Great quality video.👍I found it very interesting. My Bosch Athlet wasn't that old when the batteries started to fade. I very seldom used Turbo. If I did, the batteries would drain within like 2-3 seconds and it would need a new charge. The next thing to happen was that the red sensor light came on and stayed on. If I plug it in to charge, it starts charging and after about 20 seconds, the red light comes on, stays on and stops the charging process. I thought it was a filter warning. I've cleaned the filter but it didn't help. Although, having said that, I didn't put the filter in the washing machine like they state you can in the user manual for a serious clean of the filter. Because it won't charge, it is basically useless to me now. We were never happy with the Bosch Athlet. We both complained that it just pushed particles further forward instead of sucking them up - especially larger particles on hard floors. Your video highlights another design issue with this device that thankfully I didn't encounter. I've bought a Dyson. Yes it is much more expensive but it is far superior in every way. The wife and I are much more satisfied. We will see how long the battery on the Dyson lasts 🤞In the meantime, my advice would be to steer clear of these vacuum's. They are nothing but trouble and the lifetime of the battery pack is ridiculously short.

Excellent. I've seen other videos showing the failure of those two wires but nice to know what happens if they short when they break. Both my mother and I have Bosch Athlets (but not the zoo models) and although I'm gentle with mine, I envision I might have to open one of them up at some stage. Hers is getting on to nearly 4 years old I think. Apparently the handles break easily as well so it seems the design could definitely do with some 'toughening up', but it's a decent vacuum and she loves hers. I was expecting to have to shell out for a Dyson when I took her to look at stick vacuums but she preferred the Athlet due to the weight being more distributed down the handle. She found it easier to manoeuvre. Only problem is it's fatter and doesn't get under my bed. Oh well still have the old traditional type for occasional use under there and other nooks and crannies. Thanks very much for the tips.

Hi Steve.. I know it does get quite a bit of grit collected in that corrugated tube, however I can't say I've noticed much falling out when its picked up. I would noticed that too I think as the vacuum is stored on a hard surface sometimes. I can force some of the grit to fall out though If I rattle the hoover around a bit though or it happens to bang against the cupboard doors when I need it. Not loads though. Cheers John

Thanks for the video, John. You mentioned adding a loom around the wires going to the brush head motor through the plastic elbow. That's a great idea to protect those fragile wires. But i am stumped on how to dismantle the corrugated plastic hose and the elbow joint to expose the wires. It looks like the elbow joint should pop open by pushing in some tabs, but mine isn't budging. Any ideas? Thanks in advance.

@OrbiterElectronics 4 года назад

Not sure I understand what you mean there buddy. I didn't actually disassemble the bottom hinged joint or remove the upper end of the corrugated hose. I just removed the whole bottom plate of the hoover which releases the hoses bottom end, and got access to the motor wires that way. I de-soldered the wires from the motor and added a new piece if I remember correctly. I'm actually not sure how the upper corrugated plastic hose fits in to be honest. I still haven't wrapped the wires up apart from a little insulation tape, and the hoover is still going strong.

Hi, my fuse has definitely blown, but I’m also not getting any continuity from the one next to it. Is this normal or should I replace that as well and have you any idea what it is?

@OrbiterElectronics 4 года назад

Hi.. These devices definitely seem to have issues especially when older. Before you change any fuses and turn the vacuum back on, please remove the lower brush cover and make sure that the wires leading to the motor are NOT severed or shorting anywhere. As this is one of the reasons the fuses normally pop. If everything looks good you can certainly try replacing the fuses. But just to let you know in advance.. I have had a couple of these units where static has damaged the on-board micro-controller and rendered them dead. I have even tried switching micro-controllers on one unit hoping for a result however I fear the micro I switched with had also suffered the same fate. So it's all a bit hit and miss unfortunately with these things. It's a shame really as they are so easy to manage and use. Hope you have better luck with yours 👍

@sarahwhitelaw6534 3 года назад

Hi I'm attempting to sort out the brush intermittently stopping .. your video confirms my thoughts about a wiring break .. I've removed the three screws holding the brush 'plate' .. but I'm damned if I can get it off !! ..is this another 'strong plastic clips issue' ??? Or am I missing a screw (so to speak 😲) .. thanks !

