Our Verdict

Miele Complete C3 Alize

Miele Guard S1 Electro

The Miele Guard S1 Electro is a much better vacuum for carpet than the Miele Complete C3 Alize it replaces, thanks to its powered brushroll, which is more effective than the Alize's straight-suction floorhead. These vacuums both perform about the same on bare floors, with each having issues with large debris. Aside from that, the Guard S1 has a shorter power cord and four suction power levels versus the C3's six, so it may be a little less convenient to use.
