A programmable steerable robot, particularly useful for cleaning swimming pools, includes: a body member; a first ground-engaging rotary propelling device at one side of the body member; a second ground-engaging rotary propelling device at an opposite side of the body member; a rotary brush carried by the body member engageable with walls of the swimming pool for cleaning same; a drive for driving both of the rotary propelling devices and the rotary brush; a transmission system connecting the drive to both of the rotary propelling devices and the rotary brush; and a programming device controlling the transmission system such that, for preselected travel intervals, both rotary propelling devices are driven in the same direction to propel the body member along a linear path, and for other preselected time intervals, the rotary propelling devices are controlled such that the body member is propelled along a different path.
