December 28, 2023

Having a robot vacuum with strong suction performance is essential for effective cleaning. A robot vacuum’s suction power determines how much dirt, dust, and debris it can pick up from your floors. This means that if you want to keep your home clean, you need to find a robot vacuum with the strongest suction possible.

In this article, we will compare some most famous robot vacuums in terms of suction power and what features should be considered when choosing a robot vacuum.

How to Measure Suction Power in Robot Vacuums

When shopping for a robot vacuum cleaner, it is important to understand the potential of its suction power. There is no rule as to the location where the converted suction value is taken by any measuring device or method of measurement. The highest value is measured directly on the engine, but the suction value can decrease on the way to the intake manifold if there is a leak in the air duct or the design of the air duct is straight or round.

As such, you should always exercise caution when examining recommended values from unknown manufacturers who may use them as advertising tactics.

Ultimately though, a suction force of 1000 Pa or more serves as the general rule-of-thumb benchmark for quality vacuuming performance.

I did my research to compare the suction power of current vacuum cleaners, from robot vacuums to regular vacuums. Here’s what I’ve found out.

  • Robot vacuum cleaners operating in the range from 2000 to 5000 Pa
  • Cordless vacuum cleaners from 10,000 to 20,000 Pa
  • Household vacuum cleaners (mains powered) available from 13,000 to 25,000 Pa

The robot vacuum cleaner has the strongest suction power of 5000 Pa as of today, but it doesn’t mean it can clean better than the ones with suction power of 2000, or 3000 Pa. As there is no standard on how to measure the suction force, so this is just an estimate from the manufacturers to make it easier for customers to choose.

I wrote an article to compare the differences between robot vacuums, and how to select the suction power based on your floor space, make sure you check it out here.

Factors Affecting Suction Performance

There are a few external factors that can affect a robot vacuum’s suction performance, such as battery life, clogged filters, and even home layout and furniture.

Battery life & clogged filters

When it comes to battery life, robot vacuums usually have a limited amount of time they can run before needing to recharge, which in turn affects their cleaning power. If the robot is running low on battery, it will reduce its suction power in order to conserve energy.

Clogged filters can also decrease suction performance as they restrict airflow.


Lastly, a robot’s ability to clean effectively is heavily reliant on the layout of a home and any furniture or obstacles in its way. If furniture and obstacles are blocking the robot’s path, this can reduce its suction power as it has to work harder to clean around them.

All these factors should be taken into consideration when looking at a robot vacuum’s overall cleaning performance.

Regular care

To maintain optimal suction power over time, it is important to regularly clean and replace robot vacuum filters.

Additionally, robot vacuums should be emptied after each use to prevent clogs which can restrict airflow and reduce suction power.

It is also helpful to keep furniture out of the robot’s way as this will allow it to move freely and maximize its cleaning efficiency.

Lastly, maintaining a regular charging schedule for your robot vacuum ensures that its battery life remains strong so that it can consistently perform at peak levels. Following these simple tips will help ensure your robot vacuum maintains optimal suction performance over time!


When selecting a robot vacuum, suction performance is an important factor to consider. The amount of suction power that robot vacuums offer can range widely, depending on the model and brand.
