| description | PROBLEM TO BE SOLVED: To provide a vacuum cleaner with an excellent automatic running function, capable of lightly starting the automatic running. SOLUTION: The vacuum cleaner includes a running roller 10 for moving a vacuum cleaner body 1, a driving motor 14 for driving the running roller 10, an encoder 12 for detecting the direction and/or frequency of rotation of the running roller 10, and a control means 20 for feeding the electric power (or voltage) to the driving motor 14 according to a signal from the encoder 12. The control means 20 increases the electric power (or voltage) to be fed when there is no rotation detection signal from the encoder 12, and reduces the electric power (or voltage) to be fed when there is a rotation detection signal, so that the critical power (or critical voltage) for the vacuum cleaner body 1 to start running or not is continuously or intermittently fed to the driving motor 14. Accordingly, the vacuum cleaner body 1 is always in the critical state whether to start running or not, and therefore, the vacuum cleaner body 1 can start automatic running just as a user applies only a small tension to a hose.
