A swimming pool cleaning device is disclosed herein. The device includes a vehicle having a body shell and an interior and at least one intake port located on the body shell. The vehicle includes at least one water outlet port also located on the outer shell. The vehicle includes a drive mechanism which in different embodiments includes pairs of wheels and/or rollers or a combination of wheels and rollers for moving the vehicle along the pool surface. In one embodiment, the intake ports are located in close proximity to the drive mechanism. This assures the intakes of being consistently close to the pools surface as the vehicle moves. In another embodiment, the vehicle has a concaved bottom. The concaved bottom points towards the interior. In this embodiments the intakes can be located slightly farther away from ends of the vehicle as a result of the curvature of the bottom while maintaining sufficient sucking power to clean the pool water.
