Hayward W3RC9740CUB SharkVac Automatic Robotic Pool Cleaner for In-Ground Pools - Self-Cleaning Pool Vacuum with Powerful Suction | Perfect for Concrete, Vinyl & Fiberglass Pools | Easy Setup & Energy Efficient Operation

This is a great pool cleaner. I add FilterBalls Green Minis to the debris compartments (about half full) and I do not need to run my sand filter. I run the SharkVac twice a day (7 PM and 5 AM on a timer, leaving the robot in the pool overnight). (I use a Remington SolaSkimmer to skim the surface.) This setup is not for everyone but I love it, mainly because it's quiet. It takes about 5-10 minutes per day to rinse the FilterBalls and SharkVac compartments with a hose. I don't take the filter cartridges out, I just take the compartment out and dump the FilterBalls onto the patio and rinse those and rinse the compartment off. If you want to try this, you have to get the FilterBalls Green Minis from Doheney's because I don't see them here. You could easily set this up to work off solar panels and you wouldn't even need an AC power source. Might not work in a large pool, mine is under 20,000 gallons. The SharkVac is nice because it has a good pump (3.5A power supply) that moves a lot of water and the handle doesn't block the discharge port. I was also able to use the SmartPool robot in the same way but those are not available at the moment (that cleaner will completely clean a green swamp without a filtration system). When you push the black button on the front of the SharkVac to open the debris compartment, push the center of the black button not the rim. I wish there was a solar skimmer about half the size of the Remington with a small biological sheet filter. I use BBB method, adding about a half bottle of liquid shock every evening around the perimeter of the pool.
