My profile pic, Proline UVC 18 is the best upright IO used, well second best cus the features are crap lol, Dyson DC14, DC04, DC14 and DC27 + DC33 All the way!
The proline I regret throwing out

I snmashed it, proper durable tho

It had mad suction
I had the blue bagged cylinder, hose end didnt clip well, crevice tool holder broke, Filter didnt do well, floor tool broke, and motor kept going out of place!
Second one my Auntie gave me cus she was moving house and got a Henry, I cant get rid of it cus Aunt paid £30 for it and happily gave it to me, Which is really nice, BUT...
Bin keeps falling off
Use the vacuum for approx half an hour, turn it off, turn it on on low power, sounds like it runs on batteries which are gonna die
Floor tool cracked
Hose end cuff keeps getting un screwed, Filters ripped, And now it cut out on me!!!

It wont die but annoyed me so much, its in the shed now, gonna stay there for a while
Lesson:- Argos vacuums, cylinder or upright, both have good suction, but the cylinders are cheapo!!! uprights are descent but rubbish design
