You may have seen upright glass washers in action at busy coffee shops and leisurely bars.
These handy little machines are made specifically to clean any item of glassware in a matter of seconds through a series of spinning brushes that work producing a squeaky clean glass.
They take all the fussy hard work away from staff who can then use their time to attend to more productive tasks, such as serving customers.
So you might wonder why you would want to use one of these when an industrial glass washer could clean hundreds of glasses per hour.
Well, you see, industrial models are good at what they do, but they have a number of disadvantages in that they take several minutes to complete a cycle and they produce hot glasses that need to cool down before they can be re-used.
An upright washer on the other hand cleans an individual glass in seconds which can immediately be served.
So you can see that a hand glass washer can be preferable in establishments that have a low but constant stream of customers, like in cafes, for example.
Other places where an upright washer make sense are at busy bars where customers can't be kept waiting for a clean glass.
Industrial glass washers are great at what they do, but manual glass washer have their own set of advantages as well.
They are faster when it comes to a few glasses, they clean a little bit better, and they enable glasses to be immediately served back to glasses as there is no cooling off period.
The next time you are in a busy bar and you see an appliance with multiple brushes sitting in the sink, chances are that it's an upright glass washer.
