Product Description
From the Manufacturer
Bosch power tools and accessories introduced its new power broker system and other key enhancements to the award-winning Bosch airsweep 13-Gallon wet/dry vacuum. Now, users can utilize the Bosch power broker system to avoid blown circuits and optimize overall performance by allocating the available power between the vacuum and a connected power tool, as necessary. The newly designated 3931A also encompasses the celebrated features of the previous generation 3931, including the pulse-clean electro-magnetic automatic filter cleaning system. Whether sanding or routing in the shop or concrete surface grinding or tuck pointing high on a scaffold, a power tool activated vacuum that constantly trips circuit breakers wastes time and money. For this reason, Bosch developed the new power broker system, which allows users to utilize the entire amount of available power 15-Amps on a 15-Amp circuit, 20-Amps on a 20-Amp circuit and allocate it between the vacuum and a connected power tool. Additional 3931A enhancements include new rear wheels and metal front casters with rubber tires for easy transport across all types of surfaces. And a new special stiff rubber swivel nozzle ensures a quick and snug connection to vacuum cleaner attachments, Bosch power tool dust ports and Bosch adapters for other power tools. The innovative Bosch 3931A airsweep vacuum also includes the same celebrated features of the previous generation unit. Superior suction power is derived, in part, from the large surface areas of its unique U-shape twin filters. Positioned out of the direct flow of incoming debris and above the reach of the dust or liquid that has already been vacuumed, the standard filters will capture 99.93-Percent of all particles 3.0 microns and larger in diameter. Furthermore, the 3931A has the quickest and easiest filter change system on the market, allowing users to simply open the lid and drop replacements in.

ToolManDan,
This review is from: Bosch 3931A Airsweep 120-Volt 13-Gallon Wet/Dry Vacuum Cleaner with Power Broker (Tools & Home Improvement)
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,

This review is from: Bosch 3931A Airsweep 120-Volt 13-Gallon Wet/Dry Vacuum Cleaner with Power Broker (Tools & Home Improvement)
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!,

Amazon Verified Purchase(What's this?)
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!
