Abstract
A vacuum cleaner with fuzzy control comprises a detector for detecting condition of sucking of dust, such as an amount of dust, a kind of dust and/or a kind of a surface of a floor to be cleaned. A fuzzy inference section responsive to the condition of sucking of dust determines an appropriate sucking force and controls the vacuum cleaner's sucking force through fuzzy inference.
