Water Lift (H2O)

Water lift (H2O) mainly measures the central vacuum’s engine strength, that is to say the strength with which the air is moved. The speed at which the air moves is a good indicator of the suction power. This data indicates, among other things, if the chosen power unit will be able to suck up larger debris of a certain weight. It is therefore an important element to consider when choosing a vacuum cleaner, especially if you intend to use an air driven powerhead: the greater the suction strength, the faster the roller will turn! This data is also crucial if you want to use the retractable hose system because it is precisely this force that will make the hose retract into the piping system.

Airflow (CFM/CMH)

This data measures the quantity of air that is moved at the same time, in cubic feet per minute (CFM) or in cubic meter per hour (CMH). A high airflow creates an important air movement, thus considerably increasing the capacity to vacuum dust and dirt within a larger range. This data is more important if you intend to use an electric powerhead: since it’s the electricity that will make the roller turn, the air movement created is of greater interest.

Having understood the respective functions of these two technical terms, it is important to know that these two characteristics ensure a maximal power altogether. It is therefore essential to analyse both of these data as a whole, and not independently.

Airwatts

Airwatt is a measurement that represents the motor performance, taking both these technical data into account. It is in fact calculated with a ratio between the airflow (CFM/CMH) and the water lift (H2O). It is therefore a major technical data that must be considered, although it is very sensitive to other factors, and so it would be inconvenient to only consider the Airwatt.
