Cleanup is very minimal. About what you'd have from eating a dozen soda crackers. That's the beauty of the siphon blaster.

The construction of a siphon blaster is such that it projects the blast media and also sucks it and the glass shards up at the same time.

You should probably get the video that Norm Dobbins has showing the actual use of a siphon blaster to see just what happens.

Be advised though that the siphon blaster will not allow deep penetration or stage blasting of the glass. However, since most on site work is with tempered glass you won't be trying for depth.
