Choosing a Pool Cleaner: Which Solution Suits Your Pool and Dirt Profile

Sand on the floor, leaves after a windy day, or deposits on the steps: a suitable pool cleaner significantly reduces the manual maintenance effort. However, the choice should not be based solely on battery promises, app features, or eye-catching performance figures. What really matters are pool size, cleaning surfaces, filter structure, and actual handling.

Typical Buying Problems with Pool Cleaners

1. The stated runtime doesn't match your pool size

“Up to” 60, 120, or 180 minutes describes a maximum value under certain conditions. When climbing walls, dealing with heavier dirt, or using multiple cleaning modes, the actual runtime can differ. A small cordless pool cleaner may be sufficient for an above-ground pool, whereas a large in-ground pool will require several cleaning cycles.

So check the following:

  • Does the stated pool area or pool volume match your pool?
  • Does the runtime apply only to the floor, or also to walls and the waterline?
  • How long does a full charge take?
  • Is the battery replaceable or permanently built-in?

2. Floor cleaning is confused with full-surface cleaning

Not every pool robot is a pool wall cleaner or waterline cleaner. Models designed for flat, level floors work differently from devices that climb walls and brush the waterline. For an above-ground pool with a flat floor, a floor robot is often sufficient. An in-ground pool with steps, slopes, or different surfaces needs a suitably specified construction.

3. Filter fineness and filter volume are overlooked

A large filter basket can hold many leaves, but still needs regular emptying. A fine filter traps smaller particles like dust or sand, but can clog more quickly. So pay attention to filter fineness in micrometres, filter volume, and how the filter element is cleaned. A pool vacuum with an easily removable filter is often more practical in daily use than a hard-to-reach filter system.

The Most Important Selection Criteria

Pool type and cleaning surface

For small above-ground pools, children's pools, and whirlpools, a manual pool vacuum or electric pool vacuum is suitable. These devices are guided deliberately over the floor, steps, and corners. For larger areas, a cordless pool robot that autonomously covers the floor is a good option.

Take note of the manufacturer's specifications:

  • Pool cleaners for above-ground pools: often compact, lightweight, and designed for level floors
  • Pool cleaners for in-ground pools: depending on the model, suitable for floor, walls, and waterline
  • Pool cleaners for small pools: usually with lower filter capacity and shorter runtime
  • Automatic models with a hose: require a compatible filter pump and a suitable connection

Battery, charging time, and operation

A cordless pool cleaner avoids cables in the water and makes targeted cleaning easier. With an electric pool vacuum, the device should be fully submerged before the motor is switched on. Charging should only be done out of the water and with the supplied charger.

For daily use, the following details are also relevant:

  • Battery capacity in mAh
  • Runtime per cleaning cycle
  • Charging time
  • Weight when lifting out
  • Auto-parking or return to the pool edge
  • Spare battery, if provided by the manufacturer

A pool robot app control can enable cleaning modes, schedules, or status displays. However, it does not replace checking the filter and brushes.

Brushes, navigation, and water resistance

Brushes loosen stubborn deposits, while the suction transports the loosened dirt into the filter. For robots that clean walls and the waterline, the drive, sensors, and grip on the respective pool surface are crucial. Check whether the manufacturer approves the device for liners, tiles, concrete, or other surfaces.

The IPX8 rating describes protection against continuous submersion under specified conditions. It does not mean that the charger or charging station can go into the water. No people or pets should be in the pool during cleaning.

Care and Safe Use

After each use, rinse the filter chamber, filter element, and brushes with clean water. Allow the parts to dry completely and store the pool cleaner protected from direct sunlight. For battery-operated devices, the following applies:

  • Never bring the device into the water while it is charging.
  • Keep the charging port and charger dry.
  • Switch off the device before maintenance and filter cleaning.
  • Do not enter the pool while the robot is operating.
  • Do not continue using damaged housings, cables, or batteries.

Frequently Asked Questions about Pool Cleaners

Which pool cleaner is suitable for a small above-ground pool?

For small, shallow above-ground pools, a manual pool vacuum or a compact floor robot is often sufficient. What matters are a low weight, a suitable runtime, and the stated pool size. For walls and the waterline, the device must be explicitly approved.

How long does the battery of a pool robot last?

The lifespan depends on factors such as charge cycles, storage, water temperature, and maintenance. Follow the manufacturer's charging instructions, do not leave the robot in the water permanently, and store it dry. A replaceable battery can make long-term maintenance easier.

Does a cordless pool cleaner use a lot of electricity?

The power consumption depends on the battery capacity, charging time, and frequency of cleaning. A cordless model does not require a continuous power supply in the pool, but must be charged after use. With an automatic cleaner connected to the filter pump, the additional energy requirement depends on the existing pump and its operating time.
