I just picked up the 2000 psi electric washer from Lowes made by Greenworks

for the Foam Cannon I use an MTM model made specifically for lower pressure electric power washers... just need to pick up a quick release adapter for it

The reason I got an electric specific cannon is because it is designed for lower pressure while still providing a good amount of foam. There are youtube videos that compare the two mtm models on an electric washer. If you get a gas specific one (which is pretty much every other foam cannon... it ends up being more runny and less foamy)
My routine consist of
1) Sonax the wheels and use the pressure washer to rinse off after 5 minutes
2) use the pressure washer to rinse any debri/ bugs/ tar off the car
3) Fill my Foam Cannon with water + 2 to 4 oz of Honey dew Snow Foam and spray onto the car
4) let it dwell for 5 to 10 minutes
5) Rinse off with the Pressure washer
6) Since I am trying to save water (and the pressure washer uses 80% less water than a conventional wash)... I just finish the car off with a rinseless wash solution and 2 bucket method using either Chemical Guys Rinseless wash which they unfortunately don't make anymore or Optimum No Rinse
7) Quickly spray on some V07 detailer to take care of any spots I missed
this whole routine takes me about 45 min to an hour
I plan to just do a full foam cannon wash maybe once a month to once every other month and still continue to use my waterless washing methods in between unless it is really soiled.
