Abstract: An electrical device, in particular in the form of a suction device (10) or a machine tool, with a housing (20) in which at least one electrical load, in particular an electric drive motor (11D), is arranged, wherein the electrical device has a power supply unit (80) with an energy storage receptacle (81), for the electrical power supply of the electrical load, in particular the drive motor (11D), in the interior of which at least two device interfaces (90A, 90B) for the detachable connection of a respective energy storage interface (190A, 190B) of an electrical energy storage (170A, 170B), in particular a battery pack, are arranged. The device interfaces (90A, 90B) are arranged on opposite side walls (83, 84) of the energy storage receptacle (81), so that the energy storages (170A, 170B) can be arranged on the device interfaces (90A, 90B) with mutually facing bottom walls (175).

Abstract: A suction device with a suction device housing (20), in which a suction turbine (11) for generating a suction flow (S) is arranged, the suction turbine (11) having a suction turbine inflow opening (11A), through which the suction flow (S) can flow into the suction turbine (11) and at least one suction turbine outflow opening (11B), through which the suction flow (S) can flow out of the suction turbine (11), wherein the suction device housing (20) has a suction inlet (12) for letting in the suction flow (S) and a dust collecting chamber (21) for collecting dust contained in the suction flow (S), wherein a filter element (13) for retaining dust in the dust collecting chamber (21) is arranged between the dust collecting chamber (21) and a suction turbine inflow opening (11A) of the suction turbine (11).
