Dolphin Proteus DX3 review

This is a source-based assessment of the U.S. Dolphin Proteus DX3, Product No. 99996114-LSB, not a hands-on pool test. Its clearest fit is a corded routine that needs the floor and walls in a pool within Maytronics’ stated 33-foot maximum. The same page explicitly says Waterline Scrubbing: No, and it does not document an app or weekly timer.

A 33-foot pool rating with floor-and-wall coverage

Maytronics lists a maximum pool length of 33 ft and Cleaning Coverage: Floor and Walls. The exact U.S. page also names rectangular and round shapes and classifies the cleaner for in-ground and above-ground pools. Those are useful screening fields, not a promise that the machine will navigate every slope, corner, transition or surface. The 33-ft figure is a pool-length rating; it is not a measurement of the attached cable or a guarantee that the lead and power supply can be routed safely around a particular pool.

A buyer who needs a documented wall-cleaning option for a pool within that limit can keep the DX3 in the comparison set. The page does not give a minimum or maximum water depth, a surface-material list, or a qualified step or sun-ledge depth. Do not convert the general wall-climbing description into a specific step claim. Ask for instructions that identify the full 99996114-LSB number before treating an unusual shape or shallow feature as supported.

Wall cleaning is not waterline cleaning

The DX3’s exact table marks Waterline Scrubbing: No. That distinction matters because wall coverage alone does not answer a request for scrubbing along the waterline. If that area is essential, compare a configuration whose own U.S. listing names it, rather than assuming a wall-climbing product reaches the same zones.

Maytronics’ comparison on the DX3 page makes the model boundary concrete. It lists the separate Proteus DX4 and DX5i for up to 50 ft, with floor, walls and waterline coverage, while the DX3 is listed at 33 ft for floor and walls. The same comparison names MyDolphin Plus for the DX5i; it does not list mobile-app support for the DX3. These are distinct model numbers, not extra modes or upgrades to the DX3. The comparison table is a useful difference check, but it does not resolve cable length or the missing model-matched operating manual.

A simple listed cycle, without a documented app routine

The manufacturer’s technical attributes give the DX3 a two-hour default cycle. They mark Weekly Timer, Delay Feature, Mobile Application, Remote Control, Automation Mode and Anti Tangling Swivel as No. The comparison table leaves Cycle Duration blank, so the two-hour default should not be expanded into a claim about selectable durations. CleverClean navigation language on the page also does not imply phone control, an automatic schedule or a cable-swivel feature.

For a household comfortable with a manually started cleaner, those limits may be acceptable. They are a poor fit if the plan depends on remote status, recurring scheduled starts, delay, or an anti-tangle swivel. The page lists one active standard brush and a 4,000-gallon-per-hour suction-rate figure; those are manufacturer specifications, not independent performance tests. They cannot predict debris pickup or wall contact in a particular pool.

Top-access Fine Filter Kit; package details still need checking

The DX3 page names a Fine Filter Kit with top access. That supports a basket-style removal routine, but it supplies no micron rating. The product comparison shows a dash for “Additional Filter in the Box,” so an included extra Ultra-Fine kit is not established. Ultra-Fine baskets, panels and other filter accessories displayed lower on the page are in a separate Add-On Accessories section; their appearance does not establish inclusion or compatibility with every retail package.

Maytronics lists the robot at 14.796 lb, with net dimensions of 17.193 by 15.776 by 10.335 in and package dimensions of 22.1 by 17.7 by 12.4 in. These are published specifications, not my measurements. They can help frame a storage or lifting question, but do not show how the unit will feel when wet or what a dealer’s carton contains. The comparison field for Caddy or Stand Included is blank, so this assessment does not count a caddy as supplied. A two-year warranty is listed; check the exact seller, registration and service terms for the offer you are considering.

Exact U.S. identity and an unresolved manual route

Use the complete Product No. 99996114-LSB when checking a listing. The exact Maytronics U.S. product page identifies the DX3 and gives the matching technical table. Its own linked manual route, queried with that full number, returns “No products were found matching your selection.” I therefore do not import depth, safety, chemistry, setup, cable-routing or maintenance instructions from another Dolphin model or regional suffix. The attached cable is visible in the exact product image, but the image does not reveal its length or the approved position of the power supply.

Who should keep it on the shortlist?

The Proteus DX3 is a reasonable research candidate when a corded cleaner with listed floor-and-wall coverage is the goal, the pool fits within the stated 33-ft ceiling, and app control, weekly scheduling, waterline cleaning and an included Ultra-Fine kit are not requirements. It should not be shortlisted for essential waterline work, an app-dependent routine or a pool over 33 ft on the strength of this evidence. Before purchase, verify the full U.S. model number, the actual package and caddy status, obtain the matching manual, and check pool depth, surface, steps, chemistry, power-supply placement and cable route. This assessment does not claim ownership, use, testing, current price or stock, customer experience, or a comprehensive recall clearance.

Primary references: Maytronics’ exact U.S. Proteus DX3 product page, its Product No. 99996114-LSB manual route, which currently returns no product, and the manufacturer image linked from the exact page. The image visibly identifies the Proteus DX3 and shows a cable attached; it is not evidence of reach, package contents or cleaning performance.
