The man from Taoyuan, Taiwan, was sentenced to five months in prison for unlawfully recording intimate images.
His suspicions eventually led to a discovery on Christmas Eve. The husband accessed a robot vacuum at the property remotely through an app, intending to communicate with his wife using the device.
Instead, its live camera showed that another man was there, and he then activated the recording function, capturing footage of the two together.
It wasn't for catching her cheating, it was for unlawfully recording her having sex.
