ABSTRACT:
An apparatus for cleaning tubes which apparatus comprises a hollow barrel which is connected to a primary drum containing a coiled resilient tape so that the tape may pass from the drum along and out of one end of the barrel, an electric motor operatively connected to an inner end of the coil of tape and arranged to rotate the coil of tape and to drive the tape out of the barrel and to retract it into the drum, a cleaning device such as a brush attached to an outer end of the coil of tape, and a vacuum hose connected to the other end of the barrel and adapted for connection to a vacuum generating apparatus to create suction at said one end of the barrel, in which apparatus there is provided associated with the drum and the coil of tape a proximity switch sensor and a plurality of targets adapted to be sensed by the proximity switch sensor, relative rotation between the sensor and the targets causing the sensor to transmit impulses to a visible display device to indicate the amount of tape unwound from the coil.
