I do AV install mostly and cut a lot of single gang holes in sheetrock as well as speaker cutouts and long tracked cuts in sheetrock to run wires throughout homes also drill out tons of wood studs. This vaccum is all I need on the job site as long as I vaccum while drilling or cutting this thing is perfect. It's feature strong suction and is very ergonomic lightweight and can easily be used simultaneous while drilling or cutting by one person which is exactly what I needed. I was skeptical before buying but after putting to the test every day I couldn't be happier. As long as the unit is cleaned or regularly it powers through wood dust shavings and sheetrock dust all day. I like to Carey minimal tools and weight to work especially working throughout Manhattan and this vaccum is tiny lightweight and gets the job done. I highly recommend it to professionals in the field.
