You can control the collection of the cat litter box through the Internet; at the same time, you can also achieve offline control without a mobile phone. At the same time, we have set a child lock in this mode to prevent children from accidentally triggering the machine to run. When the cat approaches the cat litter box, the cat litter box will stop rotating; secondly, it is made of car glass to prevent the cat from being pinched and provide secondary protection for the cat. All functions can be controlled through the device touch screen or App. Using the App for remote control, you can monitor information such as the frequency of use of the cat litter box, the cat's weight, and toileting. Size: large.
