I don't think I've ever seen a Sebo in a pub. It's all Henry's round here, with a few Dysons thrown in.
There is a white X1.1 used in a bookies that I walk past on my way home from work and an x4 in the conservative club down the road from where I live. My local corner shop has one too.
The first Sebo I saw was the later all white x1. A friend of mine from school's parents had a working farm (which is now a riding school). They originally had a Vax 2100 and a Turbomaster, but the TM died in about 98 (ish) and was replaced with a Sebo X1.
In 1998, most people I knew were using Turbopower 1's, Lux Twin Turbo's, Contours, DC01's etc. All the usual late 80's and early 90's vacs you'd expect to see around. A lot of Vax's too. So when I walked in and saw the Sebo box in the hallway, I was incredibly intrigued. I don't think I'd ever heard of them before that, although I do remember seeing a few 360's around but not really paying much attention to them. I got to use it in their living room and was instantly impressed. I've had a bit of a love affair going on ever since lol.
It's still in use, although it's now the upstairs vac as they bought an X4 Pet about 18 months ago for the main areas.
