I got it today and it is awesome. it attaches to the inlet jet not the skimmer basket and it creates a whirlpool effect. you can literally watch all the debris and pollen get sucked into this whirlpool and into the bag. I did try using it with my aquabot and that didn't go well. the aquabot knocked it off the wall and into the bottom of the pool. so no big deal. I'll take it off when using the aquabot. I love the Poolskim. I can't see any need to ever have to skim my pool manually.
