Stuart spotted the Flex VCE HEPA Vacuum on sale in June, and arranged for ToolGuyd to purchase one for me to vet and review. Since then it has become my primary (and secondary) vacuum solution.
The Flex HEPA vac has been a strong performer and will be on sale again for Black Friday, making it a good time to potentially pick up one of these highly recommended machines.

Flex HEPA Vac Specs
To recap previous posts, the Flex VCE is a HEPA vacuum that is available in two sizes with 9 and 12 gallon capacities. For this price range it has impressive specs:
- 11A motor
- HEPA filtration (class L)
- Dry and wet pickup
- Manual on/off and “automatic” mode switch
- Automatic filter cleaning system
- Adjustable suction flow rate
- Electronic liquid level control (for wet pickup)
- Soft start
- 15 second overrun/run-on feature empties dust and debris from vacuum hose prior to shutdown
- Dust-protected anti-static finish prevents electric charging of the suction hose
- Large rear wheels and swivel casters in front
- 158 CFM max
- 25 ft power cord
- 1.25″ x 13′ hose
Flex Vac Power and Suction Controls
On the front, there are two controls. The large knob turns 90-degrees right to turn the vac on, or to the left to enable automatic mode. In automatic mode, you can plug a corded power tool directly into the Flex’s auxiliary port, and when that tool powers up, the vacuum turns. This is most commonly used with handheld power tool, such as a sander.
The smaller dial allows you adjust the suction power. (Features like this are what separate dust extractors from shop vacuums.)
Anti-Static Hose
The Flex comes with a 15 foot anti-static hose. I must say – I really like the dark red color. The hose feels sturdy, but is still flexible and easily managed. I have accidentally stepped on it and it bounced right back into shape.

