Cleaning Coverage and Navigation
The Explorer E40 and E50 both clean floors, walls, and waterline, but the E50 adds a waterline scrubber brush for more thorough cleaning along the waterline. The E50 also features Dual Drive steering for precise movement around obstacles, while the E40 relies on smart navigation. If your pool has tight corners or irregular shapes, the E50’s agile steering is a clear advantage.
Filtration System
Both models use a top-load filter basket for easy debris removal. The E40 comes with a standard filter, while the E50 offers an ultra-fine filter option for capturing smaller particles. If you struggle with fine debris like pollen or algae spores, the E50’s enhanced filtration will keep your water crystal clear. For more on filter options, see our best pool robot traction brush guide.
Connectivity and Control
Both the E40 and E50 are Wi-Fi connected and can be controlled via the Dolphin app. You can schedule cleanings, start or stop cycles, and choose cleaning modes from anywhere. The E50 adds an always-connected feature that keeps the robot ready for remote commands even when out of the water. The E40 requires you to have the robot powered on to connect.
Ease of Maintenance and Storage
The E50 includes a Universal Caddy for easy transport and storage, while the E40 does not. If you plan to move the cleaner between pool and garage, the caddy is a huge convenience. Both have a top-load filter basket that you can rinse with a garden hose. The E50 also offers an optional classic cover for added protection.

Final Thoughts
If you’re looking for a reliable workhorse that handles standard cleaning without breaking the bank, the Dolphin Explorer E40 is an excellent choice, offering smart navigation and Wi-Fi control at a more accessible price point. However, if you want the best possible cleaning performance with active scrubbing, a waterline brush, and the convenience of a caddy for storage, the Dolphin Explorer E50 justifies its premium with tangible upgrades that make pool maintenance effortless.
