The vaccuum cleaner suddenly sucked. By which I mean it failed to. It's not like I overuse the poor thing. :)
But I vacuumed the bedroom carpet and was still stepping on "bits" (Ayla likes to eat in the bedroom). So I checked the bag. Empty. I disconnected the hose and checked it. Empty. It's a cannister vacuum so I checked and I disconnected the tube from the head and hose. Empty.
"SIGH* I know what that means. The Power Nozzle (that part on the floor) was clogged. So... I took it of the push-tube and examined it. There were 6 bolts holding it together. I coudn't see what the heads of the bolts were but guessed at phillips-head and was right.
Took a while to loosen them. The 2 halves of the power nozzle still didn't want to separate. Well, usually anything that is put together can be unput together, so I examined it for a while. I could see the different halves of it (different colors made it sort of obvious) but I couldn't get them to separate.
I finally realized that 2 bolts I thought were loose weren't. I went at them harder (they didn't want to release at first). But succeeded. And it still required some prying and pulling. It gave a liitle, so I knew it wasn't locked in place with catch-pins (those evil things that are designed to connect together once and never to be unattached except with special tools).
I got the final 2 bolts ("machine screws" technically as they don't have nuts on the other end and are more like untapered screws). And finally the 2 halves of the power nozzle can apart.
It was packed full of cat hair. I shouldn't have been surprised, I suppose, but isn't that what a vacuum cleaner with a powered brush is SUPPOSED to remove successfully?
Talk about a mess! The entire thing was packed with cat hair (and around here, that is what "dust bunnies" ARE. It's not like *I* shed much. :)
The brush roller looked like a cat hair brush used too often. And when I removed that, I discovered the entire 10" of tube leading to the hose was packed. The cat hair wasn't even GETTING into the sucky tube, nevermind the collection bag.
I was amazed at how much cat fur I pulled out of the power nozzle. I think there was a "Marley-volume of fur". But with pulling some out with needle-nose pliers and pushing at the back end with the handle of a screwdriver, I got it all cleaned. There were some deep corners with fur and the pliers got those too.
But to be sure, I took the power nozzle out on the deck and banged it on the rails. Bits of dried food and grit came out! Quite a lot. So I took it back in to reassemble the power nozzle.
The brushbar didn't want to stay in place. So I thought of what the part HAD to look like and went back out the deck to find it. I did, and was exactly what I thought it would look like. Fit back perfectly.
I screwed all the machine bolts back in but was missing one. Damn, more searching. Finally found it on the lawn below where I banged the grit out on the rail. Whew!
Then I re-vaccuumed the bedroom carpet. Worked perfectly. So I tied a label to the hose "Not Working? Clean power nozzle". I don't have the world's best memory, so reminders help. 10 years from now, when I've forgotten about this, that will give me a clue!
