This ridiculously over-engineered robotic pool scrubber is marketed to convince fresh-money spiritualists that their mere presence requires automated, high-tech water purification. Buying the Aiper S1 Pro makes you feel like the intellectual elite who doesn't scrub grout with their own hands, thus signaling a superior understanding of leisure. However, in the arid, salt-crusted drama of Baja, its delicate electronics will simply fuse to the mineral buildup, creating nothing but a very expensive, inert piece of underwater garbage.
