Abstract:
1. A vacuum cleaner having a motor housing provided with an inlet and an outlet, a motor and suction fan unit in the motor housing and arranged to create a suction flow in through the inlet of the motor housing, through the motor and suction fan unit and out through the outlet of the motor housing, holding means for holding the motor and suction fan unit in the motor housing, sealing means arranged to guide the suction flow from the inlet of the motor housing and into the motor and suction fan unit in a sealing manner, wherein: the holding means is arranged to prevent propagation of vibrations originated in the motor and suction fan unit to the motor housing by the holding means responding resiliently to forces from the motor and suction fan unit; the sealing means is arranged to prevent propagation of vibrations originated in the motor and suction fan unit to the motor housing by yielding to forces from the motor and suction fan unit; the motor and suction fan unit is lifted and pressed toward the holding means and an upper part of the motor housing when the vacuum cleaner is turned on; and the sealing means comprises a first annular section sealed against the inlet of the motor housing, a first flexible tubular section extending from the first annular section towards the motor and suction fan unit and forming a hollow space for guiding the suction flow, a second flexible tubular section at least partially radially aligned outside the first flexible tubular section, a joining section connecting a lower end of the first flexible tubular section to a lower end of the second flexible tubular section, and a second annular section extending radially outward from an upper end of the second flexible tubular section.
