Shark Ion Robot vs Roomba Comparison

robot vacuum cleaner comparison between shark ion robot vs roomba

If you are currently doing a Shark Ion Robot vs. Roomba comparison, then you must have gotten tired of using an upright vacuum. We can’t blame you. We hate vacuuming, too, and we hate how time-consuming it is.

The truth is, most people would probably never do a Shark Ion Robot vs. Roomba comparison. For me, Roomba is the first robot vacuum brand that comes to mind when someone mentions robot vacuums. However, the Shark Ion Robot comes from Shark Ninja, which dominates the upright vacuum market in the United States. A Shark Ion Robot vs. Roomba brand comparison is essentially a head-to-head battle between the top upright vacuum and top robot vacuum brands. But, who knows, Shark Ninja may prove worthy of competing against iRobot in the robot vacuum category.

Perhaps you’d discover that Shark Ninja might have successfully used its experience in making upright vacuums and apply it to their line of autonomous cleaners. On the other hand, a Shark Ion Robot vs. Roomba comparison might solidify the latter’s dominance in the robot vacuum space. Nevertheless, a comparison between the two brands will help you decide which one to get.

Shark Ion Robot Vacuum

Shark Ninja first entered the already crowded robot vacuum market in September 2017. However, it still made an impact because of its lower prices and performance. Additionally, people already knew Shark because of its upright vacuum business.

Technologies and features shared by all Shark Ion robot vacuums

Here are some of the features that are shared by Shark robot vacuums.

Cleaning system

Shark Ion robot vacuums have three components that work together to give your floors a thorough clean. First is the main brush roll that loosens and sweeps up dirt and debris. They also have a pair of edge brushes that can take care of the dust hiding at the corners and edges of your walls or furniture.All of these brushes will put whatever they sweep up into the robot’s cleaning path. The powerful suction will then send all of the dirt into the dustbin. Shark Ion robot products also use a non-washable filter.


While brushes are notorious for getting tangled, the Shark Ion robot vacuums have a self-cleaning technology that keeps the brushes clean. As a result, the robot vacuum chokes less on hair, fiber, or string.

Sensor-based navigation

All Shark Ion robot vacuum models use a variety of sensors that allow the robot to move around your floors, comprehensively covering all areas. These sensors also allow the robot vacuum to avoid bumping into furniture, walls, and other obstacles. They also help prevent steep falls.

BotBoundary strips

The BotBoundary strips prevent your Shark Ion robot vacuum from entering areas that you do not want it to clean. You can also use this to keep the robot inside a particular room.


When its lithium-ion battery runs low on juice, the Shark Ion robot vacuum will automatically go back to the charging dock.

Remote control

You have a way to control your Shark Ion robot vacuum remotely, so you no longer need to bend down to operate it. For older models, the manufacturer included a physical remote that you can use to start, pause, or stop a cleaning session. You can also use this remote control to set schedules for the robot vacuum.For later models, the manufacturer introduced Wi-Fi connectivity and voice commands. You can now remotely control your robot vacuum using a companion mobile app or with a smart speaker such as Amazon Alexa.

All Roombas now have two multi-surface brushes to replace previous bristle brushes and the debris extractor.The multi-surface brushes do not have bristles, which lessen the probability of pet and human hair getting tangled in it. These brushes make Roombas more compatible for pet hair than other robot vacuums with bristle brushes.