@OrbiterElectronics 3 года назад

Hello Sarah.. If I can remember correctly, there are 7 screws that need removing to take the base plate off. If you brush/dust/blow out the underneath of the brush housing, you'll likely get rid of some of the dust bunnies which often obscure the screws holes. So.. There should be the 2 visible torx screws which it sound like you've removed already. Then there are another 4 screws.. These are underneath the thin rubber strip, the rubber strip is only clipped-in, so can be popped out quite easily. Lastly there are another 2 screws, these are underneath the little rollers at the very front of the brush housing. Those rollers are clipped-in however they are often quite tight, so try a thin bladed screwdriver etc and lever one end of each roller upwards & they should pop up. You'll then see the 2 last screws. Hope this helps 👍

@BravosUK 3 года назад

Hi, a new query, or rather a further query on the same topic. So far I have removed 8 screws; 4 which are in plain sight, two more under the removable rubber strip, and the two which are hidden under the front wheels, but the base plate still refuses to come away. It seems to be held very securely by something right at the front in the middle, where the plastic moulding is quite thin, and may well break if I give it any more than a gentle heave. I am trying to get at the drive belt in order to change it, as the cleaner has become exceedingly noisy due to what, I think is a slack, worn drive belt, or at least I think that is the problem. Any advice would be welcome.

@mrcmountain6342 4 года назад

John, thanks eversomuch for uploading this. Having similar problem. It just wont charge anymore. Ive taken it apart but cannot see if any fuzes are blown, how do you see that? Also, could it be the jack itself being damaged? It is connecting, and i have tried in other outlets, and with other chargers.. Pls help.

@OrbiterElectronics 4 года назад

Hello mate, thanks for the kind comments 👍 I know you say you've tried other adaptors to charge the vacuum, but where they of the correct voltage? Assuming it's exactly the same vacuum, it's adaptor outputs 30v so an ordinary 12v or 5v charger that just has the same size jack wont work. You can test this with a multimeter. Regarding the fuses.. You can't actually SEE if the fuses are blown (Well not unless they've literally exploded.) You will need to check them with a multimeter too (in continuity mode.) The fuses are white & labelled F1 & F2 on the PCB, (you can see them at around the 5 min mark in the video if your not sure what they look like.) Hope that helps John

@mrcmountain6342 4 года назад

@@OrbiterElectronics youre welcome! Well worth it. So no they were not the correct voltage so thats why that did not work. Thing is a new charger is really expensive for these, surprisingly so. And I do not have a multimeter. So Ill have to get multimeter and then either the charger is broken or not. if yes buy new charger if no, throw vacuum? Or just go directly to plan C and buy new cheap-ass vacuum.

@WaltonPete 5 лет назад

It can be quite a challenge to dismantle many modern devices as the designers often employ the use of hidden clips as well as screws, making it a bit of a guessing game! There's nothing worse than wondering why a cover won't come off, even though you've removed all the screws, and then having to potentially risk breaking something as the hidden retaining clips hold it in place incredibly strongly. I sometimes wonder whether it's strictly necessary to bother making it with screws if the plastic parts grip so tightly!

@OrbiterElectronics 5 лет назад

I'm of the same thinking Pete.. I don't see the point at all of using the type of clips that just break off. Especially when it would be no effort at all for manuracturers to replace the things with say.. a simple locating sliding lug or tabs etc which are secure once the screws are tightened. These are also perfectly suitable for preventing vibration etc It really is as if manufacturers make these things to be thrown away as soon as theres a problem, no matter how small. Thanks for the comments friend 👍 John

Did you use a torx SCREWDRIVER cus our set isn't long enough n I'm getting mighty peeved off

@OrbiterElectronics 3 года назад

Hi.. You'll need an extended shank torx driver bit (IIRC a tx10 or tx15.) A standard torx bit won't reach the screw head. Also please be EXTREMELY careful to discharge yourself once you have the vacuum open.. The IC chips on these boards seem extremely sensitive to static charge. I even killed my own vacuum just touching the PCB and ended up buying another one.

