Dolphin Premium 40 review

The Dolphin Premium 40 (Product No. 99996241-PR4; UPC 810071220234) is listed by Maytronics as a corded, in-ground cleaner for pools up to 50 feet. Its exact U.S. product page specifies floor, wall and waterline coverage, MyDolphin Plus, a weekly timer, a Caddy, a main Fine Filter Kit and an additional Ultra-Fine Filter Kit in the box. This assessment compares those published fields; it is not a hands-on test or a promise that the robot will suit every pool.

Three named surfaces, but still an individual-pool fit check

The 99996241-PR4 technical table names floor, walls and waterline and lists a maximum pool length of 50 feet. It also gives rectangular, round, free-shape and kidney shape labels, but lists the pool classification as in-ground. Do not read the 50-foot number as a cord measurement: the product page does not state cable length, safe supply position or how much cord a complex deck, steps or obstacles may consume.

Surface coverage is a useful filter for a shortlist, not evidence that each cleaning cycle reaches every tile, slope, step, corner or waterline transition. The product page gives no depth range, pool-finish conditions or step/ledge specification. If any of those details define your pool, ask for current operating instructions that clearly apply to 99996241-PR4 and compare them with the actual pool geometry before choosing a seller. The exact page's in-ground-only entry is also a reason not to treat this as an above-ground alternative merely because a similar Premium model lists more than one pool class.

App and timer are not the same as remote steering

Maytronics names MyDolphin Plus and Wi-Fi, and the page lists a weekly timer. It does not describe the individual app functions in its technical table. The separate Automation Mode field is marked Yes but is not defined there; Remote Control is separately marked No. The Delay Feature is also No. Those distinctions matter if you want a particular remote action or a delay start: the model page supports app availability and a timer listing, but not those extra assumptions. Check the power-supply version, local Wi-Fi setup needs and the precise control functions against instructions for this exact product number.

The default cycle is listed as two hours, and the comparison row does not provide an alternate-duration list for this model. The table also says Enhanced Cleaning Cycles: No. I would not infer extra schedules, a user-selectable cycle length or a specific weekly sequence from the timer and app labels alone.

Filter kit and included equipment are unusually specific on the product page

The technical table lists Top Access, a main Fine Filter Kit and an additional Ultra-Fine Filter Kit under “Additional Filter in the Box.” That is stronger package evidence than an accessory tile, so the exact configuration is a plausible match when an included Ultra-Fine kit is essential. Still, the page does not give a particle-size rating, and a retailer may offer a changed bundle. Match the seller's listing and carton to 99996241-PR4 and confirm the included kit rather than relying on a similar model name. The page lists no full-filter indicator.

A Caddy is listed as included. The cleaner has two brushes, identified as Standard, and the page marks the brush active. Its listed suction figure is 4,000 gallons per hour; that is a manufacturer specification, not a measured pickup result. Maytronics publishes a robot weight of 18.566 pounds, net dimensions of 17.413 by 15.752 by 13.886 inches, and package dimensions of 23.7 by 19.4 by 19.0 inches. These help with storage and handling planning but are manufacturer figures, not measurements made for this review.

How it differs from the Premium 20

The separately researched Premium 20 (99996137-PR2) is listed for floor and walls up to 33 feet, not waterline cleaning; its page says no mobile application and no weekly timer, and its pool-classification field includes above-ground as well as in-ground. Premium 40 moves to a 50-foot pool maximum and adds a named waterline mode, MyDolphin Plus, a weekly timer, an included Caddy and the listed in-box Ultra-Fine kit. Both pages show a two-hour default and two-year warranty, but that overlap does not make their packages or instructions interchangeable. For a waterline or app requirement, the exact 40 model has the clearer listing; for above-ground use, its in-ground-only classification is a hard distinction to check.

A manual-link mismatch keeps operating details open

The product's support link opens a Maytronics portal headed Premium 40 and selected with Product No. 99996241-PR4. However, the English PDF linked from that portal identifies itself on the cover and inside as Classic 13 / Classic 13+, not Premium 40. That mismatch means I have not assigned the PDF's depth, water chemistry, cable placement, setup or maintenance instructions to this retail model. The separate product-page fields remain useful, but they do not replace a model-matched safety and care manual. The bounded check of a previously saved CPSC recall dataset also cannot establish current recall status; this assessment makes no safety-clearance claim.

Before buying, match the complete model number and UPC, verify the retailer's carton includes the stated filter kit and Caddy, ask for instructions that identify the exact 99996241-PR4 configuration, and confirm pool depth, finish, step shape, cable reach and supply placement for your installation. Primary references are the Maytronics U.S. Premium 40 product page, its exact-number support portal, and the page-linked product image. The image visibly says PREMIUM 40 and shows a blue cable; it supports identification and corded arrangement, not cable reach, package contents or in-pool performance.
