that 65 minutes is marketing math !... 25 minutes on high setting + 40 minutes on low setting gives you the 65 minutes 🤣🤣

[@eDoc2020]

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.

[@bobjohn4086]

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

[@eDoc2020]

@@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.

[@bobjohn4086]

@@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

[@eDoc2020]

@@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.

I had a similar situation where I got a free lithium ion vacuum that was missing important parts.

It looks sketchy, but works great.

Cordless vacuum cleaners rely on the rotating brush head to make up for the lack of suction power (compared to mains powered vacuums). Without an operating power head, this cleaner would have been quite ineffective, even on hard floors. That is probably the reason they threw it away.

[@twocvbloke]

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...

[@3mekG]

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 😅

[@jhonbus]

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

[@mysock351C]

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

[@bluerizlagirl]

@@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.

[@tookitogo]

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.

It was probably thrown out because something happened to the brush part in the head, since it's missing. Perhaps they broke it while trying to untangle hair or something from it. EDIT: Looks like you found the problem with the brush motor, which would definitely explain why the brush was missing if that's what was broken.

[@1pcfred]

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.

It's interesting that the PWM frequency is quite low, just 560 Hz in this case. Maybe they wanted to minimize the switching losses in the mosfet?

I have two cordless vacuum cleaners. Both are restored from trash. For regular floor are just enough, but not for carpet. They're even good for cleaning inside a car or camping. Electric shavers now are powered by batteries because they could be used in wet environment, eg. with shaving cream and could be totally submerged in water. Noone will gave you a guarantee to not beeing shocked when you will use shaver in water even via proper insulated power adaptor.

[@twocvbloke]

It makes me glad I have a stock of traditional vacuum cleaners (oldest one being somewhere around 1967 to 1970, which is the one in my profile pic, a Kirby Dual Sanitronic 80, which I need a stepdown transformer to use, it being a US-only vac with a 120v motor!), these modern screamers, battery or mains powered, are about as effective at cleaning as a broom with no bristles... :P

[@sebastian19745]

I got one of these cordless vacuum cleaners from Lidl with lots of blue LED indicators and white lights; that model had a stand where it charged the batteries. I never was curious about the charging circuit and because it had a small power brick that went into the wall, I assumed that the entire charging ang balancing circuit was inside the cleaner or in the battery. Now it makes sense to have a small power adapter for few hundreds of mA. However, I did not used it too much (maybe 2-3 times at most), I like better my older one, powered from the wall so I gave the cordless one to my sister, as a present with all the accessories and manuals in the box, like new. Few months later, she also gave it as a present; she does not liked it either...

[@michaelfisher9671]

Good find. I always look out for small vacuum cleaners at the side of the road, hoping that they will be cordless, so I can get the battery packs. But usually they are mains powered small vacuum cleaners that someone has cut the cord off.

[@Chris-onyt]

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

[@ryanomalley430]

Loved the video! It doesn’t surprise me that someone would throw this out, people would rather buy a new one than fix what they have. When I was a teenager, my grandfather and I would pick up vacuum cleaners from the trash and repair them. 90% of the time they were thrown out because of dirty filters or clogged hoses. We would repair, clean, and resell them for $10-$25 to people who couldn’t afford new ones.

[@ruben_balea]

I got 4 second-hand but almost like new Parkside (a Lidl brand) PNS-300 mains powered screwdriver drills, those are basically a normal cordless drill but with a 230V motor and a nice 5 meter power cord. Their power is only 300W but since they have a gearbox with 2 speeds and the chuck capacity is only 10 mm (3/8") they can actually be used to drill. The chuck can also be removed by pulling a collar and then the shaft has a hole for the common 6.35 mm (1/4") hexagonal bits.

[@Alchemetica]

All my power tools are AC except 2 Makita 12V Nickel-Cadmium battery drills. Why I have 2 drills? The ni-cads died on the first drill and to get two new ones it was cheaper to buy another drill with two new batteries in a case with a charger. Crazy! The dog makes a rare appearance.

[@guygordon2780]

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.

[@pauldery7875]

Great video, on what to check for if someone has this type of vacuum if it's not working. Keep doing what your doing, I love it. 😊

[@antibrevity]

Yup. Putting batteries in stuff that could plug in to AC power just a few feet away is ridiculous for multiple reasons. Not only is it wasteful to mine and create batteries for devices that could simply run from AC, but it's also a boon to brands and stores because battery-powered devices *always* wear out sooner than AC-powered devices. This is made worse because brands don't allow batteries to be replaced in many devices.

