Turbo Nozzle
A turbo nozzle, also called a rotary nozzle, is a pressure washer tip that spins a zero-degree jet in a tight cone. It cleans almost as hard as a pencil-point tip but covers a wider path, so it is used on tough flat surfaces like concrete, never on siding, windows, or roofs.

In depth
The spinning jet strikes the surface from a constantly changing angle, which lifts embedded dirt, oil film, and old algae from concrete faster than a fixed fan tip. The tradeoff is risk. Held too close or paused in one spot, it etches concrete, gouges wood, and drives water through any gap. Technicians keep it moving, overlap each pass, hold a safe distance, and test a hidden spot first.
How this shows up on our jobs
Madison driveways and garage aprons take salt and freeze-thaw punishment that leaves rough concrete holding dirt. On flat concrete we pair a surface cleaner for open areas with a turbo nozzle for edges, steps, and stubborn spots. Siding, roofs, windows, and wood never see one.

Surface Cleaner
A surface cleaner is a circular attachment — typically 16, 20, or 24 inches in diameter — that replaces the wand on a pressure washer for cleaning flat horizontal surfaces. Inside the housing, two or four high-pressure nozzles spin on a swivel bar, blasting the surface at a consistent angle and distance while a skirt contains the spray. The result: an even, streak-free clean across a driveway, patio, or sidewalk in a fraction of the time a wand would take — and without the wand-streak "zebra stripes" that plague amateurs.
Pressure Washer Nozzle Degrees
Pressure washer nozzle degrees describe how wide the spray fans out. Zero degrees is a pinpoint jet, 15 degrees is a narrow cutting fan, 25 degrees is the general cleaning fan, 40 degrees is a gentle wide rinse, and 65 degrees is the low-pressure soap tip. A smaller number means more force on a smaller spot.
PSI (Pounds per Square Inch)
PSI is the unit of pressure used to rate pressure washers, measuring the force of water exiting the pump per square inch of surface area. Consumer pressure washers run 1,500-2,500 PSI; professional rigs typically produce 3,500-5,000 PSI; and specialty surface cleaners can spike above 8,000 PSI. Higher PSI is not always better — in fact, for most home exterior surfaces, high PSI is destructive. Vinyl siding, wood shingles, soft mortar, roof granules, and painted surfaces all fail under excessive pressure.
GPM (Gallons per Minute)
GPM stands for Gallons Per Minute — the volume of water a pressure washer delivers per minute of operation. While PSI gets the headlines, GPM is what actually does the cleaning. Think of it this way: PSI is the hammer's strength; GPM is how many hammers you're swinging. Higher GPM means more water flowing across the surface, which means faster dirt removal, better rinsing of detergents, and shorter job times.
Unloader Valve
An unloader valve is the pressure-relief valve on a pressure washer pump that sends water back to the pump inlet when you release the trigger. It stops pressure from spiking against a closed spray gun, which would otherwise overheat the pump and burst hoses. It is why the machine relaxes between bursts of spraying.
