Which RX-20 does this fit?
HydraMaster has built the RX-20 since the 1980s and there have been many revisions. Carpet Cleaners Warehouse supplies the current machine, the RX20 NEXTGEN, model 700-041-036 (CE, 230 V, 50 Hz).

Frequently asked questions
How many do I need?
One per machine, in the handle trigger assembly.
Solution will not shut off cleanly. Is this the fault?
Often. A worn micro switch shows up as solution that keeps running, or a trigger that only works held at an angle.
Is it the same as the momentary switch?
No. The momentary switch is a separate part in the same assembly.
