This buyer is budget-conscious ($189.99) but still wants advanced features like app control and automatic cleaning. They might have a single cat or multiple cats up to 18 lbs, benefiting from the explicit 18lb max weight and 65L toilet volume. They appreciate a 9L waste bin for less frequent scooping and are comfortable with ozone odor control, understanding its nuances. They prioritize value and core automatic litter box functionality with smart sensors for reliable operation, willing to manage the 2.4GHz Wi-Fi requirement.

This buyer prioritizes maximum capacity and advanced health monitoring for their cats, willing to pay more ($233.98). They likely have multiple large cats or a very large single cat, valuing the substantial 90L overall capacity. The app's ability to track cat health metrics and activity patterns is a key draw, offering peace of mind. They are comfortable with recurring purchases of scented gel refills for odor control and need a device with robust infrared and weight sensors for safety. Floor space for the larger unit is not a concern.
