The full suction stop product will stop after the water is full. If you don't press it manually, it will keep sucking. The intermittent type of this product is that the first gear is for vacuuming and absorbing water, and it will always suck. In the second gear, it sucks for 30 seconds and stops for 25 seconds. Inhale for another 30 seconds, then stop for another 25 seconds. It is a cyclic process.
