I  sure love my  16 gallons  Shop-Vac Ultra    with blower port  and drain plug.  

I  have taken  3   8 foot  hose   and  put them together   to form a 24 foot   aprox   long central  lenght   hose   2-1/2 inch  . I  use   a  bag and  cartridge filter so the thank  stays   clean   ,  i do  hose it down after a wet pick up   makes  big job a  breaze as well cleaning cars back in the day for the lonng h ose  love it   . As  well  for DYI   .

I had a Festool CT33

It was great but the cost of bags, filters was ridiculous.

What made it worse is that unlike other festool power tools their is nothing really special about the festool that you can't get on a different High quality vacuum at a quarter of the price,
Take a compound Mitre saw, If you need to do intricate  work, Ie really high end furniture or where your costs have to be 100% true, there is nothing , absolutely nothing on the market that is as good as a festool, Some come close but festool is just superior in every way so it makes sense to spend the extra to get it, especially of you are a high end carpenter.

Its also worth noting that often the vacuum is given at no cost with purchases of mitre saws and the like.

The thing is that if you want a dust extraction system for your woodwork tools then you can get away with a lot cheaper and same quality as the festool.

a wap attix 3 had the same motor and you could order it with the auto on off for the tools, if you went to the attix 5 at the time you could get that with the auto clean function which would clean its own filter, meaning you never had to use bags ( their ones were a lot cheaper too)
the waps or even a Karcher had much bigger capacities than the festool too.

Its worth noting that unlike household cleaning Vacuum bags are a disaster in the woodworking industry, if hooked up the my mitre saw or hand planer I could fill 2 or 3 bags a day on a festool , if hooked up to the sander the fine dust would clogg the bag in minutes and you would have to open the machine and shake the bag to loosen the dust from its sides .
it's worth noting that Festool vacuums bags cost about $ 45.00 for 5 and you will use them fast.

It's not a bad machine there are ust allot better and less costly options out their.

Oddly enough as far as my woodwork goes, my huge rigid is my favorite, massive airflow from its single fan motor and a bin thats huge, yes its a cheap machine but oddly enough it works great. I just need to fit auto on and off to it with a plug outlet

I am not saying the festool is bad, it isnt , if it were better priced then I am sure I would be far keener on it than I am. 

My issue came in when doing some research and when I still owned my festool, (I traded it for a really awesome table saw ) I looked at other models on the market, two that came up were a Karcher and a Wap alto. both had the auto on and off, both had the exact same motor as the festool but both had biger drum and better filtration, what made it worse was that both the machines cost half the price of the Festool, meaning I could buy 2 for the price of one festool, as you know in a wood work shop two are always better than one. The only advantage the festool had over them was its storage facility on top of the unit  which is nice for mounting a separator tank, but I can easlit make a trolly myself.

Often I think that festool gets given the best results because its festool,

and yes a domino is just amazing
