How to Compare Vacuum Suction Power Accurately?

Vacuum power is usually measured in Pa (Pascals), AW (Air Watts), or sometimes Water Lift. These numbers can help you compare how strong a vacuum is—but they’re not always used the same way by every brand.

• Pa (Pascals): Shows suction pressure—higher means stronger pull.

• AW (Air Watts): Combines suction and airflow—more accurate for performance.

• Water Lift: Often used for carpet vacuums—measures vertical lifting force.

Not sure what these mean or how they compare? See our full suction unit guide here.

Instead of chasing numbers, think about what surfaces you clean and how often. A vacuum that matches your real-world needs will always outperform one that just looks strong on paper.

Does Higher Wattage Mean Better Suction?

No, higher wattage does not always mean better suction. Wattage measures the power consumption of the vacuum, not its actual suction strength.

The key factors for suction strength are Pa (Pascal) and Air Watts (AW). A vacuum with high wattage may still perform poorly if it lacks strong suction in these areas.

Other factors, like motor design, airflow efficiency, and the vacuum's sealing system, also affect suction. 

What Is Good Suction Power for a Vacuum?

Good suction power depends on the type of cleaning you need. 

A vacuum typically ranges between 5,000 Pa and 20,000 Pa, depending on the surface being cleaned. For hard floors and low-pile carpets, suction power like 5,000 Pa is usually sufficient. For high-pile carpets or tougher cleaning tasks, vacuums with suction power of 8,000 Pa or higher are recommended.

Typical Suction Power Ranges 

• Robot Vacuums: Suction power typically ranges from 2,500 to 6,000 Pa. Higher-end models may exceed this range.
  
• Cordless Stick Vacuums: These vacuums usually have suction power between 100 to 280 AW. Some models may offer higher suction for better performance.
  
• Upright and Canister Vacuums: Suction power typically falls between 100 to 220 AW. These vacuums are designed for deep cleaning tasks.
  
• Handheld Vacuums: These models generally have suction power ranging from 15 to 60 AW. They are suitable for quick clean-ups and spot cleaning.

Is 9000 Pa suction good for home use?

Yes, 9000 Pa is considered strong for most homes. It’s great for picking up dirt, crumbs, pet hair, and fine dust on both hard floors and low- to medium-pile carpets. If you have thick carpets or heavy messes, consider vacuums with 12,000 Pa or more.

What vacuum has the strongest suction in 2025?

Among robot vacuums, the Narwal Freo Z10 offers up to 15,000 Pa suction power, while the S20 Pro goes even higher at 20,000 Pa. For upright vacuums, models like the Shark Stratos™ reach over 23,000 Pa, making them ideal for deep carpet cleaning.

Which vacuum is best for pet hair and long hair?

Look for vacuums with strong suction and a tangle-free brush system. Models like the Narwal Freo Z Ultra and S30 Pro feature anti-wrap designs that cut through hair and prevent clogging, making them ideal for pet owners.

Is 150 AW enough for cleaning thick carpet?

150 AW can handle low-pile carpets and general dust, but for thick carpets or deep debris, 200 AW or more is better. A powered brush head also makes a big difference by lifting dirt out of the fibers.

What robot vacuum has the most powerful suction right now?

The Narwal S20 Pro and Freo Z10 rank among the strongest, offering 15,000–20,000 Pa suction. They combine this with intelligent features like DirtSense and auto-adjust suction to clean smarter, not just harder.

Choose the Best Vacuum With the Right Suction Power

Suction power is only one piece of the puzzle. The right vacuum should match your space, habits, and cleaning expectations. Whether you're cleaning hardwood floors or tackling heavy messes, choosing a model that balances strength, intelligence, and ease of use makes all the difference.

Narwal understands these needs deeply, not just building vacuums but creating tools that fit seamlessly into everyday life. If you're ready to clean smarter, not harder, this is where the upgrade begins.
