Claim 16:
17. A system for collecting liquid, the system comprising:
a controller;
a pump body mechanism communicably coupled to the controller and configured, in response to a command of the controller, to:
collect the liquid into a cavity of a suction tube assembly; and
delivering water into the cavity to clean the cavity; and

a liquid-level sensing mechanism communicably coupled to the controller and comprising a touch chip, the liquid-level sensing mechanism configured, in response to a command of the controller, to:
determine whether an amount of the liquid collected in the cavity reaches a threshold based on a change in an input capacitance of the touch chip; and
control a start and a stop of collecting the liquid in response to the amount of the liquid collected in the cavity.
