1. A hand-operated pressurized-fluid device comprising:
a housing structure housing a motor-pump group, the motor-pump group comprising a pump and a motor and the housing structure having a fluid inlet connected to the housing at a suction side of the pump and a fluid outlet connected to the housing at a pressure side of the pump, the fluid outlet constructed on a nozzle unit,
an electrical voltage source, and
at least one operator-control element acting on a power supply of the motor via the voltage source,
wherein the motor of the motor-pump group is a brushless direct-current motor and the pump is a wobbling-rotor pump having two toothed plates, each respectively provided with a corresponding annular spur gearing, wherein numbers of teeth of the two spur gearings meshing with one another differ by one from one another and the toothed plates are disposed at an angle to one another and wander relative to one another in such a way that the spur gearings bound several pump spaces that become larger and smaller during pump operation.
