Sebo...
Hey People
In my opinion Sebo make THE BEST upright cleaners on the market today (and their cylinder/cannisters are growing on me as well). I myself have both a X1 and a Felix Fun(I was fortunate enough to get the Felix from work as a staff deal
. Both are excellent machines, although I prefer the Felix for ease of use and also love its orange/purple colour scheme!. Filtration in both is excellent with the Felix again maybe just having the edge.
If I was to buy another new upright, even if it was at the £230 retail it would be another Felix
