the slot 221 the present invention is able to take advantage of the bernoulli principle which holds that velocity of water increases when water flows through a narrow constriction thus by constricting the flow of the water and debris into the basket 160 using the first tube slot 221 it has been observed that water and debris flows into the basket 160 at a higher rate than without the system 200 it has also been observed that offsetting the widthwise center 223 of the slot 221 from the widthwise center 136 of the skimmer opening 135 increases the flow of water and the debris into the basket 160 because the offset requires water and debris to travel around the first tube 210 like water drawing in a toilet before entering the slot 221 for example if the widthwise center 136 of the skimmer opening 135 is assigned the 6 o 39 clock position it has been observed that positioning the widthwise center 223 of the slot 221 at the 2 o 39 clock position is optimal in pools 110 that have a clockwise drain bias in the skimmer 100 see fig3 it would be deduced that positioning the slot 221 at the 10 o 39 clock position would be optimal in pools 100 that a have clockwise drain bias in the skimmer 100 preferably the widthwise center 223 of the slot 221 is offset from the widthwise center 136 of the skimmer opening 135 by at least about 30 degrees e g about 30 degrees to about 330 degrees u2014 i e between the 7 o 39 clock and 5 o 39 clock positions if the widthwise center 136 of the skimmer opening.
