Yes, when cleaning vertical surfaces (eg. sides of sofa/chair), uneven surfaces (e.g. leg room of car cabin), or fabric surfaces with slopes (e.g. ottomans or car seats), you may use the Flexible Hose & Handheld Nozzle attachment together with the Cordless Upholstery Fabric Cleaner. It offers you higher flexibility when cleaning hard-to-reach areas, given that the main unit is not tilted during operation.
Do not use the Nozzle for dry vacuum. Use the sprinkler on the main unit to wet the cleaning area first, then suck up the dirty water using the Nozzle. Or you can also use a damp cloth to wet the target area for subsequent cleaning.
