    摘要： In a vacuum cleaner, both static pressure H data and a variation width ΔH in the static pressure appearing when a suction port is operated are detected from a pressure sensor (8) provided at a rear side of a filter (7) within a main body (2) of the vacuum cleaner; a current variation width Δpbi appearing when the suction port is operated is detected from a current of a nozzel motor (26) for driving a rotary brush (10) stored in a power brush suction port; an air quantity at the suction port is calculated from the current, rotational speed of a fan motor (FM) and static pressure ; command values are newly obtained by performing a fuzzy calculation with the variation width Apbi, static-pressure command value Hcmd ; the variation width ΔH and the static-pressure command value Qcmd ; the variation width Δpbi and static-pressure command value Hcmd ; and also the variation width ΔH and static-pressure command value Qcmd as the input thereto ; the rotational speeds of the fan motor (FM) and nozzel motor (26) are controlled from the result of the command values ; and further optimum air suction force is automatically obtained, depending upon the suction port under use and cleaning floor plane.

    摘要： When detecting a fault of a master control device 20, a slave control device 30 refers to master-device-line information, and obtains line information to establish a connection with the other master control device 20. The slave control device 30 transmits connection request information to the master control device 20 extracted from the other master control devices 20. The other master control device 20 determines whether or not it is connectable with the slave control device 30 that has transmitted the connection request information, and transmits a determination result as connectability information. The slave control device 30 switches a communication line to the other master control device 20 when the received connectability information indicates the connectable status.
