I haven't had an opportunity to use a
CRB, but I have used other variations of machinery to encap. Cimex with a variety of pads and brushes, rotary scrubber both pre-spray and shampoo tank delivery with a pads, bonnets, brushes, an orbot with a variety of pads etc. There are pro's and con's to each system. In terms of cleaning power, the cimex with shampoo tank delivery of product delivers the best cleaning results, but it's not always the quickest or best solution, and will not always leave the carpet the driest. Pads tend to deliver the best shear, brushes tend to distribute product best product distribution, bonnets recover soil. Spraying gives better control of moisture, shampoo tank delivery is a hell of a lot quicker. Rotary's will smack a cimex around in terms of productivity time if you have desks and tight areas, but won't give the same uniformity or clean. An orbot delivers very uniform cleaning, more maneourvable than a cimex, but not nearly as quick as a rotary. I suspect a
CRB would deliver better cleaning over the verticality (is that a word) of the pile, and lift/recover deep embedded dry soils. But how many commercial carpets have that much in the way of pile? Not too many where I am located.
