If you were cleaning on "allergy gounds"and what you posted, is what you did, you will not have resolved an "allergy" problem, simply by vacuuming, in fact, aggressive vacuuming is likely to worsen the problem, if done with a machine which has paper or cloth bags.
Sure...........you will pullout a lot of cut pile and accumulated dust, but you will also return the worst of this, the finest particles , to the atmosphre, only to land back where they started.
The only vacuum which effectively removes tiny particulates, is one with water filtration, which captures the soil and prevents it returning to the atmosphere.
Not criticising the effort, which was undoubtedly done with good intentions, but question the outcome.
To treat an allergy, you have to know the cause of the allergy, of whic there are many and it's a bit dodgy to make claims which can't be substantiated.
As I said. This is not a criticism of Alan Brooker, or anyone else who follows this route.
The specific targetting of dust mite elimination and control, is a safer approach, when offerng such a service, as there are specific products, with a proven history, over the past decade which can be used, rather than give false hope, to people with a non specific problem.
