An apparatus for cleaning the inside of pipes in a heat exchanger is disclosed, which includes an aggregate having the provision of high-pressurized water and, at least, one hose leading from said aggregate for directing the high-pressurized water. The hose is wound around a reel or a retractable feeding device in the aggregate when in a non-operational mode. An operating tube for at least partially containing the hose and being suitable for handling during operation by a user and for directing the high-pressurized water emitted from the hose is further provided. A flexible guide hose is located between the reel of the aggregate and the operating tube with a mounting device for fixing the operating tube in all directions on a frontal side of, at least, one pipe of the heat exchanger allows for a convenient and safe operation by personnel.
