Taiwan Man Uses Robot Vacuum Camera to Prove Wife's Affair, Wins Compensation but Receives Prison Sentence for Illegal Recording

A resident of Taiwan used the built-in camera of a household robot vacuum cleaner to gather evidence of his wife's alleged infidelity, ultimately winning monetary compensation while himself facing criminal penalties for unauthorized recording.

The man grew suspicious after finding an unfamiliar toothbrush in the couple's countryside residence. Footage from a parking area camera revealed an individual who had previously driven his wife home. Three months later, while attempting to connect with his spouse via the vacuum cleaner's mobile application, he observed the same visitor through the device's live video stream.

The camera captured the wife changing clothes, lying in bed with the man, and walking naked through the house. The owner saved the recordings and submitted them to court as proof of the affair. Although infidelity itself is not a criminal offense in Taiwan, violations of spousal rights can justify financial compensation. The husband initially sought 2 million Taiwanese dollars but was awarded 500,000 — roughly $19,000.

The wife responded with a counter-suit, stating that the intimate footage had been obtained without her consent. She noted that the vacuum's sensors and indicator lights provided no clear signal that recording was underway. The husband argued that the court's acceptance of the video in the civil proceeding rendered it admissible, yet the judges rejected this reasoning.

While the recording could be used in the civil matter, the unlawful acquisition method remained a separate violation. The court determined that the right to privacy held greater weight than marital duties. Consequently, the man received a five-month prison sentence and a fine of 150,000 Taiwanese dollars — equivalent to 30 percent of the compensation he had received.