The connector at the end of the hose uncovers an interesting detail – it’s identical to the connector on Festool’ hose. When I posted this image on Instagram, I was informed that Nilfisk makes parts for both Flex and Festool. Whether this means you’re getting a Festool quality hose (without the fancy fabric wrap) for the fraction of the cost of a Festool hose is unclear.
Class H HEPA Filter
Inside the Flex there’s a sealed orange filter, which clearly says Class H…. This brings up a complicated topic, is this really a Class H HEPA vacuum?
Based on my understanding, the answer is no. To be certified it’s not just a matter of having the right filter, there are other requirements. One of those requirements is a flow rate alarm that alerts you when the suction drops, such as due to a blockage or full bag. This Flex vac does not have one of these alarms.
However, what it does mean is you get a machine fitted with a 99.97% @ .3 micron HEPA filter.
There is also a removable pleated filter that is accessible from the outside.
There is also an air intake filter on the right hand side.
Dust Bags
The Flex ships with a fleece filter bag and one disposable plastic filter. The fleece bag has a really high quality feel to it and it does a great job of containing the dust and keeping the filters clean.
Auto-Cleaning Mechanism
A feature that is now common on vacuums and dust extractors like this is an auto-cleaning system. This typically works by reversing the direction of the suction so a blast of air can dislodge anything that has built up on the filter.
The Flex’s auto-clean is very noticeable! In fact, a number of ToolGuyd readers have commented how violent it is and I don’t disagree. When it engages there’s a loud noise and the filter cover noticeably strains to stay in place.
Festool and Bosch Tool Box “Gear Loft”
One of the most compelling features for me is the optional Gear Loft bracket. These allows you to mount either a Festool Systainer or a Bosch L-Boxx right on top of the vacuum. I purchased the Systainer dock and it took just 5 minutes to install. I love being able to store vacuum accessories exactly where they are needed.
Finding this part (#6116712) is a little challenging. I purchased mine from Acme Tools, they call it the L-Boxx Holder but I am successfully using it with Systainers.
Compared to the Dewalt DCV012
I purchased a Dewalt DWV012 several years ago and it’s been my primary shop vacuum. When compared to the Flex, I found the suction on both vacs to be basically identical. The Flex is rated at 158CFM and the Dewalt at 155CFM, and so I wasn’t expecting to see any difference.
In terms of noise, at full suction I was unable to notice any difference, but the Flex did sound a little quieter when the suction was turned down. This might not be a fair comparison given all the factors that could be involved but it’s safe to say it’s comparable.
The Flex is smaller, even when you take into account that we’re comparing 9-gallon to 12-gallon capacity. However, the wider wheel base of the Dewalt and the overall chunkiness lead me to say that it would stand up to a lot more abuse making it more suited for jobsite usage, compared to strictly workshop use.
I have always liked Dewalt’s telescopic handle, which makes it easier to move around. The Flex doesn’t have a handle, which means I end up dragging it around with the hose. You can buy one for $54 but at that price you’re going to think twice before buying it. However, the Flex does have the ability to mount a Systainer which for me is a big plus.
Ignoring the price it would be hard to pick between them. For me the decision would come down to what type of environment they will be used in. The Dewalt looks to be more robust and better suited for changing and demanding jobsite conditions. But when you factor in the price difference, you can buy almost two of the 9-gallon Flex vacuums for the cost of just one Dewalt 12-gallon vac.
Final Thoughts
You can find endless discussions online about shop vacuums vs. HEPA vacuums vs. dust collectors, and the pro/cons for different usage scenarios. It’s certainly true that in a perfect world and in a fully equipped shop, armed with an unlimited budget, and unimpeded without any space constraints, you’d have go with combination of dust management tools.
I don’t have that option, and I’m not expecting the Flex to suck up a 100% of the debris in every situation. My real world experience says this is a very competent device:
When used with my Festool sander, I had to turn down the suction because it was sucking itself to the plywood I was sanding. At first I thought the paper needed changing because I didn’t see any dust build up but I was wrong. The combination of the Flex and Festool ETS 125 is honestly outstanding at managing the dust.
Stuart’s Note: This does happen. There is such a thing as too much vacuum power. There are nozzle attachments that let you bleed off some suction power, but variable suction power control is more efficient.
Performance with a Festool track saw was on par as with my Dewalt ShopVac. Heavy particles are ejected to one side, but the cutting area stays nice and clean. I have never tried a Festool dust extractor, and soI don’t know if results would be different.
Stuart’s Note: For some tools, such as track saws, a wider hose diameter has an easier time with larger chips and debris.
At the extreme end, cutting 1/2″ ApplePly plywood on my Dewalt DWE7491RS table saw has similar results, where I end up with a pile of sawdust under the saw, but I at least don’t see a big dust cloud.
My kids used the Flex to vacuum the inside of our cars and it did a very competent job. Given that Flex has roots in the automotive detailing industry, this is hardly surprising.
What this says to me is the Flex is doing an excellent job picking up the small particles. This means my working area stays clean, the air is visibly cleaner but I do need to clean the floor up after I finish a project.
To sum it up, I’ve been really impressed with quality and performance of the Flex. So much so that I purchased a second when the price recently reduced to $239 and I sold my Dewalt! I have one permanently attached to my Dust Deputy separator and use the second for more mobile tasks. I am planning to modify my Dust Deputy so I can run both through it, giving me double the suction for my Router Table.
If you are in the market for a shop vacuum that would be used in connection with handheld power tools or small woodworking machines, you might want to seriously consider Flex’s HEPA vac.

I purchased one from the summer Acme deal you posted and never looked back. It is my go to vacuum in any situation. Article is spot on with my feelings on it. Honestly don’t mind dragging it everywhere as long as I get a chance to use it lol.
MT_Noob
So if there is an adapter for the systainer, then I wonder if the dust deputy cyclone seperator for festool vacs would fit on it.
Ben V
I see no reason that it wouldn’t work! Spending more on the dust cyclone than the vacuum would be an unusual setup 🙂
MT_Noob
I already have the cyclone that I bough previously for my Festool Mini. However, it does not fit the mini all that well, and I am not overwhelmed with the mini, it may just be showing its age.
Is the only difference between the 9 and 12 gallon the size of the bags/capacity? Is the head/motor/suction otherwise the same?
Joseph
Between the sizes, the only difference in the specs is weight. The 42L model is ~5lbs heavier, IIRC. The consumables are identical.
AC
I have the Nilfisk version of this vacuum and paid about $600 a year ago. Worth every penny. This is the deal of the year.
Tom D
TylerTool has matched CPO and dang if their websites aren’t identical in mobile.
Joseph
Tyler is owned by CPO.
Waylon
How would this compare to the Dustless Technologies D1603 vacuum? I was looking to purchase it mainly for drywall dust collection with a Porter Cable drywall sander.
Matt
This has entered impulse buy territory. But I’m passing on it. Having owned a Festool CT 26 for 2 years there’s really two deal breakers for me: no Bluetooth and the autoclean feature. If there were a switch to turn off the autoclean I’d probably jump on this. But if you’re using the fleece bag you don’t need filter cleaning. When Bluetooth came out for the Festool vacs I didn’t think it’d be that big of a deal. But since adding it to mine last year it’s so nice to be able to just press a button on the end of the hose without going back to the vac and going from auto to manual, go vacuum whatever, then go back to auto. I know this sounds lazy but when you’re swapping between tools and vacuuming constantly during a project it’s pretty big.
MattF
The autoclean can select autoclean not to be on. There are 4 setting on the on switch.
I haven’t looked, but if you found something with a remote that had some current draw you could plug it into the auto start, that would work.
Matt
Thanks I didn’t realize you could turn the auto clean off
Ben V
Me neither, thanks for the pointer!
Rick
These guys have all fittings for the vac: https://www.centecsystems.com/home-shop-vacuums/
Good prices; awesome help!
Nilfisk dust bags fit inside. Best price I’ve found is from these guys: https://www.dustdeal.com/
Even tho they are international, they are still affordable; very helpful, too.

