This is a common manual tool for use on both bare floors and low pile carpet, mats or rugs.
Push the lever one way to make the brushes retract for rugs.
Push it the other way for brush use on bare floors.
Common fit 1 1/4 in. For most central vac wands.
*** Other options for rugs carpets are:
1. NON-electric Air Driven tool. This is similar to an electric roller..however the air suction makes the roller spin. If you have reasonable suction, it works great.
2. Electric powerhead like the Airstream Power Roller. Obviously the most powerful. You must have an Electric hose for use - a hose with a power cord on the wall end.
