This pricey, cordless robot is essentially a shiny, high-tech Roomba for your above-ground pool, assuring its owners that they have transcended the barbaric chore of vacuuming. Apparently, nothing validates your new 'global citizen' status like the ability to point at your filtration system and whisper, 'My pool is *self-maintaining*.' It will inevitably fail in Baja because the combination of salt spray and the occasional swarm of aggressive, iridescent beetle will short-circuit its supposedly 'elite' sensors within 72 hours.
