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.

And if you're cutting steel with a lubricant
(which Bosch saws will do--the old ones even had
a powered lubricant dispenser accessory
available that was driven by the saw) do you
really want to be sucking the lubricant and
chips into the mechanism?

Into the mechanism? I don't think you want to blow it around the
room, either.

Of course you can always go green, but even
green doesn't suck with the saw's mechanism,
they just provide a dust port to which a
(preferably green) vacuum can be attached.

Sure. I wouldn't want to steal power from the saw for the vacuum, nor
would I want to control but the saw and the vacuum.
