Wasn't Prochem's 4 jet like that too? I like the way Sapphire made the connector on their upholstery tool so it's doesn't matter if I want to connect a 1 1/2 or a 2 inch to it. It's ready for either one and I find that pretty handy. I do use about a 6 ft. whip and probably will until I retire. I tried the 2 inch hose to the tool thing and just hate it even though I can see some slight advantage to it.
