may be carried out through the utilization of a smaller quantity of liquid dye in the event a particular area of the carpet being dyed is overly wetted the valve 76 may be momentarily closed by the operator and the wand assembly 14 may be moved in a forward direction as illustrated in fig4 a back over the same path of the carpet 86 which was previously vacuumed this will enable the vacuuming operation to thoroughly vacuum the excess liquid dye from an overly wetted area of the carpet in addition forward movement of the wand assembly 14 restores the nap of the rug to the original condition thereof if it is desired the discharge from the 100 psi pump 52 may pass directly to the supply line 70 and a separate 50 psi pump not shown including a suction line therefor extending down into the bucket 40 may be provided with the discharge of such a 50 psi pump connected to the inlet 62 of the heater 50 and the outlet 64 of the heater 50 discharging back into the bucket 40 in which instance the valve 68 may be eliminated further the interior of the bottom of the well 20 includes a pair of spaced insulatively supported contacts 90 which if bridged by an overflow of liquid dye into the well 20 will operate to terminate electrical actuation of the vacuum 44 heater 50.
