1. Choosing a Used Pool Robot

The market offers hundreds of models and just as many brands of pool robots. However, choosing a used pool cleaning robot is simpler than it seems: to identify the model best suited to your needs, you just need to ask yourself three fundamental questions.

  • What is the size of the pool?
  • What type of pool lining does it have?
  • What type of filter is needed?

By answering each of these questions, we can exclude unsuitable models and select the most efficient ones. Before analyzing the best available models, let’s answer these three questions to narrow down the choice.

If instead you want to immediately discover the best models for every type of pool, scroll directly to the Top 5 pool robots section or contact us: one of our consultants will explain the best solutions for your needs during a call.

Pool dimensions

Pool size is a fundamental aspect when choosing a pool cleaning robot, as it determines two essential elements.

  • The length of the robot cable, necessary to cover the entire pool surface without limitations.
  • The duration of the cleaning cycle, which must be suitable to ensure effective cleaning based on the pool size.

Below are the guidelines for choosing the ideal cable length according to the size of the pool:

  • Pools up to 12/15 meters: robot with an 18-meter cable
  • Pools up to 20 meters: robot with a 25-meter cable
  • Pools over 25 meters: robot with a 30-meter cable

Cleaning cycle duration

  • For pools up to 12/15 meters, a 2.0 - 3 hour cycle is sufficient.
  • For larger pools, cycles of at least 6 hours are recommended to ensure thorough cleaning.

How dirty is the pool?

Pools with high usage or heavy dirt accumulation require a robot with a longer cleaning cycle, to ensure repeated and effective coverage and keep the water consistently clear of frequent debris.

Pool Lining

The pool lining is the second fundamental aspect to consider when choosing a pool cleaning robot, as it determines the type of brushes the robot must use.

Brushes are essential to ensure:

  • The right traction on both the bottom and the walls, preventing the robot from slipping.
  • Effective debris collection, contributing to deeper cleaning.

Which brushes should you choose based on the pool lining?

Pools with PVC, liner, or polyester lining: PVC brushes, also combined with rings.

These brushes, called lamella brushes, provide good grip and are suitable for most pools.

Pools with particularly slippery surfaces such as tiles, mosaic, fiberglass, or painted concrete: sponge brushes.

These ensure optimal grip even on smooth or slippery surfaces, preventing the robot from losing traction.

If you decide to rely on us for the purchase of your used pool robot, we will recommend the most suitable model, with the ideal brushes for your pool lining.

Filter Type

The filter type is the final decisive factor when choosing a pool robot.

The used pool robots we offer are equipped with different types of filters, which directly affect dirt collection capacity and device maintenance.

The main types of filters available on the market are:

  • Bag filter
  • Cartridge filter
  • Basket filter

The efficiency of a filter depends on the size of the impurities it can retain, measured in microns. Robot filters can trap particles ranging from 30 microns up to 150 microns.

Bag filter (30-50 microns): maximum filtration capacity. It retains fine dust, algae, and micro-particles. It is ideal for those looking for ultra-fine filtration.

Cartridge filter (50-100-150 microns): a good balance between filtration and efficiency. It is easier to clean and suitable for pools with standard dirt levels.

Basket filter (50-100 microns): maximum practicality. It is easy to empty and suitable for common debris such as hair, insects, dirt, and sand.

Which filter should you choose?

  • Countryside area, pool with lots of fine dust or algae: bag filter.
  • Commercial pool with high attendance and professional requirements: bag filter.
  • Indoor or outdoor pool in areas with few debris or many insects: cartridge or basket filter.
