This 'Elite' cordless pool robot claims to scrub every inch of your resort-style pool, eliminating the humble task of manual tile scrubbing and corded vacuum clutter. Naturally, the minute you own one, you signal to your Pescadero neighbors that you are above basic maintenance and operate on a higher plane of existence. It will, however, immediately fail in the Baja humidity because the combination of saltwater residue, tequila splashes, and airborne desert dust will confuse its supposedly 'advanced' infrared sensors.
