However, it has a hard time clearing debris on low-pile carpet, delivers mediocre performance on high-pile carpet, and struggles with sucking up pet hair. It also lacks an allergen-trapping HEPA filter and has many parts that need regular cleaning.

Our Verdict

6.9 Bare Floor

The Shark ION Robot is alright for cleaning bare floors. It feels well-made and clears small and bulky material without too much of a hassle. However, it struggles noticeably with pet hair and is demanding in user maintenance. It also has somewhat rudimentary automation capabilities and a basic navigation system that could cause it to miss some parts of its coverage area.

Pros
  • Sturdy build quality.
  • Does a good job of cleaning small and bulky debris on bare floors.
  • Long battery life.
Cons
  • Poor pet hair cleaning performance.
  • Demanding in terms of user maintenance.
  • High recurring costs.
6.1 Low-Pile Carpet

The Shark ION Robot is a poor option for dealing with messes on low-pile carpet. It struggles with sucking up pet hair, which can become trapped in its brushroll, as well as fine debris on this surface type. It also incurs high recurring costs and has many parts that need regular cleaning. Its brushroll can also occasionally get trapped on rug tassels. Thankfully, it has a long battery life and feels well-built.

Pros
  • Sturdy build quality.
  • Long battery life.
Cons
  • Poor pet hair cleaning performance.
  • Struggles with fine debris.
  • Demanding in terms of user maintenance.
  • High recurring costs.
6.3 High-Pile Carpet

The Shark ION Robot Vacuum is a mediocre option for dealing with debris on high-pile carpets. It struggles with pet hair and fine debris and clears only a passable amount of larger material. Recurring costs are high, and many parts need regular cleaning. That said, it can climb onto high-pile rugs without too much difficulty, has sufficient battery life for long cleaning tasks, and feels quite sturdy overall.

Pros
  • Sturdy build quality.
  • Long battery life.
  • Can climb onto high-pile rugs without difficulty.
Cons
  • Poor pet hair cleaning performance.
  • Demanding in terms of user maintenance.
  • High recurring costs.
4.1 Pets

The Shark ION Robot Vacuum is bad for cleaning up pet hair. Pet hair can get caught in its brushroll instead of being sucked into its dustbin, especially on carpeted surfaces. It has many parts that need periodic cleaning and incurs high recurring costs. It doesn't have a HEPA filter to trap allergens as it cleans, either, which could be an issue if you suffer from serious allergies.

Pros
  • Sturdy build quality.
  • Long battery life.
Cons
  • Poor pet hair cleaning performance.
  • Demanding in terms of user maintenance.
  • High recurring costs.
  • No HEPA filter.
5.8 Stairs

Build Quality

The Shark ION Robot has good build quality. It's mainly made of hard plastic with a matte finish, though its front bumper, drive wheel treads, and swiveling front wheel are made of rubber. It feels quite sturdy overall, though its dustbin feels somewhat fragile, and it could be damaged if you drop it. You may want to consider the iRobot Roomba 692 if you're looking for a better-built alternative.

Out-of-the-box assembly is a fairly simple process, requiring only that you snap the two included side brushes into place and plug in its dock station.

User Maintenance

This vacuum has many parts that need regular cleaning, though, thankfully, they're easy to access.

  • Brushroll: You can access the brushroll by removing the brushroll compartment door and then pulling the component out. While the manufacturer doesn't specify an exact maintenance interval, you should remove any stuck-on debris or tangled hair regularly.
  • Dust bin: You can remove the dust bin by pressing the release button on the rear of the vacuum's body. You should empty it after every use. Be sure to remove any stuck-on hair from the integrated anti-tangle comb.
  • Pre-motor filter: The pre-motor filter is inside the dust bin lid and can be pulled out via its release tabs. You should clean it weekly by tapping it against the side of a garbage can to dislodge any stuck-on debris.
  • Side brushes: The side brushes can be pulled out of their socket by hand. You should check them weekly and remove any tangled hair or stuck-on debris by hand. If necessary, you can also wipe them down with a damp cloth before leaving them to air-dry completely.
  • Drive wheels: You should clean the drive wheels and their housing fairly regularly to ensure that there isn't any significant buildup of debris. Make sure that you rotate the wheels while cleaning to ensure no debris has gotten stuck around them.
  • Front wheel: The front wheel can be pulled from its socket by hand, but this can be hard, and you may find it easier to use a tool. You should clean it of stuck-on debris regularly.
  • Sensors: You should clean the vacuum's sensors periodically with a dry cloth or cleaning brush.
  • Charging pads: You should periodically clean the charging pads under the vacuum and on top of the dock station of any dust or debris with a dry cloth or cleaning brush.

Design
Recurring Cost
Bag Part Number No bag
Filter Part Number 1172FK870
HEPA Filter Part Number No HEPA Filter

The Shark ION Robot Vacuum has many recurring costs.

  • Pre-motor filter: You should replace the pre-motor filter every two months.
  • Brushroll: You should replace the brushroll every six to 12 months or whenever you observe visible wear. While this component's model number couldn't be found on the manufacturer's website, a compatible brushroll of a different color is available for purchase.
  • Side brushes: You should change the side brushes whenever you notice significant wear.
  • Front wheel: You should replace the front wheel every 12 months.