[@andiback]

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.

[@bluerizlagirl]

Actually, in the UK (where the Neutral is earthed, so you can get a shock from touching just the Live wire), **no** power sockets are allowed in bathrooms except a shaver socket with an integral isolating transformer using a split-bobbin construction to minimise capacitive coupling to Earth, so you cannot get a shock from touching just one wire. This is quite low power, but OK for recharging a cordless toothbrush or shaver and should last long enough to get a shave even with an ancient shaver before the thermal cutout operates. A switch on the primary side is operated by inserting the plug of the shaver. As there is a transformer, there are usually two outlets for 110V and 230V. Hair drying has to be done in some other room (I don't think anyone ever made a hair dryer with a battery motor and a butane gas canister for heating; or maybe they did, but it just never caught on). Also in the UK, bathroom light switches must be operated by a pull cord, or be outside the bathroom.

[@DiodeGoneWild]

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.

[@bluerizlagirl]

@@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.

[@mernokimuvek]

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.

[@petehiggins33]

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.

[@Gameplayer55055]

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

Mains vacuum is great for carpets, but in my flat there are no carpets, only vinyl floor, no need for high suction power(that missing brush is actually useful, has quite a lot of torque) The only thing surprises me is human dumbness, if my vac dies I'll replace batteries, transistors, and it will work.

[@superdau]

Battery powered vacuum cleaners are just made to be thrown away, especially those that are also supposed to be used to clean the floor (as opposed to the smaller hand held ones). People either leave them in the charging station all the time, which destroys the li-ion cells in a year or two (they lose capacity faster the longer and closer they are to a fully charged level). Or people almost never use them and find the batteries fully self-discharged and again damaged. As for manufacturers: the worst offender I got (I repair things for people) was from *Bosch* (a Bosch Athlet 32.4V). If a single cell of the 9S pack drops below 3.0V, the electronic board bricks itself! Even if you charge the cells (via the balancing connector of the battery pack for example) or replace them with new ones, the vacuum will not work again, but always indicate a battery fault.

Hey that's interesting. I also once found a vacuum cleaner next to a dumpster, but like 1 year ago (but a small battery powered one for cleaning a car). But I also found it without the charger. And so I did try powering and charging it, and other than that it worked, charging it (using a separate power supply), I found out it also pulled as much current as possible from the power source to charge it even though it was rated 300mA charging current. So it also relied on the separate charger to limit the current. And now that got me thinking, I found mine without a charger and so did you (at least not a compatible one lol).. So could it be possible that the chargers also end up breaking, maybe because of some cheap current limiting circuit? Just a thought.

[@DiodeGoneWild]

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.

have to disagree with Diodegonewilds thinking here, i much prefer cordless (higher end cordless to clarify, these have a ton of suction even when the brush is off) over wall powered, especially while vaccuuming stairs its just much easier to not have the heavy motor to drag up the stairs and the cord. also anoying is having to unplug and plug back in the corded one if you are beyond the lenght of wire. of course if you use cheap no name ones Corded is better.

Someone in my family had this vacum cleaner after 1 year, the battery died, so I replaced the 18650 cells and it lasted again yust 1 year. So it seems that the bms or the other ciruit is destroying the 18650 cells.

It was probably thrown out because someone couldn't connect it to WiFi and decided it has to be broken.

The cat question is hilar😂ious

If you see a bagless vacuum cleaner at the side of the road pick it up, the chances are it's only the filters that need changing I've come across a few cleaners like that. Just wash or change the filter!👍 Oh, and please please please STOP buying cordless vacuum cleaners people.

Corded vacuum cleaners suck, but not as bad as Battery powered ones.

Jo, baterie ve vysavači a v holícím strojku mě pěkně štvou. Ty ve strojku mi už odumřely jinak funguje 😑

Pros of cordless vacuum cleaners: No hassle with the cord Charge it with excess solar or cheap off period mains Needs less energy ... Yeah, that's about it. I still prefer to vacuum my car with a corded one, because they have way more power, but for the occasional crumbs on the couch it is ideal

[@xDR1TeK]

Don't destroy the battery pack. Seeing it's practically functional with massive power in it. Do something with it.
