Dolphin T35 review

The Dolphin T35 (Product No. 99996240-WIN, UPC 724131498139) is a corded U.S. residential cleaner listed for floor, walls and waterline in pools up to 50 ft. Maytronics also lists a two-hour default cycle, a weekly timer and an additional Ultra-Fine Filter Kit in the box. The same product table says Mobile Application: No. These are useful distinctions for shortlisting, but they are manufacturer-listed features—not test results or a promise that the robot will suit every pool.

Read the 50-foot figure as a pool limit

Maytronics' exact T35 page lists a maximum pool length of 50 ft. That number is a pool-size screen, not the length of the floating cable and not a guarantee that a given outlet position, power-supply location or cable route will work. The page's exact-linked image shows the T35 body and an attached blue cable, which helps verify the model and corded arrangement but says nothing about reach or safe placement.

The page lists the cleaner for both in-ground and above-ground pools and names rectangular, round, free-shape and kidney shapes. Those category labels do not settle a particular finish, coping, slope, step, ledge or depth. The T35 detail page does not give a step-depth qualification or a water-depth operating range. Measure the pool's actual layout and check exact-model instructions before treating the 50-ft ceiling as a fit guarantee.

Three-area coverage is not an all-pools promise

The U.S. listing says floor, walls and waterline, and separately marks Waterline Scrubbing: Yes. That makes T35 different from a floor-only or floor-and-wall listing. It still does not establish that every cleaning cycle follows the same route, that every waterline is reachable, or that a particular surface or transition is suitable. The page describes CleverClean navigation and active scrubbing, but supplies no independent test data for coverage consistency or debris pickup.

The technical table lists an active brush, two standard brushes and a suction-rate figure of 4,000 gallons per hour. These are published specifications, not measurements made for this review. They do not support a ranking against other models or an expectation of a certain cleaning result in an individual pool.

Default cycle, timer and control limits

Maytronics lists a two-hour default cycle, a weekly timer and no delay feature. The separate comparison table shows a dash for T35 under “Cycle Duration [H]”; the individual product specification still names the two-hour default. The listing does not document a T35 menu of selectable cycle lengths. It also says Mobile Application: No and Remote Control: No, so a timer should not be read as app setup or live steering.

One nearby comparison helps explain the boundary: the same T35 page shows MyDolphin Plus for the T45 and T55i, but not for T35, and lists selectable 1.5-, 2- and 2.5-hour durations for T55i only. It also identifies those as separate model numbers and configurations. Features from those sibling listings should not be transferred to T35. The T35 page does say Automation Mode: Yes, but does not explain that field; it remains an undefined manufacturer entry, not evidence of a T35 app feature.

Fine and Ultra-Fine are separate package lines

The exact product table labels the filter type “Fine Filter Kit” and separately lists an “Ultra-Fine Filter Kit” as an additional filter in the box. Its descriptive copy calls the basket extra-large, top-load and interchangeable. That combination may matter if filter choice is part of the purchase, but the page does not give the kit a particle-size grade. Confirm the exact Product No. and the seller's carton rather than assuming a third-party offer contains the same items.

The page also lists a two-year warranty, 18.412 lb robot weight, net dimensions of 17.413 by 15.752 by 13.886 inches and package dimensions of 22.1 by 17.7 by 12.4 inches. These are Maytronics specifications, not our measurements. The T35 comparison cell for “Caddy or Stand Included” is blank; caddy labels in the adjacent T55i and T45 columns do not prove that a T35 caddy ships in the package. Products shown separately under Add-On Accessories are not included-item or compatibility evidence.

Manual and installation checks remain open

The exact T35 product page links to a model-number manual selector, but the query for 99996240-WIN returned “No products were found matching your selection.” That failed lookup does not prove no applicable manual exists elsewhere; it does mean this assessment cannot responsibly supply T35-specific instructions for power placement, outlet distance, cable use, water depth, steps, pool finish, filter cleaning or storage. Do not fill those gaps with a T25, T45 or T55i manual just because the names are close. Find current T35 instructions or ask the manufacturer or seller before relying on model-specific setup guidance.

Bottom line: T35 is worth comparing when the exact U.S. listing's corded setup, three-area coverage, 50-ft pool-length rating, weekly timer and additional in-box Ultra-Fine kit align with the pool and package you are considering. The page does not list app support, a delay feature, an included caddy, cable reach or a T35 manual result. Verify the exact listing, seller carton, installation route and current instructions; the feature list alone cannot certify pool compatibility.
