Taipei: In a bizarre case of household technology backfiring, a man in Taiwan who used a robot vacuum cleaner to gather evidence of his wife’s infidelity has found himself behind bars. While the secretly recorded footage helped him win a civil lawsuit against his spouse, a criminal court subsequently sentenced him to prison for severely violating her right to privacy.
The marital dispute began in September 2023. The husband, who had been married since 2021, discovered a recently used toothbrush at the couple’s secondary holiday home. His suspicions were further fueled after reviewing parking garage CCTV footage, which showed an unidentified man dropping his wife off at the property.
Three months later, the husband remotely activated their robot vacuum cleaner from his mobile phone. Initially intending to use its built-in audio feature to communicate with his wife, he was instead met with a live video feed capturing her in a compromising position with the suspected lover. The footage showed the pair embracing and walking around the house unclothed. The husband immediately recorded the feed to build a legal case.
Armed with this digital evidence, he filed a civil lawsuit against his wife and her partner, demanding 2 million New Taiwan Dollars (approximately $68,000) in damages for the violation of his marital rights. A civil court ruled in his favour, concluding that the relationship had clearly surpassed normal friendship, and ordered the accused pair to pay him 500,000 NTD in compensation.
However, the legal victory was short-lived. The wife retaliated with a criminal countersuit, accusing her husband of recording her most intimate moments without her consent. During the trial, the husband argued that his actions were legally justified because the civil court had already accepted the footage as legitimate evidence.
The criminal court firmly rejected this defence. The judge stated that entering into a marriage does not strip an individual of their fundamental right to privacy. The court noted that the vacuum’s standard operational lights and sounds did not constitute the wife’s consent to being filmed.
As a result, the husband was sentenced to five months in prison and fined 150,000 NTD for illegally recording private activities. Under Taiwanese law, secretly recording and retaining intimate information without consent carries a maximum penalty of up to three years in prison and a 300,000 NTD fine.
