FIELD: personal use articles. ^ SUBSTANCE: invention is related to the vacuum cleaner and method of cleaning the vacuum cleaner filter with sediment pan which has a suction inlet opening and through at least one filter and at least one suction pipe is connected to the flow with a suction unit, and with at least one that ends lower downstream from at least one filter in the suction pipe with inlet of the outside air, which is made with the possibility of closure by at least one check valve. At least one check valve has a valve body made capable to make reciprocating movement between a closed position in which it is adjacent to the valve seat and an open position in which it is separated from the valve seat. The retention force is applied to it with a closing spring, and in the closed position additionally magnetic is applied to it with the magnetic holder. For cleaning at least one filter at least one valve is open, and on the outside air is supplied to the opposite side of the sediment pan of at least one filter. After switching-off at least one suction unit at least once is opened and then at least one valve is closed again, and at least once the outside air is supplied to the opposite side of the sediment pan of at least one filter. The magnetic holder is equipped with an electromagnet, which is supplied with current for closing the shut-off valve. When the suction unit is turned off, simultaneously the power of the electromagnet is cut off. In the vacuum cleaner the shut-off valve is made with the possibility of at least a single automatic opening and a subsequent closing after turning off the suction unit, and it has an opportunity for at least a single supply of outside air to the opposite side of the sediment pan of at least one filter. Electromagnet of the magnetic holder is made to provide it with the current for closing shut-off valve. When the suction unit is turned off, the possibility of simultaneous shutdown of electric power supply of the electromagnet is also provided. ^ EFFECT: improvement of cleaning efficiency of at least one filter. ^ 22 cl, 3 dwg |
