A suds-making device is attachable to the air-discharge port of an upright vacuum sweeper. A shampooing unit is easily attachable to the front of the vacuum sweeper in place of its easily removed suction-nozzle and rotating-brush unit. The shampooing unit has its own rotatable brush, similarly belt-driven by the sweeper motor, and also has a forwardly positioned transversely elongated tray to receive the applied and then scraper-blade-removed suds. The suds-making device and the shampooing unit (both of known construction) are interconnected by a detachable flexible hose. Importantly, the sudser end of the hose has attachable thereto, or molded thereon, a friction-held slip-on cap for closing the outlet port of the sudser, to stop suds flow. This cap arrangement serves two purposes: (1) preventing loss or misplacement of a separate closure cap, and (2) fastening the sudser end of the hose so that the hose need not be completely removed to prevent its flopping around during suds pick-up subsequent to suds application.
