VersaPro Rotary MultiTasker With 17" Apron Clean Every Floor Surface Possible *Optional accessories pictured are not included with machine Having this one floor machine allows the cleaning professional to have the widest array of options and only have to invest in one machine. With other rotary floor machines, if you wanted to have a larger or smaller cleaning area ( 13"-21"), you would have to invest in five different machines. With the Versa Pro, you buy one, you get five, so to speak. All you have to do to change the size of the cleaning machine, is to buy the interchangeable aprons. You can use the 13" apron to get into those tight spaces and cubicles. You can use the 21" apron for maximum cleaning coverage in wide open commercial areas.
