Most home workshops have a wet dry shop vac. This video shows you some of the latest features in wet dry vacuum technology. There is the traditional wet dry shop-vac and the upscale model. They both can pick up water, pick up saw dust or to vacuum up the things you don't want inside your regular vacuum.
Shop vacs can be used to clean up messes, soak up water, clean out the car and for rough construction projects if you are creating a lot of saw dust. If you are the one guy in the neighborhood that has to have the fanciest model, check this one out.
Traditional shopvacs have a simple on/off switch. This upscale model a four position switch which include a filter self cleaning switch and a switched outlet to hook up to another piece of equipment. This one powers a receptacle that is hooked to another tool that might be the source of the dust. This ensures that both the power tool and the vac are turned on at the same time.
Ever pull the shop vac by the hose and end up with only the hose? This model has a twist lock suction hose to lock the hose in place. You can pull it around and it will not come disconnected.
This particular shop-vac comes with all the attachments - crevice tool, different wands, and even a squeegee tool. Everything you need to clean up that mess in style.
