I have now heard from a guy who burnt the board on a 581. He said he was pulling on and off a 9 amp Flexvolt battery while the vacuum was plugged in to see the difference. He said the vacuum ramped up when he put on the 9 amp and eventually popped a circuit on the board. So there's that info. See ya!
I was using a 60v battery on mine and it burned out the circuit board. I just deleted the circuit board and wired the battery directly to the switch...that was a year ago and it's worked fine since.
Mine popped something after changing a battery. Ramped half way up and shut down. This is the only dewalt tool ive not been impressed with. Had it less than a year, hardly used it. Never for water. Didnt have good enough suction power.
@@brianreinhardt4050 Makes you wonder why it seems that they think EVERYTHING needs a circuit board now. Good work with the simple delete.
Your video answered exactly the questions I would have asked if I had known what I should of been asking. THANK YOU!
Great short review. I do small jobs and have a small workshop set up in my apartment I'm really glad you hooked it up to the Mitre saw because I'm sick of cutting outside on my landing and the cleanup involved. I want to buy this vac for dust collection just for the 5-10 cuts I make once a month
Just be sure to pick up the DWV9000 universal adapter in order to connect it to the mitre saw with the AirLock dust port.
I’ve had the cordless only model for years. It’s not the most suction in the world but it works really well and I’ve had no problems.
My bearing is shot on my 580 , no other issue of all day 5 days a week of work . I clean window openings and floor around windows after removing and installing new windows .
Best review of these out there! I just wish DeWalt would sell a version with 2x the motor power for half the battery life!
Thanks for the bringing up the issue with the motherboard.
Seems time for Dewalt to update to a newer version with more suction power. They are at the bottom of the list. I was looking to buy one and keep with my current battery system but the dewalt vaccum is less than desirable. Hate to get the Ridgid and be the only tool line in use with the battery investment.
I'm going to review RIDGID's new 3 gal that takes a bag to see what mod, if any, it would need to fit my 60V batteries through an adapter. I like this DeWalt for small amounts of construction dust and to remove water from toilets so I won't give it up for anything larger unless it's got beast mode. Will try to get that review together next week or so.
I have all Dewalt tools but at work we use a 6gal Ryobi cordless and I love it especially the wheels. Its just so easy to rollaround. I just pull it around with the hose. Thinking about getting one and a Ryobi to Dewalt battery adaptor.
Yeah even Ryobi is better. This is way overdue for an update, which is why this video caught my eye, I thought maybe there was one. I guess you could argue they are choosing battery life over performance, which may be valid, but a better option would be more power and a switch for "eco" mode.
I was going to buy one of these until I watched this video. I have the Dewalt weedeater and blower with the big 60 volt battery. I'm very happy with both of those tools. That vacuum looks very weak.
Thanks for the video.
you bet
knowing what I understand now from your review. I'd just avoid this vacuum altogether and not worry about what board it has. Dewalt has been good to me, but there are a few tools that just are not up to proper standard. The 20v chainsaw is another one, with their problem switch.
My chainsaw works fine and 2 other friends' also. Our issue with all 3 is that they leak oil out of the bottom... Even if sat flat. Makes a fun mess in your toolbox.
@@dezign187 I had the same issue with my dewalt 20v chainsaw. Local dewalt authorized repair shop told me it's gravity fed so that's expected unless you drain the oil after each use. I didn't want to drain, but storing on it's side with the oil fill cap facing up prevents mine from leaking.
Had the same problem with the vacuum, switch didn’t turn it on. Take it to service for warranty. As soon as I get it back is for sale. Got the packout Milwaukee definitely a lot better.
I'm looking at the Dewalt 581 but the performance of the Milwaukee sounds better. I hear Milwaukee tools will work with Dewalt batteries. I was interested in the option of wall plug but idk if Milwaukee has a model with both options🖖😎☮
5:04 -- Looks very much like that "burnt" spot is a voltage regulator, and the problem appears to be that it got so hot that it melted its own solder connection and then detached from the board... Yikes! That new board is interesting in that it omits the resistors but keeps the same capacitor arrangement. The actual controller chip on the board is clearly different as well, along with plenty of other simplifications over the original design. Hopefully that solves the problem!
Great comment J! 👊
Not a VR, a negative-channel MOSFET to feed the negative terminal of the vacuum motor if battery voltage is above 14VDC to keep batteries in the minimun secure recharge voltage. Dewalt batteries use 5 cells (or pairs or triplets) in series (5S), minimum secure voltage for li-ion cells is 2.8VDC. 2.8VDC X 5 cells = 14VDC.
The PCB itself is just a battery protection module that shuts off at 14VDC. Any li-ion BMS board for 5-cell series capable of at least 4 amps will do the same job. 4 AMPS is the current capacity of the inline fuse fitted to the positive terminal going from the battery accross the switch to the motor.
@@pablodignani7766 I figured it was just a protection module... I am going to try and put a 6s pack on it and see if it holds.. Will most likley make a large 6s pack with BMS just for my vac.. MORE POWER..!!
Got mine for Christmas 2020 (DCV580H) and it just stopped working a few months back. Dropped it off for warranty repair and they’re telling me DEWALT won’t cover it. Don’t they have a 3 year warranty on those vacs? Has anyone been able to get them to cover this issue?
I like dewalt but the suction and design sucks. It needs to be a box like Milwaukee and have more cfms maybe a 60v
Just bought the cordless only model at Lowe's for $30.... last one in the store, manager came up to me, thought he was a dewalt rep because he's like ya want a deal ? See this vacuum, it's yours for $30 if you want it.
