摘要: A removable suction nozzle inlet adapter is taught for converting the suction inlet of a vacuuming nozzle from a straight line inlet to one having either a convex or concave suction inlet whereby curved carpet and/or upholstery surfaces may be vacuumed. The adapters are particularly useful for use with hand held hot water extractor nozzles upon the curved carpet surface between the step and risers of carpeted stairs and/or the curved carpet transition from the riser to the horizontal step. Further, the invention described and taught may be used to vacuum curved upholstery or carpet surfaces found in the typical household and/or automobile.
