5. Operating Instructions
5.1 Pre-Cleaning
Before operating the carpet extractor, thoroughly vacuum the carpet to remove loose dirt and debris. This will enhance the effectiveness of the deep cleaning process.
5.2 Applying Cleaning Solution and Extraction
- Turn on the machine using the power switch on the control panel.
- Engage the brush motor (900 RPM) and spray pump (160 PSI) switches.
- Slowly push the machine forward over the carpet, allowing the high-pressure spray to penetrate carpet fibers and the brush to agitate dirt.
- Pull the machine backward over the same area. The powerful 21 KPA suction will extract the dirty water and cleaning solution, promoting faster drying.
- Overlap each pass slightly to ensure complete coverage.
- For heavily soiled areas, repeat the process.

5.3 Spot Cleaning (with Hand Tool)
If your model includes a hand tool, connect it to the designated port on the machine. Use the hand tool for targeted spot cleaning or cleaning upholstery. Follow the same spray and suction principles as with the main unit.
6. Maintenance
