You will need 39mm (1,5in) diameter hose attached to your pool outlet and into the nozzle and a bag to catch the leaves. Something like an orange (fruit) bag. V1 works very well and this is hopefully an improvement. The float before was also the funnel but as its printed getting it watertight without printing it fairly solid is a pain. This one can use a 600ml plastic cool drink bottle as a float. The arms connecting the pipe to the float has broken a few times and a bit of super glue works but I've changed them to 4mm shafts dowel sticks from a local hardware should do.Connected to the outlet pipe of your swimming pool uses a venturi effect to suck surface debris through the nozzle and into a bag.You will need 39mm (1,5in) diameter hose attached to your pool outlet and into the nozzle and a bag to catch the leaves.
