Powr flite 6 quart backpack hepa filtration quiet, versatile. I have an electric power nozzle that powr flite sells. I much prefer paper bags as they are quick and easy to change with no dust on me or in me. Ironside , been there done that. an all metal chassis and fan, but a wooden brush roll? and when a small pebble got lodged in the brush roll and stopped it from turning, just another belt burner, you do have plenty of spare belts, don't you? Dirt cups are easy to empty but you still have to empty the cloth bag or you lose suction.
