Buying guidance

Dolphin T2000 or Dolphin T25: our take

Dolphin T2000 and Dolphin T25 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 and above-ground pools. Dolphin T2000 is rated for pools up to 40 ft; Dolphin T25 is rated up to 33 ft. Dolphin T2000 cleans floor, walls, and waterline; Dolphin T25 cleans floor and walls. Dolphin T2000 lists 2 active brushes and CleverClean navigation. Dolphin T25 lists 1 active brush.

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

Dolphin T2000 provides a weekly timer and smartphone control; Dolphin T25 provides a weekly timer and power-supply controls. Dolphin T2000 uses continuous corded power, while Dolphin T25 uses a 50 ft corded cable. Dolphin T2000 is listed at 17.9 lb versus 15 lb for Dolphin T25; that 2.8999999999999986 lb difference matters when lifting the robot from the pool.

Price, warranty and the decision

Dolphin T2000 is listed at $1,199 and Dolphin T25 at $849; Dolphin T25 is $350 less. Each lists a 2-year manufacturer warranty. Dolphin T2000 and Dolphin T25 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.
