Now weeks later there's dust on the sensor, so I'll be having it cleaned again, I'm reluctant to do it myself in case it affects the warranty.
It doesn't, any more than pumping your own gas in your car does. It's a regular part of camera maintenance, so you might as well get used to it. As mentioned, the place to start (after trying the automatic dust removal system) is with a blower.

Incidentally, my other cameras, in all the years I've had them, have never had a problem, both Olympus. . .
Luck of the draw. All DSLR's get dust from time to time, that's just the nature of them. The various automatic dust removal systems do what they can, but dust happens.

I used the K20D for 3 years and only had to clean the sensor maybe 3-4 times. I have always used a Giottos Rocketblower. I've never had to use a wet cleaning method.

I had the dust removal set to run everytime I turned on the camera. I used the camera at rodeos (plenty dusty) where I even changed lenses. To me, the dust removal on the K20D must work pretty well. It's certainly not prone to dust problems, from my experience. In fact, it was a great camera and I somewhat reluctantly sold mine to buy the K5.

Shot in some horrific enviroments with K20 for almost 2 years now and never
really had a problem.Did have to literally 'debug mirror' when I switched lens during a
caddis fly hatch.Know those rocketblowers work great,never bothered to pick one
up because of 30 something year old de-soldering bulb that works fine for that purpose.
Have wrapped several rubber bands around mating point of lens/body flanges
as extra 'insurance so nothing might migrate into mirror box.
