Operation of vacuum cleaner with speed control, bag change display and dust bag recognition, reduces suction power when no bag identification is recognized

摘要

When no identification is recognized, the control electronics (17) operate the fan (12) and/or other items to reduce an operational parameter. This reduces dust acceptance by the bag (5) or other dependent parameters. In this way the vacuum cleaner does not develop its maximum power or capability. The control electronics reduce the power of the fan. The vacuum cleaner has a selector capable of reducing fan power independently of any power setting selected by the user.
