This variant comes with a foam cannon and the 10m hose (7m in other variants), you need at least 10m to do a car without having to constantly move the machine.
You had recommended this earlier. Think this would be fine for my usage? Also, this doesn't have wheels. Anything like this with wheels?

In fact Iíd suggest you get the same in a trolley type configuration as thatís much easier to move as itís quite heavy. Remember to adjust pressure down to 150 bar/2100 psi or lower as above this can damage and strip car paint. Also change oil at 150-160 hours instead of 200 hours as it gets quite dirty. Use full synthetic 10/15W-40 engine oil, in line water filter at the input also goes a long way in preserving pump life.
I dont find the trolley option on their website. Any other place I can find this with wheels?

Agree with the second half, but in my experience given how underpowered cheaper pressure washers are, sheíll struggle to clean anything effectively at 2.5-3ft. Pressure drops exponentially with every inch of increased distance from the target. Unless the surface is already flaking off, like old paint/cement, Iíd say about 8-9 inches will be perfect for floors but again, start further away and close in as needed.

Also donít forget eye protection, you can get safety glasses from Amazon. The last thing you want is fine debris getting into your eyes at high velocity.

This will work well-

https://www.starq.in/products/qpt-st...her-qt-1800hpw

Iíve used their machines before and theyíre good for the price, the best performance per dollar Iíd say. Support is also good, you can easily get spares in the future if need be.

Oil change is easy as pie, anyone can do it. Youíll need a small tray to collect old oil, a funnel to fill and synthetic engine oil (manual will mention the grade but for most units itís 15W-40), about 350-500ml depending on the pump size. Itís not like a car where you also have to deal with oil filters and gaskets.

Just flip the oil at roughly 85% of the operating hours the manual calls for (like with cars). For eg. on my machines itís every 100 hours, but I do it at 85-90 hours as the oil is quite contaminated by then. If you want to measure running hours precisely you can get a vibration activated hour meter. Given domestic use, even if you donít hit the running hours change it every 6 months as viscosity modifiers break down over time.

Itís a good machine, but Iíve linked to one with wheels above.

I may have exaggerated a little .

Also, pressure washing is part of your everyday life, whereas I have not had one for quite a few years. But I do remember being amazed at how aggressive even a small domestic model from Bosch was.

Brilliant point! I would never ever repeat the things I used to with grinding wheels in factories, polishing wheels as a hobby jeweller, etc, forty to fifty years ago, without it. But I hadn't thought of eye protection for pressure washing. Good education

Yes good point, perspective is everything and Iím probably used to more powerful machines so smaller ones seem even weaker when I do use them occasionally.

Itís like driving, that 180hp motor felt fast at one time, but once youíve driven cars with way more power, suddenly the same engine feels slow

Thanks again. What is the diameter of the input hose pipe for these machines? Any idea?

Diameter will be 0.5Ē for the garden hose that goes on the inlet side. Use a pre filter here to help stop debris getting into the pump.

Re: Buying & Using a Pressure Washer

When I go through this thread I see two foam cannons mentioned often, the MJJC and the JPT. The JPT is significantly cheaper. Is there a huge difference between the two?

Which one would you recommend?

JPT is one of the best cannons I’ve used, so will suggest that. Keep in mind with foam cannons, the price and quality rarely equate.

Best example will be the MTM PF22.2 which is hundreds of dollars and has the exact same performance as cheaper canons. You can see YouTube tests people have done over the years to verify.

JTP has two variants, I’m referring to this one- https://www.amazon.in/JPT-Complete-O...2C1079&sr=8-19

As for pipe and pre filter, any braided 0.5” garden hose from Amazon will do (ensure it’s braided as soft silicone pipes will collapse due to suction). For the pre filter connection I’ve set it up like this:

1) Zephyr female 0.75” thread that screws into the pressure washer inlet thread.

2) The other end of the Zephyr is a female quick connect that connects to the male quick connect attached to the pre filter threaded pipe (0.75”).

3) The other end of the pre filter threaded pipe also has a Zephyr quick connect that goes into the brass quick connect attached to the pipe.

In your case all these will 0.5”, everything else remains the same. You can get all of these on Amazon, just type Zephyr connectors in search. Keep in mind some pressure washers may have a female thread instead of male on the inlet, in which case you buy the matching adapter (Zephyr sells all types).

Using quick connectors everywhere ensures very easy pipe and filter removal when you have to clean/move the machine. Should look something like this-

Thanks again. Another question - we have a pressure pump installed for the entire house, so pressure in the pipes is about 80psi. Would that cause any damage to the pressure washer?

Happy to help.

Standard water pressure in most homes is around 20-60 psi. 80 is on the high side but wonít do any harm.

Your user manual will also mention the max inlet pressure, can vary slightly by machine.

When I was building the house I calculated that the tank is about 20 feet above my shower head, so that would give me only about 9psi with only the water head height. Hence decided on a pressure pump. In an apartment this is usually not an issue because tanks are so high that you usually get a good pressure at your outlets.
