<p>A pool cleaner has a float and close proximity counterweight that together improve the applied torque to steer the pool cleaner, a body 13 has slots 33 diametrically opposed on the body 13 and these receive tangs 66 and 5 67 which depend from a circular body 68. The body 68 carries a circular guide-way 69 with a guide 70 travelling between opposite ends of the guide-way. Afloat 26 is connected to the guide by two pivot arms 71 and 72 which have openings at their ends so that they slide into position and are retained in place by snap in retainers 73 and 74. The guide 70 has a circular 10 shoulder 75 and at opposite ends of the guide has projections 76 and 77 such that the rail 78 of the guide-way is retained between the surface 75 and the inner surfaces 78 and 79 of the projections 76 and 77 with the rail against the surface 80. A corresponding structure is on the opposite side of the guide and this retains the rail 81 so that the guide slides around a circular path defined by 15 the rails 78 and 81. The guide 70 includes internal bores 82 and 83 at opposite ends and these are blind bores with an internal rib 84 so that stubs projecting from retainers 73 and 74 may snap fit into the bores 82 and 83 to retain the arms 71 and 72 in place and permit the pivoting action of the float 26 as illustrated in Figure 8 and Figure 9.
