The Dolphin T45 is a robust choice for inground pools up to 50 feet, featuring waterline scrubbing and Plug'n'Play setup. While it’s efficient on vertical surfaces, it lacks multiple filter options, a weekly timer, and app connectivity, which can be drawbacks for users looking for greater customization. The T45’s lightweight design and energy-efficient motors make it easy to handle, yet similar models with more comprehensive options may be available for a comparable price.

The T45 in detail
The Dolphin T45 is a corded robotic pool cleaner from Maytronics for in-ground and above-ground pools up to 50 ft long. It cleans the floor, climbs the walls and scrubs the waterline during its standard two-hour cycle. Active brushing loosens debris, while a swivel on the cable helps reduce tangles as it moves.
The extra-large filter basket lifts out from the top. Both a Fine Filter Kit and an Ultra-Fine Filter Kit are included. MyDolphin™ Plus app access, a weekly timer and an included caddy suit owners who want scheduled cleaning and convenient storage. The Dolphin T45, Maytronics model number 99996241-WINI, is sold exclusively through pool stores. Poolbots provides information and support resources for this model but does not sell it.
Who the T45 is for
The Dolphin T45 suits owners of in-ground or above-ground pools up to 50 ft long, including rectangular, round, free-form and kidney-shaped pools. It is a fit for owners who want the floor, walls and waterline scrubbed, along with app connectivity, a weekly timer and a caddy for moving and storing the robot.
Floor-to-waterline coverage
Cleans across the pool floor, up the walls and along the waterline in pools up to 50 ft long.
Active surface scrubbing
Two brushes, including an active brush, scrub pool surfaces as the robot cleans.

John Rodriguez of "Poolbots" recommended the Dolphin Sigma for my 20x40 Saltwater pool. I have to say, "John was correct...this thing is a beast!" I live in the SoCal desert and the Sigma picks up the fine dirt, sand and phosphate residue. John answered all of my questions. Shipping was quick! Semper Fi — USMC 1984-1992

I wish I would have converted my pressure side vac to an electric pool robot a long time ago. It cleans 10x better and completes my pool in 90 minutes.
