Why Buy an Cold Water Pressure Washer?
Pressure washers are a modern invention using an ancient idea: restrict water flow and heighten water pressure. Your garden hose, if left on for a minute, will lose about 8 gallons of water. A garden hose with a household spray nozzle will lose about 5 gallons per minute, but as a result, will put out much more pressure. A spray nozzle still wont clean anything, though, because you need a sprayer with a higher pressure in order to actually remove stuff; a sprayer will just push the gunk around.
