Carpet cleaning machines used professionally (every day) tend to break down. The only 2 bits of machinery you are most likely to repair/change are the vacuum motors and the pump.

If you ask me I would buy a few motors and pumps and change them myself or find someone to do it for me. If you go to a proper carpet cleaning repairs company they will charge you about £150.00+VAT for a motor change and about the same for a pump change. That is expensive and even more if you are not VAT registered like most sole trading carpet cleaners. Carpet cleaning becomes expensive business to maintain machinewise but you have no choice but live with it and look forward to the next nice paying job.

From my experience nearly 5 years now, I would say that the Alltec Advantage has been for repair the least times compared to my other machines. Most problems I have had with the Prochem Steempros. Mainly due to their breakdownability I decided to stock on pumps and motors :-)
