When exploring the Ecovacs T30S vs. T30S Combo lineup, it's crucial to know that the series features two distinct dust bags: one for the standard T30S series and another specifically designed for the T30S Combo series. While they look incredibly similar, choosing the wrong bag can lead to severe contamination inside your base station.
Similarities: Capacity and Material
Despite having different model numbers, these two bags share identical basic specifications and materials:
Capacity and Dimensions: Both hold 3 liters and share the exact same overall exterior dimensions.
Filtration and Odor Control: Both are constructed from multi-layer non-woven and melt-blown fabric, featuring an integrated activated carbon layer to neutralize odors.


Differences: Adapter Plate and Sealing Ring Geometry
The critical difference lies in the design of the cardboard plate. The base station's suction inlet has a fixed aperture, and the dust bag's adapter must seal tightly against it.
T30S Dust Bag
Compatible Stations: T30S auto-empty station, T30S PRO/AI, X2 Omni, and X5 Pro Omni. But it can also be used for T30S Combo.
Visual Features: Features a smaller rectangular cardboard plate with an inset, smaller round collar seal.
T30S Combo Dust Bag
Compatible Stations: Designed for the larger Combo station, fitting the T30S Combo and X2 Combo. But it can not be used for T30S.
Visual Features: Features a larger, flush-mounted rectangular cardboard plate with a prominent, larger oval black rubber seal.
