Ecovacs T9 AIVI Station CH1918 – Plus.Parts® Replacement Dust Bags

The Ecovacs T9 AIVI Station CH1918 is the auto-empty docking station for the Ecovacs Deebot T9 AIVI robot vacuum, identified by its CH1918 product code. The station uses a high-speed suction motor to generate a burst that clears the robot’s compact onboard bin after each cleaning session, depositing accumulated debris into a sealed bag housed within the dock body. This shifts the manual interaction frequency from daily or every-other-day bin emptying to periodic bag replacements every few weeks.

The dock bag’s available capacity determines the effectiveness of each transfer cycle: as the bag fills toward its limit, the suction burst has progressively less room to deposit debris from the robot’s bin. A bag that reaches full capacity can leave residual debris in the robot’s bin after docking, gradually affecting cleaning coverage over subsequent sessions. Replacing the bag before that threshold maintains complete, consistent bin clearing on every docking event.

This set contains three Plus.Parts® dust bags for the Ecovacs T9 AIVI Station CH1918. Each bag is sized for the station’s compartment, seals at removal to contain the collected debris and fine-particle matter, and uses filtration material that preserves airflow through the bag wall as debris accumulates across its service life.

The filtration media maintains fine-particle capture across the full fill cycle, from early use through to the recommended replacement point. Questions about compatibility with the CH1918 station? The team responds personally and directly.
