- I thought I bought a leaf blower on line, but what I got was much smaller than expected. But still fun to characterize it. It didn't cost much and should be adequate for getting the leaves out from under the deck.

I don't think the people who made this even put this amount of thought in.
this is definitely an off-the-shelf design, hobbled together with whatever the cheapest parts that could be found then checked it just doesn't explode.

Looks just like the small single battery makita blower. Good info, you always seem to make these bland topics so interesting.
yep. it is. i actually have makita one, which is great for what I bought it. I need to cut those tabs off though.
That looks a lot like the blower I use to pump up air mattresses for camping.
It's about the same price too.
I was looking for a lightweight blower for my deck. ua-cam.com/users/postUgkxgioZQl3J5wPGAeDINzbieKbT5qomSEx3 There are some huge trees around my house and the leaves and pods drop all over my deck. Having to move furniture around to sweep has become too big a chore. This blower was the answer. It is light enough for this 70yr old lady and powerful enough to blow all the tree droppings off my rather large deck. Thank you B&D. Be aware the cord is not included. I use a 3 prong outdoor cord 25' cord for my 12' x 20' deck. The cord retainer works very well, but don't try to pass the plug through it. That is NOT how it works. You just have to loop the cord and it works great. One of my best purchases. Very happy.
"Hun what were you doing in the basement all night?" "Oh i was fully measuring all characteristics of the cheapest (non) leaf blower i could find, and making a video about it" "Ok dear... you missed dinner again" ;-)
At first I thought, “this video sucks”. Then towards then end, it’s was obvious that “it blows”. Great work as always. Thank you. At one point I was expecting a mouse to be part of the analysis.
I like your practical spirit and way of measuring things
That was fun to watch. Looking forward to the next video.
love this random stuff
I'm LOL'ing the whole time imagining the manufacturers of this little blower with jaws on the floor.
I love your videos, always interesting.
My gf laughed at me behind my back thinking I was watching videos of people vacuuming.
If there was a way to cut the high end frequencies from the audio, that would make the videos more pleasant.
Videos od people vaccuming are quite amusing...
Vacuum reviews! Great channel
I like the one with lady vacuuming without the hose connected : ) ua-cam.com/video/VG7qg-2tjkQ/v-deo.html
RTX Voice can cut out the sounds of hairdryers and vacuums. (While leaving voice relatively unscathed)
It's pretty impressive
if he made a video about vacuums you know you would be watching it
lol on blowing everything off the table immediately after plugging in the tiny thing
Fantastic analysis
Skookum tool reviews with Matthias??? I'm so down! Let's see more of this!
Funny I stumble across this video! I actually have the exact same unit, I use it for a dust collector for my CNC.
I have this same blower but in blue and another brand. It's not amazing but it's handy to get rid of sawdust and getting a barbecue started.
i also have one in blue. The motor sounds rough but it's still working after a lot of use. As well as blowing dust out of my workshop i've used it with a long steel pipe on the end as a blower for a make-shift wood-fired forge..similar to your barbecue use!
maybe good for a wood fired oven or furnace.
@@Francois_Dupont I use my battery powered blower twice as often for starting fires as I do blowing leaves. Probably still haven't justified the cost, but it sure beats a 200 ft extension cord.
@@bradley3549 i bought a "fire bellow"? tube thing. this resemble a big chopped off telescopic antenna. they are about 3$ on ebay. very light weight and portable. it sure depend on your intended use, but for backpacking its great. in winter you can start a damp cold fire in a snowstorm in a hurry with this.
i know this is a bit off-topic, but it can help some people know this exist and for the price its a great item.
@@Francois_Dupont I just looked those things up and they are pretty neat for camping! Never heard of such a thing. Sure beats blowing! But it's not going to get a 60" diameter fire pit full of spring cleanup going in a hurry like 450 CFM of blower can.
What, the wasp vacuum was unavailable for conversion to a leafblower? =D
The wasp vacuum. I remember that! Ha!
Looks like there is room enough in the volute for a larger impeller. Hint, hint.
there is room, but for the RPM, wooden would not doo. Also, for the impeller size, the volute is sized right.
@@matthiasrandomstuff2221 have you considered getting a 3D printer? I think you are the type of person that could do some even greater things with a 3d printer in your arsenal.
@@nefariousyawn Guess he will just make a 3D printer out of wood and stuffs lying around in his workshop.
