AquaCal's inverter heat pump line, in three sizes: the T70, T100 and T130. An inverter compressor varies its speed to match demand instead of switching on and off at full power, which is what makes these quieter and more efficient than a fixed-speed unit. Choose the model by pool volume and by how much of the season you want to swim.

The AC1500 PRO, a cordless robotic cleaner that runs on its own battery rather than a hose or a booster pump. It cleans floor and walls, and needs nothing plumbed into the equipment pad.
