How to choose the best robot vacuum cleaner

Convenient, effortless, and intelligent, the advantages of a robot vacuum cleaner to help keep your home continuously clean and healthy. To achieve a deep clean every time, it’s important to opt for a model that has strong suction power.

Ahead, we walk through how to choose a robot vacuum based on your interior space and needs. The best robot vacuum lifts and removes dirt and debris across different floor types and without loss of suction. Discover the Dyson 360 Vis Nav™ and what it can do for your home.

What to look for in a robot vacuum?

  • 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 vs Air Watts: what does this mean?


Two measures of suction power – Air Watts and Pascals – are used to indicate robot vacuum quality. To help you determine how to choose a robot vacuum cleaner, let’s break down what each term means.

  • What are Pascals?

    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.

  • What are Air Watts?

    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.

Ideal performance of a robot vacuum

  • 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

Features to consider when looking for a robot vacuum

Alongside features like the ones above, the requirements of your home will help determine which robot vacuum is the best for you. Many homes include a range of floor types – like wood, tiles, laminate and carpet – and so the best robot vacuum is one that can switch seamlessly across them. The Dyson triple-action brush bar in the Dyson robot vacuum is engineered for all floors, meaning it can seamlessly vacuum for a whole-home clean.

Dyson 360 Vis Nav™ robot vacuum

  • 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.
