Buy Dolphin SigmaDolphin Sigma or Aquabot Elite: our take
Dolphin Sigma and Aquabot Elite 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. Dolphin Sigma lists 2 active brushes, SmartNav 3.0 with gyroscope navigation, and Triple commercial-grade DC motors. Aquabot Elite lists 3 active brushes and Intelligent navigation.
Filtration and debris
Dolphin Sigma includes Standard filter and NanoFilters; Aquabot Elite includes Standard filter. That gives Dolphin Sigma the clearer documented edge for fine silt, pollen and sand.
Controls and day-to-day ownership
Dolphin Sigma provides a weekly timer, smartphone control, and included remote control; Aquabot Elite provides a weekly timer. Dolphin Sigma uses a 55 ft corded cable with an anti-tangle swivel, while Aquabot Elite uses continuous corded power. Dolphin Sigma is listed at 24.6 lb versus 35 lb for Aquabot Elite; that 10.399999999999999 lb difference matters when lifting the robot from the pool.
