Introduction

If there is a loss of suction, an easy first check is the suction hose. Remove the suction hose and examine it for rips and breaks, replacing it if needed.

this is not even accurate!!! the cover does not come apart easily as pictured. it's a nightmare that's what it is. the part where the actual handle is at that's not the problem, the real problem is right above the suction ring. it won't budge. i've been trying for two days.

She's right, the handle halves aren't two-piece on the professional models, they're a single piece and the suction ring holds them together. Some dipsh*t on Youtube is all, "Oh, just use a butter knife to separate the pieces", but I snapped a knife in half without separating them. Pretty sure it has to be at a certain point, or is a one-way snap assembly.

I'd do more research, but I wound out just hammering the clog (a friggin' toy, of course) out the way it came in.

The suction ring on the NV501 must be pried off toward the open end of the tube. A wide flat blade screw driver between the handle and the suction ring works best. The suction ring doesn't need to be rotated any specific direction for removal. It will take some force to snap back onto the handle during assembly. Rotational orientation is important during assembly, so the suction ring can function as designed.

The hose wire is also soldered to a ground plate in the handle, and a ground lead that contacts the aluminum suction tube . You can see the wires in the 2nd picture of step 4. I assume this is required to eliminate static electric charges that could ignite a dust fire when shorted.

Does anyone know of any helpful material on the “SHARK ROTATOR NV750W SERIES”? I had a blockage in the bend of my handle and while attempting to free it i damaged my contacts. Anyways; because I did this damage myself I did not abuse the warranty and just ordered a replacement handle and hose for $84.00 CAD. They sent it fed ex right to my door which is nice because I live in a rural area. However, I connected the new one just as you would and to my disappointment; when I pressed the power button on...NO POWER, no power on any of the three settings and yes I have plugged it into a functioning wall outlet.

Dulce Elote above is 100% right.

I took their photo above to heart and used a hacksaw to cut around the top piece so it looks just like the photo.

Hose replacement becomes easier.

Caution so be sure to solder the hose to the copper wire you see when you take it apart

That was absolutely worthless as the handle does NOT come apart as show! Duct tape to the rescue…not replacing the hose, just patching for now. ☹️

I thought I would never get that ring off but I finally did. I started with a chisel and just pushed it in to leave just enough crack to put in the number zero flat head screwdriver. I twisted the number zero flat head screwdriver to widen the crack just enough to get a number 2 flat head screwdriver. Then when I twisted the number 2 flathead screwdriver the ring poped right off

This is not working at all. I bought a new hose to replace old one. Not fitting. Two plastic parts are not two separate pieces. They do not come apart.

I don’t think Caroline Swanson took apart the handle of the Shark vacuum. She was pretending. I can’t get the %#*@ handle apart as shown. You can’t go green with plastic parts. We are a throw away society pretending to go green.

we have removed all the screws and cannot get the handle apart either. It is a nightmare. If we ever figure it out I will give an update

UGH!!!! anyone that figures this out, please post!

OK so I just got this taken apart and put back together. As another person has already posted I used a small screw driver to first slip in between the collar and the white plastic handle housing. I then twisted the screw driver to pry up and eventually unsnapped the collar from the housing. (twisted it from being in between flat until I moved it about 180 degrees) Since I was using a METAL screw driver to pry against plastic I did leave some dings in the plastic. I did not have another alternative at the time and just tried to be careful not to crack anything. If you can;t get it to pop off by twisting the screwdriver you may not be using a big enough of one, BUT start smaller and work up until you get it. I did it with a 1/8 size.

Going back on isn’t as bad. I just forced it down on one side till it “clicked” into place and then did the same on the other side. If that side goes on hard you can tap it down with something if you can’t apply enough pressure by hand.

I’m just wanting to wash the gunk outa my hose as is seen in another lady’s YouTube. She didn’t say how to remove the hose but washing it out was a breeze. My question: if I wash the hose still connected to the handle, will it damage any of those soldered wires etc parts mentioned above??

I just want to wash the hose, too. This thing will not come apart no matter what I try. Does anyone know if washing it while still attached to the handle will cause an electrical problem?

How do I get the suction ring back on?

sue - Reply

I just sat it where it goes then put the vacuum pipe on it and banged it on the ground till it clipped back into place

Hopefully you got it by now, but maybe others need to know. I used a flat screwdriver inside the vent area to both pry it off and pull it back together. Pushing it on might work with some serious force, but leverage and persuasion seemed to work well.

Allen Scott -

Omgosh what a mission. Got it all apart eventually and just taped the hose up as it was split right up the top. Stuck it all back together and works like new (definitely doesn’t look new after fight to get it all apart) lol

The ring does have to come off. I used a flat screwdriver inside one of the vents to separate the ring enough to place another flat screwdriver on the backside. Using both places to pry, the ring came off without much effort. As for the soldered wire, I was able to cut the plastic from the hose down to the break. With that excess removed I just pushed the remaining wire onto the pipe. No soldering required. Reassembled and back to normal. This may not work if the damage to your hose is much more than a few inches past the handle. If it is and you can't solder it back, maybe try cutting it back and overlapping the wire. Tape or a zip tie might be enough to keep them in contact. Mayne even a bread tie. LOL!
