175 watt does seem a lot for a brush bar motor, but those powerheads really do pack a punch. They don't slow down even on plush pile carpeting, and as you know, they pull the vacuum forward quite noticeably. What I think would be quite interesting, although it probably wont happen, is if SEBO use Numatic new 580 watt motor, which Numatic say has 10% more suction power that even the previous 1200 watt model. That in a Felix or sebo upright would be very interesting. Its not exactly as if they previous Henry motor was lacking in power as well. I know that SEBO and Numatic are tied up in some way, with Numatic branded vacuums made by Sebo being sold in Germany, think they are the G series Sebos.
