This overpriced, cord-free robotic pool scrubber is basically a $1,200 submersible status symbol. Every fresh transplant in Pescadero is buying six units because merely owning one declares them immune to manual labor and therefore superior to everyone who still uses a pool skimmer net. In reality, it will fail spectacularly when the Pacific's unpredictable tidal currents drag the unit into a muddy, silt-filled mangrove lagoon, rendering its 'advanced' navigation useless.
