Cons: This machine is so heavy nobody wants to vacuum. The mechanism that holds it upright broke right away. The safety piece that lets it run broke. The none breakable hose cracked; as well as some attachments. The replacement parts are very expensive. Only cleaned as well as demo in the beginning. A pain to switch out attachments. I worry about it wrecking my hardwood floors due to its weight. Pros: We have done an enormous amount of remodeling over the 8 years we have owned this machine and the sander attachment is our favorite part. We have flatten stucco walls with it. Most of the dust is vacuumed up as you sand. The motor will last a lifetime. Metal parts are a plus. Belts are inexpensive.
