Oil-Free Electric solar powered pressure washer for Ross Allen Island Boardwalk in Silver Springs

The boardwalk in Silver Springs in Florida needs cleaned, I imagined they didn't want to bring gas and oil powered equipment because they don't allow boats of that type anywhere near the silver springs area. The solar panels weren't on there at the moment but the Ecoflow solar generator was powering the 600watt electric power washer and electric water pump for gas and oil free environmentally friendly pressure cleaning. I would use two solar generators, 1 charging while the other was being used, and remotely charge the solar generators to use at a big area like silver springs in Florida. This could be designed with solar panel racks to charge while being used. This is my own design, not currently being used by any company, I can sell this setup for $3,000 with one solar panel and generator. I can also put it on a UTV or Lawn Utility Trailer which would be better for boardwalks for only $2,500. They should use an electric golf cart to pull it to be 100% environmentally friendly. Would be good to go around and pressure clean the boat ramps around the river while they are at it.
