Buying guidance

Dolphin Oasis Z5i or Dolphin T60: our take

Dolphin Oasis Z5i and Dolphin T60 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. Both are rated for pools up to 50 ft. Each cleans floor, walls, and waterline, so coverage alone does not separate them. Dolphin Oasis Z5i lists CleverClean navigation. Dolphin T60 lists 2 active brushes and CleverClean navigation.

Filtration and debris

Both models include Basket and UltraFilter. Both have documented fine-debris media, so basket capacity and ease of cleaning matter more than fine-particle capability.

Controls and day-to-day ownership

Both models provide a weekly timer and smartphone control. Both use continuous corded power. Dolphin Oasis Z5i is listed at 26.7 lb versus 24.3 lb for Dolphin T60; that 2.3999999999999986 lb difference matters when lifting the robot from the pool.

Price, warranty and the decision

Each lists a 3-year manufacturer warranty. Dolphin Oasis Z5i and Dolphin T60 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.

Dolphin Oasis Z5i vs Dolphin T60 specifications

Use pool fit first. Price and app control do not make up for a robot that cannot cover the length or surfaces you need cleaned.
