Buying guidance

Aquabot REVA or Dolphin Nautilus Titan: our take

Aquabot REVA and Dolphin Nautilus Titan 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 Nautilus Titan 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 REVA lists Gyroscope navigation. Dolphin Nautilus Titan lists 2 active brushes and CleverClean navigation.

Filtration and debris

Dolphin Nautilus Titan has documented included filtration—Basket and UltraFilter—while the other model's included media is not fully published. Dolphin Nautilus Titan has the clearer documented edge for fine silt, pollen and sand. Dolphin Nautilus Titan has the better documented path for bulky leaves and larger debris.

Controls and day-to-day ownership

Aquabot REVA provides smartphone control; Dolphin Nautilus Titan provides a weekly timer and smartphone control.

Price, warranty and the decision

Aquabot REVA is listed at $499 and Dolphin Nautilus Titan at $1,599; Aquabot REVA is $1,100 less. Aquabot REVA lists a 2-year warranty compared with 1 years for Dolphin Nautilus Titan. Aquabot REVA and Dolphin Nautilus Titan each have a specific fit, but neither is the Pool Express pick for this job. Our better alternative is Dolphin Quantum. Inground pools up to 50 ft that need floor, wall and waterline cleaning, with fine debris.
