Abstract: The invention relates to a sewer rehabilitation method, wherein a rehabilitation tool (5) is introduced, by means of a robot (2) that can be moved in a sewer main line (3) of a sewerage system, into a house sewer line (9) leading into said sewer main line (3), rehabilitation work is carried out in the house sewer line (9) by means of the rehabilitation tool (5), and the rehabilitation tool (5) is removed from the house sewer line (9) by means of the robot (2) once rehabilitation work is completed. The aim of the invention is to provide a viable and cost-effective sewer rehabilitation method and corresponding system enabling sewer rehabilitation work being carried out in the house sewer line (9) starting from the sewer main line (3).

Abstract: The invention relates to a device (1) for renovating a pipe, the latter being provided with at least one opening arranged in the wall of the pipe, said device (1) having a base unit (2) that can be introduced into the pipe, a clearing unit (3) that is movable relative to the base unit (2), and an electronic sensor arrangement for detecting the instantaneous position of the clearing unit (3) relative to the base unit (2). To make available a novel device (1) for renovating a pipe provided with at least one opening arranged in the wall of the pipe, which device permits reliable and inexpensive repair of the pipe, the invention proposes that at least one electronic inclination sensor is arranged on the base unit (2).
