Mine has a sensor at the top of the waste tank and cuts out when full.
It also used to cut out when low on water but not lately.
To empty the solution tank using the hose there is an override button which switches the vacs back on
but the waste tank must be empty before you override.
The end of the suction hose is about 2 inches from the bottom of the tank so when it cuts out there is still some water covering the elements.
