Another State heard from.....I bought a Husquevarna 3300.....I use it occasionally, sidewalks in spring, shoot the tractor, and about every third year the house which is two story. Its worked well for me. I think I paid out like 600 for it. Your use sounds to be more than occasional so this may have zero bearing. The other piece of information is the use to blast off grease. It does remove grease but not completely. I would think a hot water version would be what you are looking for there. Again, Im not using it commercially.
