Spending money is scary and there's is always the problem of where to find cash. But if you can wash a rug, and have identified your potential market share, then it's time to decide if you are doing everything you can to move forward. I speak from experience. We had cash, but were uncertain how to use it to make a step up. Deciding wasn't easy.
Education was scare and the 'wisdom' of 100 years of rug washing in the US was being quickly forgotten. You called the last of the equipment producers - nice guy - and he was effectively retired; too busy playing golf to take a call. At conferences the 'old guys' had no time for you. Maybe they even told you some jive to throw you off the track (why they bothered, I don't know).
Today it's different. There are options - lots of them - and chat rooms galore parsing the smallest details; what's better, what works. Deciding what's right still isn't easy, but there are lots of options and good advice .
A Cambridge system - or one like it - is the foundation of a wash plant. An efficient drying room, with every rug extracted drip free before it goes in, yields rugs ready to drop the next morning. It's not just faster, the rugs look and feel better. Dehumidifiers, fans on rugs hanging over the wash pit, and other such compromises are fine for a while, but they are not what puts you ahead of the competition.
And no, Tom and Greg didn't pay me to say this. I learned the hard way.
