The hose reel is a pain in the backside. The hose is quite rigid and the reel being quite high up makes it more of a hassle than it is worth.
I've got a C110 and had it for 5 or 6 years without a single problem and it will draw from a water butt through a filter if you are that way inclined.
My only suggestion would be to get the 8m hose as the standard 1 is too short and requires you to move the unit around a bit when using it. The longer hose allows you to leave it in 1 place and go from there.
I ordered the E140.3 last year, after recomendation from James or Remyroc detailing.
It's so much better than I had before and is generally higher quality.
It did come with the long hose as standard, so no need to move it during use.
It stays well away from the wet area and snow foam etc.
I know this won't help you but it may help someone else who is after a pressure washer. I bought a C110.3 nilfisk for the father in law through Amazon just before Christmas for £60. Useful for anyone looking.
