Expensive Machines Are Not Always Better

When examining the design of even the most expensive vacuum cleaners, we noticed a serious flaw that can only be expressed as an "intentional design omission".

For air not to escape from holes or filter edges, the vacuum cleaner should be equipped with special packing devices. We noticed that air is often emitted from unexpected areas such as the box around the electric cord, or near the on-off switch. Perhaps by letting some air escape even a little, the designers aims to raise suction force. However, this also means that it is useless to equip the machines with High Efficiency Particle Air (HEPA) filters, since dirty air will leak from other holes in the body of the vacuum cleaner.

Japan Offspring Fund has expressed the opinion that even some of the most expensive vacuum cleaners sold for home use in Japan are dangerous for people suffering from allergies.
