Introduction
If the Rug Doctor is not spraying properly, you may need to replace the pump .
The Mighty Pro and the X3 models have one pump , while the Wide Track (WT) model has two identical pumps running in parallel. This guide is written with the Wide Track model, but can be used for any of the three models.
Optional tools:
- Straight edge cutters/pincers instead of hose clamp pliers
- Clamp cutter/removal tool
- Hair dryer/heat gun
Ce dont vous avez besoin
-
-
For single-pump models (Mighty Pro, X3), if the Rug Doctor does not spray at all, the pump requires replacement.
-
For the Wide Track model, if the Rug Doctor does not spray at all, both pumps require replacement.
-
If water splashes out of the nozzles for the Wide Track model but does not spray adequately, check the spray nozzles for clogs first.
-
If the nozzles are clear, one of the two pumps may be defective, not supplying sufficient pressure to the nozzles. If possible, replace both pumps.
-
If you need to determine which of the two pumps requires replacement, switch the Rug Doctor on to the upholstery mode. Do not disconnect the quick-connect for accessories. If water splashes out of the nozzles like the carpet mode, replace the front pump.
-
If water does not splash out of the nozzles in accessory mode, replace the rear pump.

-
Use pliers to grip and wiggle the axle hub cap to loosen it.
-
Pull the axle cap off.
-
-
-
Pull the wheel off of the axle.
-
Pull the other wheel with the attached axle out of the body.
-
Slide the axle and wheels back onto the Rug Doctor.
-
Center a replacement axle hub cap over the exposed axle end.
-
Use a mallet to tap the hub cap in place. It should not feel loose on the axle.
-
-
-
-
Remove the crimped hose clamps securing from each end of the pump you are replacing.
-
You can use a clamp removal tool to cut the clamps.
-
Alternatively, use pliers to unlatch the small retaining tab on the clamp.
-
Pry the clamp apart to loosen it.
-
Use your fingers or pliers to pull the hoses off of the pump nozzles.
-
-
-
Cut the zip ties holding the bundle of wires together.
-
Carefully trace the two wires coming out of the pump you are replacing.
-
The pump wires should connect to a black wire and a white wire.
-
There may be a diode attached in-line on the red wire.
-
Disconnect the pump by pulling the wire terminals apart. This may take significant force. Pull at the terminals, not the wires.

I would like to view how to open the housing & replace the pump on the Rug Doctor model DC 1.
My X3 model rug doctor continuously sprays Until it runs out of water doesn't matter if the red button is pressed or not when you turn on the machine, it starts sprain. Any thoughts?
Hi Mike,
Does it full-on spray, or just leak? It could be that the red button is broken. Look through this guide. You may be able to disconnect the spray button wires through the black cutout. If the Rug Doctor still sprays with the button disconnected, then the problem is elsewhere.
We replaced our pump but still does spray. We have the doctor deep carpet cleaner model with single pump.
Do you know which way for sure the pump nozzles should be facing on our model? Maybe they’re in wrong though we are hundred percent sure it’s in how old one came out.
