Get a plain-language description of each method
Ask what equipment is used, whether moisture or cleaning solution is applied, how any material is recovered and what aftercare is expected. Ask providers to define their terms consistently so you can compare like with like.
Match the process to carpet construction
Provide the carpet fibre, backing, installation details and care instructions if available. Ask each provider to explain why its proposed method is compatible and what test or assessment it performs. If the material is unknown or delicate, contact the manufacturer or a qualified carpet professional before treatment.
Compare job-specific scope, not generic claims
List the area, type of soil, stains, previous treatments, furniture, access and scheduling needs. Compare inclusions, exclusions, spot treatment, product information, aftercare and price on the same basis. Do not assume low moisture always means quicker drying or that another process removes all residue.
Avoid unsupported performance and health rankings
No universal claim is made that one method cleans better, dries faster, prevents mould, removes allergens, sanitises carpet or extends its life. Such outcomes require substantiation for the exact machine, product, method and carpet.
Choose after the provider confirms suitability
Request the proposed method and limitations in writing. If providers cannot explain compatibility with the carpet-maker guidance, seek independent specialist advice before booking. A cleaning appointment cannot repair backing, replace carpet or guarantee a bond result.
