The vehicle (1) has a wheel assembly (6) with two wheels (7) that are in contact with a narrow lower part (F) of a sewer pipe (3), where the wheels of the assembly are oriented in a same plane (P1). A stabilizing unit (20) is arranged with a stabilizing wheel (24) that is oriented in another plane (P2), where the latter plane is inclined with respect to the former plane. The stabilizing wheel is arranged to be in contact with a side wall (L) of the pipe. A drive unit i.e. motor, is arranged to rotate one of the two wheels.
