Summary: Was using another small portable wet/dry vacuum for general HVAC and maintenance. It worked OK, but I got tired of having to either lug around the original box or try to carry the vacuum, hose and a few attachments separately. This Ridgid has everything stored nicely in a toolbox shape for easy hauling. It sucks up metal scraps and sheetrock debris with no problem and is much quieter than a typical "Shop-Vac". Overall very pleased with it.
Summary: This thing is a real treat. Its box-shape makes it much easier to pack in your truck or closet, the hose is very flexible unlike the stiff plastic hoses of many others, and best of all, the hose and various attachments stow inside the unit meaning you don't have to wonder if you left the brush tool at home. Using the Ridgid vacuum bags, I've been able to suck up pounds of drywall-sanding dust with no problem. Personally I don't miss having wheels on it.
