Leaves and daily debris are two different cleaning problems that show up together. Leaves are bulky and seasonal. Daily debris is fine and constant. The cleaner that handles both well is one with a basket sized for leaf volume, a filter fine enough for pollen and sediment, and a runtime that fits routine maintenance rather than long single sessions. The iGarden K Series robotic pool cleaners are built around exactly that combination.
For most residential pools, the iGarden Pool Cleaner K70 is the balanced choice. The iGarden Pool Cleaner K36 fits smaller pools with lighter daily debris loads. The iGarden Pool Cleaner K90 fits properties with heavy fall leaf drop or pools that run on daily cycling. All three share the same basket, filter, brush system, and Turbo mode, so the choice is about how the pool gets used, not about cleaning capability.
Why the iGarden K Series Is Built for Leaves and Daily Debris
The K36, K70, and K90 share the same cleaning hardware. The features below are common to all three.

The 4L debris basket is the spec that matters most for leaf-heavy pools, more than runtime does. Leaves take up volume, not weight, and a small basket fills up after the first heavy week of fall drop. Once the basket is full, the cleaner keeps moving but stops collecting effectively, so the second half of every cycle runs at reduced pickup. The 4L capacity holds enough leaf material to get through a normal week of accumulation. Runtime extends how long a cleaner can keep moving, but once the basket is full, longer runtime stops adding cleaning value.
The 180-micrometer filter is what handles daily debris in the same cycle as leaves. Pollen, fine sand, hair, and the powdery sediment that settles in deep zones all pass through filters above 200 micrometers, which leaves the water visibly cloudy even after the leaves are gone. The 180-micrometer rating captures fine material without needing a separate finer-filter cycle for daily routines.
Turbo mode doubles suction for situations a default cycle cannot move fast enough. After a windstorm, a busy weekend, or a heavy pollen day, the pool collects more debris in 24 hours than a regular session is sized to clear. Turbo handles those events without forcing back-to-back cycles.
The dual scrubbing brush system covers floor, walls, and waterline in a single full-coverage cycle. For pools that collect leaves on the floor and pollen at the waterline, single-session coverage means both get handled in one pass.
Which K Series Model Fits Your Pool's Debris Pattern?
Each K Series model fits a specific kind of debris pattern.
iGarden K36 for Smaller Pools or Light Daily Debris
The iGarden Pool Cleaner K36 cordless robotic pool cleaner runs 3.6 hours in floor mode and 2.25 hours in full coverage. It is the entry K Series model and the right fit when the pool is on the smaller side and debris load is mostly daily rather than seasonal. For a pool that needs short, frequent sessions to keep up with pollen, fine sediment, and the occasional leaf, the K36 covers the job without paying for runtime that goes unused. It charges in about 4 hours, which fits the every-other-day rhythm most stable-condition pools run on.
iGarden K70 for Most Residential Pools
The iGarden Pool Cleaner K70 cordless robotic pool cleaner runs 7 hours in floor mode and 3.75 hours in full coverage. It fits the broadest range of residential pools and is the most balanced choice when the pool sees a mix of daily debris year-round and seasonal leaf events. The longer runtime over the K36 means a single cycle can handle a full-coverage pass plus enough margin for occasional debris events without needing a second cycle.
iGarden K90 for Heavy Leaf Drop or Daily Cycling
The iGarden Pool Cleaner K90 cordless robotic pool cleaner runs 9 hours in floor mode and 4.75 hours in full coverage. The runtime is part of why this model fits heavy-leaf properties, but the charging time is the bigger reason. The K90 charges in about 3.5 hours, faster than the K70's 5 hours and the K36's 4. For yards with continuous leaf drop through fall, or properties where the cleaner is running daily for several weeks at a stretch, faster recharge means less downtime between sessions. The K90 is the K Series model for the busiest cleaning seasons rather than for larger pools.
The K Series is sized for leaf load and daily debris, not for pool footprint. If your pool is large enough that a single cycle has to run 8 hours or more in full coverage to finish, the K Pro line is the better match, and the issue there is pool size rather than leaf volume. Heavy leaves on a regular residential pool stay within K Series territory.