@philipsmith68 4 года назад

Thanks for the video! Saved me a lot of time especially with the plastic clips. I bought a new brush head, and then was disappointed when it didn't start working. I opened it up and tested the fuse which had no continuity. I also tried shorting across the fuse and sure enough the new brush motor came to life. So I'm purchasing some new fuses. Just wondering though, I was a bit surprised that if I short out the connection with the power switch off, the motor still starts! (by the way, my circuit board is covered in a clear thermoplastic??? protection which will make soldering messy :( )

@OrbiterElectronics 4 года назад

Hi Philip, I was going to say you're welcome, However.. I fear you may have wasted your money on fuses there my friend. If the motor starts when you short the fuse (Switch in OFF position) there is perhaps another component in the circuitry that has shorted (and this is allowing the motor to start with fuse circuit closed/shorted.) This may have been the reason the fuse blew in the first place. If you're doing anything else with the PCB.. Please wear some nitrile rubber gloves to protect the pcb from static. The reason I say this is that..Unfortunately I have never managed to repair or help anyone repair one of these vacuums once failed, and I have had lots of people contact me about them. I fear that the PCBs and components on these boards are very sensitive to even the smallest amount of static charge. So once the PCBs have been touched they rarely power-up properly again. I even killed my own vacuum whilst trying to help somebody else to test specific voltages :( Please disconnect the batteries! Otherwise I fear that a new fuse will just blow again. I think I would start by checking for shorted transistors/MOSFETS etc on the PCB with a multimeter. Regarding any silastic or PCB conformal coating on the board.. If it's the thick rubber stuff, you can remove it carefully with a pick etc. If it's just a glossy conformal coating you should be able to solder through that, But beware of any fumes just in case the coating is something else. Hope this helps a bit Regards John

@philipsmith68 4 года назад

@@OrbiterElectronics Thanks for the reply John. The fuses arrived and I had another look at it, but it looks like you are right. This time I put the voltage meter in the small socket where the brush head power connects. Sure enough, it read 20V all the time . I think rather than risking messing up the board completely I'm just going to leave the brush cable disconnected at the board and use it as back up cleaner in the basement. Too bad. Not too worried about the £2 spent on the fuses, but I'll have to see if I can return the new brush head (about 80GBP!) to Bosch. Thanks again for the advise!

@OrbiterElectronics 3 года назад

Hi.. I have changed cell packs on a couple of these vacuums, however only 1 worked correctly afterwards. These units seem very temperamental and fail easily once the main PCB has been disturbed (IMHO they're very sensitive to static.) The units that only fail shorting then blowing SMD fuses are often repairable. However ones that have had the PCBs unplugged & handled always seem to be problematic afterwards.

@OrbiterElectronics 4 года назад

Thanks Graeme. I'm sorry but I can't remember exactly the size (from memory I'd guess a Tx10 or Tx15) but I don't have a unit handy to double check. Please note that they are NOT standard Torx Bits. They are 'SECURITY TORX BITS'. The security part means that each bit has a special hole drilled up into the end of each bit, which accommodates the pin in each screw head. If you have to buy a set of Security Torx Bits.. get the long ones, and the ones with the rounded shank. Most of the cheaper ones have a hexagonal shaped shank which often doesn't fit down narrow holes.

@OrbiterElectronics 3 года назад

Hi. Obviously water has got in and caused a short circuit. The problem now is that the unit has run until it's batteries have been totally exhausted. Hopefully the cells circuit protection will have protected the cells from dropping too low which is good, but the cells must be tested & charged up again to make sure they're ok. The cells should all be a suitable voltage e.g.. not below 2.5v per cell. If the battery voltages are very low, then they may have been damaged beyond repair :( Also the vacuums circuits will need testing as something has caused the unit to run continuously. This could be something as simple as a wet switch, plug socket etc, OR it could be a shorted component or short on the main PCB itself. So unfortunately you're going to have to either have this checked out if you can't do it yourself OR go through the circuitry step by step to figure out where the problem is. Please be aware that these PCBs are often prone to failure, even just handling alone can kill them due to static charge (I''ve done it 😧 ) and replacement firmware is unavailable for the affected IC. This then renders the irreparable :(

You could certainly try it but make sure you connect it clup correctly. Also be very carefully handling or soldering the PCB.

