Maytronics Dolphin S300 Wifi Robotic Pool Cleaner
Maytronics Dolphin S300 Wifi Robotic Pool Cleaner
The Maytronics Dolphin S300 is a Wi-Fi connected robotic pool cleaner that scrubs and vacuums your entire inground pool — floor, walls, and waterline — in as little as one hour, with zero connections to your pool system and zero setup beyond plugging it into an outlet. Schedule it from your phone, check on it from anywhere, and come back to a clean pool. It's as simple as pool cleaning gets.
Drop it in the pool, plug in the power supply, and the S300 goes to work. No priming, no hose hookups, no booster pump, no connections to your filtration system whatsoever. Maytronics' PowerStream technology drives it across the pool floor, up the walls, through the coves, and along the waterline — scrubbing every surface clean while the dual fine and ultra-fine filter basket captures everything from large leaves down to fine particles. Schedule it from the MyDolphin Plus app, set a weekly cleaning timer, and your pool handles itself. When the cycle ends it parks and waits. Pull it out by the handle, pop the top-load filter, rinse it off, and put it on the caddy. Done in under two minutes.
Two Cleaning Modes — Simple and EffectiveStandard Clean
Full floor-to-waterline coverage — the S300 systematically navigates every surface of your pool in a single complete cycle. Best for your regular weekly clean or any time you want thorough top-to-bottom results. The go-to mode for most cleanings.
⏱ 2 Hour CycleQuick Clean
Fast, efficient coverage when you need results in a hurry. Before guests arrive, after a storm, or any time you need the pool presentable fast — Quick Clean delivers a solid pass at half the time of a standard cycle. Perfect for light maintenance between full cleans.
⚡ 1 Hour CyclePowerStream Mobility Technology
Maytronics' PowerStream system channels water discharge to generate continuous forward thrust — actively propelling the S300 across the pool floor and up the walls without losing suction contact. It doesn't just navigate the pool — it drives through it with consistent power from start to finish.
Fine + Ultra-Fine Top-Load Filter Kit
The S300 includes two filter sets — a fine filter for standard debris and an ultra-fine filter for capturing particles, pollen, and fine contaminants. The top-load basket access means you open the lid, lift the basket out, rinse with a hose, and drop it back in. No tools, no disassembly, 60 seconds.
Active Brush — Waterline Scrubbing
The S300's active brush spins at high speed, agitating and scrubbing algae, bacteria, and biofilm off pool walls and the waterline — where 90% of pool bacteria accumulates. Physical scrubbing combined with powerful suction means the S300 doesn't just collect debris, it cleans the surface itself.
60 ft Anti-Tangle Swivel Cable
The 60-foot patented anti-tangle swivel cable rotates freely through the S300's full range of motion — eliminating cord knots regardless of pool shape or how many direction changes the cycle involves. Reaches every corner of pools up to 50 feet without tangling or cable drag.
Plug & Play — No Setup Required
Unbox it, drop it in the pool, and plug the power supply into a standard outlet. Zero installation, zero connections to your pool system, zero priming. The S300 is ready to clean the moment the power supply is plugged in — no booster pump, no plumbing, nothing.
Less Than 15 Cents Per Clean
The S300's energy-efficient 24V DC motor system costs less than 15 cents in electricity per cleaning cycle — making it dramatically cheaper to operate than pressure-side cleaners that require a booster pump running in addition to your main pump. It pays for itself over time.
Anti-Obstacle Navigation
The S300's self-programming navigation scans your pool layout and charts efficient cleaning paths — navigating around pool stairs, the main drain, and fixed obstacles without stopping or getting stuck. Continuous cleaning runs uninterrupted from start to finish.
Saltwater Safe
The S300 is fully rated for saltwater pools. The motor and internal components are sealed and resistant to the corrosive effects of salt environments — so it works just as reliably in a saltwater pool as it does in a traditional chlorine pool, season after season.
Dolphin Universal Caddy Included
The S300 comes with the Dolphin Universal Caddy — a rolling storage and transport stand that holds the cleaner off the ground between uses and makes moving it from storage to the pool deck effortless. Keeps the cord organized and the unit protected when it's not in the water.
Weekly Timer
Program the S300 to clean automatically on a set weekly schedule from the app. Set it once and your pool cleans itself on the days you choose — no manual starts, no remembering to drop it in.
Delay Start
Schedule the S300 to start a cleaning cycle at a specific time later in the day — while you're at work, overnight, or any time that's most convenient. Set it in the app and walk away.
Spot Clean Mode
Take manual control of the S300 directly from the app and steer it to any specific area you want to target — a corner, the steps, or any spot that needs extra attention between regular cycles.
Cycle Selection
Choose Standard or Quick Clean mode from the app before each cycle — so you always have the right level of cleaning for the situation without touching the power supply.
Wi-Fi + Bluetooth
Connects via Wi-Fi for full remote control from anywhere. The app automatically falls back to Bluetooth if Wi-Fi signal is weak near your pool — so you're always connected regardless of your outdoor network conditions.
Remote Monitoring
Monitor the S300's status and cleaning progress from your phone. Receive alerts and maintenance reminders through the app so you always know when the cycle is running, complete, or needs attention.
