guessing the whirlaway not effective on block driveways ?
a good question for those interested in adding jetwashing.
No - not when there is alot of moss/grass growing between the blocks. a turbo nozzle also called a dirt blaster is what you see here. although slower than the whirlaway cuts through anything and uses less water in the process. This is my tool of choice for block paving.
When cleaning other surfaces, patios ect the whirlaway is much faster, then use the turbo for detailing edges, corners, steps, walls and so on.
final stage is a rinse with the high/low pressure lance.
