The Shark ION Robot 2020 is a budget-friendly robot vacuum. It has superb battery life, a sturdy-feeling construction, and good performance on bare floors. Unfortunately, it struggles quite a bit on low-pile carpet and does an only mediocre job of sucking up debris on high-pile carpet. It also doesn't have a HEPA filter to trap allergens and can have an especially hard time with pet hair, which can get trapped in its brushroll.
The Shark ION Robot Vacuum is poor for dealing with messes on low-pile carpet. Pet hair can become trapped in its brushroll, and it sucks up very little fine debris, such as baking soda. It also incurs high recurring costs and can be difficult to maintain. Thankfully, it offers outstanding battery performance and feels well-built.
The Shark ION Robot Vacuum is a passable choice for high-pile carpets. It struggles with pet hair and fine debris like baking soda and does a passable job when it comes to larger sand-like material. Many parts require regular servicing or replacement, so recurring costs are quite high. That said, it has sufficient battery life for long cleaning tasks and feels quite sturdy overall.
The Shark ION Robot Vacuum is a bad option for cleaning up pet hair. Pet hair can get caught in its brushroll instead of being picked up, especially on carpeted surfaces. It's demanding in terms of maintenance and has high recurring costs. It also doesn't have a HEPA filter to trap allergens as it cleans, which could be a nuisance if you have a heavily-shedding pet.
The Shark ION Robot Vacuum isn't designed to be used on stairs.
The Shark ION Robot Vacuum isn't designed to clean car interiors.
The Shark ION Robot Vacuum is well-built. It has a primarily hard matte-finish plastic construction, 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. Setup is a fairly simple process, requiring only that you snap the two included side brushes into place and plug in its dock station.
The Shark ION Robot can be difficult to maintain due to the high number of parts that require regular servicing, though they're fairly simple to access.
The Shark ION Robot Vacuum has many recurring costs.
You can purchase any one of these parts, as well as additional accessories, on Shark's website.
The Shark ION Robot has outstanding storing capabilities. It has a small, compact body along with a low-profile charging dock.
The Shark ION Robot has an acceptably-sized dust bin. Like the Shark IQ Robot's dirt compartment, it doesn't have a max fill sensor to let you know once it has reached peak capacity.
The Shark ION Robot's range is limited only by remaining battery life and room left in its dirt compartment. Unfortunately, it can't climb or descend stairs.
The Shark ION Robot Vacuum is very portable. It doesn't weigh very much, but it lacks a carrying handle to make it easier to move around.
The Shark ION Robot has superb battery performance. Battery life doesn't vary significantly between its high-efficiency 'Eco' and high-suction 'Max' mode, as it should provide roughly anywhere between 170 to over 180 minutes of continuous runtime. 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.
This vacuum has a couple of quality of life features. You can swap between three power modes through its companion app: the energy-efficient 'Eco' mode, the default 'Normal' mode, and the high-suction 'Max' mode. Physical buttons on top of the vacuum allow you to select only the 'Max' or 'Normal' modes.
The Shark ION Robot Vacuum is equipped with two side brushes that direct debris from the outer edges of the vacuum's path toward its main brushroll.
The Shark ION Robot has good performance on bare floors. It clears both bulky and small debris, like cereal or rice, without difficulty. However, it struggles a lot with pet hair, and it may take several extra passes to fully suck up this kind of debris.
The Shark ION Robot's performance on low-pile carpet is bad. Pet hair can get stuck in its brushroll, and it picks up very little in the way of fine material like baking soda. That said, it does a little better with larger debris like sand.
This vacuum delivers mediocre performance on high-pile carpet. Pet hair can get stuck in its brushroll, and it picks up little in the way of small, fine debris like baking soda. It may also take an extra pass to clean up larger sand-like material.
The Shark ION Robot is reasonably maneuverable. It uses random pathing to plot cleaning routes, so 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.
The Shark ION Robot Vacuum has a reasonably broad selection of automation features. Its SharkClean companion app allows you to manually stop and start cleaning, change its power mode, send it back to its charging dock, and check previous cleaning history as well as remaining battery life. You can also enable voice control functions via Google Home or Amazon Alexa devices. Unfortunately, unlike the Shark IQ Robot, it lacks any sort of boundary function, so you can't block it out of certain areas.
The Shark ION Robot Vacuum comes in two color variants: 'White' and 'Black'. We tested the 'White' variant, and you can see its label here.

The Shark ION Robot is a simple, budget-priced 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.

The Shark IQ Robot is a better option for most use cases 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.
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.
The iRobot Roomba E5 and Shark ION Robot 2020 each have their own 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, more automation features, and superior overall performance on bare floors.
The eufy RoboVac 11S and Shark ION Robot 2020 each have their own distinct advantages, and one may suit you better than the other depending on your needs.
