I'd like to offer up our praise for the new CT26, and also pass along our thanks to both my dealer  Tom Bellemare and to Christian at Festool.

The CT26 has proven itself to be an incredible machine, and  I'll have a few observations to share in a moment.  But first, allow me to tell you how we ended up with two new CT26's.    

I bought two RTS 400 sanders from Tom, specifically for my men to use to sand plaster and drywall on our jobs. We have ended up using these sanders on other surfaces, but they were originally bought for drywall and plaster, and that is where they get the most use. There are a few other drywall sanders on the market, but I liked what Tom had to say about using the RTS 400, I liked the fact that they were compatible with our existing stable of vacs (CT 22 and Midi's), and I liked the wide variety of abrasives.  That's how we ended up with sanders being used as a plaster and drywall tool.  We eventually ended up having the problems that some others were having-namely the bags blowing apart and making a mess inside the vac.  We had a couple of blowouts, and assumed we had done something wrong.  I then called Tom for advice, and he and I discussed the issue and he ended up sending me some bags and a new HEPA filter to help ease the pain of having to spend so much time cleaning the machines after a bag blew apart.

At some point, I read on this  and similar forums that others that  were having problems, as well.   We were facing a large remodel job, which was going to have a huge amount of drywall and plaster work to deal with, and I called Tom to see if there was any way I could buy a Planex (the answer was "no").   I wasn't sure what to do, and I really didn't want to go and buy a competitor's sander/vac unit, but I knew I couldn't keep using the existing bags in our Midi's and CT22.  It was at this point that Tom went to bat for me and called Christian at Festool.

Christian generously offered to send to me  a supply of the new "pliable fleece filter bags" for my CT Mini, which were supposed to be able to avoid the problems with fine dust,--but these bags were in Germany and couldn't be obtained fast enough to help on our project. Christian then shipped two CT 26's to us to use on our projects, and asked only that we use the tools as much as possible for several months, and to provide feedback to him and his staff in Indiana.

We have had the CT 26's for more than three months now.  From Day One, I told my men to use these vacs for everything and to give them a good workout.  I even told my crew to try and get a bag to explode, because that is exactly the kind of information that  Christian and Festool would like to know.  For a vac that I had paid for, of course I wouldn't want this to happen, but if we were testing something--I didn't feel so bad about it.

The result is that, even though we have sanded acres of drywall and miles of trim, and cut a lot of cement board, concrete block, bricks and other hard materials.....and haven't had a single problem with a filter bag failing/blowing out/ripping/etc.  I've used these vacs with the TS 55 and 75, with the router, with the Rotex and the RAS.  I've ground and cut on  Corian, stone, tile, and cast iron (with the spark trap). It's been used with the Rotex to strip paint and adhesive off of floors.  We've used these CT's as shop vacs, even when the messes were really too much for what the machine should be used for and a broom and dust pan would have been better.

The simple observation is that we haven't been able to get the bags to fail and haven't been able to clog the vac or bog it down.

We recently did a bathroom job in a condo, and there was no room anywhere on site to mix mortar, thinset  or grout other than in the bathroom itself.  We mixed all the drypack mortar and the fat mud for the walls in buckets with a large drill and mortar paddle.  We mixed all the thinset in the room as well.  To control the mess, we used the CT26, running continuously, to suck up all the sand and cement dust while we poured material out of the bags and into buckets  and while we mixed.  I thought that surely we would overheat the machine, or at least kill the filter and have to ask for another one.  The result of all of this was that the fleece bags absorbed all the dust and the HEPA filter looked nearly new.

I could note the various features of the new CT26 which are an improvement over those of the CT22, but that really wasn't the purpose of posting this. I instead wanted to let anyone know who might be on the fence about buying this vac, that this in one tough machine and you will not regret having bought it.    

I of course don't know the conditions under which the members of the FOG use their CT's, but I am pretty certain that in the past three months, we have put these vacs through what many would consider to be a real endurance test, and under conditions which are more extreme than are found in most shops.  If these CT's can handle the rough service on our remodel job sites, they will do well for you, also.

One final example.  

We were behind schedule a bit around New Year's.   I borrowed an employee of a contractor friend of mine and put him to work with our crew.  He started using the CT with the RTS 400. He didn't pay attention to what he was doing, and the CT 26 went tumbling down a flight of steps.  The impact at the bottom broke off a corner of the hose garage.  The guys pulled the vac back upstairs, reattached the sander, and continued to use it for the rest of the day.  It turned out that when the vac went down the stairs, the bag was somehow disengaged from the connection inside the machine.  No one thought to check inside, and so they used the vac for the rest of the day, sanding drywall and plaster. We figured this out the next day when one of the guys looked inside to check the bag, and the machine was .......well. you can just imagine what it looked like in there.  

One of my guys spent about 30 minutes cleaning it, and then put it back together and started using again. It's been running fine ever since.

edited to fix typos.....

 
Nice review Rob.

What grit sandpaper are you using for drywall?
I just taped the drywall in a large room I am remodeling & want to use the RTS 400 when I get ready to sand.

OK, this line grabbed my attention!!!

Are the new CT26-style bags going to be available for the Mini & Midi? Does anyone know anything about these?
 
