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.
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.
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.
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.
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.
The Shark ION Robot isn't designed for use on stairs.
The Shark ION Robot isn't designed to clean car interiors.
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.
This vacuum has many parts that need regular cleaning, though, thankfully, they're easy 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. However, like the Shark IQ Robot, 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 its remaining battery life and the 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. 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.
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 has 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 bulky and small debris, like cereal or rice, without difficulty. However, it has a very hard time dealing with pet hair on this surface type.
The Shark ION Robot Vacuum performs badly on low-pile carpet. Pet hair can get stuck in its brushroll rather than being sucked into its dustbin, and it picks up very little in the way of fine material like baking soda. However, it's reasonably effective in dealing 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, 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.
The Shark AV752 ION Robot Vacuum has a reasonably broad selection of automation features. Its SharkClean companion app allows you to manually stop and start a cleaning job, 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's incapable of mapping out its coverage area, so you can't set up virtual boundary lines or schedule cleaning sessions for specific rooms.
The Shark ION Robot comes in three color variants: 'White', 'Gray', and 'Black'. We tested the 'White' variant, and you can see its label here. The model numbers and corresponding colors are listed below.
If you come across a different variant, let us know in the discussions, and we'll update our review.
