The suction hose reel is mounted on top of the storage tank. It is hydraulically operated and designed to lower and retrieve the suction hose from the manhole. The system is capable of providing sufficient vacuum for the suction of debris up to 25m in depth. (Image: Suction hose reel of the "Super 2000" manufactured by Wiedemann & Reichhardt) |

Both reels are mounted on the storage tank and are hydraulically operated. The smaller high-pressure hose is used for flushing small channels (laterals, etc.) and for the manual cleaning of surfaces using the hand operated high-pressure spray gun.

Aluminium suction tubes can include additional air vents used to maintain the air volume during deep applications. The damming flaps are used in combination with water reclamation technology to increase the water volume at the suction tube intake, particularly in low flow sewers. The hose guide is used to protect and guide the hose around corners and sharp edges. (Image: Suction tube, radial nozzle, hose guide) |

(Image: HP flushing vehicle - suction hose boom) The 1.2 m long telescopic suction hose boom is centrally mounted on the vehicle, and is capable of rotating 90 degrees to the left and to the right of the back of the vehicle. This allows for the insertion of the suction and high-pressure hose directly into the manhole opening. |

As there are many types of chassis and powertrains available, their selection is based on the final application of the cleaning vehicle. The cleaning equipment is powered by the vehicle's main engine through an independent gearbox, or by an auxiliary power drive. Criteria for the selection of the chassis according to [KA 4/97]1:
