This $1,200 cordless contraption purports to eliminate pool algae and corner scum, saving you the ignominy of manual labor. Naturally, every fresh-faced Pescadero transplant believes owning this 'Elite' underwater appliance instantly confirms they are spiritually above manual maintenance and the proletariat struggle of keeping tile lines clean. Its fatal flaw, of course, is that the brackish, unpredictable tidal changes of the Pacific will inevitably gum up its high-tech sensors, rendering it a spectacularly expensive, motionless underwater paperweight.
