Poolmate Hydro 4 Battery Powered Robot Pool Cleaner, with WiFi

The Poolmate Hydro 4 is a battery powered robotic pool cleaner with WiFi, part 40.40.300.0003.

It runs on its own battery rather than a cord back to a power supply, and Poolmate pairs it with a floating battery pack. The WiFi lets the cleaner be controlled from an app instead of only at the unit itself.
