I put it in our house and absolutely love it. If the piping is all in place and the inlets are in the walls it is a real easy drop in installation that would take an average skill level do-it yourselfer about an hour.
The main unit connects to the piping with flexible couplers and worm clamps, the wires from the inlets need to be crimped with connecters and attached and the unit needs to be plugged in.
If you have to run all the pipes and put in the inlets it's a bit bigger job but not that hard. Easily done in an afternoon if planned well. If you do use the sweeping 90's rather than the tighter ones to avoid blockages.
I have hardwood throughout so I mainly use the hardwood attachment, But I have the powerhead for area rugs and the dustpan under the counter kick.
BTW, Dyson makes a CV. (NM, I thought I had seen one but it might have been the cannister style.

)
Downside is the hoses don't last forever, at least the stock one didn't. It didn't swivel well and tore eventually, but the aftermarket one we bought is rapairable and seems swivel better. You need to monitor the tank and clean it more often than they recommend (it has lights to indicate how full it is). My first unit failed as dust got into the motor, but I use the hepa filter now and no problems.
