Dolphin T25 review

The Dolphin T25 (Product No. 99996137-WINF) is a corded residential cleaner whose U.S. listing documents floor-and-wall coverage and a pool-length ceiling of 33 feet. The same page lists a two-hour default cycle, a weekly timer and an additional Ultra-Fine Filter Kit in the box. It also says no waterline scrubbing and no mobile application. That combination makes the T25 a more capable surface-and-filter package than a floor-only cleaner on paper, but not an app-driven or waterline model.

What the 33-foot rating does—and does not—answer

Maytronics publishes a maximum pool length of 33 feet for this exact SKU. Treat that as a manufacturer screening limit, not a measurement of the floating cable, a guarantee for a particular pool route, or evidence that the power supply can be placed wherever convenient. The exact product-page image shows a T25 body and attached blue cable, supporting the corded classification. It does not show the cable's full length or a safe installation layout.

The U.S. table names the cleaning coverage as Floor and Walls and separately marks Waterline Scrubbing: No. A wall-climbing claim is not a waterline claim, and the listing does not give a step or sun-ledge boundary. It also identifies the product for both in-ground and above-ground pools and lists rectangular, round, free-shape and kidney shapes. Those broad labels do not settle whether a specific pool finish, transition, depth, slope or coping shape is supported. The selected mode and the model's actual instructions matter more than the category label.

A simple cycle with one scheduling feature

The default cycle is listed as two hours. Maytronics lists a weekly timer, but also lists Mobile Application: No, Delay Feature: No, Enhanced Cleaning Cycles: No and Remote Control: No. A weekly timer is a useful, distinct feature; it should not be expanded into phone setup, a delayed start, a menu of cycle durations or live steering. The specification table also says Automation Mode: Yes while the mobile-application field says No. The page does not define what that automation entry means for the T25, so it is kept separate from the app assessment rather than treated as a phone capability.

The page describes active scrubbing, a standard brush and one brush, and gives a suction-rate figure of 4,000 gallons per hour. Those are manufacturer descriptions and a published value—not independent measurements or a promise about debris pickup in a particular pool. The source provides no test results that would justify a performance ranking against another cleaner.

Filter configuration: read both lines

The exact U.S. page calls out an easy-access, top-load fine filtration basket and labels the filter type “Combine Filter Kit.” In the same table, “Additional Filter in the Box” is “Ultra-Fine Filter Kit.” Both statements matter: the extra filter kit is listed in the box for this configuration, but the page does not name a particle-size grade or prove what an unrelated retailer's carton contains. The T25's appearance beside separately numbered parts in the Add-On Accessories area does not convert those accessories into included contents or certify a fit for another model.

Top access is a design detail, not a cleaning-time claim. The T25 page does not provide a model-matched instruction result in Maytronics' exact-number manual portal: the linked 99996137-WINF query returns “No products were found matching your selection.” That gap means this assessment cannot fill in how to open the basket, rinse or dry it, select a mode, store the machine or check model-specific maintenance intervals. Do not borrow a T35 or T45 manual just because the names are close.

Handling, package and ownership checks

Maytronics lists a robot weight of 14.619 pounds, net dimensions of 17.189 by 15.776 by 10.386 inches, package dimensions of 22.2 by 17.6 by 12.8 inches and a two-year warranty. These are manufacturer-published specifications, not measurements made for this review. The T25 image and add-on tiles do not establish that a caddy or stand ships with every offer; its comparison-table cell for caddy or stand is blank. Confirm the precise Product No., all included items, warranty coverage and seller return terms before choosing a package.

Electrical setup is another open check, not an invitation to guess from the attached cable. Find the current T25 instructions and follow their power-supply placement, outlet, extension-cord and water-safety directions. Measure the real cable route separately from the 33-foot pool-size rating. If the T25 manual remains unavailable, ask the manufacturer or seller for the exact manual rather than using a sibling document.

Where the T25 sits among nearby names

The T15 is a different exact U.S. configuration listed for floor cleaning up to 30 feet. The T25 adds documented walls, a 33-foot maximum and an in-box Ultra-Fine Filter Kit, while still having no listed waterline scrubbing or app. The exact T35 and T45 listings are separate models with their own coverage and specifications; the T25's fields should not be extended from those siblings. If waterline cleaning is a hard requirement, this T25 page is a negative match even though the model is described as a wall cleaner.

Bottom line: the T25 merits consideration when the exact U.S. 33-foot limit, corded arrangement, floor-and-wall coverage and listed extra filter kit align with the pool and package. Its two-hour default and weekly timer do not make it app-controlled. Waterline, cable reach, step/depth limits, installation, manual-dependent care and caddy inclusion remain unresolved or explicitly absent, so verify those points rather than reading them into a model-family name.