Thank you, Rick! I just got my Flex vac, and was dealing with how to hook it up to some of my tools. It looks like this website will be a good start, and very good prices and shipping.
Just curious if you are the Rick who used to post on the track saw forum about Nilfisk vacuums. That’s where I first got the idea that I wanted one. Too expensive, until this deal came up for a similar machine.
Rick
Yes, ktash, I am the Rick who used to post on the tracksaw forum.
ktash
Since that forum is closed, just wanted to thank you. You were the contributor I learned the most from. I’m loving this vac (!!) and wouldn’t have bought it had you not recommended Nilfisk so clearly several years ago. It’s been on my list ever since then.
Rick
Thank you! Yes, I miss that forum; loads of great folks who taught me much….
Bob
Ben, the hose end connector you have pictured looks nothing like the one that came with my unit. My unit came with the following hose https://www.flex-tools.com/en/products/sh-c-32x4m-asnl-2/. Did you change yours?
Ben V
Sorry for the confusion. The photo is of the vacuum end. The tool end is the the same as the link you provided.
I have a reasonable investment in Dewalt adapters so I removed the Flex connectors and replaced them with Dewalt ones. The hose is the same diameter.
Ben
MattF
Hrm, do I need a second one?…
CPO has some very good deals on flex tools. The giraffe sander is about half off.
MattF
Ben, I am confused by the hose fitting you show. I have pulled min apart, but mine looks like this:
https://www.cpooutlets.com/flex-406716-vacuum-hose-adapter-for-ge-5/flzn406716.html
It has a vacuum relief and clip to go to tool adapters.
I also am mostly using a 36mm Bosch hose, which is a significant improvement if you need to do any cleanup and is too much bulkier.
Ben V

Links for the 12 gallon seem to be broken? Also, couple questions if anyone knows:
Does the 12 Gallon from CPO include the vacuum hose? Seems to indicate it does not?
This is the Class L machine, I know the article mentions with the class H filter this is a grey area. I’d like to use this for sanding drywall. I’m EXTREMELY allergic to drywall dust so this is a situation where I’d like to know if spending the extra for the class H rated unit is worth the additional cost? I tried to research the differences on the flex website but all of their product pages seem to be broken.
Stuart
Thanks! Sorry, *fixed*.
I’m sorry, I don’t know how to answer your question about using it for drywall.
Other brands, such as Festool, are much more accessible for user questions.
Zach
What do you guys use to connect the vacuum to your tools? I bought this during the summer sale and have had a hard time connecting it to my job site table saw and other power tools because the included adapter doesn’t fit. Ive ended up having to duct tape to the dust ports with little success.
Stuart
I tried to look up adapter info for the previous post. https://14cyiuhvcgv.com/epic-flex-hepa-dust-vac-deal-continues-062019/#comment-1241082%3C/a%3E%3C/p%3E

