Dirt Killer (DK) nozzles, which feature a rotating turbine, deliver the punch of a 0° nozzle with a 25° fan. This creates 10 times the cleaning impact of standard flat tip nozzle - effectively cutting cleaning time in half. DK spins faster. Good for cleaning wood, brick, paint prep., etc. Dirt Killer nozzles can easily be rebuilt.
Make sure you select the correct nozzle size.
