Suction when vacuuming - Vacuums

What is the question about the suction you want answered. The suction needs to be lessened when going over rugs. Basically though, the suction is the movement of air and if there is no movement or the air cant get through, you Will not get any suction. Try putting a quarter on the floor and setting the hose flat on the floor around the quarter and turn it on, the quarter will stay in place as long as you don't move or lift the hose. There has to be a means for the air to move in order for it to work.

Some vacuums have a valve or collar near the handle that you can twist to adjust the amount of suction on the vacuum. If you open it a little it will stop sucking up your throw rugs. IF the problem is not enough vacuum then the HEPA filter may be clogged. It's usually a rectangular filter in a plastic frame. That has to be changed occasionally or the suction of the vacuum will continue to drop off.
