I do wonder how far Kirby can go with this design - I honestly thought the Sentria was the peak. "
Well Chris, there has actually been 2 modifications to the Mini emptor to significantly increase airflow between the G3 and late Sentria I models. There have also been 2 redesigns to the brushroll from G3 to Sentria as well.
I will however, agree with you that Kirby seems to have hit a brick wall with coming up with a completely new design that performs as well or better than the current G series Kirby's. I have seen patent drawings of a completely new Kirby that allows use of the hose and attachments without having to remove the floor nozzle which seemed to be permanently attached to the power plant / motor assembly. Not sure how the shampoo system would work with this design. Rumor has it that several working prototypes of this design have been manufactured but not put into production because the performance is less than that of the current G series machines. This shows that Kirby is trying to come up with a new design that performs at least <span style="font-size: 18pt;">as well <span style="font-size: 12pt;">as </span></span>the current Avalir.

"I disagree. The Heritage 2 and Legend 2 had a good balance between size, weight and sturdiness. Some of the older models like the DS80 were lovely and light too.
The G3 onwards is made heavier by the TechDrive. Bit of a catch 22, if it didn't have TechDrive, it would've need TechDrive."
Chris I disagree here also. I own a Heritage II Legend and a G3 and Sentria as well. I also have a bad back. Even though the H2 is lighter and rolls very easy when turned off, it does offer quite a bit of resistance due to suction of the nozzle to the carpet when turned on and lowered to the proper height for my carpet. It does hurt my back after vacuuming for just a couple of minutes . Although my G3 and Sentria weigh 8 lbs. more than my H2, I can vacuum my whole home with the G3 and have almost no back pain afterward. The G3 glides almost effortlessly over the carpet because the Tech Drive is overcoming the resistance caused by the suction seal of the nozzle to the carpet. I know this because when I turn the power off without raising the floor nozzle, the H2 and G3 roll so much easier.
