water cooled motor Karcher? seems like only starting from K4 model.
Mya I know the advantages of getting a water-cooled motor? can run it longer without spoiling motor?
water cool or not, In my opinion (you can choose to ignore) we don't use pressure washer that long to rinse our car. Universal motor is definitely enough.
10 mins max? With pressure washer it is definitely faster and consumes less water compared to a garden hose.
To maximise lifespan of any pressure washer:
Always prime your pressure washer. Never directly turn on tap and switch on motor. You want to get rid of air bubbles in the compressor first.
1. Turn on water tab
2. Without the pressure washer switched on, release the trigger and have water from the hose flow to your nozzle/lance. The natural pressure of the water from garden hose is sufficient to do that.
3. Make sure water flows out smoothly and no longer have air exiting.
4. switch on pressure washer motor.
Air is compressible while water is not. Having air in the compressor/piston is a big no-no as it will upset the mechanism.
For longer lasting motor, there is induction motor (heavier and longer lasting) vs universal motor (carbon brush + lighter)
depending on how long you want to run the machine, if longer than 15 mins, get an induction motor.
Personally I bought an induction motor pressure washer from europahilt. You may check it out, it's an alternative from karcher which imo is a bit pricey. Europahilt uses lavor motor, which is a renown italian brand pressure washer.
