Technology limitations?

Reading through the papers, I saw a headline that certainly did its job as it caught my eye, "just vacuum the dog" it claimed. A copy is available here

Upon reading further it was an attachment to your normal hoover created by Dyson that allowed you to hoover the dogs loose hairs straight off them so that they didn't drop onto the carpet.

I am a bit dubious about this gadget, it is supposed to help house-proud owners, but can you 'over-hoover' the dog? It already states in the article that it is not suitable for nervous animals. I cant really see a dog who's aggravated by the normal hoover noise letting you anywhere near him waving a hoover with a new attachment on the end.

I understand that this is a problem (dog hair on carpet) but i don't think the solution is quite finished yet. I see the idea but i don't think its ready. Although dog hair is a problem for many people, is this a situation where the technology doesn't help the problem at all?

Is society realising that technology can't solve every problem?