Routine Adjustments for Heavy Leaf Periods
The same cleaner handles a stable summer pool and a peak fall pool, as long as the schedule changes with the season.
Move From 48-Hour Intervals to Daily Cycles
Under stable conditions, 48-hour AI Timer cycles are enough to keep ahead of daily debris. Once leaf drop starts in earnest, the basket fills faster than a 48-hour interval can accommodate, and debris settles into the floor texture between sessions. Switch to 24-hour cycling for the duration of peak leaf weeks, and return to 48-hour rhythm after the heaviest drop ends.
Empty the Basket After Every Cycle
Routine basket emptying once or twice a week works in stable conditions. In leaf season, the basket can fill in a single cycle, which means the second half of every cycle runs at reduced suction. Make basket emptying part of the post-cycle routine rather than something done on a weekly schedule. This is the change that does the most for cleaning quality during peak weeks, and it applies to all three K Series models equally.
Use Turbo Mode After Storm Events
A windstorm or rain event can drop more leaves and small debris in a few hours than a week of normal accumulation. A regular cycle on default settings struggles to handle that load in one pass. Turbo mode for the first cycle after the event clears the heavy material, and the next cycle can run on standard settings.
Skim the Surface for Large Pieces Manually
Robotic cleaners work on the floor, walls, and waterline, not the water surface. Large leaves floating on the surface eventually sink and settle into the basket, but they have a chance to clog the skimmer or stain the waterline before that. A two-minute manual skim with a leaf net before each cleaner cycle in peak season prevents both problems and reduces the load the cleaner has to handle.
FAQs
How can I tell if my cleaner is sized for my leaf load?
Two signs are reliable. The first is whether the basket fills before the cycle ends during peak leaf weeks. If you find debris in the basket but also fine material still on the floor after a complete cycle, the basket reached capacity and the second half of the cycle did not pick up effectively. The second is whether the cleaner consistently leaves whole leaves behind. If leaves are still on the floor after a session ran on Turbo mode with an empty starting basket, the suction or intake is not sized for the load.
What size debris basket do I need for leaves?
For leaf-heavy residential pools, a 4L basket is the practical baseline. Smaller baskets in the 2 to 3L range fill up partway through a cycle in fall, which leaves the second half running at reduced pickup. The 4L K Series basket holds a full week of normal residential leaf drop before needing to be emptied, and during peak fall weeks it holds enough to finish a full cycle before filling. Larger baskets in the 4.5L range exist on higher-end models built for complex pools, but the gain on leaf load specifically is small once basket size is past 4L.
How often should I run a robotic cleaner during fall?
Daily cycles are the right rhythm during peak leaf weeks. The cleaner needs to keep up with what falls in 24 hours, not 48. Once the heavy drop ends, return to 48-hour intervals for routine maintenance. The AI Timer on K Series models handles either schedule once it is set.
Will leaves clog the cleaner?
Whole leaves can clog intake channels on cleaners not built for bulky debris. The K Series intake and impeller are designed to move leaf material into the basket without jamming. The risk increases when the basket is full and material has nowhere to go, which is why basket emptying matters more during leaf season.
How often does the filter need cleaning during heavy debris periods?
The 180-micrometer filter sits inside the debris basket and gets rinsed at the same time the basket gets emptied. During leaf season, that means rinsing the filter at the end of every cycle. Under stable summer conditions, every two or three cycles is enough. Heavily loaded fine debris like pollen can reduce flow before the basket itself looks full, so a quick rinse before the cleaner shows performance drop is the right pattern during high-pollen weeks.
Can I run multiple back-to-back cycles after a heavy debris event?
Yes, with the basket emptied between cycles. The cleaner is built to run a full cycle, recharge, and run again, but it is not built to keep cleaning effectively with a full basket. After a major debris event, plan for emptying the basket, charging the cleaner if needed, and running a second cycle once the first has parked. Two cycles spaced this way clear most major events.