Hi Simon, unfortunately it sounds like you may have the dreaded ESD issue, which I believe I've inflicted on two vacuums. And as far as I know there's no fix for it. It seems that even just touching the pcb, static can kill the on-board micro controller. I initially opened one of my vacuums to help a friend diagnose his, and even though I know for a fact I didn't phisically damage anything, I must have inadvertently shocked the micro. I even tried transferring the micro controller over from another board, but no luck here either. I got some charge lights to appear but the vacuum still wasn't charging as it should. So unfortunately I just had to salvage the batteries. Sorry I'm not able to offer any help here :(

@@simonlansdowne9888 It seems that once the micro controller is damaged on these devices the whole system is kaput. I was considering perhaps re-flashing the chips firmware initially but I've no source for a known good firmware file, and Bosch didn't get back to me following an email. You could possibly get the vacuum to somehow work again.. But please remember that modifying anything that uses the likes of 18650 cells has risks, so care has to be taken when charging etc, especially if done without a specific charger, as the cells need balance charging really! The original vacuums circuitry did this. However If you have an 18650 'balance charger' or a dedicated charger then that's fine. But charging cells individually will reduce cell life/efficiency. If you do decide to try and use the vacuum again. You may need to fit a heavier switch, depending on the max current capability of the original, then run suitable wires down to the motor via an adjustable step down (buck) converter etc, you can pick these up for about £8. As the motor may just burn out if fed with 28v directly. I can't remember all the specifics now. John

Sounds like you have created a short circuit to the motor somewhere.. Or the switch mechanism is jammed etc. Likely when you refitted the power connector or reassembling. If you did any soldering.. first check that you didn't inadvertently create a short circuit between any connector pins etc. Also check that no wires etc have become bare or jammed and shorted between the plastic housing of the vacuum.

If it dying like a battery though you're likely right in that the cells are finished. I can't really help you with the battery replacement bit, as I've not done that. But no doubt with tools and some perseverance it can be done. Just be very careful with the batteries if you intend to re-solder new ones in, if your unsure though I would advise against a DIY job.

I’ve got the motor assembly out thanks to your video!! And see that they are all soldered in. I’d have a go if they weren’t ALSO seemingly spot welded on the 18650’s too lol! So sod that for DIY dad time blowing up in the garden. The Mrs will think I’ve put the lights up earlier than usual. Oh well. I’ll have a look around blackpool for repairs as Bosch are ridiculous. I got mine £120 in store with Tesco offers. The battery replacement alone they quoted £99! So I’ll ask around. Many many thanks! :)

John - Orbiter ps I’ve also tried the shim in the neck just in case. No go.

@@Mr_Gadge .. Hahaaa 👍 If the unit still shows or acts like it charges up properly, it does sound like a dead or faulty cell in the cluster. You could test the cell pack voltage at the output terminals.. When charged the battery cluster should read around 25volts. Much less and a dead cell or a worn pack is likely. If you do have 25volts, perhaps have a look for visually bad components on the PCB, or dodgy solder joints/pins etc. £99 is a little expensive for a repair, however I guess 7 decent cells would cost around £45 to begin with.

@@OrbiterElectronics it can work fine straight after a charge for up to 5 mins, then stops. Switch it back on again, and it'll last up to a minute, battery flashing light soon comes on and it stops. Had a look round the PCB and gave it a canned air dust. Can't see any. I'll try meter the cells thanks! -Didn't think it would function fully for a few mins if a cell was down.

@OrbiterElectronics 3 года назад

If you are happy with disassembling and testing items like this, I would advise that you may need to take apart the top of the vacuum as in the video, & also disassemble the lower brush head assembly to access the motor. Check that the wires going to the motor are not shorted or broken (this happens a lot as the wires down there are twisted all the time whilst in use.) Also with a multimeter and the vacuum handle connected, that you have continuity between the wires at the top of the vacuum down to the motor. Also check the two small SMD fuses on the PCB, if there has been a wire short down by the motor it will blow the SMD fuse/s on the PCB also.

Hi I have a bosch athlet 25.2v. I replaced the battery but now the problem is it doesn't charge. The light comes on blinking for a couple of times and then it's off. I tested the slow blow fuse and nothing is broken. It just doesn't charge. I used the same replacement battery

@OrbiterElectronics Год назад

Sorry for very late reply Steven. Unfortunately the problem could be many things.. From the replacement batts having been LOW on voltage or faulty and not starting to charge properly, to static damage to the PCB. As I believe these boards are very sensitive to static. I'm sure I killed one of my own Athlets just by touching/testing it's PCB. I had no blown fuses or failed components & good batts.. but it totally refused to work. I wish I could point you in a specific direction to help here but I can't, I've even been asking others including Bosch for any advice regarding this issue but I didn't get anywhere. And this is why I think either these boards are very susceptible to static, Or they have a firmware issue that is perhaps leaving many with dead vacuums 😡 I would still initially check that the charger is outputting the correct voltage (this will be printed on its casing), and if you're able to.. put it under a slight load as well to make sure it's actually working.. After that, I'm afraid you're in the same boat as I was.. Testing components looking for failed parts. Sorry I can't be of more help.

