Trash Bag Refill Ring

Refill Ring Exclusive to PUROBOT ULTRA for Seamlessly Wrapping Up Cat Waste

The refill ring is equipped with a seamless bag roll and guarantees a smooth automatic wrapping process. Even an overflowing waste bin will not disrupt the process—the waste bags automatically expand to ensure a perfect seal every time.

Hundreds of Tests for Guaranteed Durability

Our waste bags are made from high-quality polyethylene (PE) selected from a wide range of materials and tested hundreds of times in the lab. They offer the ideal balance of durability and sealing efficiency.

Long-Lasting Waste Management

Integrated, sleek, and built to last. Each exclusive PETKIT refill ring can be refilled approximately 10 times*, and the waste bin can hold up to 20 days' worth of cat waste.

*These figures were tested by the PETKIT laboratory based on the frequency of bowel movements of a single adult cat. Actual frequency may vary depending on cat litter box usage habits and your cat's specific waste disposal needs.

Visible Warning Mark on the Waste Bag

If you see a ⚠ symbol on the waste bag, it is time to replace the refill ring.

Smart NFC Detection

With NFC detection, you can receive a timely reminder via the app when the waste bag is running low.

Effortless Installation and Replacement

The refill ring features an integrated, sleek design that makes installation and replacement a breeze. Say goodbye to the hassle of manually filling your waste bin.
