FIELD: engines and pumps.
SUBSTANCE: electric vacuum cleaner with the closed cleaning cycle and the cooling device, comprising an electric motor with a fan, air ducts with built-in valves, seats for replaceable filters, a dust-collecting brush. The vacuum cleaner is additionally equipped with the engine cooling system comprising a chamber separated from the main volume, with a fan placed therein, an electric motor, a noise-absorbing filter, and air ducts, via one of which ambient air is drawn inside, flows around the electric motor, passes through the noise-absorbing filter, and is expelled via the other duct.
EFFECT: reducing the suction effect of the brushes, low noise level and high cleaning quality make the use of the vacuum cleaner more comfortable.
