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).
The current owner's manual, MAN-47328 Rev. B (March 2019), covers models 700-041-030, -031, -032, -035, -036, -330, -331, -332, -333, -334 and -407. Earlier machines are covered by their own editions, going back to c. 1987.
Before ordering, check the model number on your machine's data plate. If you are unsure, contact us with the number and we will confirm the correct part.
Confirmed against the HydraMaster parts lists in the 2011 owner’s manual (models 700-041-006 and -007), the 2014 edition (700-041-006, -007, -014, -316, -318 and -322) and the current 2019 NEXTGEN edition, MAN-47328 Rev. B.
In the NEXTGEN parts lists it is item 1 of vacuum shoe and skid assembly 000-064-012. Vacuum head assembly 604-053-100 carries five of those shoe assemblies, so a complete re-gasket takes five gaskets, not one. The same vacuum head is fitted to every NEXTGEN variant, including the CE 230 V 50 Hz machine, model 700-041-036, which is the one we supply.
