HAVE, GET + object + past participle

Have/get + object + past participle means "cause something to be done". We use this structure when we arrange for a professional to do something for us. Get is more informal:

Did you have your computer fixed?
I need to get my suit cleaned.

This structure can also mean "experience something unpleasant":
