I spent some time reviewing the comments and I *think* I finally understand what some have been complaining about. Yes, there is a screw in a difficult spot which fastens a gray piece of plastic to the outside of the assembly. I demonstrate removal of the problem screw at 14:10 in the video so that I can finish removing the gray plastic pieces covering up the bearing endcaps. Another possibility is that the manufacturer may have changed the mold at some point in production to address an issue found in other units, so you may have a screw somewhere that I didn't see on the one I repaired. I may go back through the footage and post a supplemental video to make this more clear.
Thank you for an incredibly helpful video. I did the brush repair. It took me a second to figure out the “square” plastic pins on each end of the brush were removable (and needed to be removed from the outside of the chassis). Once I did that, I was able to unloop the drive belt around the cog, pull the old brush free, and make the repair. Great tip on the magnet and the repair diagram!
Thank you for the video! I’m a retired woman, not particularly mechanically inclined but was able to get my brush roll replaced on my Shark Navigator 681 model. The diagram for the screws is an excellent tip. I also taped them to the diagram and was so glad I did as this became a multi-day project. First, the folks who sell the brush roll also sent a brush with a hook with it. I thought it was a hook to pull off the belt (no instructions were included). There’s a small blade in the hook, which I couldn’t see without my glasses so I sliced thru the belt, then had to order another. It’s also good to have the long shaft T20 bit as you recommend. I was able to get the screws out with an allen wrench but it was very tedious when trying to put the screws back in. Another thing that came in handy was a small magnet that was on the end of my screw driver for fetching those screws when they drop into the compartment sideways. Finally, I’m glad you included a few words about the spring in the wheel compartment and showed it on the video. Getting it back in is fiddley and you’re right about how it sets but there’s also a small groove that the long flat piece needs to fit into.
Thank you. I never would have been able to do the brush replacement without this video! I followed your suggestion about keeping track of the 18+ screws and parts, but took it one step further. I drew a diagram of the bottom and top of the vacuum head and put numbers in the spots where I removed screws. I used painters tape on each screw to label each one with the corresponding number from the diagram. Worked great!
Thank you for this video, and mentioning the spring! Putting my machine back together, I was struggling at that point! I got it back together!(lift away DLX NV586)
Thank you very much for your very helpful video. I wouldn’t have been able to change the roller without the assistance of your video. Followed directions carefully and my vacuum cleaner works like new!
I want to Thank you for doing this video. I use this type of vacuum to clean at church and literally just found a replacement brush that I needed forever. I was going crazy trying to figure out what screws to undo only to find out I needed a T20 screwdriver. All my vacuum screw were t20 except 2 of them. Thank you, Thank you, Thank you!!
Thanks for the feedback. I'm thinking they changed what screws they were using depending on when the unit was assembled. I think the one I repaired in the video had 3-4 phillips screws while the other 15-16 were T20 security screws.
Thanks for a really helpful video. I was struggling to find what was securing the front centre of the top plate - it was the phillips head screw under the 'O' seal. So simple once you know where to look!! So many thanks indeed; you probably helped me get the plate off without breaking it.
The replacement comes with a set of endcaps that hold the roller in place. All that's required is to pry them off the old roller (very easy to do) and then the roller will just fall out of the housing. To be honest, there's hardly anything holding it in place once you remove the grey endcap that's on the outside ends of it. Putting the new one in place is similarly easy. Just put the brush roll into the housing and install the new endcaps that came with the new one. I can't really change the video as I don't have that unit any longer. Hope it helps.
There's a little round thing holding grey end cap on, on the belt end of brushroll. It's held to clear housing with a screw. You have to turn over to access underneath of clear housing- you'll see a screw (mine was dust covered & since that's a weird place for a screw i hadn't noticed it before) Once you remove screw you can gently pull grey end cap off (note it has two tabs on top that have to be lifted also) and then just pry white square end caps off of each end of brush roller.
The fastest way to destroy the beater brush is to use lazily the power brush instead of the bare floor attachment that usually came with those vacuums on bare floors. Particularly if those floors are tiled or textured. Those bristles are only meant for carpet. So it might be worth getting the word out on that.
NV680: A few extra steps: there's a screw holding the endcap (the gray ones he says just snap off- one does, one needs screw removed) on belt side it's real hard to spot. Then you can remove the brush roll by taking the white end caps off of each end. Brush roll will then lift out. The spring thing has to go back (just before you put cover on or it won't stay put) with leg lying in horizontal position facing forward there's a small groove (place where the black molding is a tad lower) where it's supposed to rest. For some reason I have 3 screws left I've been at this 2 & a half hours & it works fine no loose wiggles I'm done 😂
It is very simple. Go get your replacement part and take a look at it. You should see a little plastic cap that's pressed over a ball bearing. If you pull on it, it will easily come off of the bearing. These same plastic caps are what is used to hold the brush roll into the housing. Just take a flat bladed screwdriver and gently pry them out of the assembly from the outside surface. At that point the brush roll will just fall out of the assembly. When you put it back together, make sure to use the endcaps that came with the replacement part. You can't use the original endcaps because the bearings are a different size between the original and the replacement. Hope it helps.
Disappointed no I dont know how to finish getting roller out. I've gone as far as you and the roller has no more screws but still wont separate .If you wont going to show all of it why bother???
It isn't difficult to complete. You'll find that on the outside of the assembly holding the roller that there are two plastic endcaps that are holding the bearings. If you have the replacement part, it comes with replacement endcaps because the bearings on the replacement part are a different size than the original. Find a flat bladed screwdriver and just pry them out. The roller will just fall out at that point.
I actually cut most of the discussion of tools because there was only one tool that was critically needed to do the job. The rest of that discussion was to help out those who might find the number of fasteners intimidating. Please remember that the audience consists of people with all different levels of experience.

Thank you sir! This just helped me change my roller on my vacuum. I wouldn't have been able to do it without your video.

Thank you for this video, I was able to replace my brush and save myself so much $$$! You made it much easier for a newbie
Excellent instructions, thank you.
This helped me with my shark rocket! Thank you!!
I thank you for your video but you didn’t show how to replace the brush roll. I can’t figure out how to get the plastic housing apart.

Use the bare floor setting.
That's what it's for.

He takes too long explaining tools, etc. to get to replacing beater bar.
