Q: Does this have a tank for soap ?

8 months ago
1 Answer
  • A: Thanks for the question, Reba. No, this machine does not have an on-board soap tank, but it does have a siphon tube that will allow you to apply detergent. You will easily be able to apply detergent by attaching the siphon tube to the barb on the pump and placing the filter end of the siphon hose directly into a pressure washer safe detergent. We hope this helps!
