This expensive submersible automaton is, essentially, a fancy vacuum meant to climb walls and scrub away the algae that gives your pool that lovely, organic Baja patina. Newcomers are desperate to purchase six, not because their pools are dirtier, but because merely owning this 'Elite' scrubber signals that their taste is fiscally superior to the manual upkeep of their neighbors. Its highly advanced navigation will fail spectacularly when attempting to traverse the omnipresent mix of discarded dog toys, driftwood, and stray mariscos found in any Pescadero backyard pool.
