A bottom lid assembly helps form the lower closure and support area of a compatible robotic cleaner housing, and this Maytronics Dolphin version measures approximately 12-1/2 inches by 9-1/4 inches using the 99919116 reference. Bottom-lid components are important because they influence cleaner fit, closure, and internal component protection.

This assembly has practical value because a damaged or misaligned bottom lid can affect how securely the cleaner closes and how well surrounding parts remain supported during use. A properly selected Maytronics replacement helps restore original dimensions and contributes to a cleaner, more accurate repair.

This type of part is especially useful when the original lid is cracked, warped, or no longer fitting correctly after repeated service or impact. That helps bring the cleaner back into proper working condition without replacing the entire body assembly.

Installed in the proper application, this bottom lid assembly helps support cleaner housing integrity and more dependable overall operation.

  • Bottom lid assembly for compatible Maytronics Dolphin cleaner applications
  • Approximate dimensions of 12-1/2 inches by 9-1/4 inches
  • Helps support cleaner housing closure and component protection
  • Useful when replacing a cracked or warped bottom lid
  • Improves fit accuracy and service confidence
