DUAL CLEANING TECHNOLOGY
The machine offers two cleaning technologies,
Restorative Extraction and Soil Transfer Extraction
which is referred to as ReadySpacet. By using both
technologies you can easily develop a cleaning
program to greatly extend the use-life of your carpet.
With the simple exchange of a vacuum shoe and two
rollers or brushes you can easily switch from one
technology to the other.
Restorative Extraction: Use this technology
periodically to thoroughly clean to the base of the
carpet. The amount and type of daily traffic are
important factors to determine how often restorative
extraction should be performed. This type of cleaning
should be planned in advance to allow enough time for
the extracted carpet to dry.
ReadySpacet:Use this technology to clean visible
soils on a daily basis or as needed to maintain a high
level of carpet cleanliness. ReadySpace may be used
during normal business hours because often the
carpet is dry in less than 30 minutes. Drying time may
vary due to carpet type and climate conditions.
NOTE: Before using ReadySpace, first use restorative
extraction if carpets are heavily soiled. Then begin
your ReadySpace cleaning program.
HOW THE DUAL TECHNOLOGY WORKS
Restorative Extraction: Hot water and cleaning
detergent from the solution tank is sprayed directly
onto the carpet. As the machine moves forward, two
counter--rotating chevron brushes agitate the solution
deep into the carpet. As the machine continues to
move forward, the vacuum shoe recovers the dirty
solution out of the carpet.

Machine Direction
ReadySpacet:Cleaning detergent is pre--sprayed on
the carpet with the use of a pump--up sprayer. After
allowing the detergent to dwell for about 5--10 minutes,
the machine is then put to work. Hot water is sprayed
directly on two counter--rotating nylon fiber rollers, not
the carpet. Then much of the water is removed from
the rollers using two vacuum shoes, leaving the rollers
damp. The damp rollers then agitate the carpet,
working both sides of the carpet fiber, at the same
time transferring the soil to the rollers. Again, hot rinse
water is sprayed on the soiled rollers allowing the two
vacuum shoes to easily extract the soil from the
rollers.
