Patent number: 11284613Abstract: A water animal deterrent is disclosed herein. The water animal deterrent includes an animatronic spider having moving legs, multiple lights, Bluetooth speakers, and motion detectors, where the device is powered by a rechargeable battery and solar panels. The water animal deterrent is placed near a swimming pool to protect the pool against various vermin that may come into contact and contaminate the pool. The motion detectors of the water animal deterrent detect the presence of any vermin that walks by a swimming pool. If vermin are detected, the legs of the animatronic body begin to move, and the lights begin to illuminate. As a result, the vermin in the vicinity of the swimming pool are scared away. The water animal deterrent further includes a Bluetooth speaker to facilitate a noise to scare the vermin away. The speaker may also be used for entertainment purposes.Type: GrantFiled: December 11, 2019Date of Patent: March 29, 2022Inventor: Michael Middleton
