Took A Licking And Still Kickin'
I bought a K3.92 in January 2006; never read the instruction on Type of Detergent and filled both tanks with Dishwasher Thick Liquid that I had quit using when it clogged up the Dishwasher. This did not flow well and within two years had clogged the Karcher up completely. I got New Detergent and a Spare Parts Kit, and soon had it working like new again.

Just love it for the boat and automobile washing. I only use diluted car or boat wash liquid now and especially for the Huge Concrete... more

Power Washer And Flat Surface Cleaner
We purchased the power washer from Pressure Washers Direct cheaper and with higher psi than any power washer we could find in the local big box stores.

It was shipped for free and arrived quickly. It was easy to assemble with only 4 screws and one Phillips head screwdriver. The only problem we found was that the on/off switch had been loosened or was never mounted correctly. My husband took care of that very quickly with a slight nudge of pressure to pop it into place.

My 3.70 Lasted Half A Year
I got a bad quality Karcher- the plastic pressure housing cracks after a couple times of use and it starts to leak and cannot build up the right pressure.

It should work a little bit longer. I have ordered a new housing today, let's see how long that one holds together.

PWD RESPONDS: Karcher has a 1 year replacement warranty to the original purchaser; it's called the Rapid Replacement Program.

Give Karcher a call at (800) 537-4129 to take advantage of the program.

Never A Karcher Again
I thought I was buying well known brand. This washer only lasted one summer.

I used for normal things- deck, cars, etc. The main brass fittings where hoses connect started leaking. I tried several times replacing the little o-ring washers (which alone is not a good design).

You can't work on the lower unit without taking the entire thing apart. The first thing I didn't like after 10 minutes of use is the unit is top heavy, it was always falling over.

So..This was my first and last... more
