Dumpster Li-ion vacuum cleaner 

Can't believe Microsoft still hasn't gotten into this business.

What, do women not shave or something? This ridged gender stuff is bullshit.

Where the HELL is my comment? Damn RU-vid!

Or broom😂

Fortunately his batteries are also long at 0% :)

It might be a good idea to decontaminate the area where you took the cleaner apart, in case of larva or eggs@@DiodeGoneWild

Cheap low quality corded is also better than 90% of cordless

Bags are a horrible impractical thing

@@erminbajric4633 Oh yeah, because having to deal with dumping out all the dirt and other nasty shit out of the vacuum cleaner is so much more convenient than a paper bag that you just take out, throw away and put in a new one. Also bagless suffer from turbine/motor damage way more often. Also bagless means inhaling and spreading fuck ton of dust in the house every time you empty it out, because agitating it just a little puffs up a cloud of dust that you just vacuumed for it to settle on the surfaces AGAIN. Bagless is shit.

@@erminbajric4633Bagless is way worse. I had one of those ONCE. Never again.

@@Bananovskyyy do it outside, not that big of a deal

In their defense it's 40 minutes on low setting when the unit is taken apart and the impeller is in free air. When the airflow is restricted (such as by the filter, etc) the current will go down. Also as the battery voltage falls the current will also fall. I'd say the advertised 65 minutes is plausible.

@@eDoc2020 isn't it the contrary ? if the airflow is restricted the motor will draw more current to compensate ?

@@bobjohn4086 It's not really intuitive but no. With a centrifugal pump power consumption goes down then the flow is restricted. When using a vacuum cleaner you can hear the motor speed up when you block the hose.

@@eDoc2020 wow I've never think about it like that, I always though this noise meant that the motor was "forcing". so if I understand well, when you block the hose, the motor turns at full speed because it has no load, no air is going in or out of the volume where the fans are. but when you let air be sucked into the tube, the aerolic system creates a suction and therefore the motor has a load

@@bobjohn4086 Pretty much. I even did some tests when replacing my furnace blower motor. When closing all the ducts the power usage went down to 70%. Due to inefficiencies and internal drag the load won't be zero when blocked. A vacuum cleaner motor also has a dedicated cooling fan to ensure it doesn't overheat. This fan also has another "secret" function: its mechanical load on the motor limits the max speed. A truly unloaded series wound motor is prone to revving itself to destruction.

What about robot vacum cleaners?

​@@znoop72What about them ?????🤔🤔

Dragging the cord around vacuuming does kinda suck. But I bet this cordless vacuum was only a fraction the power of a corded model. It certainly has more points of failure too. So that convenience comes at a heavy price.

I interpreted the cat's comment as a remark on him using a battery powered screwdriver lol, to show the irony

Commercial cleaning crews often use backpack-style cordless vacuums, especially for stairs. It eliminates the trip hazard (for third parties) of having a cord snake down the stairs, and having to go up and down stairs repeatedly to unplug and replug the cord.

My aunt once had problems with her Kirby not having any suction. I turned it over and found the entire suction nozzle area, from the beater brush all the way to where it attached to the motor, was completely packed full of crud. Literally you couldn’t even see the beater brush, it was completely embedded in a solid cake of dust and hair. Wtf… I cleaned it out and replaced the snapped beater brush belt, and of course it then worked like new. I wonder how many times she “vacuumed” the carpet without realizing it was not doing anything at all.

The PWM sounds awesome !!!

Makes sense because the FET has no heatsink on it

Unlike your NiCd drills, modern Li-Ion power tools have plenty of power and they last 4x as long as NiCd. You do have to learn to proclivities of Li-ion though. They *hate* to be charged while hot, or discharged to empty. I haven't needed a corded drill in years, and I use drills & drivers all the time. Battery powered is just WAY more convenient. Like, you're up in a 110 degree attic working on an AC air handler. Might not be a plug. Why waste the time & effort using a manual screw driver? That said, battery powered sweepers are for picking up crumbs, not vacuuming a carpet.

well that is a cordless vacuum they didnt say it would work

I agree with DiodeGoneWild's position same with yours to still like cables in priority of purpose of use. Nowadays it has become fashioned to have every electronic device designed cordless. From an environmental point of view it's a disaster to say that the copper for a let's say 10 metre mains cable is hard to mine whereas Lithium as rare earth element for the battery pack on the other hand is way more hard to mine in reality! And you are absolutely right about wearing out: If not caring about Lithium batteries they soon die after few years if you do not charge them from time to time! But at 20:24 I am little bit of critisism with his argument because some women or men use to shave wet on body, therefor it's good to have shavers designed cordless not to get an electric shock from mains socket.

