Dolphin Explorer E25 manual and guides.

Short answer: Unwrap your Dolphin, place the power supply at least 12 ft (3.5 m) from the pool, connect the cable, let the robot sink, then turn it on.

Unpack your Dolphin and remove all plastic wrapping before setting it up.

1. Step 1Prepare your Dolphin and power supply

   • If your robot has white climbing rings, remove the plastic wrapping from those rings before the first cleaning cycle.
   • Position the power supply at least 12 ft (3.5 m) from the pool edge. Choose a shaded spot if possible. The power supply is splash-proof, not waterproof.
   • Caution: Using an extension cord is not recommended.
   • Measure the longest part of your pool to estimate how much blue cable you need. Unroll only enough cable for the robot to reach the entire pool. Keep the extra cable coiled outside the pool.
   • Connect the blue cable to the power supply. Match the connector plug to the notch on the power supply connection, then turn it clockwise until secure.
   • Plug the power supply into a power outlet, but leave it turned off for now.
   • Place your Dolphin in the water midway along the longest part of the pool.

2. Step 2Let your Dolphin sink

   Allow the robot to settle on the pool floor. If it has foam brushes or brushes with foam rings, press them into the water until they are fully soaked.

3. Step 3Start the cleaning cycle

   Press the ON/OFF button on the power supply to start your Dolphin.

Pool preparation and filter tips

Dolphin robots are designed for routine cleaning after you have completed the initial spring cleanup, started the pool filtration system, balanced the water chemistry, and removed major debris with a pool net.

Dolphin robots can be equipped with fine spring filters, ultra-fine filters, or both:

• Fine spring filters collect larger debris, including leaves, grass, and twigs. These filters are recommended for initial spring cleaning.
• Ultra-fine filters collect smaller particles, including sand and dust.

During and after cleaning

• Some models have adjustable handles that control the robot's speed while it cleans the waterline. Learn about Dolphin handles and floats.
• Never pull the robot by its cable while it is running.
• Your Dolphin shuts off automatically when the cleaning cycle finishes. If you stop it early, such as when the filter is full, turning it back on starts the cleaning cycle again from the beginning.

Find instructions for your model

For more information about your robot's features, look up its user manual. You will need your Dolphin model or serial number.

Short answer: After each cycle, remove your Dolphin from the pool and store it and its power supply away from direct sun, extreme temperatures and pool chemicals.

Image shown for illustration only.

After each cleaning cycle

Take your Dolphin out of the pool after every cleaning cycle. Store the robot and its power supply away from direct sunlight and excessive heat or cold to help prevent premature wear.

Keep the robot on a Dolphin caddy in a shaded spot. Coil the cable carefully so it does not kink.

Power supply placement

Use the power supply in a covered, shaded location that protects it from outdoor conditions, including rain, heat and cold.

Mount the power supply on the Dolphin caddy or set it on a raised surface away from the pool edge. Keep it at least 12 ft from the pool.

Offseason storage

When putting your Dolphin away for the season, store it on the caddy in a sheltered, well-ventilated area with a temperature between 41°F and 113°F.

Keep both the robot and power supply a reasonable distance from pool chemicals. Strong chemical fumes can cause corrosion over time.

Short answer: The plastic wrap protects the climbing rings during shipping and must be removed before the first cleaning cycle.

The plastic around the white foam climbing rings protects them during shipping. Small indentations can happen in transit, but they do not affect how the rings work.

Remove the plastic before running your Dolphin's first cleaning cycle.

1. Carefully cut off the plastic with scissors. Avoid cutting or damaging the foam rings. Leave the rings installed, they do not need to come off to remove the wrap.
2. Let the rings soak in water for at least 20-30 minutes. Once saturated, they will return to their original shape.

Short answer: Remove your Dolphin after each cycle, or leave it in for the full week if your model has a weekly timer or Eco Mode.

We recommend removing your Dolphin after every cleaning cycle so you can empty and wash its filters.

Between uses, keep the robot and power supply somewhere dry and out of direct sunlight. During operation, place the power supply in a shaded, covered spot away from water and direct sun.

Rinse your Dolphin regularly with clean tap water to help prevent buildup.

Using a weekly timer or Eco Mode

If your Dolphin has a weekly timer option or Eco Mode, it can stay in the pool for the full week. Clean the filter when the weekly cycle ends.

Safety and care reminders

• Keep your pool chemicals balanced when leaving the robot in the water for its weekly timer. Read more about water treatment and your Dolphin.
• For safety, always take the robot out before anyone swims.
• To confirm the length of your model's cleaning cycles, check your Dolphin user manual or your model's product page on Poolbots.

Short answer: Your Dolphin uses the timing-based CleverClean algorithm to navigate the pool, cleaning the floor and, if equipped, the walls and waterline.

Dolphin robots navigate with CleverClean, an algorithm that uses timing to guide movement around the pool.

Your robot is programmed to clean the pool floor. If it has a climbing feature, it also cleans the walls and/or waterline. Models with wall and waterline cleaning are programmed to clean those areas every 4-6 minutes.

When you turn your Dolphin on, it begins cleaning in the direction it is facing in the pool. Your pool filter pump can stay on while the robot cleans.

To help your Dolphin reach all areas, we recommend placing it in the middle of the pool, lengthwise.

For your model's cleaning modes and cycle length, check its user manual or its product page on Poolbots.

Short answer: Turn off and unplug the power supply, gently guide your Dolphin to the pool edge with the blue cable, then lift it by the handle and let it drain.

1. Switch off the power supply, then unplug the black cable from the electrical outlet.
2. Gently pull the blue floating cable to bring your Dolphin up to the pool edge.
3. Grasp the handle and start lifting the robot out. Let some water drain before lifting it completely out of the pool.

If you need help lifting the robot, a retrieval hook is available for purchase. It attaches to a standard pool pole to help you lift the robot safely out of the water. Ask Poolbots' pool experts about the hook by live chat or phone.

Do not yank the blue floating cable to pull your Dolphin out. Rough pulling can cause damage. Use the handle to lift the robot.

You can set the robot on the pool edge to let the remaining water drain.
