Background

Today's surface cleaning devices are used for wet cleaning hard floors or short-hair carpets. The device typically has one or more rolling brushes or cleaning discs made of a wool material which can scrub tough soils on the floor by adding water or a water/cleaner mixture. When the machine moves over the dirt, the dirt that has been wiped off by the roller brush and dissolved by the water or water/detergent mixture is sucked up with the cleaning head arranged in the direction of movement of the roller brush, and in the technique of providing the cleaning tray, the cleaning head may not be provided and the dirt is directly adsorbed by the cleaning material on the cleaning tray.

However, stubborn stains are often difficult to clean, as dairy stains, juices, sauces, and the like, are scattered on the floor surface, and often include not only dirt particles on the floor, and often the cleaner head is designed to remove large particulate matter (e.g., rice grains, hair growth, and popcorn) from the carpet, so when using a wet surface cleaning device to clean the floor, it may be necessary to have the dirt and solids sucked into the dirt box of the surface cleaning device together.
