Vacuums must have great suction in order to properly remove debris and dirt from floors. The factors that influence vacuum suction vary greatly; doing some homework before purchasing a machine will help, and knowing proper use and maintenance will keep suction strong.

Suction power is directly related to air wattage. Different types of machines require specific wattages to function efficiently. Uprights require fewer air watts than canisters.

A powerful motor, combined with airflow efficiency, creates ideal suction. To ensure optimal airflow, avoid vacuuming pieces of metal, string, or other items that could clog the machine, check filters, empty bags regularly and inspect the machine’s tubes and beater bars after each use.