When the wire broke powering the agitator brush motor the brush wouldn't spin anymore. So the owner took it out because it wasn't turning anyways. They probably tried to fix it and when they couldn't they just didn't put it back.

Here, we mostly have bathroom light switches also at the outside of the bathroom, but in my appartment they put them inside. And there are wall sockets in the bathroom. Normal ones, no isolation transformer. In my mother's old appartment, the socket is above the bathtub! In new bathrooms, the sockets just have to be a certain distance from the bathtub or shower.

@@DiodeGoneWild You wouldn't really want a power socket with a built-in isolation transformer of c. 1.5kVA rating for a hair dryer! UK laws in general are pretty paranoid about safety, but I guess every thing you are not allowed to do represents a way someone died horribly. Where I live is a former coal-mining area, and there are still just some people alive today who remember exactly why some of those laws are on the books.

Almost all European countries allow sockets in bathrooms. They have to be on RCD but there are many older installations from the 1980s or ealier without RCD and people are fine, they don't keep constantly dying from it. Also, in Central and Eastern European countries, aluminium wiring, usually 2.5 mm2 was commonly used until the early 1990s. Many houses are still like that, not renovated and just fine. In 1960s and older houses that were not renovated you can also find cloth and rubber insulated wires.

Actually, this is a bit of a myth. The regulations regarding the use of electricity in bathrooms in the UK are complicated but in essence they boil down to the fact that you cannot put outlets or wall switches within 0.6m of a bath or shower which is similar to the rest of Europe. RCDs are compulsory for all circuits now. It's a bit of a silly rule because it doesn't stop you using a hair dryer in the bath or having a fan heater next to the shower.

UK electric laws are extremely good. I bet there's a lot of bureaucracy behind of it, it's better to keep natural selection working against dumb people and having the ability to fix own outlets and wiring for handymen

I discovered when woodworking how much torque an old-fashioned bit brace can deliver. You can buy adapters that let it handle socket wrenches or screwdriver bits. You almost have to buy an antique one, though…

Planned obsolescence helps the economy. It keeps consumption high. I owe, I owe, so it's off to work I go!

It's getting even worse now that fluorescent lamps were banned in the EU in 2023 and now most cheap chinese fixtures have integrated, potted non-repairable and non-replacable LEDs. Even with mercury in fluorescent lamps, I doubt that importing LEDs from china instead of producing fluorescent lamps locally in Europe is any better for the environment.

Thanks :)

Just the average chad grindset

When things get messy, call for Nessie.😏🇬🇧

Thank you for your support ;)

I guess the charger is either just a normal flyback power supply relying on the primary current limitation, or maybe it has some secondary side current sensing, going into the optocoupler besides the voltage feedback. But I've never seen one personally.

I thought of this, I hate wasting too, but finally I decided not to donate this biohazard with the charger and the brush missing.

The power supply is used in a constant current mode (it has to have internal current limiting circuitry). The circuitry of tha vacuum cleaner disconnects it from the battery when the battery reaches 29.5V.

@TheSpotify95: That’s not how lithium charging works - you NEVER just apply the voltage from the power supply directly to the battery! Proper* lithium charging requires highly accurate current and voltage control (to within a few mV is typical in an off the shelf charger chip), performed in multiple phases, the main ones being a constant-current phase until the charge termination voltage (around 4.2V) is reached, followed by a constant-voltage phase until the termination current (typically 1/10 of the current of the constant-current phase) is reached. Nobody builds their own lithium chargers from scratch anymore, because you just use a lithium charger IC that handles it for you. So the 36V is the power supply for the actual charger IC inside the vacuum, and that charger IC then regulates that down to the voltage applied to the battery. Why they chose to do this nonsense - relying on the current limiting in the power supply, and just disconnecting the power supply when the voltage goes too high - makes no sense. In another comment, someone said that this vacuum model ruins batteries fairly quickly, and this dumb-ass charger is probably why. *proper in the sense of safe (not going to overcharge batteries and cause them to explode) and optimizing the lifespan of the batteries.

