Robot Vacuum Suction Power Chart: How Pa Ratings Compare
If you're comparing robot vacuums, you've probably considered their suction power, or how much lifting force the vacuum has. But what does a 13,000 Pa or 35,000 Pa suction power actually mean in practice?
Below, you'll find a suction power comparison chart of Dreame's robot vacuums, what those Pa ratings look like in real life, how much suction you actually need, and other important features to consider besides how many Pa.
What Does Pa Mean on a Robot Vacuum?
Pa, short for Pascals, measures the suction pressure a robot vacuum creates. It measures the vacuum's lifting power.
Higher Pa usually means stronger suction, which helps lift dust, dirt, and pet hair embedded in your carpets. On hard floors, though, you don't always need the highest number. Everyday dust comes up much more easily, so even lower Pa ratings can do the job well.
The right suction rating depends on the type of floors you have. If you'd like to know more about suction power and what a good rating is across different types of vacuums, check out this guide on good suction power for a vacuum cleaner.
Important: Pa measures suction pressure, not airflow. It's the easiest way to compare robot vacuums side by side, though it's not the only rating that counts.

The next section walks through which Pa range makes sense for different floor types. The best choice for you is the Pa that fits your home, not the one with the biggest Pa.
Dreame Take: Dreame offers suction power from 13,000Pa to 35,000Pa because every home needs different levels of cleaning performance. The X60 Ultra sits at the top with 35,000Pa, but that doesn't automatically make it the best fit for your home. In some cases, a lower Pa rating is enough.
How Much Suction Power Do You Actually Need?
The suction power you need depends on your floors. For example, hard floors don't need as much suction power as carpeted floors. Look for the Pa that suits your floors. Here's a guide to help you out:
Your floors
Suction to look for
Hard floors, light daily dust
13,000–19,500 Pa
Mixed floors with low-pile carpet
20,000–25,000 Pa
Pet hair and medium-pile carpet
30,000 Pa
Thick or deep carpet
35,000 Pa
For homes with pets, consider pairing a high Pa with an anti-tangle brush. Strong suction helps lift hair, while the brush helps keep it from wrapping around the roller. If you're tired of daily battles with sweeping and vacuuming, see our guide to robot vacuums for pet hair for must-have features.
Pro-tip: Higher suction is especially important in homes with carpets and shedding pets. To compare models feature by feature, our robot vacuum comparison tool is a good place to start.
Other Features That Matter Besides Suction Power When Choosing a Robot Vacuum
When matching a robot vacuum to your floor type, don't focus just on the Pa rating. To get the full picture of its performance, also consider airflow, how well the vacuum seals against carpets, brush agitation, downforce, and pick-up rate.
Airflow refers to how well the vacuum gets dust and debris through the hose, wand, and into the bin. A good seal keeps suction concentrated on the floor and prevents it from escaping around the edges. Brush agitation and downforce measure how well the vacuum can free dirt and hair embedded in carpets.
Together with suction, they determine the robot vacuum's pick-up rate, or how much dirt it actually removes from the floor in one pass.
That's why Dreame looks beyond Pa alone. All these elements get engineered together, from the brush and seal through to the airflow and motor, so real pickup holds up beyond what the Pa figure alone would suggest.
Pro-tip: Suction naturally drops as the dustbin fills and the filter clogs. You need to empty the bin and clean the filter regularly to get your vacuum to perform closer to its rated suction. If your robot vacuum doesn't clean as well as it used to, check out this guide on why the vacuum loses suction for solutions to the most common issues and a quick diagnostic test that will instantly tell you which half of the vacuum has the problem.
Choose the Suction Power Fits Your Cleaning Needs
The best suction rating is the one that matches your floors, not the biggest figure on a chart. Hard floors don't need as much suction, while homes with carpets and pets can benefit from a little more.

FAQs
What is a good suction power for a robot vacuum?
It depends on the type of flooring you have. For hard floors and light pet hair, 13,000Pa to 19,500Pa is usually plenty. If your home has carpets or you have pets that shed a lot, 30,000Pa or higher may work better.
Is a higher Pa always better?
No. Besides suction (Pa), brush design, airflow, and how well the vacuum seals against the floor also affect how much dirt a robot vacuum picks up in one pass. Higher suction also tends to be noisier and drains battery faster. Choose a model that matches your floor and unique needs.
How much suction do I need for pet hair?
Choose a higher Pa rating and pair it with an anti-tangle brush. Strong suction helps lift hair, while the brush helps keep pet hair from wrapping around the roller.
Which robot vacuum has the highest suction?
The X60 Ultra and X60 Max Ultra Complete both offer 35,000Pa Vormax™ Suction that lifts dust, crumbs, pet hair, and more, making them the highest-suction models in Dreame's full range of robot vacuums.
How is the robot vacuum suction measured?
In Pascal (Pa). This refers to the pressure the motor generates.
