The Restriction Affliction

If you start hearing the vacuum motor sounding like an F-18 jet, there might be a restriction in the vacuum system. This sound is usually accompanied by poor cleaning of the lane.

Check the filter in the recovery tank. This filter is sometimes overlooked and needs to be cleaned and or replaced when it becomes obstructed.

Every place that the air changes direction is a place for a potential restriction. Check the elbows by removing the clamps and hoses. Often a large “Lint Monster” can be found in these places.

On battery operated machines, restricted airflow can cause the vacuum motor to draw more power and shorten the battery life.
