Yes, I've been doing it full time for 3 years and learned that a good surface cleaner and a 6 ft. wand are great time saving tools. Best money I ever spent. Ex: Almost everybody will want you to do their driveway or sidewalks along with the house. Do a driveway by hand and it will take hours and give you a sore back. Use a surface cleaner and it will take 60-90 minutes and do a better job than with a wand. Good surface cleaners last 10 years and have few moving parts to break. New ones cost around $1500 but will pay for themselves in a month. The 6 ft. wand. When cleaning the eaves, soffit and fascia of a house, you have to hit it from several angles to get it clean and a 6 ft. wand saves you from lugging a ladder around the whole house so you can get the nozzle at the right distance to the surface. The area I work in is hilly so many of the lots are sloped and suddenly a house is much taller at one end. Normally, you would need to get a ladder or extension pole. With a 6 ft. wand, you can still reach the area and move on to the next. A 6 ft. wand also has a tendency to keep you drier when working. Ex: when you are cleaning mold from a slab, it's easier to stay dry. 6 ft. wands usually run about $150, but are totally worth it. Get one with a variable pressure handle and it will save the wear and tear on your machine, but specifically the pump. Also, a 12 ft. ladder with a 6 ft. wand will allow you to clean most 2 story houses without having to use a 24 ft. extension pole. Extension poles are great for the abs but it gets old as the summer goes on. I'll be happy to talk with you about chemicals I use, just contact me. No charge.
