High Tech Service Equipment

Okay, I’m looking for some input from readers.

What are the coolest high tech service equipment and tools that you’ve seen?

I’m not talking James Bond stuff, I’m talking every day equipment that service companies and professionals use to make their jobs easier.

For example, truck mounted vacuum systems. These things could suck a camel through the eye of a needle it seems.

What else have you guys seen around town, or that you personally use that is cool?

Wanted to give some credit to the great guys over at Willard Power Vac Duct Cleaning. They do fantastic work.
