sander track reasonably well -lrb- not great - yet far better than the old craftsman that be throw out -rrb- , be able to handle rough grits easily -lrb- unlike the AEG I give up on -rrb- . do what I ask it to do -lrb- rough sand -rrb- BUT will clog quickly -lrb- something that seem to be prevalent in other review I have read -rrb- . the primary reason for write this review be to advise that it be easy to clean the clog with a air compressor gun -lrb- not like another reviewer who disassemble he machine to remove the clog with small screwdriver -rrb- . as another reviewer note the dust bag be less than adequate -lrb- I run it directly into the shop-vac - which leave a clean surface and little dust in the air -rrb- . for the price a decent machine that still could use some improvement in the problem area , but not one of Bosch 's best product .
