Can one use a turbo blaster to remove possible dust spot on sensor of a mirrorless camera like one can on a DSLR?

Yes

Yes, the sensor is essentially the same in a mirrorless camera, just no mirror in the way.

If it is the rubber bulb, yes, but not the one on E-Bay that hooks to an air compressor!!! wow that would be a blast. When looking for sensor dirt use an open f stop so only sensor dirt would be in sharp focus.

Actually you are not cleaning the sensor there is most outward the IR hot mirror and below that the Anti-aliasing filter.

Actually you want a narrow f-stop so you can see the dust, f/22 is usually good. Pick a lens in the 70-100mm range. Pick a white or light target, like a wall, piece of paper or the sky. Defocus, if you’re shooting a wall or piece of paper focus at infinity, if it’s the sky the closest focusing distance. Shoot at your lowest native ISO.

Exactly. And doubters can prove it for themselves. Just compare the test shots of f/22 and f/2.0 at equal EVs. Typically, much more distinct dust seen at f/22 goes fuzzy or even disappears at f/2.0.

When youre chasing down any particular particule, dont forget that north is south and east is west concerning the monitor image vs the sensor.

What?????? I am I hearing correctly "sensor in mirrorless camera essentially the same as in DSLR" Surely not !!!!! They MUST be better or why bother changing

User ID

Well OK. If it makes you feel better, they actually ARE better ... simply becuz they need to be better. But acoarst theres no physical or electrical problem preventing putting those better sensors in SLRs, as the mirror is an autonomous entity that has no part in recording images. Rather the opposite ... its usually in the way !

Why do I love mirrorless? Let me count the ways:

1. Smaller body by removing the space needed for that yesteryear flapping mirror.
2. IBIS that turns every lens into a stabilized lens, even the golden oldies of the manual focus, pre-electronic ages.
3. EVF with shimmering highlights of the plane of focus.
4. Histogram available for display in electronic view finder (EVF).
5. Detailed 10x zoom in EVF.
6. Silent (not a single noise) shutter.
7. Extreme frames per second, 20+.
8. Image playback in EVF for review when LCD impossible to see in bright light.
9. Image playback at 10x zoom in EVF.
10. Sharper mirrorless lens designs.
11. More ultra fast lenses as sharp wide open as any stepped down DSLR lens ever.
12. One digital platform supporting portfolio of legacy DSLR lenses, legacy SLR lenses and modern mirrorless lenses.
13. Autofocus beyond f/8 for extended configurations.
14. Platform for any / all ongoing technology advancements in digital photography.
15. EVF that displays the results of the image before shooting.
16. EVF that allows for ad hoc updates like boosting the ISO for a brighter focus view, then restore ISO and shoot, without even lowering the camera from a shooting position.
17. Entire frame available for selective AF position.

And yet, none of these technology marvels changes that a digital sensor sits inside a mirrorless camera, to be cleaned in the same manner as the DSLR sensor that requires the mirror to be locked-up. Mirrorless doesn't have a mirror to be locked-up.

Essentially the same as far as materials and basic function. The stacked BSI sensors in my OM-1 and Z9 are a far cry from what’s in your DSLR. Cleaning them is the same.

I agree with you!
