Just bought this vacuum. Owned a Craftsman for 20 years. Gripes about the Ridgid WD1950. Whoever designed this obviously doesn't vacuum. All wheels should swivel. Ever do any vacuuming you will know that the vacuum invariably gets pulled along by the hose. Try that with the WD1950. Not only will the WD1950 vac veer off to the side, it will turn right around and guess what. All the sawdust that I'm trying to vacuum is sitting at the same height as the exhaust port on the WD1950. Huh. Point the exhaust straight up not out the back. This is a professional vacuum. These are not well thought out design touches.
