Abstract: The present invention relates to a portable device for spraying a liquid at low pressure, said device comprising a spray arm (220), and characterized in that the spray arm comprises at least one flat fan spray nozzle (230). Preferably, the liquid is a cleaning composition for treatment of carpets and other large fabric coverings, more preferably, a composition comprising surfactants. Also preferably, the portable device is electrically driven, and/or the spray arm is extendible and/or detachable from the device's main unit.

Abstract: The invention is an extendible liquid-applying spray arm for use with a liquid source, such as an electrical sprayer. It includes one handle and at least two tubular members which are telescopingly engaged with and slideable along one another. Sliding the tubular members extends/retracts the spray arm respectively for treating/storage or to meet particular work needs which require that said extendible spray arm has a short length. When the spray arm is collapsed, the telescopic members are at least partially arranged within the handle, so that the global length of the spray arm is less than the additional lengths of the handle and the telescopic portion. The spray arm further comprises a spray member for spraying the liquid. A flexible tube extends around the tubular members and connects to the nozzle member, which is preferably coiled around the tubular members.
