Which iGarden Pool Cleaner Is Right for Your Pool? K Pro vs K vs M1-AI vs KN vs K-AI vs KN-AI

What the K Series Is Built For

The K Series is sized for the most common residential pools. Rectangular, kidney-shaped, up to 6 × 12 m. It is built around features owners use weekly. 200% Turbo mode handles heavy debris after storms. AI Timer schedules cleaning at 24, 48, or 72-hour intervals. The 4 L basket and 180 μm filter cover most weekly debris loads without mid-cycle emptying. K36, K70, and K90 share the same body and the same cleaning capability. Only runtime and battery size change.

K Pro Series vs K Series: What's the Real Difference?

K Pro is a different ownership package, not just a longer-running K Series. Both share the same chassis, the same 4 L basket, the same 180 μm filter, and the same three-motor setup. K Pro then changes four things at once. The 14.1 Ah / 364.2 Wh battery enables 10 to 15-hour sessions versus the K Series's 5 to 9.4 Ah. An auto-docking system returns the unit to the waterline at cycle end. The body self-drains in five seconds and lifts easily, which actually matters when you pull a robot out of an 8 × 15 m pool every week. A nano-coating handles saltwater and UV exposure. K Pro is what you pay for when retrieval, drain time, and corrosion resistance start to matter as much as runtime.

M1-AI Series vs K Pro Series: What's the Real Difference?

M1-AI is the only iGarden series built around vision-based cleaning. It uses 4K dual-vision recognition to detect debris clusters, obstacles, and dirty zones in real time, then targets those areas instead of running a fixed pattern. Where K Pro maximizes session length on standard pools, M1-AI redirects that engineering effort into adaptive cleaning. The Dual-Force Flow system delivers stronger suction. The Dual-Grip Traction System combines four wheels with tank tracks for steeper walls and rougher floors. The Dual-Layer Filtration System replaces the single-layer 180 μm basket. Runtime tops out at 9 hours instead of 15, and a 21-day AI Timer keeps maintenance hands-off. The trade is clear. Less raw runtime, more cleaning intelligence.

KN Series vs K Series: What's the Real Difference?

KN keeps the cleaning fundamentals of the K Series. Same 180 μm filtration. Same three-motor system. Same full floor-walls-waterline coverage. It trades the touch-screen interface and 4 L basket for a smaller 3.2 L basket and an all-in-one control dial with four-color LED indicators. It runs caterpillar treads instead of standard wheels and ships with the 2026-upgraded Cross Pattern navigation, tuned for higher coverage on complex pool shapes. The KN line still supports 2.4 GHz Wi-Fi, Bluetooth, and the iGarden app. What you give up versus K Series is basket capacity, the touchscreen, AI Timer scheduling, and a year of warranty (2 years instead of 3). What you keep is the same 180 μm particle capture.

How Do I Choose Between iGarden Pool Cleaner Series?

Answer these four questions in order. One series will fall out at the end.

Is your pool freeform, or many obstacles? Choose M1-AI. Vision-based cleaning is the line's reason to exist, and no other iGarden series replicates it.

Is your pool larger than 6 × 12 m? Choose K Pro. K Series will still clean larger pools, but you will run into mid-cycle interruptions, and the K Pro retrieval and drain features matter more on bigger pools.

Is your pool standard-shaped and 6 × 12 m or smaller? Choose K Series. K70 covers most family pools, with K36 and K90 sitting on either side.

Is budget the primary constraint? Choose KN35 or KN55. Filtration stays at 180 μm, so the cleaning baseline is the same as K Series. The trade-off is basket size, control simplicity, and warranty length, not particle capture.

The next four sections handle model selection inside each series.

K Series: Which Model Should I Pick?

Inside the iGarden K Series, all three models share the same body, basket, filter, and cleaning modes. Only runtime and charge time change. Pick by how long your typical cleaning cycle needs to be.

K70 is the best K Series default for most family pools. K90 is worth the step up if you want shorter downtime between cycles, since it actually charges faster than K70 despite the larger battery. K36 is the right pick for compact pools where you rarely run more than two hours per cycle.

K Pro: Which Model Should I Pick?

iGarden K Pro 100 and K Pro 150 use the same 14.1 Ah battery, the same 4 L basket, the same 180 μm filter, the same auto-docking system, and the same nine-hour charge time. The difference between them is software-tuned cleaning duration, not hardware capability.

K Pro 100 is the right pick for most large-pool owners. K Pro 150 is worth the upgrade when your pool genuinely needs more than 10 hours per cycle, or when you would rather schedule one long pass every few days instead of two shorter ones.

M1-AI Series: Which Model Should I Pick?

M1-AI 55, M1-AI 70, and M1-AI 90 share the same 4K dual-vision system, the same Dual-Force Flow suction, the same Dual-Grip Traction System, the same 4.5 L basket with Dual-Layer Filtration, and the same 21-day AI Timer. Only runtime and price tier change between them.

Every iGarden M1-AI model carries the same vision and traction hardware, so stepping down to M1-AI 55 does not lose any cleaning intelligence. You only lose session length. M1-AI 70 is the most common pick. Step up to M1-AI 90 when your pool is at the upper end of the 8 × 15 m range or when obstacles slow each cleaning cycle.

KN Series: Which Model Should I Pick?

iGarden KN35 and KN55 share the same 3.2 L basket, the same 180 μm filtration, the same iGarden AI-Inverter motor system, and the same one-dial LED control. The choice maps directly to pool size and how long your cleaning cycles need to run.

KN35 is the right entry point. It charges fastest in the iGarden lineup and suits smaller pools where 3.5 hours of runtime is enough. KN55 is worth the step up if your pool is closer to 6 × 12 m, since the longer runtime and stronger peak suction matter at the top of the KN range. Neither model is right if your pool routinely loads heavy leaves, since the smaller basket fills faster than the K and K Pro lines.

FAQs

Do all iGarden pool cleaners use the same filter?

No. The K Pro, K Series, and KN Series all use 180 μm filtration with a single-layer basket. The M1-AI line uses a Dual-Layer Filtration System, which is part of what positions it for complex pools.

Can I use a K Series robot in a pool larger than 6 × 12 m?

It will still clean, but the K Series is rated up to 6 × 12 m and roughly 28,000 gallons. For pools above that size, the K Pro line or M1-AI line is the better fit, since they ship with longer runtime ceilings and a larger recommended pool footprint.

Is the M1-AI series worth it for a simple rectangular pool?

Usually no. M1-AI is built for irregular layouts, corner buildup, and obstacle-heavy pool floors. A clean rectangular shape rarely uses its AI vision to full effect, so a K Series or K Pro model often delivers the same end result for less.

How long does an iGarden cordless pool cleaner take to charge?

It depends on the model. K90 charges in about 3.5 hours, KN35 in 3 hours, and KN55 in 5 hours. K Pro 100 and K Pro 150 take around 9 hours because of their larger 364.2 Wh battery, which is also what enables their longer runtime.

Are iGarden pool cleaners cordless?

Yes. All four iGarden pool cleaner series in this comparison are cordless robotic pool cleaners. They run on rechargeable batteries, drop into the pool without a hose or floating cable, and self-dock when the cycle ends.