You can actually get wood filament! ;)
Half of Mathias’ videos are about why he doesn’t think 3D printers and CNC machines are worth the time/effort
Such a cute little blower! When I buy a shop vacuum, I always make sure it's the type with a detachable head that can be used as a blower. Mind you for that to be a viable option you have to have a need for a shop vacuum. I think Matthias favours dust collectors.
but what do these cost? Might be cheaper to buy a shopvac and a blower.
@@matthiasrandomstuff2221 They're only marginally more expensive than the ones with a regular motor unit. But if you don't need or want a shop vacuum to begin with there's no point.
I had one like that. Then I gave for my father and he loved it to the point he stopped using his big one that runs on gasoline! 😂
Nice review video
Simply genius!
I had borrowed one that had a variable speed on it, loved it, but they were so damned expensive, and then i found this~!~ The WORX $50 blower. I read reviews, etc. decide to give it a shot, and OMG, i love this thing. Quiet at low speeds, devastating at high.
I have a similar one, it's great for blowing dust off and drying stuff, better than a 600 cmf leaf blower actually.
How long were you planning that last sentence? 😄 I do admit that I was surprised at the results, given how small that thing is.
It took a few takes to get it right.
i bought a leaf blower/vac for $10 5 years ago and hooked it up to my table saw and i use home cyclone vacuums for each scroll saws . now i clean random dust once a month instead of twice a week.
I have the battery version of this and it’s awesome for cleaning out gutters.
Attempted to replicate your on axis test with cordless Makita DUB182Z and freshly charged 18v battery. Got max speeds of 8.3m/s without short nozzle and 10.8m/s with short nozzle. My results are probably skewed high by the design of my JDC Electronic Skywatch Eole Kite Windmeter with horizontal propeller needing equal wind on both sides for accuracy. The max speeds I achieved, especially with the nozzle likely had more flow on scooping side of gauge's propeller.
Matthias, our youtube friendly teacher xD
I have the same blower! I use it for the ribbon burner in my forge
I've got a 120V cordless leaf blower, would recommend.
I have a 2 stroke Shindawa backpack. It's OK. I need to rebuild my Giant Vac. It's worn out.
this looks very similar to a blower that I got from costco a couple years ago for $19.99. It was marketed as a "workshop blower" or something like that. though the costco one didn't have the vacuum capability.
probably came from the same chinese factory. The "vacuum" thing is just an added joke. Not usable.
The one with 12 inch long cord? I have it too, actually use it quite a lot after I cut off the plug and extended the cord length.
@@matthiasrandomstuff2221 agree on vacuum feature. At least on my cordless makita, which is very similar in size to kingcanada. But works great so far for what I bought it for (blowing sawdust of tools etc)
@@greentjmtl yup, that's the one. The molding for the casing is different, too. My Costco one has a sort of foot below the impeller housing that allows it to stand up on a flat surface. But not while it's running, I think
That's Matthias for you! :D
Yep, so far the revenue has paid for 2 of those blowers, so far. Should be great for blowing up an air mattress. Thanks for sharing.
I think this blower will be a good and cheap solution for cleaning dusty computers or amplifiers
So good I was Blown Away
If you look at the name, it says Performance Plus, which is I believe the same as the old battery powered saw that you used to make your circular saw blade sharpener.
Hm, I would be interested if putting a tiny little slope into the nozzle would help to create a kind of vortex-like airstream - resulting in more throw distance (hope that´s the right term for Wurfweite?) and maybe also some improvement for scraping the leaves out of the corners.
Yeah, but the design you came up with (the silent one) is better than all the others. I did some refinements in SketchUp to your original dimensions (rounded edges, thinner profile than what's safe in wood, minor tweaks) and it's honestly, one of the best blower units i've ever used and it's silent, which blew my mind when you posted the video. It certainly solved my moisture problem in the basement and i can run it at night, and no neighbor complained. I'm actually considering ordering some metal to make an even bigger one than what i've done so far in 3D printed parts.
Probably work great to force air into a foundry... Thumbs Up!
Dude this is reminding me of tinkering with Payday 2 builds
Awesome!
I have one of those of a similar brand, and one made by Ryobi as well. Mine were designated shop blowers. I find them more useful for shop dusting than compressed air, and great for blowing out shop vac filters without causing damage. I however have a 16 foot door I can open while I'm dusting!
Yes I need to get one of these. Sometimes I have to run my table saw in the winter with the garage door closed. Even with dust collection it makes a huge mess. Just wait for a warm day and pull this thing out.
