I have only recently bought my Karcher & Im over the moon with it, it takes all the hard work out of cleaning windows shower cubicles & such like so yes I would say it will clean your quartz work tops, it certainly is a good buy, 😀
My daughter has a granite work top so I'll try it out later this week and get back to you

This vacuum will suck all water left behind from the cleaning process & should leave a streak free finish if used correctly. There is no polish function on this product that I am aware of.
Yes, I believe it will safely clean the quartz worktops without damage or scratches
