Maytronics Dolphin S400 Wifi Robotic Pool Cleaner
Maytronics Dolphin S400 Wifi Robotic Pool Cleaner
The Maytronics Dolphin S400 is a Wi-Fi connected robotic pool cleaner that handles every surface of your inground pool — floor, walls, coves, and waterline — while you control it from your phone. Three cleaning modes, three cycle time options, a multi-layer top-load filter, PowerStream mobility technology, and a fully featured app that keeps you connected from anywhere. Set it and forget it, or take control on demand. Either way, your pool gets clean.
The S400 is Maytronics' most connected mid-tier robotic cleaner — and it shows in every detail. Drop it in, open the app, choose your mode, and the Dolphin handles the rest. PowerStream technology delivers continuous, powerful thrust that drives the unit across the floor, up the walls, through the coves, and along the waterline without losing momentum or suction contact. The multi-layer top-load filter catches everything from large leaves down to ultra-fine particles — bacteria, pollen, and fine debris that most pool filters miss entirely. When the cycle ends, activate Retrieve Me mode and it climbs to the waterline on its own. No stooping, no struggling. Lift it out, pop the top-load filter, rinse it off, and put it away. The whole post-clean process takes under two minutes.
Three Cleaning Modes — Pick Your CycleStandard Clean
Full coverage from floor to waterline — the Dolphin S400 systematically covers every surface of your pool in a single thorough cycle. Best for your regular weekly clean or any time you want a complete top-to-bottom result.
⏱ 2 Hour CycleQuick Clean
Fast floor-focused coverage for when you need the pool clean in a hurry. Before a party, after a storm, or any time the floor needs attention but the walls are fine — Quick Clean delivers an efficient pass in the shortest cycle time available.
⚡ 1.5 Hour CycleEnhanced Clean
The most thorough cycle the S400 offers — extended coverage with more passes on the floor and walls for pools that deal with heavier debris loads, algae buildup, or seasonal opening conditions. When the standard clean isn't enough, this is.
⏱ 2.5 Hour CyclePowerStream Mobility Technology
Maytronics' PowerStream technology channels water discharge to generate continuous forward thrust — actively propelling the S400 across the pool floor and up the walls with consistent power. It doesn't just navigate the pool; it drives through it, maintaining suction contact with every surface at all times.
Multi-Layer Top-Load Filter
The S400's multi-layer filtration system captures debris at multiple sizes in a single pass — large leaves and debris in the outer layer, fine particles and ultra-fine contaminants in the inner layers. The top-load design means you open the lid, lift the basket out, rinse it off, and drop it back in. No tools, no disassembly, 60 seconds.
Filter Indicator Light
The power supply features a filter indicator light that tells you when the filter basket is full and needs cleaning — so you're never guessing whether to rinse it before the next cycle. One of the most practical features on the S400 that most pool owners immediately appreciate.
Active Brushing — Eliminates Algae & Bacteria
The S400's active brush system doesn't just agitate the surface — it actively scrubs down algae colonies and bacteria biofilm that cling to pool walls and floors. Combined with the multi-layer filter capturing what gets dislodged, the S400 delivers genuinely hygienic pool cleaning, not just debris removal.
Retrieve Me Mode
Activate Retrieve Me from the app or the power supply and the S400 navigates to the pool wall and rises to the waterline for easy retrieval. Water rapidly evacuates from the unit as it climbs — so when it reaches the surface it weighs almost nothing. No reaching down, no lifting from the pool floor.
Anti-Obstacle System with Motor Protection
The S400's continuous cleaning anti-obstacle system detects obstructions — pool stairs, main drains, toys, and fixtures — and navigates around them without stopping or getting stuck. Motor protection engages automatically if the unit is impeded, preventing damage and keeping the cycle running uninterrupted.
Patented Swivel Cable
The patented swivel cable rotates freely as the S400 changes direction — eliminating the cord knots and cable drag that interrupt cleaning cycles. The swivel joint handles the full range of the S400's motion without tangling regardless of pool shape or how many direction changes the cycle involves.
Plug & Play — No Setup Required
Unbox the S400, drop it in the pool, and plug the power supply into a standard GFI-protected outlet. That's the entire setup. No connections to your pool system, no booster pump, no priming, no hose hookups. It's ready to clean the moment the power supply is plugged in.
Saltwater Safe — IP68 Motor Protection
The S400 is fully rated for saltwater pools and carries an IP68 motor protection rating — meaning the motor is completely sealed against water ingress. Designed for continuous submersion in chlorine and salt environments without degradation to the motor or internal components.
Weekly Scheduling
Set your S400 to clean automatically on a weekly schedule from the app. Choose your days, pick your mode, and the Dolphin handles it — no manual start required. Your pool cleans itself on a schedule you set once.
Delay Start Mode
Schedule the S400 to start a cleaning cycle at a specific time later in the day — so it runs while you're at work, overnight, or any time it's most convenient. Set it in the app and walk away.
Manual Drive Mode
Take direct control of the S400 from your phone using the app's manual drive feature — steer it to any specific area of the pool you want to target, whether it's a corner, the steps, or a spot that needs extra attention.
Push Notifications & Alerts
Receive push notifications when the cleaning cycle completes, when the filter needs cleaning, and for maintenance reminders and tips. The app keeps you informed without requiring you to check on the cleaner.
Wi-Fi + Bluetooth Fallback
The S400 connects via Wi-Fi for full remote control from anywhere. If Wi-Fi isn't available near your pool, the app automatically falls back to Bluetooth connectivity — so you're never without control even in outdoor areas with weak Wi-Fi signal.
Cycle Selector
Choose Standard, Quick Clean, or Enhanced mode directly from the app before each cycle — so you can pick the right level of cleaning for the situation without touching the power supply unit.
