The suction and air flow are measured with the air flow being restricted by a two inch opening. The formula for Air Watts is as follows: (Air Flow * Vacuum)/8.5 = Air Watts. The Air flow is in Cubic Feet per Minute (CFM) and the Vacuum is in Inches of Water Lift.

Beside this, how do you find the suction power of a vacuum?

The sealed suction of a vacuum cleaner is measured in inches of water lift. This rating is taken when the motor is totally sealed, and the term refers to how many inches the motor will vertically lift a 1" column of water.

Also Know, how many air Watts is a good vacuum cleaner? An upright vacuum cleaner should be around 100 air watts and a cylinder vacuum cleaner needs to be about 220 air watts.

Secondly, how can you tell how powerful a vacuum cleaner is?

Use air watts This measuring method is usually about a number of watts a machine uses to carry a unit of air through a vacuum cleaner nozzle. It is the best measurement that shows the strength of suction. It works well with users who know cubic feet per minute and water lift of a vacuum cleaner.

What is kPa suction power?

Suction Pressure (Water Lift or Sealed Suction) Typical domestic vacuum cleaners can create a suction of 20 kPa. Pascal is a measure of pressure that equals to a pressure of 1 newton of force per square meter of area. 20 kPa would be 20000 N/m2 or around 2 tons per square meter, or around 200 cm (80 inches) of water.

Does higher wattage mean more suction?

Naturally, the suction power is generated by the vac's motor, and if one compares models by comparing watts to watts, generally it can be said that the larger the motor (the higher the wattage), the better the suction power. Most often this is true, but it is not the whole truth.

What is PA in vacuum?

The SI unit of pressure is the pascal (symbol Pa), but vacuum is often measured in torrs, named for Torricelli, an early Italian physicist (1608–1647). A torr is equal to the displacement of a millimeter of mercury (mmHg) in a manometer with 1 torr equaling 133.3223684 pascals above absolute zero pressure.

Why do vacuums lose suction?

A motor generates power which powers a vacuum which, in turn, creates suction to lift debris. The most common areas of suction loss are within the hose itself, the vacuum bag, clogged rollers, broken vacuum belt, or a faulty gasket. All of these problems will lead directly to the vacuum cleaner losing suction.

Does wattage matter in vacuum cleaners?

The simple fact of the matter is that wattage is only a measurement of how much power (or electricity) will be consumed. If you want to use more electricity, then use a vacuum cleaner with higher wattage.

What does kPa stand for in vacuum?

It's typically measured in kPa (kilopascal). Without going into details, Pascal is the measurement of pressure and the kPa unit of a vacuum cleaner is the difference between the normal atmospheric pressure and the pressure inside the vacuum cleaner hose.

What makes a good vacuum?


It's no surprise that a quality vacuum cleaner should have a front and center spot in your cleaning closet. Canister vacuums offer better mobility and are also great for stairs, but often have smaller dust bags. Handheld and stick or cordless vacuums make handy tools for quick touch-ups.

How is vacuum measured?

The common metric unit for vacuum measurement is the millibar, or mbar. Other pressure units sometimes used to express vacuum include the interrelated units of atmospheres, torr, and microns. One standard atmosphere equals 14.7 psi (29.92 in. Atmospheric pressure is measured with a barometer.

What is aW in power?

A attowatt (aW) is a decimal fraction of the derived unit of power in the International System of Units (SI) watt, which is defined as one joule per second. Power measures the rate of energy conversion or the rate at which work is done.

How many amps should a vacuum have?

Most upright cleaners are seven to 12 amps. Many canister models are 12 amps. The maximum allowable amps that can be plugged into a household outlet is 12 amps. So even if your vacuum has the highest possible amps, it does not mean that is is necessarily the better the vacuum.

Is Miele better than Dyson?

The main difference between Miele and Dyson vacuums is that Miele's vacuums use a bag for the dust collection whereas Dyson vacuums are bagless and now even filterless. The technology used by Miele vs Dyson in their vacuums is therefore quite different. Most Mieles are quieter than Dysons.

What does kPa mean?


Kilopascal (Kpa)is a pressure measurement unit. As the name implies there are 1,000 pascals in 1 kilopascal. You are most likey in north america or your using an american product mayber a car tire and you need to know what pressure to fill it to. If your looking to convert psi to kPa go here.