I love this style of video. Should we begin buying those kinds of tools for you to take apart and explain?
Sure, if you want to, send me some. Favourite thing to take apart might be a kubota tractor :)
@@matthiasrandomstuff2221 lol
Matthias, All interesting points. But how does it do under the deck?
INTERESTING & Fun Tech . .
Kinda impressive for such a tiny electric leaf blower
This is something my dad would worry about. Me being the person that just buys it, and throws it away.
I have a quite similar product by Makita, and it is a wonderful helper on my home renovation site (roof included). I do not want to miss it any more. Price in Europe is about 60 euros.
Yeah the little DUB182Z is a wonderful tool. Makes one heck of a wind for a tiny battery powered blower. Smaller impeller than this one, quite a lot faster spinning. I love that thing for cleaning up after trimming the lawn under my fence.
Now I'm curious how well the dust collector would work as a leaf blower. :D
I took the blower off one of my dust collectors to try under the deck, and it worked ok. It blows about as hard as this one.
How does it co pare to the small Makita battery blower vaccuumm, thats what I would like to know. It looks very similar
I'm curious what would happen if you smoothed out that filter part in the nozzle. Probably negligible, but still interesting to see if it was slightly more laminar
given how little the inlet screen made, I don't think it would be enough to really be measurable with what I have.
And here I was expecting different impeller designs, modifications to the housing, etc.
the leaf blower is the most selfish tool out there. It's tagline should be:" it's your neighbor's problem now..."
Ideally, one uses a leaf blower as they would a rake; blow the foliage/debris into a pile, and dispose of that.
However, yeah... People seem content to just blow it out into the street.
@@PBTophie I blow my leaves into a pile and then leave them in a pile in the middle of my yard. Which is also a stand of woods. Woods, leaves, seems to go together OK to me. Most of my property is undeveloped. I do have some grassy area by the house though.
My neighbors lawn care guy decided instead of picking up the leaves and disposing of them, to blow them over onto my flower bed that is right next to property line. Jokes on him, the leaves helped protect from frost and are growing even better than in years past.
@@lobitome I'm glad I don't have neighbors. Well, I do on one side but there's a stand of woods between my property and theirs. They're about a quarter mile away. You'd need an F4 tornado to get a leaf from one property to another.
I've found that if I don't rake up the leaves, after a windy day, the leaf fairy has taken them all away for me :-)
(but the poor bastard down the bottom of the street must be doing something wrong, she never takes any of his leaves)
I always thought these mini blowers were meant for cleaning up work spaces not leaf blowing. That's not to say they won't work as a leaf blower as you have shown. I enjoy watching your experiments and testing, please continue. If I could only subscribe to one channel on YT, it would be yours Matthias.
Works for under the deck, I wouldn't use it to do the whole lawn.
Those blowers are sold locally (Peru) as desktop computer cleaners. These get very dusty due to the particularly dusty environment of Lima (which is the second largest desert city in the world, after Cairo). You have to do the blowing outdoors but I have to admit it does the job effectively.
those are called shop blowers or jobsite blowers, they're blowing wood chips and dust around instead of sweeping. The first think you did which was knock everything off your desk with it, is pretty much the intended purpose
I bought the same one and use it to clean out my computer cases (see Carey Holzman vids on it).
if you added a trumpet to the intake you can prob get a little more air flow as the intake air doesn't have to tun the sharp corner
The blower looks like a Milwaukee M18 BBL Leaf blower.
Yep, that's an air mattress pump (the locking mechanism on the input/out is a giveaway), with a dream... (Aspirational nozzle extension)
I use this tiny lead blower to stoke my fire pit.
Whats the name of the song playing faintly in the background?
Would love to see Matthias do 3D printing on this channel
We’ve seem you build dust extractors for the shop. How about a DYI leaf vacuum for the yard ? I’m betting a Wandel-matic would suck the grass up by the roots!
for something that gets used once a year and clutters up the place the rest of the time, not worth it.
Actually, after I posted this comment, I found a video on your website where you’d detailed how someone else had accomplished this using an old lawnmower engine, a homemade impeller, and a bedsheet as a filter. Thanks for the info in any case…
These are always a safe bet: one way or the other, they blow.
id like to see a velocity stack on the intake
Matthias channeling his internal AVE, haha love it
That thing certainly blows.
I have one. When I hold it with my right hand it sucks my pants and stops the airflow. It's annoying
Question please ...
