Frequently Asked Questions
What can I do with the MyDolphin Plus app?
The MyDolphin Plus app lets you schedule weekly cleanings, select cycle duration options, and trigger a spot clean from your smartphone. You can manage the cleaner remotely from anywhere with a Wi-Fi connection.
Does the S300 clean walls and the waterline?
Yes. The S300 climbs pool walls and scrubs the waterline in addition to cleaning the floor — delivering complete pool coverage in every cycle without manual brushing.
How do I access and clean the filter?
The S300 features a top-access XL filter basket. After removing the cleaner from the pool, open the top lid, lift out the basket, and rinse it clean with a garden hose. No tools required.
Does it require a booster pump?
No. The S300 is a self-contained robotic cleaner with its own motor and pump. It plugs directly into a standard outlet and operates completely independently from your pool's filtration system.
What is the caddy used for?
The included standard caddy is designed for easy transport and poolside storage of the S300. After each cleaning cycle, lift the cleaner out, set it on the caddy, and roll it to your storage area — keeping the cable organized and the unit off the ground.
