We have a built in Electrolux 1590 that seems to have very little suction. I cleaned the filter, but in trying to put it back together, I need a picture of how it's supposed to fit. (We bought the house last April, and don't have a manual for the vacuum.)

Once the filter is in place put the retainer on and turn it 1/4 turn clockwise.
A manual can be found at the following site under new models, Centralux.
