IIRC, my 1590 does have a blower... it's good enough. It's the switch
with two positions.

Sucking is better than blowing.


Not always. (Do you like to argue?) Try this experiment (Bill Pentz
came up with it): Take a ping pong ball and two straws. One person can
only blow through the straw and the other can only suck. Try to get the
ball to go out of a circle or into an area. The person blowing will win
every game.

If you need to see a line, a blower can be more efficient than trying to
suck the dust away.
