Abstract: The invention relates to a probe for sampling a drilling fluid comprising a handle extending along an axis, and a sampling head located at a first end of the handle, the head defining an inner space opening outward through an opening. The head comprises a filtration device comprising a filtering wall disposed through the opening; and an extraction duct extending into the handle and opening into the inner space of the head. The filtration device comprises a cleaning blade designed to sweep an outer face of the filtering wall, the blade being mounted to move in translation in a direction parallel to the axis.
