ToolManDan
By ToolManDan
Tired of cheap/loud shop-vacs, narrowed my choices to the Fein Turbo III, Festool and this Bosch 3931A. After reading all reviews and specs, decided on the Bosch. This Vac is not very popular on Forums and I don't know why. The Bosch is slightly more powerful than the Fein Turbo III and also very quiet. I added the accessory basket and bought several bags. I use the 1-1/2 Mr. Nozzle Hoses, and their 1-1/2 nozzles (complete line available from Woodworker's Supply) with all my vacs so the 2-1/4" tank fitting fit the Bosch with no problems. If I could find anything negative about it is it's weight, but I use it only in my shop, so that's not a problem for me. Some will complain about the cost of the unit and its accessories (bags, etc). I don't mind the cost since I'm a hobbyist and it's worth having a vacuum that matches the quality of all my other shop tools. Determine your requirements for a vac and if they're like mine, you won't be dissatisfied with the Bosch 3931A.

Self Cleaning Vacuum
By R. R. Walter
We started using the Bosch 3913A Vacuum on a large concrete resurfacing project that is on the beach here in Southern California. In the past we have had problems with our vacuums clogging up very fast because of the dust mixed with the continual moisture. The self cleaning on this vacuum works great. Our second use of this vacuum was the the removal of paint in the same environment. It worked great. The automatic self cleaning feature is a must. We found nothing negative about the vacuum.

Great tool!
By Kenneth C. Reed
I looked pretty hard for a good shop vacuum (Festool, Fein, Porter-Cable and others)and I'm pleased with this unit. It is quiet enough to carry on a normal conversation with someone when it is running, which means I'm much more prone to use it than my old screamer vac. The Power Broker function works as advertises, the barrel has plenty of capacity for my needs, it accepts hoses from other vacuums, the hose it comes with is very good quality and it fits my Festool sanders, and the self-cleaning filters keep the unit functioning at peak performance. The auto on/off feature is great, but a lot of higher end vacs have this feature too. No, it doesn't come with attachments, but if you have another vacuum that your are replacing I would think you could use those hoses and attachments like I did. Lots of suction power, and it moves a lot of air. No exhaust blower, but I imagine that's how they got it so quiet. Highly recommended!
