Manual scrub wand is a good carpet cleaning tool for cleaning lightly soiled carpet. When cleaning more heavily soiled carpet, the wand becomes a ‘beast of burden.’ Cleaning results depend upon the strength, stamina, and technique of the person working the wand. Cleaning heavily soiled carpets with a scrub wand is ‘hard labor.’ The repetitive motion of scrubbing back and forth is extremely strenuous and fatiguing. An individual can not scrub long enough to effectively clean your carpets. First and foremost the Rotovac is an electric power scrubbing tool. Comparing the Rotovac to a wand is like comparing a skill saw to a hand saw. We have converted a back and forth manual task to a much easier and more efficient rotary mechanized operation. Which makes more cleaning passes per minute than is possible with a manual scrub wand. In addition, the cleaning passes are from all directions rather than just back and forth. This is what produces better carpet cleaning results for your home or place of business.
