Pool robot and skimmer specifications from the Pool Robot Finder database.
The Betta SE Plus floats on your pool and skims leaves, pollen and insects off the surface. Compared with the Betta SE, it adds a wall adapter for cloudy spells and a shallower design for pools with shallow steps. Betta quotes more than 30 hours of skimming on a full charge.
The Dolphin Nautilus CC scrubs the floor and walls of pools up to 33 feet long, inground or above-ground, with a powered brush. It is one of the lighter wall-climbing Dolphins at 14.8 pounds. In return, it leaves out a timer, an app and waterline cleaning, so each two-hour cycle starts when you switch it on.
The Dolphin Nautilus CC Plus cleans the floor and walls of inground pools up to 40 feet long, and it adds Wi-Fi scheduling through Dolphin’s app, which the plain Nautilus CC does not have. It plugs into a power supply, so there is no battery to charge. Like the CC, it leaves the waterline to you.
