And general attachments made as simple as possible. Dust bag lined and sometimes partitioned. Dust bag easy to put on and take off with a collar to hold between the soles of shoes to empty without making dust escape. Automatic closing valve where dust bag collar comes off--to prevent dust flying back into motor casing. Rubber bumper to protect furniture. REQUISITE QUALITIES In short, the satisfactory cleaner must: 1. Sweep loose the adhering dirt such as thread, lint, dust particle, and brush up matted nap or pile to restore color tone. 2. Loosen and shake to the surface ground-in dirt that kills rugs and carpets, so that it can be removed. 3. Have suction enough to carry away all dirt after the soft hair brush loosens it to make it possible. This is about the whole story. And as to the expense of operation, they cost not even as much as an electric iron, and far less than the cost of extra cleaning folk to-day. Cleaning becomes interesting and the household without a maid or with one, saves time and money. The rugs can be cleaned at home and stored at home in the summer. Here you save summer’s many costs! Cleaning becomes almost a pleasure, at least a pleasanter performance, not a bug-bear--or in this case we might say--a rug-bear! It is an economy, a comfort and a gold lined investment in which the interest is health, money saved, and fabrics preserved. Could you ask for more in a sweeper? But don’t expect miracles. The vacuum cleaner needs slight pushing over the floor--it can’t roll by itself. CHAPTER V A PIPE DREAM As soon as you get accustomed to the intricacies of one method of doing anything to-day, something new crops up. This is probably more true in the realm of housekeeping than in any other except that of military science. You have no sooner mastered the points of what not to do and what you should do with portable vacuum cleaners than up comes the stationary vacuum cleaner and you have to know about it, too. And so this article after one on the portable cleaner. If you forget the technicalities see Chapter IV. To refresh your memory, every vacuum cleaner has five elements: 1. Air producer (vacuum is a misnomer): the pump or fan series employed to create the air current. 2. Dust collector: bag, box, pail, etc. 3. Dust conduit: piping. 4. Cleaning tool: brush, felt, etc., etc. 5. Human direction: the hand that steers. The portable type of cleaner has the first four parts mounted on one unit, so that the whole machine is moved in its chase for the enemy Dust. Besides this the electric wire must be applied to an electric connection in a baseboard or electric fixture.
