The Floor Scrapers is the first time workers are the main focus of a painting.
Like the Realists and Impressionists, Caillebotte was fed up with representing historical subjects.
He wanted to represent the real world, as it appeared to him.
The painting pays tribute to men who embellished the interiors of Parisian apartments, at a time of profound transformation of the city.
Indeed most of the Paris we know today dates back to this period.
It was a period of dramatic change, led by the famous Paris prefect Haussmann.
Haussmann gutted Medieval Paris, drew up new avenues, created parks, monuments, train stations...
Under his watch, 34 000 new buildings were erected, 600 000 new trees planted - with strict architectural guidelines, giving rise to the architectural style we associate with Paris today.
The Salon, the most prestigious art competition of the time, rejected Caillebotte's painting, judging it vulgar and of no interest.
But Caillebotte went on the become one of the leading figures of Impressionism.
