Quick answer
Separate interception of floating leaves from removal after they sink. Basket volume is useful evidence, but it is not a measured leaf-throughput test.

| Product | Research use case | Sourced features | Decision limit |
|---|---|---|---|
| Betta SE | Floating leaves | Filtration: 200 µm debris basket; Floor cleaning: No; surface skimming only; Power: Solar-powered cordless; built-in lithium battery | Betta SE targets surface debris; it cannot retrieve leaves already on the floor. |
| Polaris VRX iQ+ | Basket volume | Filtration: 5 L illuminated filter canister; Floor cleaning: Yes; Quick Clean and SMART modes; Power: Corded mains via control box; 70 ft floating cable | Polaris documents 5 L and Dreame 4.5 L. Volume alone does not confirm the largest leaf that can pass the intake. |
| Dreame Z1 Pro | Intake path | Filtration: 180 µm; 4.5 L basket; Floor cleaning: Yes; Power: Cordless; 9,600 mAh lithium-ion | Ask for allowed debris size and access to clear blocked paths; fine filtration is not a large-leaf claim. |
What to check before buying
| Decision factor | What to establish |
|---|---|
| Floating leaves | Betta SE targets surface debris; it cannot retrieve leaves already on the floor. |
| Basket volume | Polaris documents 5 L and Dreame 4.5 L. Volume alone does not confirm the largest leaf that can pass the intake. |
| Intake path | Ask for allowed debris size and access to clear blocked paths; fine filtration is not a large-leaf claim. |
| Emptying routine | Inspect after heavy leaf fall rather than assuming a rated runtime means the basket can hold a full session. |
Betta SE
Why it belongs here: For floating leaves, the US record documents Filtration: 200 µm debris basket; Floor cleaning: No; surface skimming only; Power: Solar-powered cordless; built-in lithium battery.
Who should consider it: Buyers assessing floating leaves who can meet the documented Betta SE installation and operating requirements.
Before choosing: Betta SE targets surface debris; it cannot retrieve leaves already on the floor.
Evidence limit: Betta SE is assessed for floating leaves using manufacturer documentation; this does not establish a comparative debris-pickup test result.

Full sourced specification recordHow we chose
Selection centres on floating leaves, basket volume, intake path, emptying routine. Separate interception of floating leaves from removal after they sink. Basket volume is useful evidence, but it is not a measured leaf-throughput test. This is source-based research, not a hands-on test or star-rated ranking.
Read the complete methodologyCommon questions
Is finer filtration better for large leaves?
Not by itself. Micron ratings describe filtration, while intake dimensions and basket access determine whether large debris is manageable.
Should I skim before cleaning the floor?
For floating leaf fall, surface skimming addresses a different stage of the problem; use a submerged cleaner for leaves that have sunk.
