SOA Deep Cleaning Extractors and Systems Provide Superior Results
Regular professional cleaning is as important to your carpet as having a trained mechanic perform routine maintenance on your car. What vacuuming and spot cleaning miss, extraction cleaning should fix. CRI tests deep cleaning extractors and deep cleaning systems: the ones professionals use. The extractor is the machine, while the deep cleaning system is the combination of that machine and a particular cleaning solution, following a set procedure.
Careful Measurement Leads to Superior Performance
The CRI Seal of Approval program tests the effectiveness of deep cleaning extractors and systems. To qualify for the Seal, extractors must meet stringent standards in all three test categories:
If a system is being tested, additional test criteria are included and mirror those from the Cleaning Solutions protocol. These include the following:

Additional technical testing information
Testing for soil removal: To test for soil removal performance, the independent laboratory uses a “designer” soil that has properties similar to soil found in carpet across the United States. A significant new element to this testing protocol is the use of x-ray fluorescence (XRF) technology, which was developed by private industry and enhanced by NASA for the Space Shuttle program. XRF enables the laboratory to identify and quantify the various compounds found in the soil. Using the XRF analyzer, laboratory staff measure the starting concentration of each compound applied to the carpet sample (following ASTM protocols) and, following cleaning with an extractor, quantify the precise amount of soil removed.
Testing for residual water: To measure how well an extractor recovers water, the test carpet sample is weighed before and after the standardized process to determine how much water remains.
Testing for texture retention: Finally, surface appearance change in the carpet pile, as a result of extraction cleaning, is measured using CRI’s Texture Appearance Retention Reference Grading Scales, which provide a visual aid in assessing appearance change in carpet.
