The =93window nozzle with hook=94 part no. BI-2149871 gets plugged-up frequently. The problem is not that it gets plugged-up. It is normal for things to get plugged whenever cleaning anything. The fact that you have to remove and then re-install two Phillips head screws every time it does in order to remove and clean under it just plain stupid. Bissell could easily have put in a couple of latches or hooks for this but either some idiot overpaid engineer or executive decided to put screws instead. Get with it Bissell.