For vacuuming things with loose fabrics, like curtains.

@@tookitogo Sure, that's the plausible reason they give if anyone ever asks, but no human being has ever done such a thing. But they'd have us believe that activities requiring the low power setting (such as vacuuming curtains, or lace, or the delicate eyelids of a sleeping infant) are so common that they use this as the basis for their battery life calculations. Balderdash!

@@jhonbus I have, on occasion! But of course using that as a basis for battery life is highly deceptive, I totally agree.

yes

Germans apparently love vacuuming stuff so much the battery only lasts a month

Yeah, but his content makes it worth putting up with. Besides, I can't imagine what I'd sound like trying to speak someone else's native language.

after a first video i watched i forgot about his accent, i can eeasily understand every single word he is saying, a very quality men

Maybe with age too, but definitely with the modern content they watch.

No, it does not.

some bad ones like liCycle in Arizona have 95% efficiency recycling mixed battery chemistries in the same machine@@johnsmith7676

For many a decade, the rotating brushroll design was a (and still is) a staple of upright vacuum cleaners, as traditionally they were agitating the carpeting (think Hoover's old slogan, "It beats as it sweeps as it cleans") to dislodge dirt and debris from the carpets which was then pulled up by the airflow, and in the process also helped to comb the carpet to make it look nice, straight-suction vacuums though with no rotating brushes are not as effective on carpeted surfaces, meaning you don't get as clean a carpet as you would if you had used a decent vac with a brushroll...

That is why I try to move the suction head on the carpet :) It does have a brush strip built in - so kind of the same effect 😅

So you're saying they threw it away because it sucked, which sucks, since it would suck less if it sucked more?

Usually you can get replacement brushes. But this thing is kind of a heap so probably not worth it.

@@twocvbloke I've seen many a Hoover Junior field-stripped! This was a very popular upright vacuum cleaner in the last century, with a motor of about 400W (judging by size). The brush roller was driven by a round-section rubber belt from a spindle on the end of the motor armature, which was designed to slip (with a characteristic burning rubber smell) if something blocked it from rotating; an identical belt was used to hold the inner paper dust bag onto the pipe spigot. And the exhaust air was quite cool. Many people in the UK complained about the EU limit on vacuum cleaner power ratings; but the fact was, manufacturers were gaming the system by using cheaply-made, inefficient motors which generated a lot of waste heat to claim inflated wattages. 1000W of kinetic energy actually usable for cleaning and 1000W wasted heat allows you to plaster "2000W" all over it in huge text, but it will not clean as well as 1200W of cleaning and 300W of heat. And the exhaust air from these cheap and nasty cleaners was always red-hot. Using more copper in the windings and more steel in the core would have reduced the losses, but would have increased the price of the machine; so they pretended a bigger wattage was a positive thing, and the ignorant customers wound up paying more every time they vacuumed their carpets.

This vacuum had two faults. They had the wrong charger and that wire was broken to the head.

Like, the same connector, in the same place, without any kind of keying? Lunacy!

For a car, this would work only if it had a different attachment (a flattened pipe), but still, it has much lower power than a mains one, which it's trying to compensate using the rotating brush. Giving it to someone is tricky because there's no charger (and a normal person doesn't have a bench power supply), there's no brush, it's quite dirty, nobody knows what it was used for, and of course, I can reuse the batteries from it :). And also make another video about it - the autopsy of the pack. And don't take everything too seriously ;). Of course I'm getting older, the passage of time tends to do this to people.

There are vacuums just for cars which use 12V cigarete lighter plug for power and usually are 120W

Got a Miele from 20 years back.. Not quite daily use, but of course works perfectly to this day. The model from today is not much different but half the power of the old! 800W instead of 1600W!

Well, It might be possible if the windings have short turns or if the bearings are failing.