Thank you for the post, Ben! I was very tempted last summer but didn’t get it. So this time my mind was made up, and I got it. I’ve wanted a Nilfisk in the past but they were way out of my price range. I’ve only had shop vacs in the past so having a high tech dust extractor will be great. I am especially excited about having the plug-in for power tools. I hope it fits my stacking dust deputy rolling stand. What I have now is a very different shape. I’ll just build something else if I need to. But that’s it for me with Black Friday. I could’ve bought a bunch of small things, but I have enough of those. Who needs a Wera ratcheting screwdriver when you already have a Kobalt ? Waiting for the delivery with great anticipation!! May have to re-organize my whole shop.
Alex
Looks like 12 gallon is back to $399 on CPO
ktash
Ben, I’m mainly going to be using this with a cyclone. With my current shop vac the bag never get filled up. If you’re using yours with a cyclone do you find the need to replace the bags?
Ben V
I used my Dewalt with my cyclone for 9 months, emptying my 20-gallon drum 3 times. The bag was practically empty.
I would expect a similar result with the Flex.
Ben
ktash
Thanks, Ben. I think I’ll wait on getting extra bags.
Russell G.
12 Gallon is $180 on both sites
MattF
Well now I get to explain to my wife why I need three “shop vacs.”
AllanJ
The 12 gallon does come with a 4 meter hose same as the 9 gallon. Unbelievable price today.
Rod Wolfy
Sorry I missed that one!
ktash
Just found the page with all the attachments for the vacuum. Not sure where the dealer is in the U.S. I’m going to try the Centec attachments from Rick’s post first, very reasonably priced.
Here are the ones from the manufacturer. https://www.flex-tools.com/en/products/l/accessories-2/accessories-for-industrialsafety-vacuum-cleaners-2/
MattF
That is the Flex Europe site and not everything shown makes it to the states unfortunately. There are four hose end adapters from flex I know that are available. The best price I found was actually Lowe’s:
https://www.lowes.com/search?searchTerm=flex&refinement=2079884195
Bosch tools and hose adapter with clip receivers are comparable with the Flex hose fitting.
I have a 36mm Bosch hose I put a Nilfisk hose end on and use the Milwaukee branded floor brush. The larger hose helps a lot with cleanup tasks. I keep the this one with the vac and the 32mm ceiling mounted over my bench.
ktash
Thanks, Matt! Who knew Lowe’s would be the best place? I, too, have a Bosch hose, so I’ll get a Nilfisk end. My floor brush is just random scavenged parts, but I already use it with the Bosch hose. And my new Flex hose is ceiling mounted, too, attached to a cyclone.
ktash
I attached the l-boxx holder to the vac, popped on an L-Boxx 4 and just set the 5-gallon bucket w/cyclone in the L-boxx along with cleaning tools. Seems plenty stable for use in my shop. So, instant setup! It didn’t fit my previous cart, but better than that, with a smaller footprint.
MattF
I like just throwing the bucket in an L-boxx
https://postimg.cc/jDs4XX0g
I’ve got an L-Rack set on mine to fit accessories. I plan to 3d print drawer inserts to locate everything. I am going to use a single l-rack section and build a sealed box on top to mount the separator. Or I might print some latches.
ktash
Sounds great!
Alex
@ktash can you post a picture of this?
Alex
Is this vacuum on sale anywhere right now really want it to hook up to my flex giraffe
Stuart
Not anywhere near the same prices as last year, sorry.
Matt F
Yeah, I was hoping, but not expecting those deals would come back.
CPO had things out of control for awhile with stacked discounts and I bought a LOT of Flex tools. The wet grinder seen here was selling for $102: https://www.acmetools.com/shop/tools/flex-288896?cm_mmc=Google-_-PRODUCTFEED-_-Flex-_-288896&gclid=Cj0KCQiAqo3-BRDoARIsAE5vnaI7P2ykVYM2br2N3hlEXQLBUdpSiuH4coBYMyNXRvBhybPcWDIxwBoaAvrCEALw_wcB
I have only flipped/resold power tools a few times, but that event was worthwhile to fund other purchases (of Flex tools).
Dean K
I know I’m late to the party here, but I was hoping either you or Ben had an idea on how to hook up the Flex hose to a Kapex 120 REB. More specifically, how do I make my 32mm hose attach to the Kapex 36mm. will the Festool Cleantec replacement 36mm hose end work on the 32mm Flex hose? https://www.acmetools.com/shop/tools/festool-500670f
Stuart
It’s hard to say – you might need to contact Flex to see what they say.
From their website, they have an adapter – Coupler bush model 257.169, SAD D32-36 – but it’s hard to say if it’s compatible:
One online forum references the Flex 36mm SAD-C 36 AS 461.636:

Love this vacuum. Picked one up from acme, but most of the accessories are hard to obtain now. Nilfisk manufacturers and private labels them for makita/milwaukee/flex/stihl. The lboxx adapter is NLA from flex but is still available from makita and is the same exact part. I have found the accessories from one brand to another have enough nuances that make them incompatible with each other which is unfortunate.
