The carpet you see in this photo is obviously much dirtier than the average job. The reason for this is to demonstrate the dramatic difference between the cleaning ability of a wand vs. a Rotovac Powerwand.
Using the same portable extractor and the same chemical, we cleaned one portion of the carpet with a wand for two minutes and then right next to it with the Rotovac Powerwand for two minutes.
When cleaning with the wand,
the operator applied all the effort he could and made approximately 120 cleaning passes. How long he could sustain that cleaning pace would depend on his strength, stamina, and work ethic.
In just two minutes the Rotovac produced 3,000 multi-directional cleaning passes. Here you can see how the cleaning results of the Rotovac are dramatically superior to the wand.
