Hi Gwyn,
When you say the 'Von Schrader' range, are you talking about their dry upholstery cleaning range (the 'Aridex' and 'Esprit' dry foam upholstery cleaning systems), or are you talking about the 'HOST' machines and systems (purely for carpet cleaning) ?
Host Von Schrader currently brand their carpet cleaning machines and systems under the 'HOST' brand, and their dry foam upholstery cleaning machines and systems under the 'Von Schrader' brand.
Two very different systems: HOST uses dry compound method for cleaning carpets. VON SCHRADER is a dry foam detergent method.
As a full time carpet & upholstery cleaning business, I personally wouldn't limit myself to either systems, however if you are looking to work part-time and just do the dry systems (which are MUCH easier to learn and operate) then staying purely with the dry methods would be fine.
Some franchises operate exclusively with dry systems (Bone-Dry and Zero Dry Time being two of them) but marketing spends are high in order to get the required target customers who want this type of service.
Also, dry machines are usually much more expensive that entry-level HWE machines. The HOST Freestyle for example costs £3499+VAT
In my business I offer three methods of carpet cleaning: Hot Water Extraction, Bonnet Carpet Cleaning, and Dry Compound. For Upholstery cleaning I offer Hot Water Extraction and up until today the ARIDEX system from Von Schrader. However, I am personally not satisfied with the results from ARIDEX, and considering it's price (£2,700+VAT) I cannot justify it, when HWE works fine in most cases of upholstery cleaning. Ian Monk of Clean Machine has therefore kindly agreed to exchange my ARIDEX system for a new back-up Hot Water Extraction Machine!
For Dry Compound, I use the Envirodri system, which is similar to HOST. I bought a brand new Envirodri GEN4 machine last week (from John Williams at CareClean UK) for around £950 and it is superb in operation and build quality. I also prefer Envirodri's sponges as I find them just as effective as HOST, but easier to vacuum.
I do about 50% How Water Extraction cleaning and 30% Dry Compound, and 20% Bonnet Cleaning in my business.
I hope this bit of insight into the dry methods has helped. If you market and proposition it correctly, dry carpet cleaning can be viable on it's own but you can't do it effectively with entry level stuff like a £200 Sebo Duo and a 1kg bag of HOST! ;Dv ....... up front investment is usually more for a dry system than wet but the business model is easier and the risks lower.
Cheers,
David
