Ask the provider to describe the exact method
Request the process name, whether it uses compound, encapsulation, absorbent media or another method, what equipment and product are used, and what parts of the carpet are included. Marketing terms alone do not establish the procedure, amount of moisture or likely result.

Check carpet-maker compatibility
Identify the carpet fibre and care instructions if available. Ask the carpet manufacturer or qualified carpet-care professional whether the proposed product and process are suitable for that material, backing and installation. Do not assume that “dry” makes a method appropriate for every carpet or stain.
Compare the scope and limitations
Explain the type and location of soil, prior products, wear and any moisture sensitivity. Ask what the provider expects to address, what is excluded, whether spot treatment is separate and what aftercare applies. Results can vary; no method guarantees complete soil or stain removal, sanitation, allergen reduction or fixed drying time.
Choose by the task, not a blanket ranking
Dry/low-moisture, hot-water application and extraction are different processes. A qualified provider should explain why its proposal fits the specific carpet and request. Ask for another assessment if the method, equipment or product compatibility is unclear.
Keep carpet work separate from health claims
Carpet cleaning does not diagnose allergy, indoor-air or health concerns. For a health question, consult a qualified health professional; for building or product concerns, contact the relevant maker or specialist.
