Use of a cleaning head can increase the efficiency of your protein skimmer by up to 20%.
On all skimmers, if you watch them over a number of days you will see the amount of waste collected fall off with time. This is because as the foam rises it deposits some of the fat and proteins that it has collected on the side of the riser tube. This deposit makes it harder for the foam to climb and so the amount of waste in the cup decreases.
Most skimmers will collect a good inch of thick dark waste over a period of 2-3 days. If you do not clean the cup at that point it may take another week to collect the same volume.
The idea behind the cleaning head is that every 1-2 hours, brushes on the head clean the inside of the riser tube and keep it spotlessly clean. No additional water is used for this as the wetness of the foam is sufficient if done on such a frequent time scale.
Once a day, depending on the rate that the waste is collected, it is possible to energise a solenoid to flush the collection part of the cup with fresh water via the pipework attached to the head. A special auto syphon pipe allows the cup to fill up and when it reaches the top of the crook of the pipe runs away to drain until the cup is empty and the syphon breaks.
Will add an additional 115mm to the height of the skimmer.
