Mammotion's Spino S1 Pro robotic pool cleaner lifts itself out of the water

A robotic arm that sits at the edge of the pool retrieves the scrubber from the water and recharges its battery when cleaning is complete. Mammotion is best known for building robot lawn mowers, having only introduced its first robotic pool cleaner in July 2025, but it's looking to shake up the market with its second effort, now on display at CES. The Mammotion Spino S1 Pro promises nearly hands-off operation, thanks to a pool-side dock with a robotic arm that lifts the scrubber out of the water when its work is done. When you consider that pool robots can easily weigh 30 or 40 pounds when they're full of water, this innovation promises to make that task much easier for pool owners--especially older or less steady individuals--and it sounds like a potential major selling point.
