Widerider, you are referring to the SC679J, yes?
I haven’t had one but I’ve heard nothing but good things about them. The SC679J is tried and true for sure. That said, you might want to consider the SC684 over the 679. For only around $50 more, you get
-a cord which is 20ft longer
-large rear wheels which allow the vacuum to be wheeled while it is upright
-large bumper
-deeper fan blades for more airflow
-steel Vibragroomer II brush roll with replaceable brush strips versus the wooden/plasic Distribulator
-higher amperage motor (7 amp versus 5 amp)
Seems like a pretty good upgrade.
