Some things are popular because when the machine is finished desperate work rounds are required for all the things that were never thought of, put of for another day or simply forgotten in the excitement of near completion.
This may or may not be one of those things.
I always want a good flow of suds. I like a variable speed pump so I can adjust the flow. You can filter most of the guck out but some will get through making flow control with a tap tricky.
Suds requires side curtains to catch the spray and two nozzles are better than one because clamps, fittings and stuff can so easily get in the way. I return suds to the tank using Koi carp filtration bags. A good long nozzle on the air duster keeps the pipework clear.
