The best-value Max-Series™ robot, and the only one in its class with a weekly timer. Here is what Cayman owners say.
“The Cayman is AWESOME. The tracks work so much better than wheels or tires in other bots and the snap filter in the Cayman works flawless.”
Darcey L.Verified buyer, PoolBots
“The Cayman with Nano filters gets it all including the walls. Well worth the price. Wish I would have purchased it sooner.”
Jerry C.Brownstown, Michigan
“I'd been on the fence for buying a pool robot for a few years now and finally took the plunge. I wish I hadn't waited! My pool floor has literally never looked better.”
BruceVerified review, Maytronics.com
“Replaced an older model Dolphin with this one. Seems to be even better at cleaning. Love the cartridges, much easier to clean than the bag, and the top opening makes cleaning easier as well.”
Roger D.Pool Express
“Cleans our 26k salt water pool with ease, easy to clean filter. Easy to use, and cheaper than the same model at our local pool store.”
A. R.Verified buyer, PoolBots
“I should have purchased a long time ago. It cleans so nice, fast, it's absolutely awesome. Climbs the walls, scrubs the tiles and it's amazing.”
