Self-sweeping floor
A moving pattern of static electricity shoves the dust aside
  (+8, -1)
(+8, -1) 		  [vote for,

This deals with hard floorboards that have an electrical layer just beneath the top layer. The layer is organized in parallel tracks. Each track can attract dust and can repel dust. By activating the tracks in a specific order the dust is moved to the side of the room. All you have to do is to remove the dust that is collected at the side of the room.

Looking at the floor from the side (you see a cross-section, the short end) the pattern can be described as: Normal (neutral): 00000000000000 Step 1 : -+00-+00-+00-+ Step 2 : 0-+00-+00-+00- Step 3 : 00-+00-+00-+00 Etc. Description: 0 = no attraction or rejection - = Rejection + = Attraction

Undoubtedly the exact pattern has to be determined via trial-and-error. Who knows you find interesting patterns in dust, e.g. dust-circles?

Note: I am open to any suggestion how static electricity can be used. Unfortunately I have no clue anymore, those schooldays have long gone...

       I like the idea... just make sure the stuff is earthed after it has finished cleaning else you might have problems with sparks or at least find your hair standing up a bit...

       Since probably not all the dust particles are charged, maybe an iron-backed, handleless, flat broom could be moved around the floor by the fields.
