Miele Guard M1 Cat & Dog vs Guard L1 Electro

The Miele Guard L1 Electro and Miele Guard M1 Cat & Dog are both premium Guard models, but the biggest difference you'll notice is how they handle pet hair. The L1's powered electrobrush agitates carpet fibers more aggressively than the M1's air-driven turbo brush, so it lifts more hair in fewer passes. The L1 also maneuvers more smoothly around furniture. The M1 makes up for it in everyday practicality: it's lighter and has a larger dirtbag compartment, so you're swapping them out less often, despite the M1's bags having a smaller advertised volume. Air quality and build quality are near-identical, though the M1 uses an activated carbon filter rather than the L1's HEPA filter.
