Vacuum Cleaner Grid:

I use disposable paper bags on my vacuum cleaner. I realized that as soon as the vacuum cleaner starts, the bag surface close to the suction area keeps in touch to it and all air flow happens only over this contact surface. By adding a grid that prevents the bag be directly in touch to the suction area, the suction flow happens trough all bag compartment and all area around the bag is used. This increases suction power and efficiency.

Laundry Machine Filter:

The original filter from my laundry machine is not good. The cotton hairs quickly cramps its holes making it loose efficiency.

First Version: Very good result! It is necessary make the filter with something like a woman's silk stocking.
