If you plan is to clean on yachts then you have two choices.

 

Buy a powerful unit or use your Recoil and have it sit on the dock and take the long hoses into the yachts. As far as heat is concerned you may mess up the docks electricity for other boaters since you will require at least 3 cords. Forget propane around boats and inside buildings. In fact, you may never get insurance. Even in large boats you will find that any powerwand you mentioned will be too large and awkward.

 

The Mytee II with the heater would be good for your upholstery cleaning, but make sure you use a Stealth Dry Tool with it or any other fast-dry tool you mentioned. I say stealth because it is more than adequate and is much less expensive than the others but all you mentioned are superb in both cleaning and drying and less or no overspray. Sounds like you are a candidate for a truckmount but I realize people must crawl before they run unless someone else is spending the initial start-up money.

 

You must know by now that a truckmount will give you all you are looking for and then some. The problem you are creating for yourself is that you are attempting to generate truckmount power with a portable and doing so will force you to use excessive electrical power and you may be doing things that are illegal, unsafe and downright dangerous. You should look at the line of wands that Powerflight sell or are also called CFR. You can see them here.

 

P.S.

You can choose to use both the CFR Special Purpose Hand Tool and the Hard Surface Hand Tool. You could clean a boat very fast and successfully regarding drying. It would mean hands and knees but worth it and you could offer HAND-CLEANING. The wealthy boaters would eat this up and have something to talk about to their snobbish friends. It would all be in the name of FREE ADVERTISING for you.

 

Good Luck!

 

 

Ted, I've always been interested in their tools,  but I've never held their wand or known anyone who owns one. You sell them, so obviously you like them, but what's the pos. and neg. feedback you get about them?
