It is also possible to turn on the LEDs 55 and 55 when the power nozzle 5A is used, assuming that the nozzle portion 26 is installed forward in the traveling direction.
As described above, when the illumination body (LED 55) capable of irradiating the front of the power nozzle 5A is provided, cleaning in a dark place can be easily performed. The number and position of the LEDs can be changed as appropriate, and only one LED can be provided at the center of the nozzle portion 26 or can be provided downward to the cleaner body 2. Also, the timing of lighting the illumination body is not limited to when the power nozzle is used, but may be turned on when not in use. It is also possible to provide an ON / OFF switch dedicated to the lighting body.

Further, as in the cleaner 1B shown in FIG. 13, sensors 57 and 57 (non-contact type such as an infrared sensor) for detecting the sucked dust are provided at positions near the rear part in the nozzle 3. When dust is detected, the LED 58 provided on the front side of the handle 10 may be turned on.
Thus, if the detection means (sensor 57) for detecting the suction of dust and the notification means (LED 58) for informing it are provided, the user can be notified of the presence or absence of dust, and efficient cleaning becomes possible. . In addition, the position of LED can be changed suitably, may be provided in a power nozzle, and can also serve as the illumination body demonstrated in FIG. The detection means can also be provided on the power nozzle side.
In addition, when the detection unit detects the suction of dust, the control circuit board 18 may perform control to increase the rotation speed of the brush motor 45. In this way, dust can be collected efficiently.

In addition, a negative ion generator may be provided in the power nozzle to generate negative ions in conjunction with the rotational drive of the brush 47. In this case, the negatively charged ions are combined with the positively charged dust and neutralized, so that the dust is easily separated from the floor surface and the dust collection efficiency is increased.
These modified examples can be implemented in combination.
