You love your Dyson, I love my Felix.
The Felix isn't really a baby vac - that's only considered if you lower the handle to the lowest 3 point height setting! It has a 3.5 litre dirt capacity and high filter dust bags. It was designed to act as a medium home vac. The ET-1 floor head is extremely durable but then there are others on here who report that the floor head cuts out on thick pile. I've never had that problem because when I considered the Felix my home had been installed with medium pile wool carpeting; a Dyson would effectively destroy the strands very easily and the Felix brush roll compensates for brush wear and carpet due to its design with an additional soft roller brush available. It has a removable brush roll as opposed to Dyson and comes out via a side partition.
SEBO's vacuums are commercially based, so they're not like your domestic Dyson. I don't dislike Dyson but I know from experience that they can break down easily due to the plastics plus you have all that noise to contend with. The Felix is pretty quiet for its low energy, eco friendly 1300 watt motor and has a variable suction slider on the handle.
As for suction, the Felix has plenty of it, both with the older paper bags and high filter bags, though the latter bags seem to prolong suction better just when the bag needs replaced. It does well on hard flooring too, not just due to the brush roll on/off on the ET-1 power nozzle floor head, but also for the fact that as standard, the Felix comes with a deluxe parquet hard floor static brush tool too.
