Mobile nozzles and associated systems for cleaning pools and spas are provided. One or more mobile nozzles traverse a pool or spa, dislodge settled debris from the floors thereof, and direct the debris to one or more outlets for removal and/or filtration. Each of the mobile nozzles can include a body, a water intake, a discharge nozzle configured to expel pressurized water, one or more sensors adapted for navigation and/or to locate debris within the pool or spa, a propulsion system, and a control system including a memory and a processor. The discharge nozzle can be movable between a plurality of orientations relative to the body, or can have a fixed orientation. The processor is operable to identify debris in the pool or spa and cause the discharge nozzle to be positioned such that the pressurized water expelled therethrough directs the debris toward a debris collection zone or outlet.

A modulating heater system for a pool or spa includes a pool or spa heater capable of variably modulating energy output thereof and a controller communicatively coupled thereto. The controller determines a predicted load based on a previous load, ambient and water temperatures, and estimated pool/spa size, and determines an overshoot setpoint for an operational mode. The controller establishes a target temperature setpoint for the mode and receives a current water temperature. The controller determines whether the overshoot setpoint plus target temperature setpoint is greater than the current water temperature, and determines an error based thereon. The controller determines if the error is less than or greater than a target for the mode, and, based on this determination, determines a heater modulation rate for the mode taking into account the mode, maximum heater output, and available fuel supply. The controller controls the heater to operate at the determined modulation rate.

Debris filtration and strainer systems for a fluid handling device are provided herein. The strainer systems can include one or more of a strainer basket, a removable insert, and an adapter for removably engaging the removable insert with the strainer basket. The removable insert includes a liner having a plurality of openings that are the same size as, or smaller than, the openings of a the strainer basket, and which is inserted into the strainer basket to capture debris from water passing therethrough, preventing clogging of the strainer basket and reducing the frequency of cleanings of the strainer basket. The liner can be fabricated from a biodegradable material, and thus can be easily removed, disposed of, and replaced. The removable insert can include a rigid connection tab with one or more features for removably engaging the strainer basket and/or an adapter positioned between the strainer basket and the removable insert.
