Lienuis Cordless Pool Cleaner Robot for Above Ground Pools — 4400mAh Battery, 90-Min Runtime, Powerful Dual-Motor Suction

Designed for pool owners who want effortless upkeep, this cordless pool cleaner combines a 4400mAh rechargeable battery, DirtLock filtration technology, and smart sensors to remove leaves, sand, hair, and fine debris without dragging cords or hoses. Lightweight and easy to operate, it’s engineered to cover flat pool floors thoroughly and to park itself when its battery runs low, so retrieval is simple.

How long does the battery last and how quickly does it recharge?

The built-in 4400mAh battery provides up to 90 minutes of continuous cleaning on a single charge, sufficient for pools up to about 850 square feet. Recharge time depends on the charger and household outlet; expect a full charge within a few hours for regular use.

• Up to 90 minutes runtime per charge
• Rechargeable 4400mAh lithium battery
• Designed for routine cleaning cycles in one session
• Self-parks when battery is low for easy pickup

What types of debris and surfaces can it handle?

Lienuis’ dual-motor suction and advanced filters capture a wide range of debris—from large leaves to fine sand and human hair—without frequent clogs. It is optimized for flat-bottom surfaces commonly found in above-ground pools but also performs well on smoother in-ground floors.

• Removes leaves, twigs, hair, sand, and sediment
• High-efficiency filter basket traps fine particles
• DirtLock tech prevents debris escaping back into water
• Best on flat, even pool floors and gentle slopes

How does navigation and maintenance work?

Smart sensors guide the robot across the pool floor to maximize coverage while avoiding unnecessary bumps. When cleaning is finished or battery is low, the robot self-parks along the pool wall for quick retrieval; filters are designed for fast removal and rinsing.

• Intelligent sensors for systematic floor coverage
• Automatic parking near pool wall for pickup convenience
• Removable, large-capacity filter basket for easy emptying
• One-click start for simple operation

Is it easy to store and transport between pools?

The unit’s cordless design and compact footprint make it simple to move and store seasonally or between locations. Its lightweight build reduces lifting strain, and the lack of a trailing cord means fewer tangles or storage hassles.

• Cordless freedom: no tangled cables to manage
• Lightweight housing for easy lifting and storage
• Compact shape fits pool sheds and equipment closets
• Suitable for seasonal or multi-pool use