I also recently switched from the 22 to the 26 and I can't say I regret it. Haven't been able to use it a lot yet but some benefits are quite obvious to me. More suction and less noise. I think the overall noise of the motor is more or less the same, a bit higher pitched on the 26, but the 22 had this extra noise of the plastic casing rattling and that really irritated me. As for the wheel brakes, I thought they sucked on the 22 and the solution of the 26 isn't perfect either. That stop block works great with the Mini, with a bigger vac like the 26 not so.

The 26 is a bit bigger than the 22 without the hose garage though, and that's something you do notice when hauling it around. The 22 was easier to carry around in the house, like up the stairs. But I think the biggest improvement in the 26 lies in the bags. These new bags are a lot better than the old paper ones, both in strength and with clogging.  
 
Great info Rob, thanks for sharing. [thumbs up]  I've had the CT26 for a while and I was a bit weary about really giving it a good hard workout on my remodeling jobs.  Little by little I learned I could really push the new vac well beyond what I would have been comfortable doing with my old CT22 or Mini.  While I generally try not to,  I've sucked up nails a few times with no problems.  I wouldn't say I'm willing to treat the 26 like I would my old beater Shop Vac but I don't have to be nearly as careful about what and how much I such up as I did with the older Festool vacs.  The built in hose garage, increased suction, new brake and other improvements are just very sweat icing on the cake.....

Chris- I use 120 or 180 when I sand drywall.

What sander are you using?

Did you get any snow or ice up your way?

I use my ets 125, or should I say mis-use. [cool]

I normally use my PC drywall sander with 120 or 150 but, sometimes it is not practical to use for a job though.

5" last night with a bunch of drifting.  They say we could get up to 20" this evening though.  I am not sure I believe them though.

Do you have any problems cutting into or roughing up the paper?
 
Not normally with the ETS.

With the big PC, sometimes as I find it awkward to use in certain situations.

Just keep moving and you should be fine.  I will say that if I know I am power sanding, I will use the mud with the most glue in it as it tends to be harder to sand.  Which is either the green lid or black lid, depending where I get it from.

I use a lot of 90 minute when skimming old plaster walls and that stuff is pretty though when it comes to sanding.
 
Thank you Darcy. [big grin]
I use the green lid mud & some 90 minute.
I have always hand sanded. After I sanded the kitchen before Christmas, I decided it would be the last.
I guess I need to put some mud on scraps & try out the sanders.

We got a lot of ice here.
Limbs are coming out of trees & I can not get out of my driveway.
I did not think I was going to be able to get across the driveway to the shop.
More on the way tonight.

Have you sucked up any wet stuff with this?  For example, not quite hardened blobs of thinset, grout or drywall?  I used to do this with my shop vac.  I hated that thing so I gave it away to be eventually replaced with a CT 26.  The thought of gunking up one of the hoses isn't appealing, but the thought of throwing a bag of dirt away instead of dumping a bucket certainly is.
 
Rob:
Brilliant review! I had it on my list but it's good to have my concerns addressed in a "real life" test.
Thanks.
Tim
 
Hi everyone, I haven't been back on since I posted this  (too much work, not much time for the internet).  I'll respond to everyone's questions, and thanks for your interest.
 
Hi Chris,  I'll have to ask the guys tomorrow, but my guess is that they are using 120 and 220.  I buy Brilliant for drywall and plaster.  I know having the guys use the RTS 400 has gotten several jobs for us, because they have been sanding drywall in occupied rooms (bedrooms, kitchens, etc) and with no dust getting away...the owners are amazed and start thinking of other work they want done and have been avoiding because they dreaded the mess.

Hi Jonny, let's hope my dealer Tom Bellemare steps in here to answer about the availability of the bags.  I got my initial stash of the bags, courtesy of Christian. I'm about to run out, and will have to call Tom to find out what the deal is with ordering more.

You will love these new bags.

Hi Alex, I told Christian that I couldn't give an accurate comparison of the noise of the 22  versus the 26 because our 22 has gotten so much use.  It seems to me that the CT26 is smoother, but it might be just that my CT22 is plenty worn-out.  I don't know about this.....

I did like the built-in hose garage on the CT26, except now that the one unit got sent down the stairs and the corner broke off----there's no good way to repair it.

Hi Brice, you will appreciate this one...we just finished installing a bunch of doors in a condo, and then we were  using the Templaco brand jigs for the hardware.  You know what kind of heavy shavings come off of the 850 planer, and the large curly shavings that come from a lock boring jig. We were working inside the bedrooms, with our door bench set up and the CT26 sucking it all up and leaving virtually no mess.  This was a job where it was three flights of steps down to a busy street, so even if we wanted to run up and down the stairs with a bunch of heavy doors (we didn't), there was no secure place to set up outside anyway.  At no time did we bog the the CT26 down with the largest of shavings.

Like you, we have hit nails and screws, and now I'm actually a bit careless about it...nothing has happened to the bags.

Hi Kodi,  yes, we have...enough so that some of the hoses and the tools in various cleaning kits have some "deposits" of thinset on them.  But we haven't tried to clean up large amounts of plaster, thinset etc, just errant globs that are mixed in with other trash and mess.
