A constant nuisance when vacuum cleaning are cables (see above image) since they easily get tangled up and catch dust. I always wondered, why there is no widely available system of e.g. adapters hooked directly to consumer electronics in order to avoid too much “cable spaghetti” – analogous to the solution of a computer blade.
People from IBM made this instructive video in order to display that blades could still include in principle a noble solution.
