Sensor cleaning (prospective owner)

Sorry if this is covered in a manual I don’t yet have (this is pre-sales), but do the Z-cams typically have a sealed sensor without AA filter/dust shaker? Can I clean the sensor with Dust-off and not have to worry about dust getting lodged between the sensor and AA filter? Or lens fluid wicking around to the backside of the filter?

In particular I’m interested in how this applies to the -S6.

Thank you,
