I've had dust collection in my shop since I my power tool days. With my small shop, I built a shed next to my shop and where I placed my dust collection so that dust in the shop was not a big issue.
Originally, I had piped dust collection around my shop to all my power tools (table saw, planer, etc.). When I made the move to hand tools though, I wanted some of my wall space back for tool storage and such. With that in mind, I simplified the piping inside my shop by keeping a floor sweep and a separate branch to connect to my one dusty power tool (thickness planer). The secondary branch is just some flexible hose which can stretch to the other end of the shop if necessary. I can easily close off a branch with manual blast gates.
For the actual dust collector, I had a very small 1HP/110v dual bag dust collector originally. I replaced that shortly after I got it thanks to a friend selling me his older 2HP/220v dual bag system at a deal of a price. I think I've had that system running for 10 years. Emptying out the bag was always a chore. The biggest reason is that the dust collector is in a shed, which I hardly ever look at so it was almost always overflowing when I finally got around to emptying it.
I decided to save up and replace it with a small cyclone system. A bunch of years ago, a friend added a European multi machine and added a large Onieda cyclone system (similar to a system I remember Marc/The Wood Whisperer installing when he set up his current shop). My choice in systems needed to be smaller and so when Woodcrafted had a sale, I jumped at it and got the Laguna Mobile cyclone system.
I noticed much best suction right away. Also, the container for the bulk of the dust is smaller so i should be able to develop a routine timeframe to empty the system. The can even has a little view port so I can see if I've over done it or not.
