I have the Greenhorn,
Prochem Ti and a Joe's imitation greenhorn wand.
- The green horn cleans very well, built well- Heavy though.
- The Joe's wand cleans well though the variable shear is connected to the wand very flimsily, it bends out of shape. Just cheaply done. The idea of the movable shear sounds good, the execution unfortunately is not. I hardly ever use it.
- The Ti is a great wand. Cleans well, built well. Very light and has the lowest profile, so it can get under the lowest furniture. One thing I had an issue with was that it developed a crack where the trigger valve is connected to the tube. They have a new fitting for it, though to pay more $$ at that price feels like an insult.
The Ti wand is the one that always comes out of the van.
Not sure why Larry makes a point about using a different wand for a portable. I understand the principle of using a smaller wand in order to increase suction. However, I use the Ti wand 14" on all my portable jobs (Mytee 2x 3 stage vacuum, usually 50, sometime 75 feet length of 2" hose) without a single problem. Works great.
P.S. For durability and reliability, nothing and I mean NOTHING compares to the HydraHoe.
