The objection that with this apparatus there is tremendous wear and tear because the hose is taken through the doorway from the hall so that the door must needs be scratched when it closes on the hose as it is dragged through, may be nullified by installing double end hose connections in the wall near the door so that one line of hose will connect from the valve to the connection in the hall and another shorter piece of hose used inside of the room. There is no trouble at all about installing the stationary vacuum cleaner after the building is erected, but naturally it is less expensive to put it in during the building and when planned for ahead than it is to put pipes through a house after it is built. OPERATION With the stationary type cleaner you have no machine to move about--you simply move the tool attached to the hose and the tools are just as light as those of the portable machines. There is no electric connection to make, no electric wire to carry unconsciously along. All there is to be done by the worker is to slip the end of the cleaner hose into the suction pipe opening in the baseboard of the room. A patented device prevents the hose from becoming detached accidentally. The usual tools come with the installed cleaner, such as handle, blower, felted sweeper, book cleaner, duster, etc. Other tools can be made to order to fit any particular need. One thing delightfully obviated in the stationary cleaner is the noise. The writer has what she considers the best portable cleaner on the market, yet the noise is a great drawback. The stationary cleaner is therefore a boon to the sick room and it is easy to see why the newer hospitals take as readily to them as to the piped water system. Then, too, having the baseboard vent in each area in large houses, with the consequent needlessness of carrying a cleaner upstairs and down, over hill and dale, is a selling point for the piped cleaner. Also the swiftness of the cleaning, due of course to the tremendous air velocity--a canned hurricane. However, in the small residence the greater cost would be unwarranted because of the great efficiency of the portable machines. Where there is a garage in the family, and it is piped for cleaning, the machinery, instead of being permanently installed, can be mounted on rollers and can be wheeled and attached to the pipes in that building. Therefore the necessity of two machines is obviated where the other building is piped. Yet when the buildings are widely separated it is best to have one of the good portable machines which are on the market in so many designs, and are adapted to so many and varied uses. Therefore you see the portables as indispensable and see them filling fields that the installed can never hope to fill.
