Robotic Programming: Smart Z programming for Systematic Cleaning. Robotic Balance: Rights itself when inverted. Robotic Reverse: If RoboPhelps exits the water in a beach-entry pool, it will reverse and attempt to re-enter water. Robotic Injury Protection: The impeller automatically stops within 1 second if it is taken out of water while it is working. Robotic Self Preservation: The impeller stops working in case some large foreign matter is obstructing it. Robotic shut off: Shuts itself at the end of the cycle. Types of Pools: It cleans all types of pools: Above Ground and In-ground Residential Pools of all shapes, all types Tile (large & small), vinyl, Gunite, Fiberglass. Cleaning Performance: It cleans a Maximum Area 2800 Sq Ft in 2 hours and has a Filtering or Suction Rate 18000 Litres/Hour. Cleaning Features: You can select from 3 settings 0.5h ( Pool size less than 500 Sq ft) , 1h (Pool Size less than 1000 Sq ft) or (2h Pool Size greater than 1000 Sq ft). Method of Movement: Linear Jet Propulsion. Pool Cleaning Speed: Max 130?/h or 1400 Sq Ft /h. Ground Moving speed: 800 metres/hour or 44 ft/minute. Cleaning Roller Width: 34cm (Approximate 1.1 ft or 0.34 m). Floating Cable Standard Length: 2.5m , i.e 8.2 ft approximately. Maximum Climbing Height: 180 cm (Approx 6 ft or 1.8 m).