You can purchase any one of these parts, as well as additional accessories, on Shark's website.

The Shark ION Robot has superb battery performance. There isn't a significant difference in runtime between running it continuously in its energy-efficient 'Eco' suction power mode and high-suction 'Max' mode, as it should last for about three hours on a single charge regardless of your choice of setting. This exceeds the continuous runtime of just 60 minutes specified in the vacuum's user guide. The three indicator lights quickly let you know how much battery life is left since they gradually turn off as the charge level drops.

Maneuverability

The Shark ION Robot is reasonably maneuverable. It uses random pathing to plot cleaning routes, meaning it does occasionally miss some areas or go over the same spot more than once. Thankfully, it's small enough to easily clean under low-lying furniture like tables or couches, and it can climb onto high-pile rugs without too much difficulty, though it can get caught on rug tassels. If you want a vacuum that does a better job of maneuvering itself, consider the iRobot Roomba 614.

Compared To Other Vacuums

The Shark ION Robot is a simple budget robot vacuum. It feels well-made, and its long battery life should allow it to clean large areas without needing to be recharged. It performs best on bare floors but can have some trouble with messes on low-pile carpet or with cleaning up pet hair. Its range of automation features is more basic than those of pricier Shark robot vacuums like the Shark AI Robot.

If you're considering an alternative, take a look at our list of recommendations of the best robot vacuums for hardwood floors, the best budget robot vacuum cleaners, and the best robot vacuums for carpet.

iRobot Roomba i3+ EVO

The iRobot Roomba i3+ EVO is better than the Shark ION Robot 2020. The iRobot feels better-built, has fewer parts requiring regular maintenance, comes with an allergen-trapping HEPA filter, maneuvers itself more effectively, and performs better on all surface types. It also has a far more advanced suite of automation features, most notably its self-emptying feature, which allows it to dump any accumulated debris into a larger dirtbin built onto its charging dock. It's also capable of resuming an in-progress cleaning session after returning to its dock to recharge. Conversely, the Shark is easier to store, incurs lower recurring costs, and has a much longer battery life, though the iRobot charges a lot faster.

Shark EZ Robot Self-Empty AV911S

The Shark EZ Robot Self-Empty AV911S is better than the Shark ION Robot 2020 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.

Shark IQ Robot RV1001

The Shark IQ Robot RV1001 is a better option for most uses than the Shark ION Robot 2020. The IQ clears debris more effectively on all surface types, uses smart-pathing to plot more efficient cleaning routes, and comes with boundary makers to prevent it from moving into certain areas. Meanwhile, the ION has a much longer battery life while taking less time to recharge.

iRobot Roomba 694

The iRobot Roomba 694 is slightly better than the Shark ION Robot 2020. The iRobot has fewer parts that need regular cleaning, incurs lower recurring costs, charges substantially faster, has an automatic surface-type adjustment function, and offers superior maneuverability. However, the Shark has a slightly larger dustbin.

iRobot Roomba 692

The iRobot Roomba 692 and Shark ION Robot 2020 each have advantages, so one may suit you better than the other depending on your needs. The iRobot is better-made, easier to maintain, incurs fewer recurring costs, and charges much faster. Both vacuums deliver good performance on bare floors, though the iRobot is also a little more maneuverable. That said, the Shark struggles much less on carpeted surfaces and clears significantly more pet hair. It also has longer overall battery life, not to mention a bigger dirt compartment.

eufy RoboVac 11S

The eufy RoboVac 11S and Shark ION Robot 2020 each have distinct advantages, and one may suit you better than the other, depending on your needs. The eufy clears pet hair more effectively on all surface types and struggles less on low-pile carpet. Meanwhile, the Shark is better-built, has a longer battery life, and does a much better job of dealing with bulkier debris like cereal. It also has a companion app, though it's somewhat limited in features and isn't especially intuitive.

eufy RoboVac 30C

The Shark ION Robot 2020 is better than the eufy RoboVac 30C. The Shark feels better built, has a longer battery life, and performs better on bare floors as well as low and high-pile carpet. Meanwhile, the eufy does come with a remote control that allows you to use it without an internet connection.

Roborock E4

The Roborock E4 is a far more versatile robot vacuum than the Shark ION Robot 2020. The Roborock feels better-built, is easier to maintain, maneuvers around obstructions more easily, and has lower recurring costs, not to mention a broader suite of automation features and a larger dust bin. It also offers superior cleaning performance on all surface types. Conversely, the Shark is a little lighter and more compact.

ILIFE A4s Pro

The Shark ION Robot 2020 is slightly superior to the ILIFE A4s Pro. The Shark feels better-made, has a much longer battery life, and is more effective on bare floors and high-pile carpet, though it struggles more with pet hair than the ILIFE. The ILIFE is slightly smaller and lighter and does a marginally better job removing fine debris like baking soda from low-pile carpets.

iRobot Roomba E5

The iRobot Roomba E5 and Shark ION Robot 2020 each have advantages, and one may suit you better than the other, depending on your needs. The iRobot is better-built, easier to maintain, more maneuverable, and struggles noticeably less on low-pile carpet, especially in regards to pet hair. Conversely, while it charges much faster than the Shark, it has much shorter battery life. The Shark also has a larger dirt compartment and superior performance on bare floors.
