Ideally, I'd like to see a match up between a Cimex and a Brute. And also a match up between a Bissel, a Rug Doctor and a couple of other Porties plus a
Vortex, Stanley Steamer, a Chem Dry, a Bane, a Nordic 1 and any other tms that show up.
Unlike the CRI testing each unit will have a set time limit to show what they can do and all units will use the exact same pre-spray and no other accessories or steps will be used except using their own wands, heat and flow. Naturally this will favor the larger units which should be expected to do more in less time. Next year we can use a different set of criteria, like 2 - 3 times more time for a Porty than allowed for tm etc.
Each sample of carpet will start out weighing the same and will be cleaned for the same amount of time and weighed again. This will give a false reading as this weight will also include any water left by the cleaning process. The next day each sample will be weighed again (dry) which will tell us how much water was left in after cleaning and how much dirt ( by weight ) had been removed by each cleaning unit.
