Do Festool CTC-SYS batteries last long enough?

The new Festool CTMC SYS cordless dust extractor. Do the batteries last long enough or do they leave you wanting more ? Do the batteries charge fast enough ? Can you use the extractor all day on 4 batteries ?

Roughcutprince , you are good at this!! Delightful adhoc setups & clear explanations. Reminds me of the content creator at Projectfarm. I was puzzled as to why you only have only 260 subs with such polished videos & then I saw you only post now & then & it made sense. Post more often like once a month if you have something to share & I’ll sub!! Cheers from California.

Hi and thanks for the kind words. You are spot on. The time I could spend on the channel got seriously derailed for a while. Frustrating all round. I’ve pretty much sorted it out now so should be able to start putting out at least 1 video a month from next month and aim to do 2 a month from January. Hope you’ll find them interesting.

I had similar readings on a test , I will be using this set in short bursts in multi areas of snagging on buildings. I have the larger midi corded 240v version for proper sanding and biger jobs.. nice vid..

@hovermotion thanks

[@ManCaveWoodworking]

Thanks for making the video, as somebody who uses Festool gear day in and day out this was just the info I was looking for!

[@roughcutprince]

Thanks Andy. Glad it helped. Now I understand the products better, I'm really pleased with them.

[@jason-hh6lu]

Have you got the Festool app? It tells you the % of the battery and other info when a Bluetooth battery is connected to your phone and the app. 👍🏻 nice video

[@roughcutprince]

Thanks Jason. Appreciated. I do. It’s a good app for things like battery firmware updating, but when it comes to battery charge numbers it has to just report whatever the battery says. It has no other way of knowing.

[@josephKEOarthur]

I absolutely dont understand why they dont have an wall plug in adapter.

This is really good review. Thank you.

I'm very curious, was this test run with the included 27mm hose connected? Or was the vac's intake port open with no hose connected? I have a sneaking suspicion that the included hose is so restrictive that it's actually impacting the vac's efficiency & reducing run time. Would love to see this test done with different hoses, or even just hose vs. no hose attached.

[@roughcutprince]

I ran the tests with the included 27mm hose because its an M class model and the Festool manual states that the volumetric flow monitoring is calibrated only for the supplied hose. So I ran the tests on the basis that that is the hose people would use it with. Interesting thought, though. The end of a 36mm hose is the same 57mm diameter, so it will fit the outlet. I’ll try running the tests with a 36mm hose attached and see what it does to the results.

[@MobiusGuitars]

@@roughcutprince Excellent! That's the setup I'm most curious about. Just yesterday I ran an air speed test between the 27mm & 36mm hose on my corded CT SYS. The difference was quite remarkable, going from 5.5 m/s up to 8.5 m/s. The vac's exhaust temp was also notably cooler, indicating it's running more effeciently. I do not yet have a CTC, but your test could be the determining factor!

[@normanmann7404]

You can take a look in the Work App to see the actual state of charge for a Bluetooth battery

[@roughcutprince]

Hi Norman thanks. I’ll look into that

[@ThisTall]

I’ve gone cordless everything in the last 5 years and it’s really not worth it. In my opinion it’s much better to leave all medium-large tools corded and use portable power banks. Even multiple power banks if needed.

[@carbb5760]

Ya I took mine back yesterday, a single charge wouldn’t even handle the smallest job I would ever go do without needing to replace the batteries. This is a failed product imo and should never have been released. I ran a similar test and got around 9 minutes on high with my fully charged batteries with a significant suction drop around 7min.

[@roughcutprince]

@carbb did the suction drop happen at the same time as it beeped twice?

[@carbb5760]

@@roughcutprince I noticed it before the beep. Maybe I could have made it work for me but just felt like it was not good enough

[@WhangaFish]

Mind if I ask what job you were doin at the time?

[@carbb5760]

@@WhangaFish I was prepping 2 holes in drywall for my electrician to run wiring for an EV charger a customer of mine was having us install. So cutting connected to my osc tool and doing a very small cleanup.

My Bosch runs about same time with one battery

[@roughcutprince]

Hi. Yeah, it is the one area Festool haven’t improved. I have used the Bosch for the last 3 years and it had been good, but as I mentioned in my CTC SYS review video, I found the Bosch wasn’t really designed for fine dust like brick or MDF dust as it was only an L class and had no bag for the drum. The filter got especially caked and was really messy to clean. The Festool is much better in that respect and as that was my no. 1 issue, I find I now only use the Bosch for general cleanup of non-fine dust. If only the Festool could take the 5.2 ah batteries, but it can’t.

[@ElDrKaiser]

I got this sander. It looks nice and it’s powerful. But the run time is pathetic. I got like 6 minutes on low with fully charged batteries. I’m returning this crap.

[@roughcutprince]

The run time is the biggest weakness, but 6 minutes is really short. I'm curious - were you using 3.1 ah batteries or 4 ah?

[@ElDrKaiser]

@@roughcutprince i was using the 4ah. I had to buy the impact set to get the batteries. Which by the way also sucks. Makita makes better vacs and impacts.

[@ryane6719]

@@ElDrKaiser The cordless Makita vacuums are awesome, we get about 45 minutes of run time with the twin battery system. And that’s actual heavy use.

[@roughcutprince]

@ryane are those m-class?

[@ryane6719]

@@roughcutprince I looked on Makita‘s website and at least for the US website they don’t seem to share this info. These are the two models we’ve been using regularly at work sites.. XCV21ZX GCV04ZUX (this model is easily as powerful as some of our corded festool vacuums)
