The WW107S is a Suttner ST-601, a linear (in-line) trigger gun with a straight water path through the gun body. Use it to replace the trigger gun on your Whisper Wash surface cleaner. Whisper Wash's parts list shows it as the trigger gun on the models below.

Key Features

• Linear design: a horizontal, flow-through design with a straight water path through the gun body.

• Impact-resistant trigger guard.
