Should be noted that this sleeved hose/cord has been discontinued by festool. You can still find them at a few places if look hard enough though. I got rid of all mine because I found them too heavy for everything; and too restrictive for just about everything but sanding. They were a tapered design if I recall correctly.
I have an EC sander for 5” and 6” and I’ll throw in my contrary opinion: I don’t like it as much as the peanut gallery does. Mine has also been in for service because of a blown ecu board - and others have had the same part blow. Nothing like the amount of kapex woes , but enough to have a couple of threads about the issue. It’s not annoying enough for me to sell, but it doesn’t get used that often. Next to carvex, my least favorite festool. Try it in the store and really use it within 30 days - you’ll get a good sense of whether it’s for you or not. If not , return it and get a reg. ETS.
I also have or had just about every premimum tool activated vac down the pipe (and some screamers too). Wap, Fein, Alto, Festo (nilfisk), Porter Cable and Festool. Craftsman, Ridgid, and ShopVac cheapies. I’ve been satisfied with all of them except the craftsman. They all did the jobs intended, but I would not want to sand all day with the ridgid any more than I’d want to use the festool to clean up debris from a tile job.
What Ive learned over the years is that you need to match the vac AND hose to the job. A small , longer hose is preferable for sanding especially if you’re using it to do walls and ceilings. A larger, shorter one is better for large debris cleanup or things like planers. Sometimes a tool will dictate the hose. Some guys like the. 36mm hoses for routers, but you really can’t use that size with an OF1010 or a DeWalt 611. I’ve grown to like the the anti static type hoses that festool and Bosch have. Worth the xtra spend for me.
Some have said there are cheaper alternatives to festool vacs. True. But when you compare apples to apples they really compare favorably. Other vacs may be cheaper but by the time you upgrade to HEPA and get an antiststic hose or longer one, the savings are eroded. That’s before you even start to look at the turbine power. Festool isn’t the best/strongest but it’s right up at the top. And should you ever want to go mobile, they pretty much best everyone with portability and the systainer stacking.
Then there’s the tool triggering. Plug up whatever you want into a festool vac. Plug your mitersaw into a Porter Cable or WAP tool socket and you’re going to be sending in for service and receive a sizable bill for a control board.
