Based on the suction power of the best cordless vacuum cleaner, what should it be like?

Strong suction should rival corded models.

The best cordless vacuum cleaners are expected to offer suction power that comes close to, or even matches, traditional corded vacuums. Ideally, they should generate at least 100 air watts (AW) or more in standard mode, and over 150 AW in max power mode. This ensures they can handle everything from fine dust on hardwood floors to embedded debris in carpets.

Multi-surface performance matters.

Good suction isn’t just about raw power—it’s about adaptability. A top-tier cordless vacuum should automatically adjust suction depending on the surface. For instance, it should reduce power on hard floors to conserve battery and increase it on carpets or rugs to dig deeper into fibers.

Efficient airflow design boosts suction.

Beyond motor strength, airflow design plays a big role in suction efficiency. A vacuum with optimized air channels and sealed systems prevents loss of suction, especially as the dustbin fills. This ensures consistent performance from start to finish.

Real-world pickup power is key.

Lab ratings aren’t enough. The best suction power translates into visible results—like picking up cereal, pet hair, and fine dust in one pass. Look for vacuums that pass real-world tests, not just technical specs.

Suction shouldn’t drain battery too quickly.

Powerful suction must be balanced with smart energy use. The best cordless vacuums offer high suction for tough messes but also include eco or auto modes to extend runtime without sacrificing performance. Ideally, a model should run at least 30–60 minutes per charge, even when used efficiently on mixed surfaces.

FAQs

What is good suction power for a cordless vacuum?

A good suction power for a cordless vacuum typically ranges from 100 to 200 air watts (AW). For regular household cleaning—like dust, crumbs, and pet hair—100 AW is often enough. However, if you're dealing with carpets, larger debris, or ground-in dirt, you'll want something closer to 150 AW or more.

Keep in mind, air watts measure the actual effectiveness of suction—not just the motor’s strength. Some brands also list suction in pascals (Pa), especially with stick vacuums. In that case, anything over 15,000 Pa is generally considered strong. The best cordless models combine this suction with a sealed airflow system and efficient brush heads to maximize cleaning results across different surfaces.

Where can I find an honest review on Dyson vacuum cleaners?

If you're considering a Dyson but not sure which model fits your needs, it’s worth reading a detailed review on Dyson vacuum cleaners. Dyson has a wide range of vacuums—from lightweight stick models like the Dyson V12 to more powerful options like the Gen5detect. Each has its strengths, depending on whether you're cleaning pet hair, thick carpets, or just need something compact for daily dust.

A reliable review on Dyson vacuum cleaners should cover suction performance, battery runtime, ease of maintenance, and value for the price. We've put together a comprehensive review that breaks down each model by use case to help you choose the right one for your home.

Which cordless vacuum has the strongest suction?

As of now, several cordless vacuums are known for delivering top-tier suction power. Among the strongest:

  • Dyson Gen5detect – Delivers up to 262 AW, making it one of the most powerful cordless vacuums available. It excels on carpets and hard floors alike.

  • Tineco Pure ONE S15 Pro – Offers around 150 AW with smart suction adjustment based on dirt levels.

  • Shark Stratos Cordless – Provides powerful suction and anti-hair-wrap tech, often praised for its performance on pet hair and rugs.

While Dyson leads in raw suction power, other brands like Tineco and Shark provide strong performance at a more competitive price. Remember, the strongest suction isn’t always the best choice—it should also be efficient, easy to control, and paired with good battery life.

Is 20,000 Pa suction good?

Yes, 20,000 Pa (pascals) of suction is generally considered very good for a cordless vacuum, especially in the mid-range to high-end category. To give context, basic models often start at 8,000–12,000 Pa, while advanced ones range from 17,000 to 30,000 Pa or more.

With 20,000 Pa, a vacuum can easily handle fine dust, pet hair, food crumbs, and even heavier debris on both hard floors and low-pile carpets. However, the actual cleaning performance also depends on the vacuum’s design, brush head, filtration system, and how well the suction is maintained throughout the session. So while 20,000 Pa is a solid benchmark, it works best when paired with efficient engineering.

What should I look for in the best cordless upright vacuum cleaner?

When searching for the best cordless upright vacuum cleaner, there are a few key features to keep in mind: suction power, battery life, ease of maneuverability, and dustbin capacity.
