BFN,
The Kleenrite swivel-head was long considered the 'Rolls Royce' of upholstery tools. The enclosed jet is in chamber one, the next three chambers are suction, separated by walls terminating in roll-bars.
This design gives a moderately deep injection of fluid, then corrugates the cloth whilst applying some squeegee action from the three roll-bars.
The tool comes with a swivel-attached 4' suction hose, enclosing the solution hose.
Since changing my main upholstery tool to a CFR Combi, unlike many, I have not noticed any improvement in drying times. to me this indicates that, used to its' best advantage, the Kleenrite is capable of an extremely high level of extraction.
John.
