I had one, the CX1 Comfort
Very quiet
Very powerful, mine has the ecotec straight suction head and it stuck to the floor nicely and actually groomed since the head kinda dug into the floor with the sealed soleplate design
The cyclone was rubbish
The pre motor filter is a pleated one which has a large surface area, it's not bad and you can actually get another vacuum and fit a crevice tool in between the pleats which is good, can also be washed and tappedout. Not a bad filter
The filter compartment is black and it's all fine dust that collects in there so you;d need to scrub that if you want it spotless, just a rinse win't get it fully clean
Long hair and thread got wrapped around the tiny cyclone
Any bigger bits that get sucked up just swirl around the cyclone area, smaller bits are meant to be spun out and fall into the bin
It's large,but it has a parking bracket underneath and on the side which is nice
Has a remote control which is awesome (handle controls I mean)
It's a solid machine, but the cyclone and bin area has some weak plastic areas
The wheels were kinda springy (the four castors underneath)
It's overall not bad, it's just the cyclone and filter area which is my main pet peeve with it.
