The “window nozzle with hook” 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.
