WAP Drywall Vac 
This is the ONLY Vac for me! It is incredibly quiet and the filter bag captures ALL of the drywall or dirt you can put through it.
Alto Drywall Vacuum
I purchased the Alto Drywall Vacuum with Auto Start from Amazon three months ago as a replacement for my old Shop-Vac brand machine when I couldn't stand the noise of the old vacuum any longer. The Alto machine is primarily for use in my small garage shop, but it has proved to be far more versatile than I expected.The Alto is very well made, quiet, and powerful with a first rate fit and finish. The only accessories that come with it are a hose, two metal extension tubes and a solidly made metal floor tool with a brush insert, but the metal end of the vacuum hose is a perfect fit with the attachments made for the German Miele vacuum cleaner.
The Alto is too large and heavy for every day household use, but the combination of the Alto Vacuum and the Miele attachments results in an excellent quite shop vacuum that can be used as a very versatile, supper heavy-duty, domestic vacuum to clean the cars, the house, and other finished interior spaces when heavy duty vacuuming is needed.
This machine is much more expensive than the other shop vacuums that are available. However, it is a much better made and far quieter machine than any of the other shop vacuums, and it is far more vacuum cleaner for the money than the Miele. So far I am very pleased with the Alto machine and have no regrets about spending the extra money to get it rather than a less expensive machine.
