Dolphin Cayman review

The Dolphin Cayman (Product No. 99996135-SPL) is listed by Maytronics in the United States as a corded cleaner for floor-and-wall coverage in pools up to 40 feet. The same technical table says waterline scrubbing and mobile application are not available. This is a source-based assessment of that exact product number, not a poolside trial; a published pool-length ceiling is not proof that the supplied cable reaches every point in a particular installation.

Where the listing draws its coverage boundary

The page names floor and walls as the Cayman’s cleaning coverage, then separately marks Waterline Scrubbing: No. That distinction matters if the ring at the water surface is a must-clean area: a wall claim does not substitute for a waterline claim. The formal maximum is 40 feet. A pool at that exact length passes the published length screen, but the source does not give the cable length or where the power supply should sit. Measure the likely route and confirm the exact operating instructions before treating the rating as a practical fit.

Maytronics classifies the listing for both in-ground and above-ground pools and names rectangular, round, free-shape and kidney shapes. Those broad labels do not explain water depth, finish, slopes, benches or steps. The model-number manual portal currently returns no products for 99996135-SPL, so this assessment does not add unverified guidance about surface compatibility, ledges or safe setup. If any of those details decide the purchase, obtain instructions that name the exact SKU rather than relying on a different Dolphin’s manual.

A simple timer listing, not a complete schedule promise

The exact page lists a two-hour default cycle and Weekly Timer: Yes. It also marks Delay Feature: No, Mobile Application: No, Remote Control: No and Automation Mode: No. The source does not explain how the timer is programmed, what days it can select, or whether any other automation is available. Treat these as individual specification fields—not as evidence of phone scheduling, remote steering, or an unattended routine that suits every pool.

That distinction helps separate the Cayman from other corded models in the reviewed library. Some exact listings name an app and Wi-Fi; Cayman does not. If the important requirement is app-based scheduling or status, filter for models with that feature documented on their own page, then check the function and connection limits. A larger feature list on another Dolphin does not transfer to the Cayman.

Top-access Fine Filter Kit, with important unknowns

The listed filter is a Fine Filter Kit with top access. The page also lists an active Standard brush and a manufacturer suction-rate figure of 4,000 gallons per hour. That number is a specification, not a comparative test or a promise about how fast the Cayman will collect a particular mix of leaves and fine debris. The page does not state a particle-size grade or identify an additional filter as included, so an Ultra-Fine kit should not be assumed. Products shown in an add-on area are not automatically part of the cleaner’s carton.

There is no full-filter indicator listed. Owners should expect to inspect the basket rather than relying on a documented alert. The page names top access, which helps identify the design, but does not provide model-specific cleaning or maintenance instructions. Confirm that the exact seller package contains the advertised main filter and ask for compatible replacement part numbers if finer filtration is essential.

Published weight and package details

Maytronics lists the robot at 14.619 pounds, with net dimensions of about 17.189 by 15.776 by 10.386 inches; the package is listed at 22.1 by 17.7 by 12.4 inches. Those figures can help plan storage and lifting, but they are manufacturer specifications rather than measurements made for this review. The source page gives a two-year warranty. It does not establish that a caddy or stand is included, and a separately displayed accessory does not resolve that question.

The exact image linked from the product page shows a blue cable attached to a body marked CAYMAN. It confirms the model identity and corded arrangement, not how much cable is supplied or how the power unit should be positioned. The manual gap makes those practical checks especially important.

Who should keep it on a shortlist?

The Cayman is worth considering when a corded routine is acceptable, floor-and-wall coverage is enough, the pool is within the stated 40-foot limit, and a top-access Fine Filter Kit fits the maintenance plan. Its two-hour default and listed weekly timer may be relevant to someone who wants a repeatable routine, but the exact schedule controls are not described. It is a poor evidence-based match for an essential waterline, app, delay, or remote-control requirement because the product page explicitly says those are absent.

For comparison, the Dolphin Active 15 is also listed for floor and walls but has a shorter 33-foot maximum and an additional Ultra-Fine Filter Kit explicitly named in its box contents; Cayman has a 40-foot maximum, but its additional-filter field is not established. Those are meaningful package and rating differences—not evidence that either unit is better in use. Before ordering, verify Product No. 99996135-SPL, the seller’s included parts, warranty and return terms, and the exact-model manual, pool limits and power arrangement. The current manual selector response is no-result, so depth, finish, cable length, steps and installation requirements remain open rather than guessed.
