Sweeper for tile floor cleaning and floorboard, December 1926. The household revolution also concerned floor cleaning. One of the new sweeper's challenges was to find "a method for collecting dirty water besides a sponge or rag". The goal was also to avoid "the arduous act of prostration that soaked your knees, broke your back, soiled your hands and put your face right up in the dirt". The solution came from Paul Breton, the son of the ONRSII’s director. His device adapted to vacuum cleaners, which also helped to make this purchase profitable, as it was still very expensive during the inter-war period. Breton’s device was composed of a 3 to 4 liter bucket fitted with a hollow sleeve, that hooked up to a vacuum cleaner in action. The clea¬ning operation could be carried out in an upright position and even while "wearing white gloves", as pointed out by one enthusiastic reviewer.
