Last time our teen-aged nephew visited, he helped to clean our paver block driveway with a gas powered pressure washer - with only the normal pistol gripped, extended spray head wand. Holding the wand, and continually swinging it back and forth ,, well that proved to be tiring. Our arms were sore from resisting the pressure, and the spray head nozzle often wandered...to scatter dirt and debris.This year we bought the pictured attachment from Home Depot. so I could do the job alone. It snaps onto standard wands, replacing the nozzle ...and sweeps easily (like a vacuum cleaner). The rotating nozzles stays close to the surface and overspray is contained by the housing.
Trust me...the job was far quicker and easier with this amazing surface cleaner attachment. It cost less than feeding a teen-ager. Yes! What a great idea!
