WET CLEANING DEVICE

A wet cleaning device (WCD) comprises a mopping unit (MU) for wet cleaning a surface, and an arrangement (ST) for increasing a pressure of the mopping unit (MU) to the surface by means of suction. In one embodiment, the arrangement includes a hose at a side of the mopping unit(MU), the hose having an opening for applying suction to the surface. The hose may be present at opposite sides of the mopping unit(MU). Alternatively, the hose may be present around the mopping unit(MU). Preferably, a suction power of the arrangement is controllable. Advantageously, the suction power is controllable in dependence on a detection of stains, a speed of the wet cleaning device (WCD), and/or a type of the surface. If the wet cleaning device (WCD) is formed by a mopping robot vacuum cleaner, the suction for the arrangement (ST) is advantageously a part of a suction generated for vacuum cleaning.
