[0012] To this end, the present invention relates to a vacuum cleaner comprising:

[0013] - a main body comprising a suction nozzle arranged in a front part of the main body and through which air is capable of being sucked in by the vacuum cleaner,

[0014] - a gripping handle mechanically connected to the main body, the grip of grip being elongated and having a median longitudinal axis,

[0015] - a waste separation and collection device fluidly connected to the nozzle suction, the waste separation and collection device comprising a receiving compartment provided on the main body and comprising an access opening, a vacuum cleaner bag, also called a dust bag, configured to be housed at least partly in the receiving compartment and to be introduced into the receiving compartment via the access opening, and a closing hood mounted to move relative to the main body between a closed position in which the closing hood closes the access opening and delimits, with the receiving compartment, a suction chamber, and an open position in which the closing hood releases the access opening and allows insertion or removal of the vacuum cleaner bag into or out of the receiving compartment, and
