A cleaning device for cleaning a floor, comprising:

• a brush assembly;
• a main body coupled to the brush assembly, the main body comprising:
• a fan with an air outlet,
• a front air outlet channel, and
• a rear air outlet channel spaced from the front air outlet channel and directed towards the floor behind the brush assembly, and
• a switching device, wherein the switching device is configured to be movable between at least first and second states such that when the switching device is in the first state, the cleaning device is configured to enable air from the air outlet of the fan to be expelled through the front air outlet channel and prevent air to be expelled through the rear air outlet channel, and such that when the switching device is in the second state, the cleaning device is configured to enable air from the air outlet of the fan to be expelled through the rear air outlet channel towards the floor behind the brush assembly.
