poor cleaning performance...
To Gary in Canada
Your DAM cleaning problem is an easy fix. Tip the machine forward and lay it on the floor, then locate the handle counterweight spring. It will be located on the right middle of the underside, and be stretched from just above the right front wheel to the rear edge of the housing, connected to a little hole under the bumper guard.
Unhook the spring from the housing, and reattach it to the rear wheel shaft, next to the right rear wheel.
This should correct your poor performance, and allow the nozzle to come in contact with the rug.
Hope this helps!
