It's run on air instead of a little electric pump.

There is a tube connected to the spare tire that is filled to about 45 psi, goes to the water tank, then goes to the button, then to the windshield.

Your expected to release the extra air out of the good spare when you have a flat, but then you won't have a windshield washer now that the bad spare is flat.

This is true, but nothing is stopping a Bug owner from installing an electric pump. You can get one for about $10.
