SUBSTANCE: cleaner is designed for wet and dry cleaning the uncovered floor surfaces. The cleaner contains the control lever pivotally connected to the bottom, return system with wet and dry cleaning suction nozzles mounted on the bottom, wet and dry dust return tank, control air duct started from each dry cleaning suction nozzle and wet cleaning suction nozzle to the return tank. The control lever or the bottom accommodates the mounted electromotor/fan assembly to generate control air flow in the control air duct, at least, from dry cleaning suction nozzle or wet cleaning suction nozzle to the return tank. The control air duct starts from each dry cleaning suction nozzle and wet cleaning suction nozzle to the return tank. The control air duct contains the mounted deflector moving between dry cleaning suction position and wet cleaning suction position for selective, at least, partial blocking of the control air flow from wet cleaning suction nozzle and dry cleaning suction nozzle, respectively to the return tank. Besides there is a mounted mechanism connected with the deflector on the control lever to enable the deflector to move between dry cleaning suction position and wet cleaning suction position. According to the performance version the cleaner contains the initiator mounted on the bottom and moving vertically between low position for contact interaction with the cleaned surface and lifted position over the cleaned surface for selective excitation. The cleaner can contain the cut-off valve mounted in the return tank and used to prevent hydrodynamic connection of electromotor/fan assembly and the return tank if liquid level in the return tank reaches the first preset value once the control lever is in the first position forward from the vertical position, and the second preset value different from the first one once the control lever is in the second position back from the vertical position. According to the performance version provided, the cleaner is supplied with bothway holder on the control lever, with the first part adapted for convenient holding with the user hand as the control lever is in dry cleaning suction position, and the second part adapted for convenient holding with the user hand essentially in the similar relative position as the control lever is in wet cleaning suction position.

EFFECT: improved convenience in using the cleaner with simplified design and without auxiliary means.
