iGarden M1 Pro Max 100 Review: A Sports Car for Your Pool

Excellent battery longevity. Managed a perfect cleaning record, if you leave it in the water long enough. Delightful styling is conversation-worthy.

Basket is quite difficult to clean. Must be retrieved with a pole when finished. Confusing control panel. App does very little.

In an aquatic world dominated by robotic pool cleaners that mostly look identical, a company called iGarden has been that breath of fresh air you take after reaching the water’s surface.

The company’s pool cleaners have always featured designs that feel inspired more by high-end automobiles than underwater janitors, and with the new M1 series, its gear is sportier than ever. The question is whether dazzling looks translate to what really matters: The ability to effectively clean your pool.

Vroom Vroom

The new M1 series, introduced at CES 2026, evolves the design of last year’s K series, revising what was previously a sleek and streamlined look by adding what looks a bit like a bulbous cockpit component to the center of the device. You might expect this part of the robot to house cameras or other intelligence components, but that’s not the case: Rather, this is just a piece of the revamped debris basket, now designed to store up to 4.5 liters of detritus, a slight increase over the 4-liter basket available on the K series. The M1 is available in fire-engine red or black—the former being the far flashier choice. I, alas, was sent the latter as a test unit.

The 25-pound unit is designed with longevity in mind. The 12500 mAh battery on the M1 Pro Max 100 is massive, and an even bigger battery (14500 mAh, based on CES reports) will be available on the M1 Pro Max 125 when it ships. The 100’s battery will likely be enough for most users, though: iGarden says the model will provide up to 10 hours of run time in floor-only mode, enough for at least a week of daily operations.

You’ll spot another interesting design change by checking out the side profile of the M1 Pro, as the tread connecting each pair of wheels is no longer readily visible as it was on the K series. The tread is still there, but it’s been relocated to be concealed within the chassis except for a small stretch of it visible on the underside of the robot. The wheels of the M1 Pro are also now recessed within tight wheel wells, further enhancing the automotive look of the device.

Ready to Submerge

The iGarden M1 Pro Max 100 needs no real setup aside from a healthy charging session of about 5.5 hours (once you can dislodge the tight waterproof plug from the charging port) and configuration via the company’s mobile app. The app hasn’t changed much in the past year; it’s still useful only for setting basic operational parameters and installing firmware updates. It doesn’t even keep a historical log of cleanings. I expect most users won’t bother with it much after their initial unboxing and setup.

The complex control panel on the front of the M1 Pro Max also hasn’t changed from its last iteration. It remains obtuse and complicated, with four touch-sensitive buttons available in addition to the power button. The onboard controls allow you to set running time (1, 1.5, or 2 hours—or run-till-dead) and cleaning mode (floor only, wall/waterline, both floor and wall/waterline, or “full coverage”—which adds ledges and steps to the cycle). A turbo mode increases the robot’s speed (at the expense of some battery life), and the so-called AI timer is used to set repeated cleanings every 24, 48, or 72 hours, if you choose to leave the robot in the pool for the long-term. All of this is conveyed to the user via nonintuitive pictograms and adjacent dots; you’ll likely want to keep the manual handy to ensure you have everything set right.

To its credit, the app does make all of this easier to understand, and it also adds the ability to set longer running times of up to 10 hours in length. Connectivity is via both Bluetooth and 2.4GHz Wi-Fi, but as with most robots, it can only communicate with your phone while on land.

Note that when starting the robot, the flashing power button must be pressed after you’ve entered all your desired settings. If you forget to tap it—which is easy to do—the robot will sit silently on the bottom of the pool as if it were turned off entirely.

Slow and Steady

A note on test methodology: I test all pool robots with both organic and synthetic debris—using whatever leaves and dirt naturally accumulate in the pool, followed by testing with a known quantity of silk crafting leaves. The synthetic testing has the advantage of being endlessly repeatable, and it allows me to accurately quantify what portion of debris is collected by the robot. My pool is in-ground and L-shaped, measuring 12-by-36 feet on the long side, with an extra 6 by 6 feet on the short side, for a total of 468 square feet. Depth ranges from 4 to 7 feet. The surface is PebbleTec.

In the water, the M1 Pro Max is slow but methodical, but it’s aided by its ability to run for most of the day. In tests with both organic matter and synthetic leaves, it was effective at getting my pool 95 percent clean after about two hours, with scattered debris remaining in random locations on the floor. After a third hour, the M1 Pro Max invariably had all debris collected in my testing. That’s in part thanks to two 4K cameras mounted on the front of the robot; these actively scan for debris and can reroute the robot to trouble spots when it detects something—though this is difficult to observe when watching it work from the pool deck.

iGarden’s claims of providing 10 hours of running time in floor-only mode were accurate in my testing; however, I achieved only about seven hours of operation in the more power-intensive full coverage mode. That’s still plenty of juice for two or three full cleanings before a recharge is needed. Officially, iGarden specs the robot to clean pools of up to 1,274 square feet in size.

I was less enamored with the cleanup process after operations were complete, and not just because the robot must be retrieved with a pole instead of coming to the surface when done. The filter basket is plenty large, but it can only be accessed through a relatively small hatch. It’s tough to get all the debris out through this hatch by hosing it down, particularly since the shape of the basket includes a kind of shelf on the inside, where debris is both hard to reach and hard to see. A more open basket design or a larger hatch would be a huge help come cleanup time.

The basic box is designed with a fine-mesh filter on all sides, but this can be enhanced with a reusable second filter, included in the box, that snaps onto the outside of the basket. This filter has a finer mesh count than the filter on the basket itself, but despite that, most users probably won’t need it. I didn’t find it made much of a difference in my tests, but those facing problems with lots of fine-grained dirt and sand may find it helpful.

A Massive Price Cut

At $1,599, iGarden has aggressively priced this robot, knocking $1,000 off the price of last year’s K Pro 150 while keeping performance more or less the same. That makes this a much more enticing buy than the K series, and while it’s still a bit on the high side, it’s now roughly in line with a number of other top-shelf robots on the market. If you don’t mind getting a little wet when it comes time to retrieve and clean out the robot, it should be a very strong candidate for the job as your robotic pool guy.