How do you know the batteries are ok? If the vacuum is couple of years old or more the batts could still be the issue as often they charge but don't retain capacity.

@tomaszs5954 Год назад

Great video! Mine lasts for approx. 1 minute on setting 3 and then dies. all batteries show 4.03V when fully charged. Strange.

@OrbiterElectronics Год назад

These vacuums are great initially, but for some reason once they go wrong they're normally finished. This is why in a lot of my responses to people I mention firmware, as I believe there is an issue with it on these devices which when triggered.. It renders the vacuum mostly faulty. Which is sad because they are great when working. We even bought another one, but itf it started playing up I wouldn't even bother trying to repair it again, unless it was something obvious.

Thanks I was just mesure the output on board for the main motor and its shows 0V

@OrbiterElectronics 3 года назад

Its always worth checking the fuses its. There is two of them on the PCB. To be honest these PCBs fail very regularly and they're not worth repairing in most cases, especially if the board needs replacing.

Hi,my problem is that it charge for a 5 min. and switch off. I can clean for few min and the level of battery go off.Can you let me know why this keeps happening please?

@OrbiterElectronics 3 года назад

The problem could be quite a few things. If you have a multimeter I would advise you firstly check that the charger is working properly.. if it is, it could be that the batteries are degraded (especially if the vacuum is a few years old) Batteries do not hold a full charge forever, so their run time can get shorter and shorter over time as they degrade, sometimes they will only hold a partial charge, as in your case. If the problem is the batteries I think you can get new battery packs from Bosch, but these tend to be very expensive, almost the price of a new vacuum.

If its sticking on the lower level.. I can only guess that perhaps a switching transistor or part of its associated circuitry has failed. I've known a lot of these things totally fail when fiddled with electronically, so I would perhaps suggest just using it on the level that is working now.

@OrbiterElectronics 3 года назад

Was the polarity correct on the DC jack you used? e.g. Centre Positive. If the DC jack you used was Centre Negative you may have damaged components on the PCB. You can 'sometimes' pick up parts for these vacuums on Ebay, however if you manage to find new parts they tend to be very expensive, and on the other hand unfortunately used parts are NOT guaranteed to be good 🙁

I may have a bit of time later so I will perhaps take a look at my vacuums PCB Test Points to see what they read, then you can compare yours. In the mean time perhaps you could have a close look at your PCBs components.. Check if any are burned or smell burned. Have a close look at the main ICs (U1 & U4) check their tops surfaces for cracks or small burn holes. Also.. if you know how... test the main transistors (marked on the PCB.. Q15, Q16, Q17) for open/short circuits. Please contact me next time via the 'ABOUT' section at the top of my RU-vid channel.. This way I can send any images easier via email. Cheers John

Yes i've been there with that type of vac john. i did the wire repair on a identical looking vac and the wire broke in the same place lol. I was lucky though, there was no short between wires :-D. I lifted the sprung power connector and added an extention to the down wire, then pulled the down wire down to solder on to the motor.

I can hear in your accent you're from merseyside. Can I drop off my Bosch athlet circuit board to you for repair? It is not charging

@OrbiterElectronics 2 года назад

Hello Robert, I'm sorry but unfortunately I'm not able to take on external repairs at present. Also, as your issue is with the charging of the unit (unless it just a failure of the wall adaptor..) It's likely that it has failed due to a problem with the main control PCB or it's IC chip, this controls charging too. The IC can seemingly fail on these vacuums for no apparent reason and once failed it's not possible to repair them. This is because there is no firmware available to be able to re-flash the chip with it's software. So yes you could in theory just buy/replace the main IC chip, however it would be useless without it's control programme/software. Since making the video we have had our Athlet fail again due to this seemingly super sensitive IC issue, I even managed to get hold of a second-hand PCB (with main IC chip) however this had suffered the same failure, and wouldn't charge :( Regards John
