PURPOSE:To restart a motor drive blower used for an electric cleaner inset input state immediate at restarting time by selecting the set input state and the minimum input state, thereby releasing in the minimum input state when the cleaning is interrupted. CONSTITUTION:When a furniture is to be put away in the course of cleaning, a hand is separated from a hose base 5 to be released. Then, contacts (a), (c) become connected state, it is driven by a low input specified by a fixed resistor R16 for inputting the minimum value irrespective of the set value at a variable resistor R1. When a cleaning is started after the furniture is arranged, the hose base 5 is again grasped. Then, the contacts (b), (c) again become connected state, and it is restarted while the set input remains as it is. |
