Kranzle K1122TST Pressure Washer Obsessed Garage

Kranzle pressure washers have been the keystone of my business since I started Obsessed Garage. My very own K1122TST that I had for roughly 8-years ran like a tank. I parted ways with it once I set up my custom install. I didn’t have much use for it after moving to an on-wall solution. It had never been serviced. The only maintenance I did to it was changing the oil. It’s amazing how that thing operated so well for so long.

What’s so special about the K1122TST? Outside of its fit/finish and its uncompromising German quality, it performs exceptionally well.

I’ve done a serious deep dive on these Kranzle pressure washers. The numbers are really good. You’ve heard me say a million times how flow is far more important than pressure. This unit does about 2.0 GPM (gallons per minute) and the measured pressure came out to be roughly 1050 PSI (pounds per square inch).

These numbers indicate that we are getting the ideal amount of flow and pressure to wash our cars. Not only does this thing perform well, but it also looks freaking amazing. If you’ve been following me for any amount of time, you know that I want products that work and look good. Having the combination of aesthetics and functionality is OG spec.

The convenience of having a pressure washer you can wheel around gives you complete control over where you want to set up to wash your car. Not everyone wants to wall mount their pressure washer, so this is a great alternative.

The K1122TST measures at 40” length by 13” width by 17” height and weighs around 80 pounds. So, storing it away will be super easy to do and it won’t consume a ton of real estate as a wall mount solution would.

If you want to have the full experience like me, you’ll want to get the Complete Kranzle Pressure Washing Solution. With the K1122TST by itself, you’re going to get all of their OE accessories. Although not bad, we want better than OE. In my solution kit, you’ll get MTM stainless steel garden hose QDs, Mosmatic (swiss-made) QDs, an OG Spec Wand, an OG Spec Mosmatic Sprayer, and a Griots foam cannon with a Mosmatic stainless 1/4” plug. 

This will be everything you’ll need for the perfect portable solution.
