    We are going to work on it soon. Not sure it will be as graceful as you may have to switch it between functions to get everything.

    They go much deeper much faster than any other hoses. Just comparing the hose will show a significant difference. The TruBlu hoses have 1-3 microns of loss when the competitors often over 100.
