Kirby G Series Differences

[eurekastar]

I know the basic design of the Kirby G series has remained in tact. But what changed from model to model (other than cosmetic changes)? I know with the G6, a new bag boot design was introduced to improve airflow. Somewhere along the way (Ultimate G?) a new brushroll with stiffer bristles was used. Disposable bags improved too and later Sentrias were given a new bag adapter. What else? Also, were there changes within any particular model (like the new bag adapter on the Sentria)? Thanks!

I know with the G5 Kirby switched to Torx screws to make it harder to service....

There was a 2 speed switch added to the Ultimate G Diamond Edition. LED Lights were added to the Sentria.

Kirby "G" model Kirby differences...

That list is long. Here are a few I remember (not necessarily in order):

Belt lifters, cord hook (strengthened), handle pivot assy, slide assy, torx screws as Karl said (mid-model G4 actually), belts, rug plates, power switch, brushrolls, fans, bag top adapter (on the G4 also), cords-anchoring, transmission, motor (DE), bag top cover (G4 since), headlight shape for safety (removed sharp/pointiness), cord cover (mid-model G3), etc.

I hope this is helpful.

Cheers & hagn all,

Bill
