I don't think theres one tool that fits all suites, When I clean a suite I use 4 different tools a 3inch inclosed jet, a 4inch hide-a-hose internal, a 6 inch curtain tool and a 4 inch curtain tool.
at the Cleaning Show I noticed that Ashbys had a good selection of hand tools, they do a nice plastic 4inch internal jet tool that I find very similer to the CFR tool. It has a very large jet so flushes the fabric very well but does'nt have any over spray.
I've said before that all Prochem stuff is over priced, including thier hand tools
