Do not reach behind or move the equipment to unplug it. Wet electrical surroundings require appropriate help to make the situation safe.
What the observation means
Stopping fixture use limits further inflow but does not by itself remove the electrical hazard. A safely accessible upstream isolation method may be relevant, but it must be identified appropriately.
A useful next step
Keep others away and explain the wet floor and inaccessible socket when requesting assistance. Do not dry the area with a mains appliance, pull a cable by its cord or restart the pump because the visible puddle has been absorbed.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
