#1385: CleanerShield

Today’s invention is a modification to those conventional (and pretty effective) vacuum cleaner bags that many of us still use.

I’ve noticed that sucking up fragments of rubble and sharp debris tends pretty quickly to make a hole in the side of the bag opposite the inlet (rendering the whole device temporarily useless).

The idea would therefore be to place a cheap, multilayer cardboard pad on the inside of the bag at the impact location. This would effectively resist damage whilst not limiting too greatly the flexibility or the air-permeable area of the bag itself.
