Troubleshooting The Whisper Wash Classic 19" Surface Cleaner

The Whisper Wash Classic 19" Surface Cleaner is the leading flat surface cleaner in the industrial pressure washing industry. This ergonomic, easy to use, flat surface cleaner is a popular choice for cleaning:

  • Patios
  • Pool Decks
  • Parking Lots
  • Other Large Flat Surfaces


If you're experiencing a wobbling or sudden vibration when you use your Whisper Wash, here are some common causes and how to fix them:

  1. Check the spray tip: If the spray tip is clogged, there will typically be an uneven spray pattern.
  2. To clear the spray tip, first remove the tip ( a 9/16 wrench is the perfect size for the job).
  3. We recommend keeping the C.A. Technologies Spray Gun Brush Cleaning Kit in your toolbox. While it's made for paint sprayer guns, the needles are a perfect size and shape for clearing the Whisper Wash spray tips.
  4. Once cleared and cleaned, reaffix the spray tip. Make sure to do this properly, taking care to align the line in the spray tip with the spray bar ( not sideways ). Watch the video to see how this is done.
  5. Ensuring the clearance is the same on both tips is important to keeping the Whisper Wash stable and smooth when in use. For example, if you have three threads showing on the untouched tip, you should insert the clean tip so that it has a clearance of three threads. It's important to balance the sides, otherwise there may be some wobbling.
