many uses.I started using the Festool version, prob. first one on the market.many different applications, walls, floors, etc.the sealing on this one is not quite on par with the Festool, but it works if the surface is flat enoughthe suction is pretty good, gets rid of the bulk of the dust.on textured stucco, u gotta use two hands.this is about $20 less than the Festool version, so a good value for sure.See full review
