THIS electric duster is an unusually efficient device which makes dusting easy, quick, and thorough. Of British Make, it enables the housewife to thoroughly clean upholstered furniture,

draperies, mattresses, books without removing them from their shelves, doors, window-frames-in fact, all the places that are so tiresome to get at, and, that without troubling to attach dusting tools to the electric cleaner. It will provide draughts of air for the purpose of blowing up pillows, eiderdown quilts, the operation of sprays, for the removal of dust anywhere. Fitted with swivel joints, it is light and convenient to handle, and invaluable where time is precious and ease of cleaning is desired. Royal Purifier. ewe POWER, universal electric motor; amps, 1.8. Running tests: .415 pence per hour at one penny per unit. No. of accessories, 11. Length of suction hose, 9 feet. Price, £18/18/-. Thie newly-arrived electric vacuum cleaner is designed with the aim of lightness and portability, and at the same time incorporating every necessary cleaning feature. Great vacuum strength is used to remove the dirt and grit from the carpet and to draw right through the mesh any dust that lies between the carpet and the floor. An air speed of 180 miles per

hour is attained from the suction end if the passages are not restricted. A brush with three’ adjustments is permanently fixed to the carpet-clean-ing nozzle. For cleaning earpets, the adjustment is set so that the brush is flexibly mounted on light springs and will exert little pressure on the carpet pile. If the brush is not required, it may be withdrawn from usage or it may be set stiff so that in cleaning floors and linoleum it exerts a scrubbing pressure. A felt-covered polishing pad may be attached to deal with polished floors. & A chamber is set in the nose of the

machine where crystals of a camphorsmelling nature’ are placed, and they bring into the air of the room a pleasant odour. The most valuable new accessory is an atomising receptacle to hold a liquid, which acts both as a disinfectant and \a destructor of insects. . It is like the ap. paratus used for spraying duco paints on the modern motor-car and can be used to spray varnish and light lacquers over woodwork,
