Spray extraction two-step process (indirect method)
Removing heavy, stubborn, deep-seated soiling from floor coverings in two work steps using the spray extraction machine. Suitable for water-resistant, textile floor coverings, carpets, textiles or upholstery.
Preparatory work
Select suitable products to match the surface to be cleaned (type / square metres) and the type of soiling.
Check whether the entire floor covering is water-resistant.
Check, equip and ready the machine and all accessories in compliance with the instructions for use.
Fill the pressure sprayer with the cleaning product in accordance with the dosing instructions. Close the pressure sprayer and build up pressure (pumping). Fill the fresh water tank of the spray extraction machine with clear water.
Put up the warning sign.
Remove any loose dirt (dry vacuuming or brush vacuuming).
Main task
1. Work step (prespraying)
Use the pressure sprayer to evenly spray the textile floor covering with a sufficient amount of cleaning product solution, working in slightly overlapping passes.
Allow the cleaning product solution to take effect, but don't let it dry.
2. Work step (spray extraction / rinsing)
Spray extract the textile floor covering with water. Moving in slightly overlapping passes, pull the spray extraction nozzle slowly backwards, spray the pressurised water into the floor covering via the spray nozzles and immediately remove the dissolved dirt and the remaining cleaning solution using the suction nozzle. Repeat the process until the vacuumed rinsing water runs clear.
Empty the waste water tank when it is full. Refill the fresh water tank when it is empty.
As needed: Straighten the moist carpet pile using a carpet pile brush.
Perform a visual check.
Allow the textile floor covering to dry completely.
