"Cleaning escalators is a tiresome business, tedious work that can only be effectively done by hand."
Who said that? Queen Victoria, perhaps? Genghis Khan? Julius Caesar, maybe?
Whoever it was, it's a pity they couldn't have looked at the 21st Century way of cleaning escalators!

True, manual cleaning is very thorough and gets right down into the grooves of the treads - but look at how long it takes! For an average escalator, 6 man-hours to do a good job? And the escalator needs to be closed off all the while he is doing it.

With the Duplex escalator cleaners, the 6 man-hours are reduced to about 30 minutes. Deep cleaning, using water and detergent, gets right down into the grooves and brings back the original sheen that you had quite forgotten was there. And the Duplex also sucks up all the water again.

Are you worried about using water on an escalator? Don't be! Just think of big cities around the world on a rainy day. How many thousands of litres of water are carried into the London Underground, the Paris Metro, the New York Subway on peoples' raincoats, their umbrellas, their shoes and briefcases, and then deposited on to the escalators? These modern contraptions are designed for these conditions.

And this is why the Duplex machines (they come in 35 cm. and 55 cm. width) are the modern answer to a modern problem and why they outsell dry machines, which grind and scour and thump and create a lot of dust.

And don't forget - travelators can be cleaned just as easily.
