Sucks dust
There arent many products in this category available. This was purchased for fire rehab and worked well at an overall cost less than other alternatives.

BEST ANSWER: Bosch makes no statement that it is compatible with other brands of grinders. They share only that it is compatible to their AG series and 1800 series 4-½" and 5" Bosch small angle grinders and that it is Bosch AIRSWEEP™ vacuum compatible - plug and play without using adapters.
