Focus on the actual process, material, residue, extraction, and drying—not one marketing term.
Hot water extraction
The process often called steam cleaning applies and extracts a water-based solution.
Shampooing varies
Some use the word generically; others mean a specific foaming or agitation process.
Material decides
Fiber, backing, installation, soil, and manufacturer guidance should inform the method.
Ask better questions
Ask about inspection, spots, residue control, and drying conditions.
