Living with it
- Consumables
- PETKIT's manual instructs owners to use only PETKIT's own specialized trash bag in the waste bin rather than a generic bag. petkit.com (manual)
- What consumables cost
- PETKIT sells its own trash bags on its site and lists the Purobot Max Pro/2 among the boxes they fit, so the bags are a recurring purchase on top of the box. petkit.com
- Subscription
- The camera's full HD video playback requires a PETKIT Care+ subscription, which is a non-refundable virtual good that can be moved to another Max Pro unit only once per year. petkit.com (manual)
- Set-up
- To refill litter after the initial setup, owners use the app's Maintenance Mode, which rotates the cylinder so its opening faces straight up for pouring rather than requiring the unit to be tipped or opened. petkit.com (manual)
- Maintenance
- PETKIT's manual frames cleaning as parts-replacement, not just wiping down: it tells owners to regularly clean or replace specific listed components (cylinder, litter sifter, base, sensor, camera, litter pad) for the cat's health. petkit.com (manual)
- Warranty
- PETKIT's warranty policy explicitly voids coverage if the unit is cleaned in a dishwasher against the manual's instructions, alongside accident, abuse, or misuse. petkit.com
- Support and parts
- To open a warranty claim, PETKIT requires owners to go through its customer service team by email rather than a phone line or live chat. petkit.com
- Known issue
- The manual confirms the Max Pro 2 has the same litter-size ceiling as other Purobot models: granules over 12mm long or 3mm across can jam the sifter. petkit.com (manual)
- Safety
- If a cat steps back into the box mid-cycle, PETKIT's manual says the device automatically pauses and issues an alert instead of continuing to run. petkit.com (manual)
- Camera and data
- Outside the camera's scheduled working hours, the manual says the unit records no video at all; owners only get a 5-minute live stream option in that window. petkit.com (manual)
