The cable construction is optimized to reduce shape memory and resist torsion. As the robot navigates intricate travel paths, the cable can lie smoothly within or beneath the water. Cable entanglement will hinder the robot’s mobility and disrupt cleaning operations.
The cable remains continuously exposed to various treatment substances including chlorine and bromine, solar ultraviolet radiation, and fluctuating temperatures. Selected raw materials should avoid degradation, embrittlement and surface cracking under such combined conditions.
Most pool robot cables are engineered to achieve neutral or mild positive buoyancy. This stops the cable from sinking and becoming trapped within the robot’s tracks or brushes. Meanwhile, underwater drag is lowered, saving power for battery-operated robots relying on cables for docking and charging, and boosting overall operational efficiency.
Fine-stranded tinned copper conductors are widely adopted. The tin coating delivers additional corrosion protection if moisture gradually penetrates the cable structure over extended usage periods.
High-grade PVC or Thermoplastic Elastomer (TPE) serves as the primary insulation and sheath material.
The waterproof junction where the cable connects to the robot housing is a vital design point. Reliable molded potting seals are generally applied to form a permanent watertight barrier and block water infiltration into the robot’s internal electronic assemblies.
Standard cable lengths range from 10 to 15 metres (30 to 50 feet). Such dimensions enable the robot to cover large swimming pools when powered via one single power supply point.
Ordinary power cords feature rigid construction, tend to sink underwater, and lack resistance to pool chemicals and UV exposure. When deployed for pool cleaning equipment, they suffer premature failure and are prone to knotting.
Though both varieties operate underwater, ROV cables are engineered to withstand deepwater pressure and sustain heavy mechanical loads. In contrast, pool cleaner cables focus on exceptional flexibility, anti-twist performance as well as chemical and UV resistance while maintaining cost competitiveness.
