How to Choose a Robot Vacuum Cleaner Based on Suction Power?

If you are in the market for a robot vacuum cleaner, it is essential to choose one that effectively sucks up dirt and debris. However, comparing different models can be confusing, especially when it comes to understanding data such as suction power, which directly impacts its cleaning ability. To help you make an informed decision, we've put together a guide on the basics of robot vacuum cleaner suction and offer tips on selecting the right model – after all, the cleaning needs of a Gold Coast mansion and a Sydney apartment vary. We'll even recommend some models available in Australia with exceptional suction. Don't miss out on our guide if you're considering purchasing a robot vacuum cleaner!

What Is “Pa” When Referring To The Suction Of A Robot Vacuum?

"Pa" is an abbreviation of Pascal, the unit used to measure suction, which commonly refers to the "vacuum level", the force required to lift objects. Today, suction power in an auto vacuum typically range from 2,500 to 5,000 Pa. The higher the Pa value, the greater the force lifting debris off the floor. That said, a higher Pa value alone does not guarantee superior performance.

Airflow – the amount of air the vacuum cleaner can suck in – also affects suction power. Even with a high Pa value, a vacuum cleaner with zero airflow cannot effectively lift debris. Therefore, a vacuum that balances Pa and airflow can be considered to have a high suction and better performance.

What's The Average Suction Power Of Vacuum Cleaners?

The average suction power is about between 100-280 AW, but it varies by the type of vacuum cleaner and is measured in different units. Besides "Pa", you might also see suction power displayed in Watts (W) or Air Watts (AW).

Watts is the amount of electrical power consumed by the motor while cleaning. On the other hand, Air Wattis a unit that indicates the vacuum’s suction level and airflow, a more comprehensive measure of suction power.

Since Watts is measured while the vacuum is plugged in, cordless and robot vacuums will not have the same suction power displayed. Hence, it is often represented by “Pa” or “AW” instead. The unit used to display the suction power largely depends on manufacturers.

To give you a better idea, we compare the suction power of different types of vacuum cleaners in Air Watt.

What is Dust Pick-Up Rate?

The Dust Pick-Up Rate (DPU) represents the actual suction capability of a vacuum cleaner to collect dust.

The dust pickup rate is calculated by measuring the amount of debris left after vacuuming the floor, and determining the percentage of debris that was picked up. A higher DPU value indicates stronger suction power. The debris used in this test is typically "quartz sand." In countries where outdoor shoes are worn indoors, the ability of a vacuum cleaner to effectively clean sand is an important performance factor.

What is a Good Suction Power for a Robot Vacuum Cleaner?

In the world of robot vacuum cleaners, suction power over 3,000Pa is generally considered sufficient for removing household dirt and debris. Higher suction power typically means more efficient cleaning. Premium models like our DEEBOT T30 OMNI feature a remarkable 11,000Pa ¹ suction power, hence you can trust it to give your space a thorough clean, particularly on carpets.

Its mopping ability is equally impressive, with the OZMO Turbo applying constant pressure on the spinning mop for scrubbing, while the upgraded rubber brush with spiralling blades effectively removes dirt and dust from floor crevices and carpets. For those with carpets at home, you’ll be glad to know that Auto-mop Lifting cleans smoothly between hard floors and carpets while keeping your carpet dry.

What Are The Key Factors Affecting Suction Power In Vacuums?

Many vacuum cleaners display their suction in terms of "suction power," but suction can be influenced by factors other than pascals and watts. In particular, the performance of the brush head has a significant impact on suction power. Suction power is measured with the head removed, but the actual "cleanliness of the floor" also depends on its ability to collect dirt (collection power).

There are mainly three types of brush heads, and their collection power and strengths vary.

Floor brushes can be purchased inexpensively, but their collection power is weak, so it would be best to avoid them if you want to thoroughly clean your floors. Additionally, there are differences in the sustained suction power between bagged and bagless (cyclonic) types. Cyclonic types have less of a drop in suction power, while bagged types are more prone to a drop in suction power due to clogging. However, the suction power will return once the bag is replaced.

What to Consider When Choosing a Robot Vacuum With Best Suction?

When shopping for the right robotic vacuum cleaner with high suction for your home, consider factors that impact suction power, such as airflow design, brushes, and filtration systems. Furthermore, assessing your cleaning needs in terms of floor type, pets, and allergies will help you find the right robot vacuum.

● Suction Power: The higher the suction power, the stronger the cleaning performance. Standard robotic vacuums typically have 2,500-5,000 Pa or a dust pickup rate of 95% or more, with advanced models like the DEEBOT T30 OMNI featuring 11,000Pa suction power.

● Airflow Design: Suction power is also heavily influenced by their internal airflow dynamics, and optimal designs reduce air resistance while maintaining suction force. Streamlined design support and strengthen consistent and powerful suction performance.

● Brushes: In an automatic vacuum, brushes like rollers and side brushes help loosen up debris for vacuuming. Check the material of the brushes, as they should be soft to prevent damage to the floors while efficiently collecting particles.

● Filters: For those suffering from allergies or with pets at home, a good filtration system such as HEPA filters can effectively capture debris and keep them trappedinside the vacuum without releasing them back into the air. Regular cleaning helps prevent clogs in the filters, which can reduce suction power over time.

● Floor Type: Different floor types have their own cleaning needs. For example, carpets typically have long fibres that require more suction power to clean. It is common to have various floor types at home, so select a vacuum that can fit your cleaning needs.

● Pets & Allergies: For pet owners and allergy sufferers, smart vacuums with strong suction power tackle pet hair and allergens. Schedule regular cleaning sessions or activate a session whenever you like via remote control.

Tips for Maintaining Maximum Suction Of Your Robot Vacuums

Keeping your vacuum performing at its best requires regular maintenance. Even with hands-free features like a self-emptying dock station, it's still important to clean and maintain your auto vacuum periodically to prevent suction power loss.

First, regularly empty the dustbin and clean the filters to prevent clogs that can reduce suction power. Then, check and clean the brushes and rollers to remove tangled hair and debris. Use a dry, soft cloth to wipe the sensors to keep them clean for optimal navigation. If you have a vacuum and mop combo, inspect the mop pads regularly to avoid any bacteria and odour issues.
