Hi Angelo I use LTT and have been happy with their products, apart from the deep cleaner which appears to have developed a dog like smell, but to be fair once cleaned and dried the odour goes.
Furniture Clinic are also great and do good products. So if you are using those I am surprised your not happy.
The other is buffalo which I have not tried but they are helpful and people I know who are in the know say their deep cleaner is very good.
Money wise Buffalo are better value as you can buy 1 ltr of concentrate which will dilute to 10.
Hope this helps
