Questions about this item

How does the 110G weight affect the robot's mopping performance?

The 110G tank adds minimal mass so the Roborock S7, T7S, T7S PLUS or G10 maintains normal navigation and water flow during mopping.

Which connection does the HCDM2065 water box use to attach to the robot?

It slots directly into the dedicated water-tank compartment on the Roborock S7, T7S, T7S PLUS and G10 models.

Will the replacement tank fit the same mounting points as the original on my Roborock S7?

Yes, the box is moulded to the original dimensions and clips into the existing rails without modification.
