Dyson vs. Roomba: Which is the Better Vacuum Option?

If you are shopping for an autonomous vacuum cleaner, you’ve probably heard of the two high-end brands, Dyson and Roomba. These two are among the leading names in the autonomous vacuum industry, providing top-notch cleaning solutions. 

Today, iRobot’s Roomba products are renowned for their ability to clean and vacuum homes with minimal human intervention while disposing of dirt, dust, and grime. These intelligent robots can navigate through a home and define no-go areas. Besides, Dyson manufactures vacuum cleaners in various categories, including cordless, upright, and canister vacuums.

So, which is the better vacuum option? Below, we highlight key similarities and differences between the two robotic vacuum brands. Let’s dive into them.

Dyson vs. Roomba: What’s the Difference?

Both brands are designed with thoughtful intelligence to tackle tough messes on your floors and integrate seamlessly into your home. However, as innovative as these two brands of vacuums can be, they differ in several key aspects. Let’s break them down below.



iRobot’s Roomba only focuses on making cordless automated vacuum cleaners. In contrast, Dyson manufactures and sells vacuum cleaners across several categories, from stick to handheld, robotic, upright, and wall-mounted vacuums. The company also manufactures other products, such as air purifiers, hair dryers, hair stylers, and humidifiers.


Roomba vacuums use the iAdapt® 1.0 Navigation Technology that allows them to navigate the surface with the help of a responsive algorithm. The more they clean a room, the smarter the vacuum becomes. They also have four sensors on the bumper that allow for efficient room mapping and cleaning. These sensors constantly send infrared signals to the floor surface, expecting them to be bounced back, and if no signal is received, the vacuum avoids that direction. Additionally, wall sensors enable the vacuum to detect walls and clean along their parameters instead of retreating. On the other hand, cliff sensors prevent the vacuum from falling down stairs or balconies. 

Dyson robot vacuum cleaners use advanced navigation computer mechanics that integrate complex probability theory, mathematics, geometry, and trigonometry to map a room. The 360° vision system allows the vacuum to understand and interpret its surroundings. Their ability to map individual rooms and adjust their settings makes Roomba vacuums stand out. The 3D sensors allow the vacuums to avoid obstacles at least 2.5 cm away.

Generally, Dyson vacuums are more expensive than Roomba. For example, the Dyson 360 eye mid-range vacuum costs about the same price as Roomba’s top model, the S9+. Roomba also has cheaper automated vacuum cleaner options like the Roomba 675, which retails at about $241. The features of these low-priced vacuum cleaners are lacking compared to the high-priced Roomba models. If you are on a tight budget, Roomba has got you covered. Besides, if you need a vacuum cleaner by Dyson that’s in the price range of cheaper Roomba vacuums, you’ll have to settle for a regular vacuum cleaner, not a robot.

Roomba manufactures vacuum models that use standard and HEPA filters, while Dyson vacuums use pre-motor filters that make the vacuums ideal for pet owners. It is worth noting that some Dyson vacuums are compatible with HEPA filters, such as the Dyson V15 Detect Absolute cordless vacuum.

HEPA filters are more efficient as they can capture particles of up to 0.3 microns. While the vacuum cleans your floors, your air quality improves significantly as the filter captures 99.97 percent of particles from the air, including animal dander, dust, smoke, mold, and other allergens. Therefore, we recommend getting a vacuum with HEPA filters, especially if you have a child or pet at home.

  • Laser reveals microscopic dust
  • Optimizes suction and run time based on dust level and floor type
  • Piezo sensor

Roomba launched its first robot vacuum in 2002, which gave it a head start. Therefore, there are more vacuum models under Roomba than under Dyson. Some of Roomba’s available vacuums include Roomba j7 Robot, Roomba i4 Robot Vacuum, Roomba i3+ EVO, and Roomba S9+. 

On the other hand, Dyson automated vacuums include Dyson 360 Heuristic and Dyson 360 eye. However, it is said that Dyson plans to launch a new robovac model soon.
