Dolphin Explorer E50

Brush And Suction. The Explorer E50 uses an active brush, so the brush is powered as the robot moves across the pool surface. Dolphin rates suction at 4,000 gph. Its cleaning coverage includes the floor, walls and waterline. Waterline scrubbing could be particularly useful if the band at the surface is where you regularly spend time with a hand brush.

Mapping And Tracks. Smart mapping guides the cleaner along a patterned path, and tracks carry it across the floor and up the walls. It supports floor inclines up to 15 degrees. That makes it suitable for a pool with a gradual slope within that limit, as well as a flat floor. Its supported layouts extend beyond rectangles to round and freeform pools. Dolphin's brochure calls its movement system PowerStream.

App Scheduling And Delayed Starts. Dolphin's brochure says the MyDolphin Plus app lets you set advanced cleaning schedules and delay the start of a run. Scheduling suits regular cleaning throughout the week, while a delayed start lets you put the robot in place before cleaning begins. These controls work through its Wi-Fi connection. You can also choose between cleaning cycles in the app. You can ask it to spot clean when a particular area needs attention between scheduled cycles.

Filter Basket And Access. Dolphin's product page describes an extra-large, multi-layer filter basket. The basket holds debris collected from the floor, walls and waterline, so you empty the same container after the cleaner has worked across those areas. The basket comes out through the top of the cleaner. You can reach it with the robot upright, without turning the tracked body over.

Cycle And Cable. The longest cycle runs 2.5 hours, and the app offers shorter ones. Because power comes from an outlet, repeat cleaning does not require a battery recharge between runs. The supplied cable measures 60 feet, and Dolphin's product page specifies an anti-tangling swivel. The swivel limits cable twisting.
