as you said, you have only been doing this a few months, maybe you where trying to speed up for the video, one thing i can tell you is, those extel poles are to flexy, and when you try to speed up, the brush head goes ahead of you at 50mph lol batterying the sides, just take it easy, slow down a little, or even ask someone here that lives localy if you could help them out for a day, and learn from a more experience person,
