Some of the features that make 4 wheel poolcleaner unique. The poolcleaner is a patented 4 wheel drive. What this means to you is that in combination with the patented tire treads, the cleaner has the power to overcome obstacles that normally stop other cleaners. Self adjusting turbine vanes. All the poolcleaner cleaners have the patented self-adjusting turbines, which maximizes the power from the water flow. This turbine is similar to a paddle wheel with blades that are adjustable. This feature allows the poolcleaner to still move at low suction and low pressure. In addition the folding vanes of the turbine allow for the easy passage of larger debris through the cleaner. The 4x suction poolcleaner has an internal programmed steering system, that causes the left wheel to periodically reverse, allowing the poolcleaner to turn and then move into another direction. For the 4x suction poolcleaner there are three different programmed turns ranging from 90 to 540 degrees. This feature allows the poolcleaner to cover not only the deep end, but also the shallow end. The poolcleaner has no problem with uneven surfaces or strange shapes. It won’t stick in a corner, or get hung up by a main drain. One look and you will see that the patented tire treads give the poolcleaner better climbing ability and obstacle maneuverability. The tires come with tread wear markers that show you when to replace your tires. The front tires of the poolcleaner have humps (raised treads) that allow the poolcleaner to overcome any reasonable obstacles such as the main drain and uneven surfaces. This makes the poolcleaner ideal for all pool surfaces and shapes. The poolcleaner has patented adjustable skirts that allow the cleaner to maintain optimal suction under the machine even when it encounters obstacles. When the poolcleaner encounters an obstacle one (or more) of the skirts will lift up (adjust) over the obstacle while maintaining suction under the cleaner. 30′ of hose included.
