Disclosed are cleaning devices and methods of use thereof for cleaning a vertical stack plumbing system. The cleaning device includes a first cylindrical body defining a first opening for selectively introducing a predetermined amount of cleaning medium into the cleaning device; a second cylindrical body defining a second opening configured to maintain airflow and venting of the vertical stack plumbing system when the cleaning device is in use, the first and second cylindrical bodies being directly connected to a main body of the cleaning device and in fluid communication with one another through the main body; and an attachment member defining a third opening that is directly connected to the main body of the cleaning device, the attachment member configured for direct removable attachment to a plumbing waste pipe in the vertical stack plumbing system and for receiving the cleaning medium therethrough to introduce the cleaning medium into the vertical stack plumbing system.

A control line assembly and technique for fabricating the control line assembly are disclosed. The assembly includes drawn tubular segments through which a gas is flowed to purge contaminants. The outflow of contaminants due to the gas flow is monitored and the gas flow can be controlled and terminated when a sufficient quantity of contaminants has been extracted. The gas flow can be combined with a heat treatment cycle to further extract contaminants. The heat treatment cycle can include multiple heating stages that can be controlled based on the monitoring of the exiting contaminants.

A vacuum cleaner includes a body, an electrically-driven suction unit, a device for collecting dust, a suction channel, a nozzle communicating with the body through the suction channel, an intake device for ensuring an additional portion of air fed into the suction channel and being adjustable between an opened and a closed state, and a control unit for controlling the suction unit. The intake device is bi-directionally electrically connected to the control unit, so that transmission of data or signals between the intake device and the control unit is enabled. The control unit is configured to generate a signal for controlling the intake device in the event of detecting the cleaning start signal or the cleaning end signal. A method for operating a vacuum cleaner is also provided.

A method of removing debris from piping within a high-rise building plumbing network includes inserting a portion of a flexible optical device and flexible water conduit into an opening defined by a plumbing system, the flexible water conduit operably coupled to a water pressure device. The method also includes coupling an end of a vacuum conduit, operably coupled to a vacuum assembly, to the opening and producing an image of a plumbing channel defined by the plumbing system with the flexible optical device. Next, the method includes maneuvering the portion of the flexible optical device within the plumbing system until the image of the plumbing channel depicts a debris at least partially obstructing the plumbing channel, inducing a stream of fluid directed at the debris, and then inducing a vacuum within the plumbing system sufficient to remove the debris from the plumbing system.

The object of the invention is to provide a device which can, with high efficiency, polish and clean the inner surface of a pipe, dry the wet inner surface of the pipe, and perform coating, wherein the device does not require a large pump or a large motive force, and does not require a blast hose or a suction hose. More specifically, provided is an intra-pipe turbine blast system that moves along the inside of a pipe and performs work by spraying a fluid toward the inside of the pipe, wherein: a gas injected from a fluid supply device to the upstream-side end inside the pipe imparts speed to a mixed phase fluid consisting of a liquid and solid particles which are likewise injected into the pipe; the flow speed of the mixed phase fluid is set to 3 m per second which is the critical speed at which solid particles can float without precipitating in the liquid, and as a result of such setting, there is a great effect on reducing the energy required for causing the mixed phase fluid to move; and the mixed phase fluid with such setting is injected at a high speed from a rotation nozzle of a turbine crawler which moves inside the pipe, thereby polishing the inner surface of the pipe, and following the polishing work, the turbine crawler can clean, dry and coat the inner surface of the pipe.
