Now that the weather is turning nice and it is getting dark later. The patio was kind of dark. We got a price to pressure wash a section of the grounds that was 1/2 the cost of a Stihl R600.
So we purchased one for the local Ace hardware store. Also got the $150 rotating nossile. which makes the job go much faster. Then I went out and washed the patio, What a difference. Not the fastest job in the world takes about a minute to do 3+ sq ft.
Took about 1 hour for the flag stone and 2 hours for the patio.
You need to be careful with the moss/grass between the flagstone.
They should do this SouthPort. Cleans up nicely. Probably will spend days doing this, every 6 months.
This is something I would like to see Max “The Nasa base” Robot get trained to do.
