#1275: MatrixMat

Today’s invention is a doormat which consists of a flat matrix of short, vertical, plastic tubes all of which are sealed into a base tray.

The tray is connected to a vacuum cleaner device.

When someone is sensed to have stepped onto the mat, the vacuum cleaner motor starts up and draws air down through the matrix of tubes.

This extracts from the feet of the visitor a large volume of dust and debris which would otherwise be walked into carpets etc. This collected mess can occasionally be tipped from the tray into a waste bin.
