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. These loose
yarns, in most cases, are short staple yarns or filler yarns used to give the carpet a denser
appearance.
Because your RX-20 weighs approximately 70 lbs and rests on five 4” cleaning heads,
the yarns are not sucked up into the vacuum heads as they are with a vacuum cleaner or
old-style cleaning wand.
On older, rubber backed, glued down carpets that may be delaminating with age,
the RX-20 may cause further delamination. When in doubt, dO NOT use your
RX-20 on such carpets.
CLEANINg HINTS
Most cleaners customarily clean their way out of 1.
an area or room. With the RX-20, you can clean
into an area or room, as shown in the figure 5-1,
so that the hoses are dragged behind you during
the cleaning process rather than kicked out of the
way as you back out of an area. The “cleaning
into” method works especially well in hallways or
confined areas.
The RX-20 is a very aggressive carpet cleaning 2.
power head and will leave the carpet with a
freshly cleaned appearance. The carpet should be
brushed or groomed after the cleaning process to
remove any swirl marks left behind.
The RX-20 has been very successful in restoring badly matted traffic lanes in front
3.
of doorways and sofas. Even pivot areas can be brought back to life again, in most
cases. “Cornrowing” in hallways can also be eliminated with minimal effort.
