Have you ever bent down in the shower and noticed how much colder the water is the lower it goes? The fact is aerated water cools quickly. That explains, in part, why first aid courses teach you to cool burns with running water.
Carpet cleaning wands suffer the same thing. The further your jets are from the carpet the cooler the water is when it reaches the carpet. And we’re not just talking one or two degrees, the difference can be much more. Single jet wands are, by necessity, so far from the carpet that the fibres are taking a cold shower. So if you know your cleaning pie chart you’ll remember that temperature is paramount to good cleaning. What’s the rule? Starting at 47˚, chemical activity doubles every 8˚. If you’ve ever had a machine that produces good heat, you’ll verify that better cleaning results are had and carpet and upholstery also dries quicker. Bonuses abound!
While we’re on wands: Apart from heat what is the other active ingredient that we should be looking for in a good wand? (Psst: it’s not pressure. That comes from a dial on the machine). What we need from a wand is very good airflow. Unless you have a liquid ring vacuum pump you will be lifting the head of your wand at regular intervals to ensure that the recovered water that is building up at the head of the wand is whisked away back to your recovery tank. Right? But are you getting the most out of your wand?
Are you using a 2” hose and 1.5” wand? Why restrict the airflow? Why not have a matching system from floor to waste tank?
These are good reasons to consider the wand you are using. We currently stock the Evolution wand for this purpose in both 1.5” and 2” which answers these issues.
The Evolution stays closer to the floor making the most of your machines heat.
