I've been going on for years to anyone who will listen that I would pretty much pay anything for something that would pick up Lego off the floor - that would suck it up and sort it without dust balls, dog hairs and other disgusting things. The problem is that I have absolutely no idea how to invent such a gadget.
However - I have just discovered the perfect solution - a website called Quirky (I've just discovered it but you may all know it already) where you pitch your idea and if it gets 200 votes, someone will actually build it for you!
So I would love it if you would vote for my Lego vacuum idea and with any luck, we'll save the backs of the next generation of parents ...
