Powershot SD790 IS (Ixus 90) - Potential dust on sensor - help please!


First post here, hello! I've been trying to troubleshoot an issue I have with my Ixus 90 - it looks to be dust on the sensor. It manifests as a feint black blob on at the top of the frame. It's most visible at f/4.9, not so visible at f/2.8, and not noticeable at f/8. From the research I've done, it looks like it could be dust on the sensor?

I've uploaded some photos which are a good examples. Any help/recommendations to resolve this would be appreciated.

The camera is pretty old now, but I do love it. Given that I'd like to stick with Canon, could anyone recommend a replacement for this little beauty. The Ixus 255 looks pretty good.

Thanks in advance and hello again!


Edit: here is a photoset with the examples:
