Here is another smart litter box that makes life easier for pet parents. The LavvieBot S comes with auto clean and refill function. It uses a rotating rake mechanism to collect waste and has enough space for 3 weeks of waste. The LavvieBot is also capable of refilling litter from its 6.5L storage space.
The PurrSong app connects to the litter box over WiFi and lets you monitor your cat in real-time. You will be able to use it to check litter storage, temperature/humidity, waste drawer status, and other important info. This smart litter box is expected to ship in April.[Source]
