Dolphin Proteus DX4 Automatic Robotic Pool Vacuum Cleaner, Wall Climbing, Waterline Scrubber Brush, Ideal for In-Ground Pool up to 50 FT in Length

The Dolphin Proteus DX3 is a robotic pool cleaner that works well for both fiberglass and vinyl in-ground pools up to 33ft. The normal filters on the robot can handle pet hair but might require some nominal maintenance. While the unit worked well for most customers, some noted concerns about the controller box failing after only a few months of use. There were also some complaints about the lack of instructions included with the control unit. Overall, the robot effectively cleaned the pool, and it was easy to start using and climbed walls, making it a good investment for pool owners.
