Gemini PVC Commercial Robot Pool Vacuum. Optimized cleaning - Equipped with an infrared eye system to signal the brain of the cleaner to change direction as needed. Manufactured from high quality plastics, the new outer casings provide maximum protection against aggressive pool environments. The Gemini robotic pool cleaner runs off a low voltage power supply (29 volts DC), this maximizes safety while minimizing power usage. This robotic pool cleaner for public pools is fully automatic and completely self contained; no messy hoses or filter hook ups are necessary. Smart algorithm - The Gemini robotic pool cleaner uses the AquaSmart Gyro System to scan the pool and program itself to clean the entire pool floor in the least amount of time. It comes complete with an infrared eye that allows it to change direction as needed, a transport trolley, and a 120 ft or 150 ft premium floating cable. The Gemini pool cleaner has an internal timer that allows the start of the cleaning cycle to be delayed by 2, 3, 4 or 5 hours, the cleaner then runs for the programmed cleaning time of 3, 4, or 6 hours before automatically shutting off; this gives the pool owner the freedom to set and go.
