DUAL CLEANING TECHNOLOGY

The machine offers two cleaning technologies,

Restorative Extraction and Soil Transfer Extraction

which is referred to as ReadySpace. 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.

ReadySpace: 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.

Spray

Nozzles

Vacuum

Shoe

Brush #1 Brush #2

Machine Direction

ReadySpace: 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.
