Dolphin Skimmi 300 (9997003-US) review

The Dolphin Skimmi 300 is a robotic pool skimmer, not a bottom-cleaning robot. Maytronics identifies U.S. Product No. 9997003-US and lists its cleaning coverage as the water surface. That distinction is the first fit question: if the main task is settled debris on the floor, submerged wall brushing, or scrubbing a tile line, this model does not replace a cleaner documented for those surfaces. It is better assessed as a separate floating-debris routine that can complement another pool-cleaning method.

Where the Skimmi 300 belongs in a pool routine

The exact U.S. product page describes a solar-powered cordless skimmer that collects surface debris and lists rectangular, round, free-form and kidney-shaped pools. The linked user manual likewise describes a surface skimmer and separates its operating modes: Eco for scheduled surface coverage, Edge-free to spend less time at the perimeter, Leaves Capture to prioritize larger floating debris, and Edge mode, which the manual marks as Skimmi 300 only. “Edge” should not be read as a submerged wall-scrubbing mode; the formal product table still calls the cleaning coverage “Water Surface.” Owners who also need floor or submerged-wall cleaning should plan for a second tool or a different robot rather than treating these modes as interchangeable.

Length guidance is not fully consistent

The exact 9997003-US technical table and Maytronics’ U.S. family listing show a 65-foot pool-size figure. A Maytronics U.S. FAQ, however, describes Skimmi use outdoors up to 60 feet. Because the lower value is meaningful when deciding whether one skimmer covers a pool, this library uses 60 feet as the conservative finder limit until the manufacturer clarifies the exact model guidance. A pool longer than that should not be counted as a documented fit on the strength of this assessment alone. These are pool-length claims, not a cord measurement: the in-pool operating arrangement is cordless.

Solar power still has a charging routine

The official 200/300 manual describes a 2.45-Ah lithium-ion battery that can recharge from the solar panel while the unit is in the pool. Its Eco settings offer 20-, 45- and 90-minute sessions, selected around available sun and expected debris load; the product table separately lists a 45-minute default cycle. Those are manufacturer settings, not a measured runtime guarantee. The manual also describes an external wall charger for low-sun conditions, and Maytronics’ FAQ says a Skimmi 300 includes one. Check that the exact seller’s 9997003-US package contains the expected charger, especially if buying a regional or third-party listing. The charger is for indoor use; the manual specifies a GFCI-protected supply in the United States and Canada and instructs users to close the charging seal before returning the robot to water.

Bluetooth app features are local, not a Wi-Fi promise

The exact product page lists Bluetooth app control. The support route linked from that page identifies the Skimmi 300 and links the English shared Skimmi 200/300 manual. It documents Maytronics One pairing over Bluetooth, status information, mode selection and Manual Drive. This supports an app-control match, but not Wi-Fi or internet-based control; neither is documented for this SKU. Manual Drive is useful to consider as a control feature, not proof that a phone can communicate with the robot from anywhere around the property. The manual distinguishes a few features by version, including the 300-only Edge mode, so its family-level instructions still need to be read with the exact model number in mind.

Filter care and use limits need attention

The manual describes removing the filter tray and rinsing both sides with low-pressure water before debris dries. It also recommends gentle solar-panel cleaning; abrasive scrubbing can scratch the panel. Neither the product table nor linked manual gives a micron rating, basket volume or a clear additional-filter package specification. Treat the filter as a maintenance item whose grade is not established here, rather than assuming an ultra-fine kit is included.

The shared manual lists water temperatures of 41–104°F, a maximum salt concentration of 6,000 ppm and IPX7 protection. It cautions against deliberately pushing the robot underwater, using high-pressure spray or swimming while it is in the pool. Its lithium-ion battery is not user-replaceable. These practical limits matter more than a general “all pool types” headline: check pool chemistry and temperature, follow the exact instructions, and plan for battery service through the manufacturer rather than opening the unit.

Who should shortlist this exact configuration?

The 9997003-US can suit an outdoor-pool owner who wants an automated surface-skimming role, can use solar charging with an indoor charger available when conditions are poor, and is comfortable with Bluetooth app setup. The listed robot weight is 8.952 lb, and Maytronics lists a three-year warranty; neither value says how manageable retrieval will feel for a particular person or how a claim will be handled by a specific seller. Confirm the exact number, warranty terms and supplied charger with the seller.

This assessment uses Maytronics’ product page, linked manual, family page and FAQ; no hands-on operation, ownership, cleaning test, runtime measurement or customer-experience review was performed. The official sources also conflict on 60- versus 65-foot pool guidance, and the exact filter grade remains unknown. For a pool with a strict length boundary, low sun, complicated edges or an essential floor/wall task, resolve those questions before choosing the Skimmi 300. It is a specialized surface-skimming candidate, not a universal pool-cleaner substitute.
