Rm200 can last u 20 months of wash at rm10 cash wash per month.
Cheaper, easier...
And that cheap pressure wash might not last that long though

Is your car super dirty? With mud? If not, why do you need jet spray?

The purpose of the pressure washer is to remove those dirt effectively before starting your wash.

If your car is not very dirty, just use normal pressure from the tap to loosen those dirt.

I have a pressure washer but rarely use it coz it’ll take more time for me to wash the car with it. Why? Well, you’ll need to know that you’ll have to take it out and set it. That’ll take perhaps 5-10 mins? After that, another 5 - 10 mins to store it away. Unless my car is really filthy (which is very very rare), then only I’ll use the pressure washer.

Other times, normal wash would do. So far, No problem with my cars’ paint etc.

I got a Karcher, used it a couple of times and sold it... didn't like it because no wheels, you have to carry it everytime you move to a different spot.
Got another pressure washer, an Italian brand (can't remember name) last year... until today still sitting in the box, never opened.

I found using the garden hose good enough... using pressure washer, need to manage electric cable, garden hose, and pressure washer hose.
Slowing down rather than speeding up the car washing job.

If the pressure washer can peel off your paint.. then your paint not good enough in the first place.
For it to be possible, you probably need 3 things to happen... 1) Bad paint job, 2) hold the lance super close, 3) hold it in that position for a long time.

My advise... if your garden hose pressure good enough, don't bother getting a pressure washer.
Long ago i also thought it was a good idea... but in 7 years of owning pressure washer, i use it like 5 times at most.

If you think pressure washer can save time, withdraw that idea.

I have a black decker jet washer at home and other than jet cleaning the car porch, I find the idea of using it for car wash really redundant. It saved non of my time.

You first have to assemble it, and after using you have to dismantle the parts and dry the water left in the pipes and keep the cables & pipes (really long pipes). And the water pressure is too strong to be useful for car wash, I prefer the water pressure from my normal hose.

It served me for the first one or two car wash and after that it was left at the corner to rot. Mind you it's not cheap too and if you divide the price to how many times you would actually use it, I think it's best to drop the idea of buying one.

Probably useful for cleaning your yards & porch but not your car.

Not really, I use water jet to wash components below the car and inner surface (dk how to explain) surrounding four tyres. You never know tyres pick up rocks/muds and stick to inner surface surrounding. Normal water pressure cannot remove it, still can feel like rough layers. So, water jet come in handy.
