PETKIT Purobot Ultra camera missing: clean the pogo pins and bring the AI camera back online
- Dirty Pogo Pins — The modular AI camera communicates with the main unit via exposed metal pogo pin contacts. Cat hair, dust, or humidity on these pins blocks signals, causing a false "Camera missing" error. Cleaning the contacts with a dry cotton swab restores connection.
- Litter Dust Obstruction — Fine clay litter dust accumulates in the camera's rotating base track, jamming the motorized gear joint. Cleaning the track with compressed air or a soft brush releases the gear lock.
- Loose Camera Seating — If the four hex screws holding the camera module are not tightened fully, the module shifts during litter box rotation, causing the pogo pins to lose contact. Reinstalling and tightening all four screws firmly resolves the issue.
- Firmware Lockout — Power-cycling the main unit by unplugging it for 30 seconds restarts the camera micro-controller and restores connection parity.
- "Camera missing" warning — The PETKIT app displays a persistent error stating the AI camera is disconnected or missing.
- "AI Camera offline" warning — The app reports the camera is offline, and the live video feed is completely black.
- Stuck rotation — The motorized camera module fails to rotate automatically, stops mid-cycle, or gets physically jammed.
- LED misalignment — The physical power indicator light on the camera module glows solid green, yet communication with the litter box remains broken.
Your cat may have no usable box right now. Cats that can’t get in will hold it or find another spot in the house — put a spare tray down before you start, so nothing depends on how fast this goes.
Why the AI camera goes offline or gets stuck
The Purobot Ultra's AI camera is a highly specialized modular hardware component designed to be removable. While this allows for easy cleaning, it introduces mechanical tracks and electrical contacts that are vulnerable to the high-dust environment of a cat litter box.
Particulate Ingress on Pogo Pins
The AI camera module communicates with the litter box mainboard via gold-plated pogo pin contacts. Because clay cat litter produces fine, airborne dust, particles and pet dander easily settle on these gold contacts over time. This layer of dust, combined with room humidity, insulates the electrical path, causing the main unit to report that the camera module is completely missing or offline.
Litter Accumulation in the Rotating Track
To track your cat and inspect waste, the camera rotates 180° on a motorized track. When your cat exits or when the cylinder rotates, clay granules can fall into the camera's rotating base track, wedging inside the gears. When the motor tries to rotate the camera, the resistance triggers an overcurrent safety shut-off to protect the motor, causing a camera stuck warning in the app.
In most cases, following the structural checklist below will fully restore the camera's physical and electrical connection in under 10 minutes.
How to fix it — step-by-step
Work through each step in order to clear dust, clean contacts, and properly secure the modular camera. Never use liquid cleaning solvents, alcohol, or water on the gold pogo pins—liquids will corrode the gold plating and permanently ruin the connection.
Still failing after completing all maintenance steps? The internal wiring or pogo pin springs may be permanently worn—see the replacement options below.
Optimise Purobot Ultra Odour and Waste Control
Ensure continuous automatic bag sealing and RFID scanning by using official PETKIT waste bag refill rings.
If the camera still fails: replacement options
If your gold pogo pins are completely clean and the rotating track is clear of clay dust but the PETKIT app continues to display "Camera missing" or "AI Camera offline," the internal wiring or the pogo pin springs have suffered hardware failure. Replacing the modular AI Camera assembly will instantly restore power, communication, and cat facial recognition health tracking.

Auto-packing and bag sealing: advanced troubleshooting
The PETKIT Purobot Ultra features an advanced automatic waste bag packing and thermal sealing system. Since these components interact with the waste drawer, fine litter dust can occasionally interfere with their operation.
"Refill ring missing" or automatic bag sealing failure
The Purobot Ultra uses a proprietary waste bag refill ring embedded with an RFID tag. If the app displays a "Refill missing" error even though a ring is physically installed, the RFID reader on the packing module base is likely blocked by clay dust or moisture.
To resolve this: remove the refill ring, use a dry microfiber cloth to wipe down the plastic packing deck surface, and reinsert the ring.
If the bag fails to seal during a packing cycle, verify that all packing module parts are seated properly. Turn off the unit, inspect the refill ring, the refill ring cover, and the waste trunk to ensure they are all flush and locked in place. Power the unit back on.
To test the sealing mechanism manually, stand next to the litter box and use the physical OLED control panel: press the menu button to navigate to "Packing", press OK to confirm, and then double-press OK when prompted on the screen to start the cycle. Do not leave the device unattended during a manual packing test.
OLED screen displays error symbols (Trash or Bag icons)
The physical OLED display screen on the Purobot Ultra will flash specific icons to alert you of packing-related faults:
- Flashing Trash Icon: The waste tray bag is full. If you have recently cleared the tray and the icon continues to flash, the optical infrared sensor window inside the drawer cavity is blocked by dust. Slide the drawer out, locate the sensor window on the upper frame, and wipe it clean with a dry microfiber cloth.
- Flashing Bag Icon: The waste bag film has run out. Remove the empty cartridge, install a new refill ring, and pull the fresh liner film through the sealer slot.

Frequently asked questions
Why does my Purobot Ultra say "Camera missing"?
The "Camera missing" error is triggered by a poor electrical connection at the pogo pin contact interface between the removable camera module and the main litter box frame. Fine clay litter dust, hair, or room humidity settles on these gold contacts, insulating the signals. Wiping the contacts on both the camera and the chassis port with a dry cotton swab restores the connection.
Why is the Purobot Ultra AI camera stuck and not rotating?
If the camera is physically stuck and fails to rotate, clay litter granules or fine dust have wedged inside the camera's rotating base track gears. The motor stalls to protect itself from overcurrent damage. Unplug the litter box, remove the camera module, and use a soft brush or compressed air to clear all debris from the track.
What do the indicator lights on the Purobot Ultra camera mean?
- Solid green: The camera module is powered on, successfully connected to the mainboard, and actively tracking. - Off / dim: The camera is either powered off in the app settings, or it is not receiving electric current due to dirty pogo pin contacts.

Still not fixed? Here’s what to do next.
Some faults are genuinely hardware, and no amount of cleaning or resetting will clear them. If you’ve worked through everything above and it’s still doing it, stop here rather than taking the unit further apart.
- Go to PETKIT directly. If the unit is still under warranty, let them replace the part rather than paying for it yourself — contact PETKIT support.
- Tell us what didn’t work. We rewrite bulletins when readers show us a case they don’t cover — compliance@pet-infrastructure.com. Tell us the model, what the lights are doing, and which steps you already tried.
- Ask other owners. Search Reddit for your model name plus the symptom (for example “PETKIT Purobot Ultra not cycling”). Someone has almost certainly hit the same fault, and owner threads often surface fixes before the manufacturer documents them.
When to stop and call the manufacturer: if the fix needs the base opened, the motor or control board touched, or any tool beyond a screwdriver — stop. On a unit in this price range, opening it yourself usually voids the warranty, and a warranty repair costs nothing.
