Hey Guys,
....Turning the handle around basically adds the entire weight of the machine to the head of the driver. Some guys like to 'edge' their machines to try and scrub a stain a little bit more. The idea of flipping the Orbot over would apply an equal amount of head pressure over the carpet. Another advantage to flipping the Orbot over is if your sanding, scrubbing, or stripping VCT, tile, brick, grout, etc., etc.
To answer Greenie's Q, Yes the handle locks when it's folded down.
The handle grip bars are 1.75" in OD. This particular OD ended up being the popular choice as it gives the machine a more beefy feel to it than if it were a common bicycle grip of 1" or 1.25". Also the 2" cross beam that runs along the top is another good choice to grab on to the machine.
Jim are you maneuvering the Orbot in Australia mostly by the vertical grips or the 2" cross beam?
Thanks for the Q's guys....I'll do my best to get on the board more often.
