I love canister vacuums!!
Despite my love of canister vacuum cleaners, I have found that Filter Queen power nozzles tend not to be very powerful. Yes, they have a chevron dual brush agitator but the bristles are soft, the motors tend to be a little weak and they don't have agitation edge to edge.
Your Kennmore power nozzle that you're describing sounds like a Cen-Tec CT14DX. That is the standard power nozzle that Kenmore used on most of its canisters at that time. Pictured below is the power nozzle with different coloring and different logos but otherwise same outer shell design as the model I think you have. These power heads do a decent job cleaning and have decent motors. Therefore my thinking is that there is either a clog in the wands or power nozzle or your agitator may be shot. A few things you can do: 1. Check the height setting on the power head. Most likely it should be set to XLow or low. Unless your carpet pile is a shag, style loose weave, then on most denser pile carpets the CenTec nozzles work best set on Xlow. Also make sure the height adjuster is working well, wheels should sink all the way in and raise out accordingly as you depress pedal. 2. Check your wands and hose, ensure that any suction relief valves are closed so you're not releasing suction anywhere. 3. With power nozzle motor off, but Central vac suction on, check the suction at the power nozzle. Try running it on bare floor and see that its sucking up dirt easily. 4. Check bristles on power nozzle and check agitator in general. You can swipe a credit card across base of nozzle and see how much bristle is extending beyond the base plate. Also I would disassemble the unit and check belt and agitator. It should be a geared belt but they need to be replaced as well, about every year. Your agitator should turn very smoothly with out getting stuck anywhere, rubbing etc., and be clean. See how all of that turns out. You can purchase a new brush roll for these. Either online or local vac shop, I would go to one of those over Sears. While new brush strips are still available for that model, I would recommend the new agitator. CenTec changed everything over. I personally think that the newer agitator runs smoother, quieter and cleans better. The newer brush roll replacements for these power heads is a different design now. It's a wooden brush roll with 2 rows of chevron style white bristles. Let me/ us know how all of these turns out. Also at sometime, we would love to see an actual picture of what you have.

Agitator shot
Here is the blue power nozzle above, but it has the newer style agitator in it. Notice the chevron shape. This also also has a few upgrades over the model made in 1987.
Your 1987 model would have a completely flat base plate front on the bottom. The one in this pic, has ridges carved out to allow better airflow. Also there are more nozzle support bars in this one. They add support to the base while also further preventing area rugs from being sucked in. Your 1987 model would only have 2 support bars on the far side in addition to the belt cover. Of course your agitator is different you have the black agitator with 2 rows of white colored replacable, straight brush strips and green beater bar.

You're Welcome!!
A central vac should have significantly more suction and airflow over your Filter Queen canister vac or for that matter any normal upright and canister. Curious how the suction feels on your hand and how it does picking up dirt through bare floor brush, and/or power nozzle with agitator motor turned off?
Sounds like your agitator brushes are ok. If you have the Kenmore power nozzle that I'm thinking of, you do not need to replace belt every 2 months. It should have a cogged "geared" belt design. These have little tension on the motor and they maintain their grip with the cogged design. Generally they wear well up until anything jams in the brush roll such as sucking up a sock, area rug, etc. Then the belts can stretch. Often on a stretched cog belt you'll hear loud vibration and thumping, thats the gears on belt slipping over each other on motor pulley rather than riding with the pulley. That said, once or twice a year should work fine for that belt, save yourself some money, those cogged belts are expensive!! Definitely check the brush roll. Ensure its spinning well and brushes are great shape. That power nozzle motor should be more powerful than Filter Queen!! Any vacuum you use, may continue to pick up some dirt even though a different vacuum was just used. But it should be minimal, unless that rug just wasn't cared over the years. | ||

Central vac airflow
Not always. There are many factors that can effect central vacuum airflow such as the hose. Here's some baird meter readings from my Broan CV-40B for example these were taking pulling the hose right into the central vac
Broan 1 1/4 wire enforced: 0 Aerus wire enforced (unknown diameter larger than 1 1/4): 2 Crushproof 1 1/4: 2 Hanmi 1 3/8 crushproof: 4 The installation of the central vacuum can also effect it's airflow the length of the run, the diameter of the pipes, the number of turns in the pipe. My central is fairly old and doesn't have the power of modern units i know a beam 225c will pull a 5.5 on that hanmi hose which rivals even my best canister, and that's their basic model. | ||
