S100 Cordless Robot Pool Cleaner - 130Min Runtime, Self-Parking

In this review of the S100 Cordless Robot Pool Cleaner the bottom line is clear: this unit is best for owners of above ground or flat-bottom pools who want a truly cordless, low-effort way to remove leaves, sand and algae. The single biggest reason to buy is the long 130 minute runtime from the built-in 5200mAh battery, which lets the robot cover up to 1100 sq.ft in a single session without messy hoses or tangled cords. Setup is simple: charge, long-press power, and drop it in the water for automatic cleaning and self-parking.

Key Features

• Cordless operation: Eliminates tangled cables and external pumps so setup is fast and cleaning is hassle-free for above ground pools.
• Double powerful motors: Twin motors create strong suction that picks up leaves, sand, gravel and floating algae from a flat pool floor.
• Long runtime: The 5200mAh battery supports about 130 minutes of continuous cleaning, enough to cover up to 1100 sq.ft per charge.
• Large filter basket: The roomy 180ml filter basket traps debris and rinses clean with a simple hose spray, reducing maintenance time.
• 18 slope gradeability and sensors: The robot climbs moderate obstacles, reverses on wall contact and avoids getting stuck in pool folds.
• Self-parking retrieval: When cleaning is finished or battery is low the unit docks itself next to the pool wall for easy removal.

Who It's For

The S100 is a practical choice for homeowners with above ground or flat-bottom pools who want a cordless, portable cleaner that requires minimal setup. It fits best where portability and cordless convenience are priorities, and where debris is typical household leaves, sand, and small gravel.

It is less suitable for pools with steep slopes, heavy vinyl liners with many folds, or specialty in-ground pools that need continuous suction via a dedicated pump. Users who need wall-to-waterline scrubbing or professional-grade suction for very heavy dirt may want a different model.

Pros & Cons

Pros

• True cordless design removes hose management and lets the cleaner operate independently.
• Long 130 minute runtime and coverage up to 1100 sq.ft per charge reduces the number of sessions needed.
• Robust filter basket and dual motors deliver noticeable pickup of leaves, sand and small debris.
• Self-parking and reversal sensors reduce retrieval hassle and the chance of getting stuck.

Cons

• Designed for flat-bottom pools, so performance may be limited on steep or heavily contoured floors.
• Because the unit is relatively small and light, partial draining of the pool is recommended before use in some setups.

Our Verdict

The S100 Cordless Robot Pool Cleaner is a sensible, value-focused option for above ground and flat-bottom pool owners who want an easy, cordless cleaner with strong suction and long runtime.

Those needing heavy-duty in-ground performance or aggressive wall scrubbing should consider a different class of cleaner.
