I want to buy a pressure waher to clean my crazy paved drive, and am worried about dislodging the grouting. Are there any washers with attachments that I can buy to stop this? |P

If the grouting is in such poor condition that a pressure washer is likely to blow it out then it badly needs redoing anyway. However, all pressure washers come with an attachment which will guarantee this doesn't happen. It's called an off switch.
An attachment called a 'T Racer' or similar (many others are available)
But as Dave says, if its that bad it needs sorting.
I am often surprised by the gadgets which *are* available, but HTF could they design something that could distinguish between slab and grout and go easier on the grout?

So low pressure water into a device that boosts the pressure, then into something that reduces the pressure back to where it started from so as not to damage anything? Interesting.
You can get patio washer add ons that convert the water jet to a rotary jet/brush action. These are less likely to cause damage.
See here:
Presumably some form of optical/proximity sensor on one of those scrubbing-bruush attachments could divert the jet of water when it passes over the grout.

Looks good. According to Kaercher it can be used around the home as well - or at least they say that it stops irritating dirt being spread around the home. Decreased "motor ware" as well
Just like electricity distribution......

Erm....
Well.....
Power station generators having an output of a few 10s of kV I believe.
Step it up to deliver cross country in the 100s of kV
Step it down to low voltage for the point of use partly for safety reasons.
Nah! Simply that the pressure jet(s) are angled at about 30 degrees in order to turn the spray bar. Because the jets are constantly at this angle they wash across the grout rather than directly at it. They work well on block paving because of this, washing out much less sand than an ordinary pressure washer lance.

Yeah, not quite the same though as there is a reason behind that.
