M600
An app-controlled corded Dolphin that scrubs the floor, walls and waterline, with a caddy and pick-up mode. Nobody independent has tested it yet, so its cleaning is unproven beyond the maker's claims.
See the alternatives below, or switch market.
The short version
The M600 sits in Dolphin's M-line, the range sold through pool shops and dealers rather than online stores. It plugs into the mains, scrubs the floor, walls and waterline with two active brushes, and connects over Wi-Fi to the MyDolphin Plus app for scheduling and remote control. Maytronics rates it for pools up to 15 metres (50 feet in the US) and includes a caddy, a swivel on the cable and an ultra-fine filter.
The trade-off is price and evidence. It's a dealer-channel robot, and the only review we found comes from a site linked to a Dolphin dealer, which also calls it expensive next to Dolphin's online models.
Maytronics now lists a 2026 version (99996650). The review cited here tested the earlier US model (99996610).
Our take: Consider it if you buy through a local pool shop and want app control, waterline scrubbing and a longer warranty. Nobody independent has tested it, though. If you'd like a Dolphin with test results behind it, the Dolphin Premier also scrubs the waterline, though it has no app. If you'd rather skip the cable, the Aiper Scuba V3 is a cordless option that testers liked.
Where it sits in Dolphin’s range
What we know so far
Limited evidence No independent, finished hands-on review of this robot yet. What follows comes from the maker's specifications and early coverage, and says where something is untested.
We found no independent hands-on test of the M600. Robotic Reviews says it tested the earlier US model in its test pools, but the site is linked to a Dolphin dealer, so it doesn't count here. It reports full floor, wall and waterline coverage, an easy basket and an easy app, and calls it expensive next to Dolphin's online models. Everything else comes from the Maytronics (US) and Maytronics (Australia) listings.
Robotic Reviews, hands-on (tested on the M600, earlier US model (99996610-US); Site linked to a Dolphin dealer)
No independent test yet
Our search found dealer pages, refurbished-stock listings, one owner forum thread we couldn't open, and Robotic Reviews, a review site linked to a Dolphin dealer. None of that is an independent test, so the basics are unconfirmed: how well the waterline scrubbing works, how it copes with steps, and how the app behaves over a season. Treat the claims here as the maker's until someone tests it.
App, scheduler and pick-up mode
The M600 connects over Wi-Fi to the MyDolphin Plus app, with a weekly scheduler and several cleaning cycles, per Maytronics (US). Maytronics (Australia) lists modes including floor-only, fast and waterline-only. Pick-up mode parks it at the pool edge for easy removal. Robotic Reviews found the app easy to set up and use, and says Wi-Fi lets you control it from anywhere.
Filters and handling
It uses a top-loading multi-layer basket with an ultra-fine filter in the box and a full-filter warning, per Maytronics (US). Robotic Reviews found the basket easy to clean. It weighs 11.5kg, per Maytronics (Australia), heavier than Dolphin's entry models, so the included caddy is useful for moving it between the pool and storage. That weight is the maker's dry figure; it'll be heavier full of water.
Priced as a dealer model
Robotic Reviews recommends it but says store-only Dolphins are usually dearer than online models with similar features, and points to the Premier and Sigma. The three-year warranty, per Maytronics (Australia), is longer than the two years on Dolphin's cheaper online models. Compare what your local dealer offers, including the warranty terms, before you decide.
