Q: Does it have a soap tank

7 months ago
1 Answer
  • A: Thank you for the question, Darrel. 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!

Q: Why does this engine not have a throtle control lever

a year ago
1 Answer
  • A: Great question, Dana. The engine manufacturers actually have determined that pressure washers are designed to run at full throttle, so a throttle lever is not necessary. Hope this helps!

Awesome washer, only thing that gave it 4 starts was the not so good description of how much oil to use in the gsx210 motor. Runs good and sprays awesome.

Powerful Mobile Washer

I purchased this about one month ago to pressure-wash my deck and pontoon. Powerful tool with adaptive nozzle fittings. Performed with excellence. Highly recommended.

Add throttle lever

9 days ago
Just bought this unit works great. Only improvement would be a throttle lever. Not to happy with the full throttle at start up I like to give the engine a little time to spread the oil around. Especially after the unit has been in storage for awhile. Any chance I can purchase the parts to add a throttle to the unit
