Hi Guy's the sentria is called the G10,it's the same set up as the ultimateG,the high speed side of the motor works when the attachments are used,the heritage2 colors are being used,they changed the lower handle grip set up and the outer bag has a different zipper on it.The L.E.D. bulb is also a nice touch,the belt lifter is a little more user friendly.Just is correct the machine has been tweeked here and there,but has stayed the same mechanicaly,motor and fan unit have been around since the G3,the brush rollors are at a different angle.
A tip on kirbys for you guy's
Brush rollsg3,g4 are the same.
brush rolls g5,g6 are the same
ultimateG's and diamonds will interchange.
IT'S VERY IMPORTANT THAT THE CUSTOMER GETS THE BRUSH ROLL FOR THEIR MODEL.Try and interchange them and you will see what happens.IT'S NOT A GOOD THING.
Another tip is that the trannys dont interchange even though they look identical to each other.Please take my word on this.
