Hello there Vacuumland!

It's great to have found this awesome community of gurus - I'm a longtime owner of Hoovers, and considering a Dyson next. But right now having a strange issue with a Shark that my wife loves and hoping maybe someone with a sharp eye has seen this issue!

The video I've attached shows the issue
- Turn it on, it immediately turns off
- Wait 5-10 minutes, try again, and it works!

I usually put it back on the charger just in case, not sure if that helps or not.
I'm considering buying a new one, or just upgrading to a Dyson, but otherwise, this vacuum works great.

I've taken it apart and done my best to maintain it, but this issue stumps me. I'm wondering if this is a battery issue and a replacement would fix it? But when it runs, it runs fine.

Maybe a faulty temp shut-off or something?

Thank you gurus for your time!

On the brush roll has a stop brush roll feature. Like on some power nozzles has a reset or thermal reset.
If that's not the problem the battery connection or a short.

Seems like a computer cut off to me. At first it thinks something's wrong and turns off. After that time, it resets and the problem no longer exists.

Though I'm not sure how computerized these are. I wonder if they have a clog sensor?

Unfortunately those things not designed to be repaired.

My suggestion would be to replace it with the same one, if you really like it.

But really go with a more reputable brand for daily use.

This is the same thread going on Reddit here

It helps if people actually help the person to try and fix the problem and not just being a zealot against a particular brand.

What's funny is those "more reputable brands" like to charge high OEM prices that nobody can afford, purposely reduce parts availability from third party sources to ensure only OEM sourced parts can be used, and they do not carry parts on-site either - so you are stuck with a giant paperweight. Same problem - just a higher price point. Riccar won't even send me a PDF of a user manual from their archives.

Now to actually help fix the problem - I own one of these, refurbished, and its lasted 2 years and still working.

It is not a brushroll stall, because when that happens, the light will blink an alert after stopping.

It is likely a battery conditioning issue, they are Ni-MH packs (not lithium) and even though they have no memory, they can suffer from power fade and just abruptly stop. Once the battery recuperates itself and rests it can carry on like nothing happened. This can also happen if the battery has a thermal safety cutoff inside the pack to prevent overheating/fire risk.

I gleaned this from the manual, try this and see if the problem is solved. If not, you likely have a battery pack that is just worn out and needs to be refurbished or recycled, which is not uncommon because this vacuum is now over 5 years old. Batteries Plus+ can refurbish packs but I am not sure what they charge, or if it is any more expensive than a non-OEM or used OEM off eBay.

--------------------------------

BATTERY RECONDITIONING If you experience shorter run time over the life of the vacuum, perform the following battery reconditioning steps. These steps can also be performed as monthly maintenance for maximum battery life.

1. Charge the vacuum for a minimum of 7 hours.
2. Run the vacuum until it turns itself off.
3. Charge the vacuum for a minimum of 7 hours.

To enhance battery life, this vacuum is equipped with an advanced feature that will shut off the vacuum when the battery is almost fully discharged. If the vacuum shuts off while in use, charge the unit until the complete oval around the power button is illuminated, indicating a full charge.

Thank you everyone for the input, and especially huskyvacs!

That is awesome input and I haven't done that before - I'll try this tomorrow and report back with my findings.

I've seen battery packs on amazon for around $35 which is significantly less than a new vac. I'd happily replace the battery if I can rule out other parts.

Thanks again, will be giving this a try!

Thanks huskyvacs. I don't own but I will own this vacuum.
It's a power issue. You ruled out the sensor reset.
You probably solved the problem.
Telling people to not by plastic crap is funny. Since 2970s most vacuums have plastic on them. Kirbys, royals,filter queen, and many others were and some still are.
So this preconceived notion plastic bagless vacuums are trash is funny. I advise you go try a plastic bagless water based vacuum rainbow by Rexair. It's at top of the food chain in vacuums.
Please if you don't like the vacuum don't spout off. Not everyone can afford a different vacuum.
I've fixed a few sharks. They are good vacuums. I buy for $10-$15 spend maybe 2 hours totally refurbishing vacuum. I spend 0 to do this and sale $30-$100. That is $15-$85 profit.
I refurbish because there good vacuums and usually you don't have to spend anything.
The person gets a good vacuum. I also educate them on how to care for the vacuum. Every vacuum I sale I tell them how to maintain the vacuum.
I get to work on vacuums increasing my knowledge, make a little money and educate people.
I'll give 2 examples of high profit. I bought e2 type 12 rainbow. $30 is what I paid for it. I paid $20 for a filter. I sold it for $350. $305 profit.
I bought a silver rainbow $150. I cleaned it up no there money into it sold for $600. $450 profit
The last I got a rainbow platinum. I paid shipping$75. It had everything. I replaced power nozzle yolk, power nozzle hood, dolly amongst others. I was in it $225. I sold it for $850. With fees $400 profit.
I made $1150 on 3 vacuums. I've sold many others. Selling rainbkii learned how to fix and work on them.
So financial gain, expertise, enjoyment fixing vacuums and lastly selling and teaching people how to maintain a good vacuum.
If you look at it through my eyes there's oppurtunity if you change how you view certain vacs. It's also rude to just pop off.

^ This.

Seriously, if someone - anyone - is asking for help repairing something - ANYTHING - I make it a point to ALWAYS help them and encourage them. We live in a time where the number of people who are mechanically inclined and seek to repair things (rather than throw them in a landfill) is declining rapidly. There may yet come a time when there's nobody left to fix anything, and where would society be then? Hmm?

Encourage repair and DIY. Especially to those who are beginners! We need these people to exist in our world. If you have knowledge, the burden falls upon you to spread that knowledge!

Oh yeah, let me get down from my soapbox here...

If it's a NiMH battery pack, you might be able to rebuild it yourself. NiMH cells can be bought on ebay. It'd only be a matter of opening the pack and measuring the cells. But then, $30-something for a pack is not a bad deal.

Real odd question.
Craftsman 12v nicad (I think that's the older batteries name) cordless drill.
It smells like carbon brushes are toast. Can you open drill clean motor replace carbon brushes. It's an odd question but with your electrical and mechanical knowledge you would know.
I do have mechanical ability to do this but should it be done.
Thanks
Les

Les, I'm sure you can. Haven't opened one myself, but I have opened other similar type drills. The brushes are probably not meant to be replaced - not that it would stop me - as in, the brushes are probably hardwired in. Nothing a soldering iron won't fix. Also, you'll certainly just have to measure the brushes and buy similar generic ones based on their dimensions. Is the battery any good, though?
