Surfaces and compatibility
For carpets and textiles whose fibres, backing and installation permit spray extraction. An approved upholstery or stair tool may extend the applications when suitable for both machine and textile.
With a listed 7 L recovery tank, 8 kg weight and hand tool, this format is primarily suited to targeted work.
Preparation and use
- Dry vacuum, identify stains and clear the area. Test colourfastness.
- Inspect the cord, seals, hoses, filters and tank levels.
- Select detergent, temperature and attachments according to the textile, chemical and machine instructions.
- Use consistent passes. Avoid unnecessary rewetting and perform the specified recovery passes.
- Monitor tank level and foam during operation. Allow complete drying before returning the area to use.
Care and storage
After use, empty and rinse tanks, clean jets and remove fibres from the head. Flush the circuit as instructed, inspect seals and dry components as prescribed before storage. Unplug before maintenance.
Limits and things to check
Higher pressure alone does not guarantee better cleaning: recovery, flow, textile and technique also matter. Weak suction may result from a full tank, misplaced seal or blocked hose. Drying time cannot be guaranteed by the model alone.
