A nine inch disk with brush bristles is attached to a doormat. The brush is powered by a 1/3 horsepower industrial waterproof motor that spins at 2500 RPM (rotations per minute.) The doormat plugs into a waterproof outdoor grade outlet with a water resistant cord. If your house does not have an outdoor outlet, there are waterproof extension cords available that you can hang out of the window. The disc brush can be turned on and off by an electric sensor that detects if a foot is on the doormat. When the bristles wear out, you can unscrew the old disc from the motor and put on a new disc brush. If there were more of these, We would not have to worry about staining other peoples floors. The doormat can be used indoors or out. It can also be fitted with a shoe buffer attatchment for when you need a shoe shine.-- non-eatable, Aug 13 2002 Combined boot cleaner and shoe shine http://www.pilgrims...ine_machines_d.html [DrCurry, Aug 13 2002] End Soliciting http://www.halfbake...etal_22_20DisruptorIt doesn't zap, but it still fries nerves... [Mr Burns, Aug 14 2002] Spinning brush shoe shine machines are thoroughly Baked, as are spinning brush boot cleaners. In Europe, where shoe-shine professionals are rare, coin-operated versions are often placed in public places. The ones in corporate bathrooms are either pressure sensitive or push-button operated.
Haven't seen any attached to doormats, but I fail to see the advantage.-- DrCurry, Aug 13 2002 If you're standing on the disc, wouldn't you also spin around?-- Mr Burns, Aug 13 2002 <pout> I was kind of hoping this would be a wired doormat to zap Salesman and unwanted Jehovahs Witnesses with ..... </pout>-- The_Englishman_Abroad, Aug 13 2002 thcgenius, if you only put one foot on the disc, you wouldnt spin. Weaker people might have to install a wall-handle. Englisshman Abroad, If I get around to it, Ill think of a jehovas witness and salesman door zapper. Unless you think of one before me. Dr curry, that link was not what i was thinking of. Besides, its not water proof.-- non-eatable, Aug 13 2002 I think this idea would make a nice centripetal girl scout ejector.-- polartomato, Aug 14 2002 You must mean centrifugal unless you want a girl scout injector.-- FarmerJohn, Aug 14 2002 Aww dammit... I always mix those up. But a girl scout injector would be cool too.-- polartomato, Aug 14 2002 Rather than a spinning disc, how about a large number of horizontally-mounted long thin roller brushes that alternately rotate in opposite directions ? Then, the cumulative force on the shoe would be near enough zero, but the sole of the shoe would get a thorough brushing.-- 8th of 7, Aug 14 2002 That's going to be rough on the barefoot beggar brigade!-- pfperry, Aug 14 2002 T_E_A- Shameless plug [linked] for other idea... it doesn't zap, but it will still clear your porch for you..-- Mr Burns, Aug 14 2002 [admin: I've got email from someone who wants to talk to the author of this idea (not sure what about). If you're the author, and you don't mind being talked to, please get in touch with an email address where you can be reached. Thanks!]-- jutta, Apr 10 2009 random, halfbakery
