The Ecovacs T30 Omni Station CH2311 is the auto-empty dock unit for the T30 Omni series, responsible for drawing debris from the robot after each cleaning session and sealing it in a bag stored below the dock housing. At a single daily cleaning cycle, the bag changes roughly every two to four weeks; households running the robot on multiple sessions per day reach that threshold faster. A twelve-bag supply keeps the station stocked through an extended period without requiring a re-order mid-run.
This twelve-bag dust bag bulk pack from Plus.Parts® fits the bag bay of the T30 Omni Station CH2311 and the full T30 Omni and Yeedi M12 lineup: DDX11, DDX14-12EDR, DDX14, Deebot T30 Omni, Deebot T30 PRO Omni, T30 Omni Station CH2311, T30 PRO Omni Station CH2311A, Yeedi M12 Pro+, and Yeedi M12 Ultra Plus. Each bag slots into the bay and seals before the transfer cycle runs.
Fit and seal are checked against the CH2311 station bay format before dispatch. Arrival issues are handled by our team on direct request, without delay.
