My recommendation would be the AquaDriver Helix 300. It’s designed for the Bubble King 300 and is a perfect fit and is truly an engineered neck cleaning system. It’s made in Germany and unlike any neck cleaner out there.

It’s made from CNC’d PVC just like the Bubble Kings lid and only adds 1” to the total height of the skimmer. Not only does it have a wiper for the neck but there is also one for the lid. When the wiper is rotating, it has a built in peristaltic type pump that draws water up from inside the body via a small silicone hose and sprays it onto the neck and lid for a wet wiping system. It uses a gear driven motor that spins the blade much faster than the others on the market so 15 seconds once a day is enough to prevent accumulation of grime without disturbing the slime coating. The blade is also angled so that grime is pulled up to the top of the neck where as all other neck cleaners have the blade straight vertical which smears the grime around allowing some to drop back into the skimmer. The underside of this cleaner where the blade attaches is conical shaped so that when foam rises towards the underside of the lid, it’s pushed outward towards the top of the neck. You can also get an optional collection cup washdown that, when supplied with a fresh water source, can be used to flood the collection cup with water to rinse it. You connect to the optional washdown ring via the included 1/4“ / 6mm john guest fitting and use RODI type tubing between the lid and the fresh water source.
