A bare hose, or a cheap plastic nozzle, lets the water fan out the second it leaves the end. Spread-out water has no punch. It is the same reason your thumb over the end of the hose suddenly shoots water across the yard. You are not adding pressure, you are focusing the flow you already have. Most nozzles are built to be gentle, so they do the opposite.

This was the advice everyone gave me. So I went to buy one. Three hundred dollars for a decent model. Then the salesman starts listing what comes with it.

You store the giant thing in the garage you already cannot park in. You keep gas around, or you pop a breaker running it off an extension cord. It is loud enough to annoy the whole street. And if you hold the wand wrong, you strip the paint right off your own car.

Detailers will tell you a proper wheel clean takes twenty five to forty minutes per corner by hand. Multiply that by four wheels, then add the car, the driveway, and the patio furniture. Before you know it your Saturday is gone and your back is done. There is a reason "I will get to it next weekend" turns into three months of grime.

A big-box pressure washer can push four gallons a minute. Run it for an afternoon on the driveway, the siding and the cars, and you are into the thousands of gallons. One homeowner online admitted he "cringed when the water bill came in." A focused nozzle uses a fraction of that, because the force comes from shape, not volume.

What I use now is a small metal nozzle that screws onto the end of the same hose I already had. Instead of letting the water spread out and dribble, it narrows the channel and sends the flow out with real force. Same hose, same tap, about three times the pressure. No electricity. No gas. Nothing to store.

The first time I aimed the tight jet at the old oil stain on my driveway, I stood there longer than I needed to, just following the clean line behind the water. My wife came out to see what I was laughing at.
