Miele Complete C3 Cat & Dog vs Guard L1 Electro

The Miele Guard L1 Electro is the successor to the Miele Complete C3 lineup, which includes the Miele Complete C3 Cat & Dog. If you're upgrading from the C3, the L1's biggest advantages are cleaner air and stronger suction, but you won't see a dramatic leap in cleaning performance on most surfaces. The L1's HEPA filter delivers far better particle filtration than the C3's Active AirClean filter, making it a much stronger choice if allergies are a concern. On the other hand, the C3 edges ahead on low-pile carpet pickup and does a much better job clearing pet hair from upholstered furniture.
