A disposable cleaning unit is described herein including an inner receptacle and an outer receptacle.

A lumen inspection device includes an elongate member and a sealing member at a distal end of the elongate member. The elongate member is inserted into a lumen of a medical instrument. The lumen inspection device is translated along the lumen. The sealing member resiliently bears against a sidewall of the lumen as the lumen inspection device is translated along the lumen of the medical instrument. A pressure source is activated to pressurize a region of the lumen adjacent to the sealing member. A fluid property of the lumen is monitored to detect whether the sealing member deforms in response to an obstruction in the lumen.

A system and an apparatus for positioning a plurality of flexible cleaning lances through tubes penetrating a tube sheet of a heat exchanger tube sheet, includes a smart lance tractor drive, a controller, and a tumble box connected to the controller operable to generate and/or distribute electrical power to the AC induction sensor from an air pressure source, supply electrical power to the controller and distribute pneumatic power to pneumatic motors for positioning the tractor drive on the positioner frame. The smart tractor drive includes sensors for detection of mismatch between expected and actual lance positions, sense lance insertion distance and lance removal and provide automated drive reversal operation to remove blockages within tubes being cleaned.

Electrical interference signals are to be eliminated during operation and video quality improved in a metal extension sleeve incorporated in an internal space of a nozzle element of a pipe cleaning nozzle and/or inspection nozzle for contacting an electrical conductor via a camera adapter through the internal space of the nozzle element with a camera module fastened outside the nozzle element. The extension sleeve spans the length of the nozzle element and is releasably fastened form-fit and/or force-fit on the camera adapter and the at least one extension sleeve has coupling threads along the outer surface of the coupling section, with which the extension sleeve is tightened in the internal space of the nozzle element. The metal extension sleeve has an electrical insulation layer made of plastic on its outer surface spaced from the central longitudinal axis, which is applied fully to the entire outer surface without defects.

A sewer cleaning machine includes a power base with a motor and a drive mechanism, and a drum removably coupled to the power base. The drum includes a cable that is selectively extendable out of the drum and is movable between a first position, in which the drum is supported by the power base and coupled to the drive mechanism, and a second position, in which the drum is separated from the power base.
