1. A vacuum cleaner comprising:
- a first functional unit (2) for providing suction power, and a second functional unit (10) for vacuuming by using the suction power and for coupling electrically to the first functional unit (2);
which first functional unit (2) comprises a first mains voltage terminal (18) and a second mains voltage terminal (20) for receiving an alternating mains voltage, and a first data processing unit (6) having a first reference terminal (26) and a first communication terminal (28);
which second functional unit (10) comprises a first mains voltage terminal (36) and a second mains voltage terminal (40) for receiving the alternating mains voltage, and a second data processing unit (12) having a second reference terminal (44) and a second communication terminal (46);
which first mains voltage terminal (18) of the first functional unit (2) is coupled to the first mains terminal (36) of the second functional unit (10) via a first mains voltage wire (38) and a first mains voltage contact (32);
which second mains voltage terminal (20) of the first functional unit (2) is coupled to the second mains voltage terminal (40) of the second functional unit (10) via a second mains voltage wire (42) and a second mains voltage contact (34); and
which first communication terminal (28) is coupled to the second communication terminal (46) via a communication wire (48) and a communication contact (30) wherein the first reference terminal (26) is connected to the first mains voltage terminal (18) of the first functional unit (2) and the second reference terminal (44) is connected to the second mains voltage terminal (40) of the second functional unit (10).

Abstract
A vacuum cleaner is provided which has a motor housing (2) and a hose (8), which can be coupled via two mains-voltage wires (38, 42), one communication wire (48) and contacts (32, 34, 30). The motor housing (2) and the handle (10) of the hose (8) include microprocessors (6, 12) which communicate with one another via the communication wire (48). The first reference signal (26) of the one microprocessor (6) is connected to the one mains voltage terminal (18) and the second reference signal (44) of the other microprocessor (12) is connected to the other mains voltage terminal (40).