Guess dewalt is discontinuing the 850 model so 81% discount for me I guess!
Thanks for this video. I am shopping around for a portable vacuum and having collected Dewalt tools, 20V and 20/60V flex batteries I might end up getting this.

great review and demonstration! and to add a tech oriented repair at the end, thank you! will be subscribing.
Welcome!
After 1 year it only worked with the cord. As i had 3 years warranty, they've send me a brand new one with another 3 years warranty. If the filter gets wet, it doesn't suck anymore, so it's better to take the filter out.
Good that it happened within the warranty.
Awesome video.
Thank you for the honest review
My pleasure Birdman!
I love the ergonomics... but doesn't have a lot of suction.
Good review. Thanks from Australia
Great comparison! Thank you!
what battery do i need mine keeps shutting off with the small battery i got from my drill
was debating on this 2gal or the 0.5gal for my Freightliner
Best review ever👌 you just won a subscriber
Cool, thanks!
Where did you get the replacement circuit board from ?
Either DeWalt's parts portal, which is my usual go-to, e--replacementparts.
Thanks for the great review and update.
No problem 👍
I bought the cordless one and returned it the same day because I didn't even know they had corded version a few months ago.
My corded one went dead while using on flexvolt battery.
Iam debating between this one and the rigid VAC4010
... very informative, thanks!
Great video!
excdllent review mate
Can you use the new lithium powerstack battery 1.7ah. Of course im expecting would be short run time.
yes
If you have a battery in the vacuum and plug it in. Does the battery charge
Unfortunately no, but great idea.
Good informative video
Great Video!!
Great video
I had the same problem with mine
If you're using the 18/20v model the only reason the circuit board is there is for the different battery types. If you don't need to use an 18v battery, just delete the board altogether and wire the switch accordingly.
I think it's just the pins on the terminal to battery connection that determine the voltage. But the board has DeWalt's electronic protection system that prevents "overload, overheating, and deep discharge of the battery." Similar to Star and Redlink only they don't promote it like Mil and Mak. But they do discuss it in every lithium tool manual. So if you remove the board keep an eye on your power bars. Otherwise, you risk recharge lifespan. Same risk you may run using a battery adapter, which I do everyday. :)
thx
Does the cordless one come with the accessories
Yes, both come with the same accessories.
bought this for my husband who has many dewalt cordless tools, but it did not come with a brush or crevice tool. Do you know where I can get an attachment set?
Not offhand. After I got my first DeWalt I thought I lost the crevice tool only to find it a few weeks later in the handle. If it's not there you should be able to find it here - www.toolservicenet.com
Hi thanks for the review. I’m wondering how powerful this tool pushed air out / inflates? I’m
Looking for a portable tool to inflate a raft and I need it to be powerful enough to overcome the back pressure from the raft. Would really love to see a video showing that feature of the tool
You should check out their inflator (Dewalt DCC020IB 20V MAX Air Inflator). I have one and it is very handy. Has both high pressure and low pressure sides.
@@michaelkies4224 thanks for the recommendation. I tried one battery powered air inflator already and it didn’t have enough juice but perhaps the dewalt one will. also, I currently only have the old style dewalt
Batteries so I found this shop vac tool appealing bc it can work on the old and new
@@dylanrobertson68 Ok, got you. I have all 20v max tools.
@@michaelkies4224 ya I might have to make the switch but I don’t use my tools often so trying to hold off
@@dylanrobertson68 It depends on the pressure you set it at. If you are airing atv tires at 7psi it fills kinda slow. If you push it to 30psi and shut it off at 7 psi it works fast. Probably a safety reason? It isn't super fast at 35psi, but it is so nice and compact, and in a carry case can be stashed easily.
So even though it looks like they updated the board as of at least 2019, you'd still go for the 581h model?
I would to avoid getting one with the old board.
Hi guys when you use it for water do you still need the filter on
I believe DeWalt recommends it stay on but I usually take it off. Check the manual.
Tanks 🤝 👍👍👍👍
👍
I can smell that board burning in my 581. Still works but expect it to die soon.
Just on the surface it looks like a melted off voltage regulator. Manufacturers are using Lead-Free solder, so what probably happened was that the voltage regulator got too hot from extended use, and the solder just simply melted off and possibly created a short circuit. The voltage regulator should have had a heat sink on with a bolt/nut to secure the piece on to avoid this from happening. Crappy design and crappy lead-free solder = Sell more.
Interesting, thanks for the comment.
Is there a longer hose to clean the car?
Not specifically that I know of and doubt this unit has the suction to support a longer hose.
Do you know if these are available in the UK?
I don’t, you can check their UK site. You can’t even find many In the US right now with the supply chain issues.
@@toolrev thanks
Amazon
Thanks
@@fordpower19 you may not care lol but I’m not going to buy one. I wanted to as I have dewalt stuff but I will just stick with my Henry hoover. corded. Henry’s are great I use for work all the time
👍
Man you got exactly same set up even that dewalt table..
What does CFM mean? Would be helpful to explain if you’re going to make informative vids. Thanks.
cubic feet per minute, referring to the vacuum's top speed for air flow
look it up on that super computer in your hand.
the time it took to type the question you could've had your own answer.
CFM is a common acronym. Maybe you should just take a second to google it rather than bother taking shots at a review for your own shortcomings.
Don't buy any of them, buy a Ridgid.
Thankyou
