First, check that you have full vacuum to the machine from the wall. The 
house vacuum lines corrode, due to the bleach vapors from your waste tank.

I've also found that the plastic vacuum lines in the machine can become 
clogged over time. You can try opening the control panel and use clamps to 
close the line from the stream waste collector to get more vacuum to the 
nozzle. I had to flush (several times!) the whole pathway from the waste 
collector to the tank with detergent. I forced detergent BOTH ways to flush 
the tubing, and I saw that it was indeed quite full of junk. The little 
fittings can become clogged easily.
