The History of Pressure Washing Machines

Today’s writing comes from Andrew Thompson, founder of ViperTech Mobile Pressure Wash. He gives his unique insight into the history of power washing and adds his humor. I’m sure you’ll enjoy today’s tidbit from him.


If you think about, we have so many inventions nowadays, and one thing that I commonly see being used in homes and commercial properties and power washers. With that, an interesting question popped into my head while eating a delicious chicken fajita taco from Whataburger. How were pressure washers invented?

I’ve been power washing in Houston for several years now, and after being accredited by the BBB, receiving many golden reviews, and serving many satisfied clients I decided to do a little digging.

It turns out that two people say they invented power washing, and well it’s only up to us to speculate who did it?

On one hand of the coin, we have the Germans with their brilliant technology and rate of advancement where the power washer came from Alfred Karcher, the owner of the major Karcher brand. It doesn’t surprise me, though, that they would make such claims. After all, they are one of the largest manufacturers of cleaning devices, and an invention coming from them seems plausible.

Now, on the other side of the coin we have a man by the name of Frank Ofeldt. I’ve read an interesting article that states that the reason the power came from Frank Ofeldt was because of the prohibition movement back in the 1920s.

What happened was that Ofeldt was tinkering around with a few schematics trying to make a device that would eventually create illegal alcohol. He was having success with it, but by accident, he discovered something interesting. An accident like this sounds way too much like the movies, but sometimes our best inventions come from accidents!

He was messing around with a machine that produced steam, and as he turned the device upside down he found that the steam would push out, and the grease on the floor would move!

Ta da! As if by a stroke of magic he discovered that he could remove oil. Instead of pursuing the path of illegal alcohol production, he thought it wiser to invent a the machine that could remove stains from the ground.

So who discovered the power washer?

I can’t tell! It’s somewhat bothersome if I want to geek out on it. It reminded me of my childhood when I said a word and then everyone started using it but was I the first to say it?

Well, the great news is that regardless of who invented this machine it’s because of them I’m able to serve all of Houston, Pearland, Humble, and Sugar Land. If you’d like to see some of my work feel free to visit me at:
