Have you ever heard guys bragging about how they have been using the same machine for the last 25 years? Just regular services and it will go on forever.
There may be a sentimental note in those words but are those guys doing themselves a favour? And isn’t that “eternal” machine running on one vacuum motor with a mere 50 - 70 psi? Most likely it is. They despise the new 2 and 3 motor machines with powerful pumps capable of 300, 500 psi.
So why do you need that power and extra cost? Those new machines are expensive, larger, heavier. I can do the job with my current 25 year old trusty.
The answer is very simple. With a more powerful machine you can leave the machine outside the house or on the ground floor without having to sacrifice pump pressure and suction. You can run longer hoses just like a truck mount but without the cost of the truck mount. You can have an in-line heater heating up water just before the wand. Most importantly you will not have to lift your machine up steep staircases (carpet cleaners‘ worst nightmare :-)) and still do an excellent job at a fraction of the cost of a truck mounted carpet cleaning system.
Time to change those trusty rusty steel buggers, guys. I still see quite a few relics on the streets though :-).
