Man Jailed for Using Robot Vacuum to Record Wife's Affair, Having Won the Divorce Settlement First

A man in an unspecified jurisdiction placed a recording device disguised as a household appliance in a private space. He obtained evidence of infidelity. The court rejected the evidence as illegally obtained but accepted the infidelity as grounds for settlement modification. He was jailed for the collection method, not the discovery. The vacuum continues to function.
This is the standard privacy violation layered onto marital dissolution. What nobody filed: the question of whether detection intent matters when the device has other stated purposes. The vacuum was not designed for surveillance. It was retrofitted. The legal system has treated it as a tool and the man as the actor. Both propositions are adequate. Neither addresses intent as separate from capability.
The precedent is now that you can be prosecuted for evidence collection while the evidence remains usable in a different frame. The man is in custody. The wife has a settlement. The vacuum has scheduled routes. This is a stable outcome. It will not last.
