Suction power is like a vacuum cleaner sucking up dirt. Robot vacuums have strong suction to help them pick up dirt and dust. The debate over whether stronger suction is always better when it comes to robot vacuums is one that has been ongoing for many years. On the one hand, some people believe that more suction power will result in a more effective cleaning job and therefore be better overall. On the other hand, there are those who feel that too much suction power can be damaging to both carpets and furniture, as it can cause them to become worn or frayed over time.
Does Stronger Robot Vacuum Suction Mean Better?
In general, stronger suction power means better stronger vacuuming. However, as there is no rule on how to measure the suction power, that comparison becomes somewhat irrelevant. Therefore, when choosing a robot vacuum, you need to balance suction power and other features that a robot vacuum can offer. Ultimately, stronger isn’t necessarily better when it comes to robot vacuums.
What Does “PA” say about Robot Vacuum Suction Power

Manufacturers of vacuum cleaners use either Pascal (pA) or Air Watt (AW) units to measure the suction power, rather than Watts which is used for measuring electricity consumption. Commonly, you will come across the unit pascal when searching for information about a robot vacuum’s strength and performance capabilities. So if you are looking to select one with strong suction power, look out for higher values in pa!
The Pascal unit, or Pa for short, is used in physics to indicate the difference in pressure. This makes perfect sense when it comes to vacuum cleaners — their whole purpose is to create a vacuum and suck up dirt! The higher the Pa value of your cleaner, the more powerful its suction will be– meaning less mess left behind.
How To Measure Robot Vacuum Suction Power

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 the 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.

Pros of Strong Suction Power

Strong suction power can help robot vacuums do a much more effective job of cleaning carpets. It is also great for removing pet hair, picking up debris, and even dust particles! With robot vacuums featuring the latest technology, you can now get models that are equipped with increased suction power. This means that your robot vacuum cleaner can move through your home with ease, while still being able to pick up dirt and dust in even hard-to-reach places.
In addition, robot vacuums that boast strong suction power also offer better performance when it comes to cleaning hardwoods, tile, and other surfaces. With a robot vacuum’s increased suction power, it can ensure that the robot vacuum is able to capture more dirt and debris than a regular vacuum cleaner.
Robot vacuums with high suction power are becoming increasingly popular for many reasons. With robot vacuums featuring the latest technology, you can now enjoy powerful suction that rivals traditional, mains-powered vacuum cleaners in terms of performance. One example is the iRobot Roomba S9, which boasts a Power-Lift Suction system that delivers up to 40X more suction than other iRobot robot vacuums. This is the most powerful robot vacuum on the market today, perfect for those who want a robot cleaner with maximum cleaning power.
Cons of Strong Suction Power

Despite all the benefits that strong suction power can offer to robot vacuums, there are potential downsides as well. Firstly, robot vacuums with high suction power tend to be noisier than other robot vacuums. This can be a nuisance for homeowners who don’t want their robot vacuum to be too loud.
Secondly, strong suction power can sometimes cause robot vacuums to get stuck on surfaces, such as carpets or rugs. This is due to the robot vacuum’s powerful suction force, which can sometimes make it difficult for the robot vacuum to move freely across surfaces.
Lastly, robot vacuums with strong suction power also tend to be more expensive than robot vacuums with less powerful suction.
Finding the Right Balance: What to Consider When Choosing a Robot Vacuum

When assessing your cleaning needs and deciding on a robot vacuum suction power level, there are many factors to consider. These include the type of flooring in your home, whether or not you have pets, and any personal preferences you may have. The right robot vacuum with the right suction power can make all the difference when it comes to keeping your home clean. Therefore, understanding these factors is essential for making an informed decision about which robot vacuum to choose.
Finding a robot vacuum with customizable settings that allow you to adjust the suction strength can be a great way to get the most out of your cleaning experience. With adjustable suction power, you can make sure that your robot vacuum is able to clean more effectively and efficiently by adjusting the level of suction as needed for different types of floors and surfaces in your home. Here are some tips on finding a robot vacuum with customizable settings that let you adjust the suction power according to your needs.
Conclusion
Robot vacuums with high suction power can make all the difference when it comes to keeping your home clean. By providing powerful suction that rivals traditional, mains-powered vacuum cleaners in terms of performance, robot vacuums equipped with increased suction power allow for a more thorough cleaning experience. With robot vacuums featuring adjustable settings that let you customize the suction power, you can be sure to get the most out of your robot vacuum cleaner. That being said, robot vacuums with high suction power tend to be noisier, more expensive, and may occasionally get stuck on surfaces.
Robot vacuums with high suction power can be beneficial in certain contexts; however, they may not always be the best choice. When choosing a robot vacuum cleaner for your home, it is important to consider all of the factors involved such as personal preferences and type of flooring before making an informed decision. Additionally, finding a robot vacuum with adjustable settings that allows you to customize its suction strength will help ensure that you are able to get the most out of your cleaning experience. Ultimately, stronger isn’t necessarily better when it comes to robot vacuums. Finding the right balance between suction power and other features to get the best out of your robot vacuum.
