An apparatus for removing standing water from a large surface area includes a housing capable of being moved across the surface area. An elongated rolling member is mounted on the housing with its elongated axis transverse to the direction of travel of said housing over the surface area. At least a portion of the rolling member is located on the underneath side of the housing. The rolling member has a nonwater absorbing wear resistant surface enabling that portion of it located below the housing to contact the surface area to be depleted of water. The rolling member rolls on the surface area to displace water to a position in front of the rolling member and form a moving wave of water in front of the rolling member. A wave direction changing member is located in association with the rolling member in front of the rolling member. The wave direction changing member imparts a momentum to the wave of water maintaining the wave of water on the underside of the housing. A component of the momentum imparted to the wave of water is directed transverse to the direction of travel of the housing towards one or the other of the ends of the rolling member.
