Handle rotates up to 90 degrees on both sides and can be locked in position. In the normal position, the machine is swung to the right and left like a single-disc machine and achieves a high area performance. Locking the handle in the 90-degree position allows the operator to work in precise lanes, moving forward and backward as with a standard scrubber dryer for effective cleaning of large areas and precision cleaning close to walls and other fixed obstacles.