As a guy who can’t bend down too much, I would be tempted to fit a longer nozzle to the end. In that situation would it be advisable to have a more parallel tube, or still have one that gets smaller like the one that came with it?
Thank you.
you'd want it to get smaller towards the end, but just towards the end
Matthias random stuff ... thank you :) like your work.
It says variable speed ? Is that by removing the nozzle ? or did i miss something.
there was a dial on the handle
@@DK-Design makes sense. I did not notice it.
It has a dial. To be honest, I haven't tried turning it down from MAX yet
I didn't get an ad on the video. :( now your out a "leaf blower"
Sound of the leaf blower is a bit loud at the end. makes it hard to follow you, at least on my old phone
We have an old used leaf blower that it's still in working order if you want it.
if you are in Fredericton, I'll take it!
$21 is amazing
What's the name in the online website? Does it do international shipping?
King canada sweating during the whole video... ;)
I buy a few electric model but really , a thermic one is paradise to compare with the electric ones ...
The best of the best is "NO F@ wire !!!!" , it s very noisy but you do the job with very less time and result is better !
07:25 You just skimmed over that whole static pressure measuring setup. Looks like a couple minutes worth of video explaining that!
just a U-shaped hose with water in it.
Nice to blow away wood chips in the shop!
here's an idea for your next experiment. Can you test if PVC dust collection piping with no grounding can actually explode or combust? I'm sure you're aware of the larger discussion on this topic and I can't think of a better person to make this experiment happen:)
Easy. Find somebody whose dust collection system exploded on account of lack of grounding. If you can find someone, then it can't explode. If you can't then don't worry about it.
This video doesn't suck.
I for one I'm very disappointed! (chill! keep reading) I was fully expecting a video of Matthias picking up a leaf blower from the trash, running tests and adding some scraps of plywood and jointed hardwood and making it into a much more effective leaf blower than the original one. Thanks for posting this man! your scientific approach to common day things is very entertaining and educative.
being "disappointed" with a free video, it speaks volumes about you.
@@googleaccount3555 Obviously there's always the thick person who doesn't read the complete sentence... kudos my dude! you get the stupid person of the week award!. Come get your lollipop and go eat some glue by the corner.
I did read the rest of the comment, and I thought it was the typical disrespectful "you should have gone way over the top" kind of comment.
@@matthiasrandomstuff2221 well, that wasn't my intention at all, it was a sarcastic way of saying I'm impressed (as usual) on how you go about doing your thing. Please accept my apologies if it my sarcasm didn't land the right way.
@@JesusUruchurtu1 whatever you called me you called matthias by proxy. and look at you now. speaking volumes again xD
We used the Makita version for removing dust from Alpha servers. Not a battery version that time. I believe there was a knob to reduce the power to prevent components flying away 😂
I use my air compressor to de-dust my computer once a year. Powerful enough to de-dust the insides of the power supply just from aiming the nozzle into a cooling slot.
“Much smaller than I thought it would be”... lol, for $30, I’m surprised it even works at all...
I recall years ago buying a shop vac that the motor head would twist off and you could add a snout and use it as a blower or a bag and use it as a leaf vacuum. I guess it made too much sense, why would industry sell you one thing when it could sell you 3 different things?
Because customers aren't always willing to pay 1.5x as much for a more complicated shopvac that doubles as a poor leaf blower when all they need is a shopvac.
Huh, since most shopvacs, specifically the Ridgid ones, are full bypass motors (because you cant suck liquids with a flow through motor, the liquid turns to mist and motor dead), simply plugging the hose in the exhaust turns them in a blower. And it's no joke. They blow as well as they suck. Try to keep a straight face when reading.
This was a subliminal commercial for King Canada
could you combine a meat grinder and a leaf blower and call it a 'beef blower'?
to be a good leaf blower you'd want to throw as much air mass as possible
I’d have just returned it... I’m glad you didn’t though :)
Before or after you took it apart? :)
If your dust collector is drawing less than 745.7 W, it's not exerting 1 HP.
Might work to blow sawdust off of your tools as well.
Totally, but it just sends it dowmewhere else. I prefer sucking it with a hose.
Takeaway: a leaf blower is not a dust collector. Got it.
A leaf blower for ants!
Enjoy the blower my comment just contributed to.. :)
how about a 3D printed Venturi on the intake? :)
Len Conrad He not a big fan of 3d printing
It is a leaf blower. It will blow exactly 1 leaf.
Bettcha 50 bucks he builds one from scratch with an old washing machine motor before this whole "shelter in place" mess is over. 😎
