Shark Navigator NV680 Brush Replacement

Looking online for a video about this particular subject, I couldn't find a similar video to use for my own repair. I created this one to fulfill that need since third party parts are now available. I'm hoping this will help you get through doing the same repair on your machine.

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.

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.

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)

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!!

[@nosuchuserid]

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.

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.

[@nosuchuserid]

Thanks for the feedback - it's good to know it's been useful.

[@jesseg9655]

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.

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.

[@Kennedy4OurCountry]

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

[@christophersimpson6815]

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.

[@nosuchuserid]

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.

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???

[@nosuchuserid]

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.

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

[@nosuchuserid]

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.
