“Does this stay on and make a humming sound even when you are not spraying? If so, how loud is it?”

• The machine is overall very much quieter than a gas one, it’s quiet when not spraying.

• Yes it does but it’s not too loud. Sounds like a hand held sander.

• Hi rberumen. The Greenworks 3000 PSI has the continuous run pumps, which features a continuous-run motor and pump that operates like gas-powered pressure washers. It has a pressure switch built in to regulate this process. It makes it so much quieter in between uses and rest times. This unit is not a Total Stop System. We hope this information helped!
