The cyclical suction system generates an intermittent cyclically spaced cyclical suction pressure waveform of a vacuum pressure below atmospheric pressure and a positive pressure above the vacuum pressure. The system includes a flexible inlet tubing connected in fluid communication between a vacuum pump and a suction conduit. A positive pressure pulse generator mechanism intermittently cyclically applies an external force that compresses the segments of the flexible inlet tubing, thereby reducing the internal volume and displacing fluid that can be collected therein, thereby generating positive pressure pulses. Upon withdrawal of the applied external force, the flexible inlet tubing is configured to be able to be forced to return to an uncompressed state, thereby increasing the internal volume while reducing pressure therein until the vacuum pressure ultimately regenerates, thereby minimizing return time and maximizing cycle frequency.
