Systems and methods for maintaining pool systems

A system comprising:

• a liquid filter configured for fluidic communication with a fluid repository;
• a flow sensor in fluidic communication with the liquid filter;
• a variable-speed pump in fluidic communication with the liquid filter and the flow sensor;
• and
• a processor in electronic communication with the flow sensor and the variable-speed pump, the processor configured to:
• determine a total volume threshold for a filtration procedure of the fluid repository;
• identify a set of fluid flow activities performed by the variable-speed pump;
• determine a remaining volume for completing the filtration procedure by reducing the total volume threshold by a volume of fluid moved by the variable-speed pump during the set of fluid flow activities;
• identify a pattern of heating procedures conducted by a heating element in fluidic communication with the liquid filter and the variable-speed pump;
• and
• determine, from a set of energy-expenditure factors comprising at least the pattern of heating procedures, and the remaining volume, an activation schedule and an activation power output of the variable-speed pump for completing the filtration procedure.
