Like I said, I have two area rugs that are very difficult to clean and an abundance of shedding dogs and cats. The Miele SEB228, which is the W-W EBK360 with a different neck and Miele branding, leaves all the pet hair at the back of the stroke. You get a nice clean area in front of the nozzle, but when you push forward again all the pet hair is in a nice neat line at the back of the stroke. I can vacuum 90 degrees to that line of pet hair and all the darn thing does is move the hair around and leave it all in another nice neat line. The only way I can remove all of the hair is to scrape backwards off the edge of the rug and grab it later with a hard floor nozzle. Kludge! To be fair even our low hour and well cared for Avalir 2 struggles to clean these two rugs. It takes a few passes even with a good running Kirby to clean them. But power nozzles from Sebo, Lindhaus, Kenmore/Panasonic/Cen-Tec ( they are all made by the same company and share parts ) or even my funky Electrolux Ze3 have no problems on those rugs. Two passes, one up and one back and the hair is gone. A Miele SEB236 will eventually get the hair in six or seven passes but the $95 cost of a genuine Miele replacement brush roll makes me suck air between my teeth every time I use it.
I use a Kenmore Style Q bag, not a Panasonic brand bag, in my own MC-CG902 and it is spotless inside. The Kenmore brand bag has a thick mounting card. They are harder to install and can be hard to remove sometimes but they don't leak in my experience. Other brands do leak, sometimes a lot. So like Miele and Sebo, stick to the OEM bags and filters in your Kenmore.
Cen-Tec doesn't make power nozzles. They buy them from other manufacturers. The CT14 is exactly the same power nozzle sold with upteen Kenmore Premier and Whispertone series canister vacs, and several Panasonic models. They are identical to the original Whirlpool designed geared belt Powermate from 1981 ( also sold with the Whirlpool Power Clean series canisters 1982-87 ). There were three different upper housings but everything else is the same. Later on for the MC-CG973 Panasonic changed them from geared to poly v-belt drive and went with a modern style brush roll. They also introduced a quick disconnect neck for some models. That design continues mostly unchanged with the Titan T-7 power nozzle sold for central vacs and with their Titan T9200 canister. Cen-Tec was buying them from Panasonic and now sources their power nozzles from Suzhou Cleva Electric Appliance Co Ltd, same company that makes Kenmore vacuums and Titan canister vacuums and power nozzles. Late last year I refurbished an old 1982 vintage geared belt Kenmore Powermate with modern parts for a Titan T-7. New brush roll, poly v-belt and modern quiet motor with a ribbed pulley for the new belt. Everything dropped right in to the old Powermate base. All the mounting points are in their original positions. The upper cover is a little different and it has five ribs in the nozzle opening instead of only two, but otherwise it is the same sturdy reliable design that Whirlpool introduced in 1981. Now I have a quiet running Powermate for my old bomber Kenmore and it cleans better too.
