  • Page 21: Cleaning Information

    RX-20 5 - Cleaning Information CLEANINg PATTERNS for regular carpet cleaning use an overlapping arc pattern three times over the same area (two passes with solution and one pass for drying).

  • Page 22: Special Information

    RX-20 SPECIAL INfORMATION When you clean some plush carpets, you may notice a “pilling” effect. (pilling occurs when fluffy particles appear on carpet surfaces; it is caused by fibers that loosen because of a weak twist or snags.) With an RX-20, loose yarns form balls and are kicked aside as the cleaning heads revolve. This is normal when aggressive cleaning or even normal vacuuming takes place, as evidenced by a number of dead, loose yarns in the vacuum cleaner bag.

  • Page 23: Machine Maintenance

Keep in mind that your RX-20 will be in full view of your customer. An RX-20 that is dirty and unkempt in appearance can cause your business or professional image to suffer.
