How to choose the best robot vacuum cleaner

To clean floor types without being manually guided, robot vacuums require specific technology. Understanding which robot vacuum cleaner is the best for your home depends on the details of your interior space (such as if you have carpeted or hard flooring), but some features are essential for all homes.

Filtration technology

All Dyson vacuum cleaners use filtration to separate and trap particles and impurities. Where unfiltered models struggle to maintain suction power and remove debris from the floor, the best robot vacuum features different filtration levels. This allows the machine to trap different particle sizes and types found in indoor spaces.

Sensors

Without being guided, how do robot vacuums work? Robot vacuums are typically designed with sensors, which enable them to detect the edges of a room, obstacles like furniture, and in some cases different floor types. To develop the best robot vacuum sensor technology, Dyson’s engineers created intelligent and independent mapping and analysis capability.

Suction

Dust and debris in homes can range in size and type, which can place pressure on vacuums. Human and pet hair, pet dander, dust, and food waste for example can block and interrupt some robot vacuums which do not have powerful motor and suction systems.

Pascals (Pa) measure the difference between the pressure inside and outside an object. Some robot vacuums have a small inlet underneath where the dust goes after it’s captured. A small inlet means a smaller airway, which means pressure increases, giving a high Pa count.

Air Watts (AW) are a measure of the suction power of a machine. The measurement takes into account both pressure (Pa) and the rate of airflow going through the robot. An Air Watts number can only be high if both pressure and airflow are high, which translates into powerful suction.

In robot vacuums, small inlets can cause high pascal pressures, but high pressure doesn’t mean high suction power. Small inlets can make it more difficult to suck up dust without getting blocked. This can result in inefficient cleaning.

In a robot with high Air Watts, the inlet that captures dust and dirt is usually wider and larger, allowing more airflow. The advantages of a robot vacuum cleaner with greater airflow allows more dust and debris to be picked up from carpets and hard floors easily.

Dyson uses Air Watts, not Pascals, to measure vacuum performance. The Dyson 360 Vis Nav™ has 65AW of suction power – six times more than the closest competitor.¹ This means it genuinely sucks up more debris and dust than any other robot vacuum across all floor types for a true, deep clean.²

Besides power, the Dyson 360 Vis Nav™ robot vacuum achieves cleaning precision, ensuring your whole home is covered. The Dyson 360 Vis Nav™ robot vacuum has a side actuator which activates every time it senses an edge or corner to reach out and clean up dust where others can’t.

The machine has also been designed with 360° vision, to intelligently map rooms for a thorough clean. With its whole-machine, fully-sealed HEPA filtration, you can be assured that what goes inside, stays inside³.

Plus, with MyDyson™ app compatibility and full connectivity to smart home systems, you can program it to clean wherever you want in your home, whenever you want.
