I now have about 11 Protero PV18s. I originally would buy just the container and use the OEM Hustler Vac. The combination was great. Now Hustler changed their vac design, which I am not crazy for. So the last 2 units I have been using the Protero complete systems. So far they work great. The only problem I have is that, at times, a row of grass clippings get left behind. This will only happen with dry grass. Wet grass no problems, go figure.
They are slow in getting things done but, when I call, Bob is always there to answer my questins.
