PRECAUTIONARY
MEASURES
Use the spray
extraction method only
when the textile wall
or floor covering and
the wall or floor cannot
be damaged.
– Take care on wood or
floors sensitive to
water.
– Take care with carpets
which have been laid
using water-soluble
glue.
– Take care on carpets
with a backing fabric
sensitive to water (e.g.
jute).
– Take care on natural
fibre carpets.
– Observe the
manufacturer's carpet
declaration.
– If in doubt about the
colour-fastness, apply
a small amount of
cleaning agent to the
carpet in an
inconspicuous place
using a white cloth. If
the cloth picks up the
colour, the carpet is
not colourfast.
CARPET PREPARATION
• Before starting the
spray extraction,
vacuum the carpet
thoroughly.
• Pretreat spots or
severe soiling with a
special cleanser or
spot remover.
USE FOR NORMAL
SOILING
• Start cleaning the
carpet in the corner
furthest from the door.
• Turn on both ON/OFF
switches for the suction
unit and the pump
(TW 300 S: Fig. 2c
TW 350: Fig. 5b)
• Position the spray
nozzle at the edge of
the carpet and actuate
the metering valve.
• Pull the nozzle
gradually backwards
(1 m in 5 seconds),
apply slight pressure
to the hand tube.
• Shortly before
reaching the end of a
stroke, close the
metering valve and
pick up the water last
sprayed.
• The next working
stroke should overlap
the previous stroke by
approx. 2 cm.
• The drying time can
be shortened if the
carpet is sucked off
again with the spray
extraction unit.
