This $1,200 cordless contraption is essentially an underwater Roomba that promises to automate the scrubbing of dead algae, thus providing the newly arrived expat with an instant, visible sign of 'luxury competence.' It signals that you are not merely a tourist, but a financially stable, maintenance-averse Renaissance Prince. However, attempting to navigate the unique mixture of Pacific salt, spilled ceviche, and low-tide driftwood in the Pacific will undoubtedly cause its 'industry-leading' sensors to commit a catastrophic, watery ballet dancer-style malfunction.
