About Vacuum Cleaners

vacuum cleanersThe essential tool within the carpet cleaning industry is the vacuum cleaner. Vacuum cleaners are available in all sorts of shapes and sizes. However, they were mainly designed for various cleaning applications. This can be categorised into two primary groups—those made to remove dry soils and others intended to extract liquids. In addition, several attachments are available for use with most of these vacuum cleaners.

First and foremost, let us define the meaning of “vacuum”. A vacuum is an area that has been intentionally depleted of air, while a vacuum cleaner is a device designed to generate and confine such a space. As well as utilising a partial vacuum for cleaning as in a vacuum cleaning system.

How Vacuum Cleaners Work

Vacuum cleaners contain a vacuum motor. Because a vacuum is unnatural, the air fills the void. It is the removal of soil from a surface through suction. Generally, vacuum cleaning is a form of sweeping to remove dry soils.

A vacuum does more than clean your floors and carpets, which is why I appreciate your vacuum. It helps you collect pet hair from rugs effectively. When assessing a vacuum cleaner’s performance, consider its airflow and suction ratings.


Airflow relates to air volume and is entirely different from the suction. Therefore, a high-efficiency vacuum must be able to move 156 (CFM). In contrast, a high-efficiency vacuum cleaner, mainly designed to remove liquids, might only have the ability to carry 88 (CFM).

Inches of water lift is how high a vacuum motor can lift a column of water one inch in diameter within a tube. At that point, no airflow is there, only suction. Special handheld vacuum gauges for measuring ‘inches of water lift’ are available to measure vacuum cleaners’ suction. For instance, a high-efficiency vacuum cleaner for dry soil removal on the carpet might have an ‘inches of water lift’ rating of only 12″. In contrast, a high-efficiency vacuum cleaner mainly designed for removing liquids might have a rating of 150″.

Hence, the balance between a vacuum cleaner’s CFM rating and the “inches of water lift” rating determines its most appropriate cleaning application.
