How do you use vax 2000 to shampoo carpets. do not have a manual

Set up is complicated unless you are patient.
Remove the paper dust bag from the bottom of the canister and then filter ring. Then put in the recovery bucket of which 4 litres of warm water should be added and a capful of floor cleaning solution.
Then remove the pump wire on top of the Vax motor where the blue filter circle is (keep the filter in, do not remove it!).
If the 2000 has a separate pump notch on the rim of the Vax motor head on the outside then you should plug the black cord in that has a washer screw type metal connector. Push, twist and lock in. Then the black cord which eventually leads to a clear pipe with the older clip on wash handle that has to be clipped to the main hose handle has to have the black and see through cord clipped to the main hose and eventually down the extension pipes until you get to the floor head. If you have the older style T shaped floor head the cord should slip into the floor head easily. Then either squeezing the trigger to release the cleaning solution in, switch the Vax on and hit the secondary pump button. This will pump the cleaning solution and water into the carpet. To stop the pump you can either lock the wash trigger to stop the liquid or squeeze the trigger to make sure no other liquid comes out. Generally you can see the foamy carpet solution flowing through the see through rubber hose and eventuallly through the floor head.
To **** up the rest of the carpet solution, stop the pump button and the Vax can be used to **** out all the dirty solution/water in the carpet. Its a big and tedious task generally!
See an alternative manual for the Vax 1000 which is an older model but similar to the 2000. It is free and in pdf downloadable form:
