First, the important points.

1.Look for vacuum cleaners with brushless motors that spin faster than 100,000 rpm rechargeable handheld vacuum cleanerand multi-cone cyclone separation technology.

2.Most vacuum cleaners in hard ground performance difference is not significant; the difference is primarily in carpet vacuum and mite removal ability, so a good vacuum cleaner can not only floor carpet through, but also replace the mite removal instrument.

3.Dyson vacuum cleaner is still the most comprehensive product strength, not bad money directly on the latest model, but you must know it over performance.

4.For cost-effectiveness, you can choose old Dyson products; for cost-effectiveness, some domestic thousand-dollar products are also very good.

Suction power vacuum cleaner could be a play on words.

Even if you are unfamiliar with vacuum cleaners, you are aware that suction power is the most important indicator that largely determines a vacuum cleaner's performance. In general, manufacturers indicate how much suction power they have in two ways: Pa and AW.

Pa stands for pressure and is the static pressure value generated by the vacuum cleaner brush head Zimmermann Kids HKin a relatively sealed situation. It can represent the suction power of a vacuum cleaner to some extent. When vacuuming soft materials such as carpets, quilts, pillows, and so on, the vacuum cleaner brush head is held tightly against these materials, forming a relative vacuum, and the suction power can be measured in Pa.

However, these are not the only places where we use vacuum cleaners; we also have to deal with hard ground such as tiles and floors, so there is a gap between the brush head and the ground, and suction power cannot be measured by how much Pa, so AW (suction power generated by pneumatic power) is introduced.

AW (suction power) = dynamic pressure (air flow) x static pressure (vacuum suction), which includes both the air flow generated when the vacuum cleaner moves on hard ground and the static pressure value generated when the vacuum cleaner moves on soft ground, more accurately reflecting the vacuum cleaner's total suction power size.

As for why some manufacturers prefer to use Pa as an indicator, I believe it is because the vacuum suction number is larger and more visually appealing, and Pa is more easily understood because most people understand that it represents pressure.

Brushless motors are the key to increasing vacuum cleaner suction power.

Most low-end handheld vacuum cleaners costing a few hundred dollars use Jimmy Wongbrush motors, have speeds of around 30,000 rpm, and suction powers of no more than 30 watts. To get more suction power, you must first significantly increase the speed of the motor. Because traditional brush motors have carbon brushes, increasing the speed will not only cause the motor temperature to rise, but will also cause wear and tear, reducing the service life. Brushless motors do not have these issues.
