PowerHead
®
DO NOT operate your PowerHead over loose or unraveled carpet seams. The
cleaning head may catch and cause further damage.
DO NOT operate your PowerHead on concrete floors. Sharp edges will develop
on the extraction heads which will damage carpet fibers.
DO NOT clean over the edge of a loose carpet. Instead, clean only up to the
edge. Damage may occur if the extraction heads catch the loose carpet.
SPECIAL INFORMATION
During the cleaning of 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 weak twist or snags.)
With a PowerHead, 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 PowerHead 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.
The PowerHead may cause further damage to older, rubber-backed, glued down
carpets that may be delaminating with age. When in doubt, DO NOT use your
PowerHead.
