Can I use it to pressure wash my condo balcony with the nozzle it comes with?
1 answer-
NorthstarExpert7· 2 years ago
This would be a very low pressure spray at 100 PSI. The pump cannot be used softwash cleaners. I would recommend our NorthStar softwash sprayer for this application. Please view item #157140.
