Abstract: An apparatus and method for cleaning the bottom and vertical side walls of a swimming pool, pond or tank employs a robotic, self-propelled cleaner having a protective housing of conventional design, the cleaner being operated at a primary cleaning speed as it traverses the surfaces to be cleaned and until the cleaner housing emerges from the water along a sidewall of the pool; thereafter the cleaner operates at a secondary drive speed that is relatively slower than the primary speed and the cleaner thereafter reverses direction and descends for a pre-determined period of time at the slower secondary speed in order to permit the air entrained under the housing to escape without destabilizing the cleaner during descent. After the predetermined period of time, the cleaner resumes operation at the more rapid primary speed until the cleaner housing once again emerges from the water's surface, after which the cycle is repeated.

Abstract: The invention is concerned with a device and a method for cleaning and disinfecting medical instruments, in particular instruments of minimal invasive surgery (MIS). Instead of the rigid connection of cleaning tubings to instrument connections and exits which has been used up to now and which have the disadvantage that certain contaminated regions remain inaccessible for a secure cleaning, there is suggested a docking of injector nozzles in defined chronological intervals, the injector nozzles being fixed in a centric position to the openings of the instrument connections. At the same time various types of injector nozzles are applied for adaptation to various instrument connections and openings. By measuring the rinsing fluid quantity flowing to the instrument connections and the total discharging rinsing fluid quantity, the quality of preparation may be evaluated and documented.
