I'm glad this thread appeared, because I now know I'm not the only one who can't watch advertisements for these types of household appliances without my mind wandering over the actual practical uses for them (as opposed to the boring cleaning crap they were originally designed for). I am not alone, sirs!
Unfortunately the GoDuster is nowhere to be found on that webstie; however there are a few products which looks either a) ingeniously indespensible or b) so batshit insane and stupid that you HAVE to own one, just so's you can say you've got one. The StickUp Bulb is pretty ingenious; the Roll-Up Piano and Doggy Steps are firmly in the second category. None have any tickling applications, although the RotoMatic could, with a few minor adjustments :-o
