1. An intelligent suction device comprising:
- a motor and a fan connected thereto for generating a suction airflow;
at least one pressure sensor which senses pressure generated by the suction airflow; and
a fuzzy-logic controller which determines at least one derivative of sensed pressure from said at least one pressure sensor and controls said motor responsive thereto.

Abstract
An intelligent suction device, particularly for vacuum cleaners and the like, includes a fuzzy-logic controller for controlling the motor of a fan or turbine. The suction pressure is detected by at least one pressure sensor which feeds back its measurement, in a closed loop, to the controller.
