PORTABLE HARD SURFACE CLEANING DEVICE

The invention relates to a portable hard surface cleaning device (10) provided with a handle (70), a suction turbine (22) arranged above the handle (70) in a housing, a suction nozzle (18) which is fluidically connected to the suction turbine (22), and a dirty liquid tank (20) which can be releasably connected to the housing (12). Liquid can be separated from the suctioned liquid/air mixture and deposited in the dirty liquid tank (20), and the dirty liquid tank (20) has a first tank region (98) with a tank opening (104), said first tank region being insertable into a first tank receiving compartment (76) arranged laterally adjacent to the suction turbine (22) in an offset manner relative to the handle (70). The aim of the invention is to develop the portable hard surface cleaning device (10) such that the device has a lower energy requirement. This is achieved in that the suction turbine (22) is fluidically connected to the first tank receiving compartment (86) via at least one exhaust air opening (80, 82, 84), and exhaust air can be dispensed into the surroundings via the at least one exhaust air opening (80, 82, 84) and the first tank receiving compartment (76).
