Depending on the pile height of your artificial grass, you will want to make sure your PerfectGroom is set to the appropriate height. If the height is set too high the perfect groom will have trouble cleaning up debris and combing the grass blades appropriately. On the other hand, if the height of the PerfectGroom is set too low the PerfectGroom can have trouble navigating through the artificial grass, infill may be shifted, and the overall performance of the PerfectGroom may be inhibited. It is important to note that the only time you would want to set your PerfectGroom height low would be to prepare for an infill regeneration.
