How to disassemble and repair the Zelmer Jupiter vacuum cleaner

Hello, I would like to share how to disassemble the Jupiter vacuum cleaner without damaging it and fix one of the reasons why the vacuum cleaner does not work. I have the following vacuum cleaner:

First, unscrew 2 screws at the front, then 4 at the back

Next, we need to pull out the front flap by prying the hinges and pull the flap out and now we can remove the top.

Now it`s time to unlock the hooks above the wheels, insert a thin screwdriver on both sides and pry:

Now let`s get inside, after checking the switch and wiring, I found that there is no voltage coming from the cable reel, so we pull the reel outside:

We unwind the cable, taking care not to release the spring lock that locks the ring with the spring, otherwise we have to adjust the spring tension so that it winds up the cable completely. Once the cable is unrolled, we remove the black insert by prying the catch with a thin screwdriver:

Now I am disassembling the center where the entire contact slider is located, I inserted a thin knife, prying the extreme catch, and at the same time inserted a screwdriver and pryed the bottom to push it up.

After careful inspection, it turned out that the cable above was torn off. We solder the cable and wind the cable on the reel, put everything back together, put the reel in its place and close the engine, check the button to see if it rewinds the cable:

Connect the switch board and check if it works:

We assemble the rest of the housing by screwing the remaining elements together in the reverse order. That`s it, I think maybe someone will find my tips useful.

You described it nicely, which is a plus, I also repaired several such cases in my career. This is a typical fault in vacuum cleaners. Regards

And I assume this is the case


And peace of mind.
If you were at Zelmer`s training, you would know that it is a disposable part that breaks when taken off and a new one is put on 😀

And we didn`t attend training and we fix it Seriously, is there a new model of this slider in which the wires don`t break? Or just another new slider. Regards

This slide from #3 looks like it could be the new stripper. Because the wires are on connectors, not soldered.. Maybe they also gave better cables in this new disposable one...

Hello, I have a problem with disassembling this bush remover. I unscrewed everything, but it looks like something is still stuck there (as in the picture). Does anyone know how to arrange it here?

Helpful topic. Just today my Jupiter died and the red wire in this slider is broken in exactly the same way. I`m wondering whether to replace these thin wires with thicker ones. After all, it`s 2000W. The old cables are a bit stiff, as if they were already severely overheated.

Thanks to this post, I managed to remove the flap at the front - there was some problem.
I once had a problem with this retractor in a Solaris and I simply managed to buy this part. It has been working since then (I think I broke it during disassembly, but I didn`t attend the training ;)

Now I have a strange symptom - it`s probably electronic - the vacuum cleaner only works when the potentiometer is set to the maximum, unfortunately I don`t know... I suspect a transistor because it works, but not to the full extent. If I set it lower than max, it doesn`t turn at all, it just jerks. Can anyone help with this topic?

Remove the control board and carefully check for cold solder joints. I would put my bet on the potentiometer. I suggest washing this potentiometer with some isopropanol or white spirit and blowing it out with air, perhaps the resistance path is dirty. This resistance path may also be damaged (worn), in which case the only option left is to replace the potentiometer or the entire control board.

Thanks @adadzio2! My jupiter didn`t give up the ghost, but it sucked weakly and got hot. Of course - after replacing all the filters and the bag, there was no change, so I decided to disassemble it. That`s how I found your topic. Thanks to it, I got to the engine, which (at least in this model) is tightly wrapped with a sponge and then enclosed in a plastic casing with two outlets... Also clogged with a sponge.
I took the dismantled sponges into a bath in dishwashing liquid and after 20 minutes of washing under running water - black water stopped coming out of them, and the sponges at the outlet of the housing became almost white!
At this point, I don`t know yet whether his work has improved, because the sponges dry before I roll the old thing, but I am optimistic.
At the same time, I also washed the housings, blew out the engine itself with compressed air and cleaned the potentiometer board with isopropyl alcohol.
I will let you know what the final result will be.

All right. I put it back together and there weren`t even any spare parts left ;)

A few notes about the manual:
1. First, remove the flap closing the bag chamber. Only then should you disassemble it.
2. There is no information about the need to release the clip under the cable (due to ignorance and innate stupidity, I broke it)
3. The cables from the reel are very short and one is permanently attached. After removing the top (with the slider), you must first dismantle the black cable from the connector on the board and remove the switch from the holder - this way you gain a few cm of cable and there is less chance of it breaking off.
4. It is also a good idea to dismantle the motor cables (two black ones, coming from the same board with the potentiometer) before removing the casing.

Generally - after cleaning all the internal sponges, washing the rotor and all plastics - the vacuum cleaner works a little quieter, and after working for about 5 minutes at full speed - the air blows slightly warm (instead of very hot, as it was before) and in the trunk to the small tips, it`s cold too.
I won`t comment on the suction power, because in my opinion it sucks better than before (it may be a placebo effect), but my wife says she doesn`t notice any difference.

Mine is probably 860W on the nameplate Nowadays, household vacuum cleaners with power > 1KW are no longer produced, because the EU prohibits...

Thanks to @adadzio2 for the detailed description. The last two steps with the cable reel are the hardest. I took mine apart just to find out that I had a new generation glider and after assembling it to throw it away, the vacuum cleaner came back to life.
