App is largely superfluous.Mammotion, primarily known for its robotic lawn mowers, is unique in the pool robot space as it produces just one model of water-bound cleaner: the Spino E1, which first arrived in the summer of 2025. Rather than dropping a new model in 2026, the Spino E1 has been upgraded with various software improvements this year, while keeping the same model ID. (Amazon listings note “2026 Upgrade,” but firmware updates should handle older stock, too.)
At $499 on sale, this is a comparatively low-cost robot, albeit one that does check off a healthy number of most-wanted features. I put it to work in my pool for a week to see where it stands—swims?—against the competition.
Never Mind the Looks, It’s Not a Toy
Photograph: Chris NullThe design of the Spino is unique and perhaps divisive, with its busy color scheme that suggests a child’s toy more than a piece of expensive home equipment. The dual-tread design and central brushes are fairly standard across most pool robots, but the unit feels slightly smaller in comparison to others. At 21 pounds, it’s not exactly a featherweight, but the generally tighter, more compact chassis does make it more maneuverable when getting it in and out of the water.
The unit features a 6,000-mAh battery, which is decidedly limited compared to the field. Charging is via a standard plug-in A/C adapter, via a charging port that is covered with a rubber stopper when the robot’s in the pool. I didn’t find this stopper all that effective at keeping water out of the charging port, as every time I removed the stopper after a run, I found considerable amounts of moisture inside. Nevertheless, this never seemed to impede the charging process or present any other difficulties.
The Spino E1 features a simple filter basket with a hinged lid. Its 2.8-liter capacity is small but commensurate with the overall size of the device and its battery capacity. In other words, this is a robot best deployed in smaller pools (though Mammotion questionably claims support for up to 1,600 square feet of cleaning coverage).

The Spino E1 fully charges in about three hours. The device includes four operating modes, all selectable via the single button on the robot's front panel, which also serves as the power button. The modes include Floor, Walls, All (floor, walls, and waterline), and an Eco mode that runs the robot in floor mode for 50 minutes, every other day (this can’t be changed)—good for about three runs in total.

ScreenshotSpino app via Chris NullThe robot uses Bluetooth to communicate with your phone and uses 2.4-GHz Wi-Fi to connect directly to your home network for over-the-air updates (but not real-time management). Onboarding requires connecting to a temporary network on the device and bridging it to your home network, a quick process that gave me no trouble during setup. Firmware updates will likely be available, but note you’ll need to check the Device Information menu for them. Mammotion didn’t proactively push or suggest any updates during my testing, and these over-the-air updates often required multiple attempts to install successfully.
The app is decidedly limited, allowing you to select from the standard four operating modes and make a few small additional adjustments, including configuring the maximum speed of the robot and opting into a couple of beta features. These include a “Turbo Cleaning” mode that increases the power of the suction at the expense of battery life, and an option to improve the way the unit cleans steps and platforms. (Why this feature isn’t always on is a mystery.)
Leaves Left Behind
Photograph: Chris NullThroughout my test runs, I saw fairly consistent performance results. The Spino E1 offers acceptable cleaning capabilities, though it’s far from perfect. With synthetic leaves, the unit averaged a cleanup rate of only about 80 percent, leaving behind a significant amount of material uncollected. This material wasn’t just isolated to corners and steps; it was scattered all around the pool. I also noticed the unit cleaned steps and platforms well, but it struggled heavily with obstacles, particularly at the waterline.
I saw similar results with organic debris, and the E1 struggled particularly with smaller particulate matter like dirt. On one run, I could best describe the pool as looking a bit like some of the debris had been smeared around on the pool floor instead of sucked up into the debris basket. All of this is unusual and suggests not that the unit has coverage issues, but rather that the device simply may be underpowered.
ScreenshotSpino app via Chris NullGood news: The Turbo Cleaning mode available through the app was visibly more effective and bizarrely did not impact battery life at all. The bad news is that this option, still in beta, has to be manually activated in the app before each run of the robot. Hopefully, Mammotion will simply make Turbo Mode the default soon.
When finished, the Spino E1 climbs the pool wall and waits by the waterline for collection—at least momentarily. The problem is that the robot doesn’t push a notification via the Mammotion app to alert you when a cleaning cycle is done, and since the robot has to run its propulsion jets to float, you only have a limited time (about 10 minutes) before the battery dies and the robot sinks. A hook is included in the box to aid with pole-based retrieval in this event.
While Mammotion claims a maximum running time of 3.5 hours, every test run I performed topped out at well under that, between 2.25 and 2.75 hours. Mammotion’s app logs each run, but only the absolute basics, largely limited to the date, time, and length of each session (all noted as a “Mowing Report” in the app).
Lastly, the Spino E1’s debris basket is easy to clean with a quick spray of a garden hose, though some debris can get trapped near the ridge where the basket connects with the robot’s pump. The few leaves trapped here are easy enough to fish out, however.
A Deal, But Not a Great Deal
At about $500 on sale, the Spino E1 is a relatively affordable robotic option, though you can find better equipment around this price, such as the Dreame Z1 Pro. With more effective default cleaning capabilities, the Spino E1 might make for a competitive option, but for now, there’s more work to be done. The last thing I want to do after pulling a robot out of my pool is have to reach for a pole and net to finish the job it couldn’t do.
