Buy Dolphin SigmaAquabot Elite Pro or Dolphin Sigma: our take
Aquabot Elite Pro and Dolphin Sigma are compared on pool fit, cleaning reach, debris handling, controls and ownership details. The recommendation is based on the job the robot must do—not a simple feature count.
Pool fit and cleaning reach
Both robots are intended for inground pools. Dolphin Sigma has a published maximum pool length of 50 ft; the other model does not have a verified length in our source material. Each cleans floor, walls, and waterline, so coverage alone does not separate them. Aquabot Elite Pro lists AquaSmart navigation. Dolphin Sigma lists 2 active brushes, SmartNav 3.0 with gyroscope navigation, and Triple commercial-grade DC motors.
Filtration and debris
Aquabot Elite Pro includes Standard filter; Dolphin Sigma includes Standard filter and NanoFilters. Dolphin Sigma has the clearer documented edge for fine silt, pollen and sand.
Controls and day-to-day ownership
Aquabot Elite Pro provides smartphone control; Dolphin Sigma provides a weekly timer, smartphone control, and included remote control.

Dolphin Sigma includes filtration for sand, pollen and other fine debris. Dolphin Sigma adds gyroscope-assisted navigation.
