Introduction to Dolphin Robotic Pool Cleaners
Dolphin robotic pool cleaners are among the most popular and reliable automated devices used for maintaining clean swimming pools across the globe, including in the United States. Known for their efficiency, durability, and cost-effectiveness, these devices have become an essential part of many pool owner’s maintenance routines. However, like any sophisticated equipment, Dolphin pool cleaners can encounter issues—one of the most common being the device floating uncontrollably on the water surface instead of operating underwater as intended. Understanding the underlying causes of this problem and knowing how to troubleshoot it can save you time, money, and frustration.

5 Common Causes Why Dolphin Pool Cleaners Float
1. Loose or Damaged Hose Connection
The most frequent reason for a Dolphin pool cleaner to float is a compromised hose connection. If the hose is loose or has cracks, it allows air to enter the system. Since air is less dense than water, it causes the cleaner to lose its underwater positioning and start floating on the surface. To resolve this, first inspect the hose connection points and tighten any loose fittings. If you notice any cracks, tears, or broken sections, replacing the hose is necessary. Ensure the replacement hose matches the original specifications for proper fit and function. Click here to purchase compatible replacement hoses for your Dolphin pool cleaner.
2. Damaged O-rings or Climbing Rings
O-rings or climbing rings serve as sealing components in Dolphin pool cleaners, preventing water leaks and air ingress. When these rings become worn out, cracked, or damaged, they compromise the seal, allowing air to enter and causing the device to float. Regular inspection and timely replacement of damaged O-rings are essential. You can find suitable replacement rings easily online or at local hardware stores.

3. Water Inside the Float Head
If your Dolphin cleaner is equipped with float heads, the presence of water inside these components can alter its buoyancy, leading to floating. To diagnose this, remove the float head and gently shake it; if you hear or feel water inside, it indicates a need for replacement. Proper sealing and regular maintenance can prevent water from seeping into float heads, ensuring the cleaner stays submerged and functions optimally.
4. Incorrect Adjustment of Thrust Jet Nozzle
The thrust jet nozzle controls the movement and direction of the robotic cleaner. An improper or misaligned nozzle can disrupt its balance, causing it to float or drift uncontrollably. If your Dolphin cleaner is floating, check the nozzle’s position and alignment according to the manufacturer’s instructions. Adjust it carefully to ensure the device maintains the correct orientation underwater. When in doubt, refer to the user manual for precise guidance on nozzle adjustments.
5. Broken or Malfunctioning Back Valve
The back valve plays a crucial role in debris collection and movement regulation within the cleaner. A damaged or broken back valve can cause air leaks, leading to buoyancy issues. Always inspect the back valve regularly, especially if you notice inconsistent cleaning performance or floating behavior. If damage is detected, it is advisable to replace the back valve. For best results, consult a professional or follow detailed repair procedures provided by the manufacturer.
6 Practical Steps to Fix a Floating Dolphin Pool Cleaner
Resolving floating issues in your Dolphin cleaner is straightforward with a systematic approach. Follow these six simple steps to troubleshoot and fix the problem efficiently:
- Step 1: Turn off and unplug your Dolphin robotic pool cleaner. Carefully remove it from the pool along with its hoses for inspection.
- Step 2: Connect a garden hose to the cleaner’s hose and run water through it. This helps detect any leaks or cracks in the hose or fittings.
- Step 3: If leaks or damaged sections are identified, replace the defective parts promptly. Replacement parts are available online or at local stores. Click here to browse replacement parts for your Dolphin cleaner.
- Step 4: Reassemble the cleaner and place it back into the pool. Observe whether it still floats or remains submerged as intended.
- Step 5: Check the float head for water inside. Gently shake it to listen for water sounds. If water is present, replacing the float head is recommended.
- Step 6: Inspect the O-rings and seals. Replace any that are cracked or broken to ensure proper sealing and prevent air ingress.
Frequently Asked Questions (FAQs)
Are Dolphin Pool Cleaners Reliable?
Yes, Dolphin pool cleaners are generally considered reliable and durable when properly maintained. Regular cleaning, timely replacement of worn parts, and adherence to manufacturer instructions can extend their lifespan. Proper maintenance ensures they perform efficiently, reducing the likelihood of floating issues or other malfunctions.
What Prevents Pool Cleaners from Floating?
Pool cleaners are designed with internal weights, float heads, and adjustable nozzles to maintain stability underwater. When these internal components are intact and correctly positioned, they prevent the device from floating. However, damage or wear to these parts, along with air leaks through hoses or seals, can cause the cleaner to lose its buoyancy and float on the water surface. Routine inspections and maintenance help prevent such issues and ensure optimal operation.
