Which switches would you remove? It seemed like the exact right amount to me if you want to control the pressure, vacuum and heat. Machine looks good.
My machine has none of that crap. light the pilot light, start the engine and clean. near instant 220 heat pressure upto 1500 psi. My machine has been reliable (10 years) and when a issue does arrive its simple to fix. While the owner of that machine is trying to warm it up and figure out which way each of those switches and valves need to go, I will have 2 rooms cleaned :-)
