No. The auto waste packing process requires users to be present next to the device. You can start the auto-packing by pressing the button on the OLED screen. The entire process includes auto-packing, auto-sealing, removal of the trash bag, and auto-bagging. Once a sealed trash bag is ready, the user need to remove it. Auto-bagging will not initiate until the user take out the trash bag and double click the button on screen for auto-bagging.

No, the auto waste packing system requires PETKIT’s exclusive refill rings. These refill rings are designed for a seamless fit, ensuring smooth auto-packing. Using generic trash bags with the refill ring may lead to malfunctions.

The refill ring package contains 3 pieces. One piece of refill ring can pack approximately 10 times, and the waste bin can hold one cat’s waste for up to 20 days. The data was tested by PETKIT Lab based on the toileting frequency of a single adult cat. The replacement frequency depends on the number of cats in your household and their litter box usage patterns.

Based on PETKIT’s lab results, the waste bin supports up to 20 days of free-scooping for one cat. However, if you live in hot and humid conditions, we recommend packing the waste more frequently according to your preference.

The large space inside the trunk of PUROBOT ULTRA is designed to accommodate the auto-packing system. This feature requires ample room to operate effectively. The packing module is engineered to lift up during operation, ensuring proper and successful packing of waste.

We recommend a minimum weight of 1.5 kg (3.3 lbs) and a maximum weight of 10 kg (22 lbs) to use PUROBOT ULTRA.

We don’t recommend using PUROBOT ULTRA for kittens under 1.5 kg (3.3 lbs) or younger than 6 months, as they might not be able to trigger the weight sensors. For small kittens above 1.5 kg (3.3 lbs), we suggest activating the Kitten Protection Mode. Auto-cleaning and periodic cleaning will be disabled in this mode to ensure your kittens’ safety.

Yes. PETKIT always put cat’s safety for top priority. PUROBOT ULTRA features X-axis rotation to keep the entrance open at all times and is equipped with 20 high-precision safety sensors, including advanced proximity and weight sensors. The litter box immediately stop rotating when a cat enters the cylinder, and the weight sensors ensure it remains stationary while your cat is inside until they exit.

For accurate weight measurements, the PUROBOT ULTRA should be placed on a hard, level surface. Maintain a distance of at least 5 cm (1.97 in) from walls and ensure that no objects obstruct the entrance.

PUROBOT ULTRA includes two sifters, compatible with most clumping cat litter. However, we don’t recommend use cat litter longer than 12 mm or wider than 3 mm.

PUROBOT ULTRA's new cat litter pad features a larger inner litter bed (1272 cm²) to improve clumping performance during cylinder spinning. To prevent feces on the walls, we recommend use fast and tight clumping cat litter rather than slow-clumping varieties. If your cats don't bury their poop or have watery poops, streaking may occur when the cylinder spins. Please ensure that you use the recommended amount of litter to optimize clumping and reduce streaking.

Position the PUROBOT ULTRA where the previous litter box was located, using the same type of litter. Mix a scoop of the old litter with the new to maintain a familiar scent. Allow waste to accumulate gradually in the old box to ease the transition. To help your cat get accustomed to PUROBOT ULTRA, gently guide them inside when needed. Be patient with sensitive cats that may take longer to adapt to the automatic litter box.

The PUROBOT ULTRA firmware supports OTA (Over-the-Air) updates remotely, allowing for progressive releases and enhancements of new features. You will need to manually update your firmware through the PETKIT App.
