I recently contracted Drymaster to steam-clean both a micro-suede lounger suite and a 2 BR apartment. The quote was mid-range. Certainly not the cheapest and also not the most expensive. The contractors spent about 90 mins on the lounge suite and did a fair job. They then spent around 70 mins steam-cleaning the entire apartment & rugs. The original carpet cleaning job was appalling.
I was told dirty marks in traffic ways which had not been removed were 'ingrained' and that spots cleaning I had previously performed myself had 'bleached' the carpet when I pointed out that the spotted areas could still be seen because the operator had not cleaned the surrounding dirt. Both assertions were complete rubbish, indeed intentionally misleading, which I proved by prompting spotting out dirt in areas supposedly 'cleaned' by Drymaster.
When I said I was not going to pay the invoice for the carpet cleaning, the operator after a heated exchange remained back for a further hour and did a marginally acceptable job redoing all the areas where I could still see dirt. Certainly the areas I disputed were much cleaner after repeat cleaning.
My frustration is that many customers would simply accept the rubbish that the original job was as good as they could do. Fortunately I have had quite a lot of experience using supermarket steam machines such the Britex and I know exactly what dirt is ingrained and what is not. I'm also a professional scientist and can call out intentionally misleading claims such as the assertion that spot cleaners I used contained bleach which they do not. Indeed the difference is colour was simply the fact that the carpet had returned to its original colour in the areas which I had spot cleaned which was evident after re-cleaning.
And overall it was still not the job that I know I could have obtained myself with a supermarket steam cleaner. Which is what I will probably use next time if my experience with Drymaster as 'state of the art' professional carpet cleaners is anything to go by.
