The TrimPro Rotor Workstation is the table/stand on which you sit your TrimPro Rotor. This stand makes your trimming sessions more efficient by having all the leaves collect in a bag below the machine rather than building up in its base. It also allows a certain level of airflow through the machine slightly increasing its efficiency. Most customers wouldn't use their Rotor without it. When ordering the Workstation/Rotor Med a stand is included with the purchase of every Rotor Med, you get one box for the machine and one for the stand. 800830 is special order only.
