Goron, you are right in that the Drimaster is a form of hwe but as far as I know that it is rotary it is still not recomended but that is what I think again I dont know. With regards using it I wouldnt for reasons I have explained before, I get paid to well to use a Drimaster and have to do "normal" work again................................... Arthur I dont take offence at anyone particularly yourself as you are generally asking on things you need an answer too not to cause an argument....... with regards your comment on Drimaster, see above................ I will send you an e-mail as to clean off stipulations to save maybe causing a riot on here................... I am not into computers too much and wouldnt know how to send you to where but I am sure someone else on here knows how too. Other than that just look on Shaw's web site where they recommend hwe.....Interface Tiles also recommend hwe, as do Collins and Aikman, as do Tandus.............. The fact that between these companies they provide, I think so dont quote me on it, over 60% of carpeting through out the world then that would suggest that most cleaning should be hwe. There are company's that dont recommend any type over another and that used to be about 20%...... at this point we are at 80%.......With only 20% left, there to my knowledge is still no company that suggests any other type of cleaning other than hwe........ Just as a talking point lets say these 20% of company's suggested any form of cleaning other than hwe extraction and to say the obvious that would leave 2 in 10 customers...... The fact that most people dont even clean their carpets then it will always be easier to find a customer with hwe as your arsenal....... When comapany's over here start to do as they do in the U.S....... suggest to the public to have their carpets cleaned at least once a year and by hwe then life will be so much easier for us as cleaners, as the public will know they should clean their carpets and also how they should be cleaned..... It is always open to debate which is a good thing but again, let me know of any supplier or manufacturer that recommends any other form of cleaning other than hwe and I will by all means listen to their argument, till then I shall clean as requested to with hwe...... If all machines cost the same amount of money, what do you think would sell the most and be honest. I know we all need different machines for spotting and upholstery but I think you know the idea of my question..... Best, Dave....
