Main trade-off
Miele Guard M1 Cat & Dog
The included upholstery nozzle has no rotating brush.
Head-to-head
The Guard M1 Cat & Dog is the stronger starting point if you want more bag volume with the same air-driven rug brush and reach. Choose the L1 Cat & Dog if its plus and minus foot controls and combined upholstery/crevice tool suit your routine. The L1 name does not buy an electric carpet head in this package.
Before you choose
For short-pile rugs, these packages start with the same STB305-3 head. The meaningful differences are bag volume, controls and tool storage. There is no matched evidence that the L1 removes more pet hair because of its series name.
What this is based on
Both official package lists include STB305-3, AllTeQ and Active AirClean. M1 and L1 have different body-control and bag arrangements.
Main trade-off
The included upholstery nozzle has no rotating brush.
Main trade-off
An air-driven floorhead is included, not the electric head supplied with the blue Guard L1.


Miele Guard M1 Cat & Dog vs Guard L1 Cat & Dog: compare bag volume, foot controls and upholstery tools. Both include the same air-driven rug brush.
Look past the series names. The same rug brush sits on two bodies with different bag volumes and suction-control layouts.
Winner by situation
M1 has more nominal bag room, with the same included floorhead.
L1 gives separate plus and minus foot buttons rather than cycling the M1's four modes.
Neither box includes a hand turbo. The plain nozzle design changes, not the brush capability.
Both use the same air-driven STB305-3. The blue Guard L1 is the separate electric-head package.
Both publish the same cord length and operating radius.
What matters in practice
For short-pile rugs, these packages start with the same STB305-3 head. The meaningful differences are bag volume, controls and tool storage. There is no matched evidence that the L1 removes more pet hair because of its series name.
Both official package lists include STB305-3, AllTeQ and Active AirClean. M1 and L1 have different body-control and bag arrangements.
A 4.5 L bag versus 3.5 L gives M1 about 29 percent more nominal volume, while both still offer a 36 ft radius. That supports choosing M1 when collection volume matters, but cannot promise 29 percent fewer bag changes.
(4.5 / 3.5 - 1) x 100 is about 28.6 percent. Both manufacturers' US product pages list 36 ft operating radii.
L1 combines the upholstery and crevice functions into one tool. That can simplify moving between cushions and gaps, but both packages still lack a rotating handheld brush for fabric hair. Budget for that separately if it is the main task.
M1 lists separate upholstery and crevice nozzles. L1 lists a two-in-one nozzle. Neither package lists STB101.

Miele, 12704670
A long-reach bagged model for hard floors and short-pile pet rugs. Its air turbo floor brush should not be confused with an electric carpet head or a small sofa brush.

Miele, 12704570
A foot-controlled bagged canister for hard floors and short-pile pet rugs. The Cat & Dog package supplies a floor turbo brush, while sofa cleaning uses the plain upholstery attachment.
Meaningful differences
| What changes | Miele Guard M1 Cat & Dog | Miele Guard L1 Cat & Dog | Why it matters |
|---|---|---|---|
| Rug brush | Air-driven STB 305-3 | Air-driven STB 305-3 | No electric carpet-head upgrade comes with this change of body. |
| Bag volume | 4.5 L CO | 3.5 L TU | M1 offers 1 L more stated volume, about 29 percent more relative to L1. |
| Suction control | Mode button cycles four levels | Plus and minus foot buttons | Decide which adjustment method is easier for your cleaning route. |
| Small tools | Separate upholstery and crevice nozzles | Two-in-one upholstery/crevice nozzle | L1 combines two functions rather than adding a rotating sofa brush. |
| Charcoal filtration | Active AirClean | Active AirClean | The filter name is shared. It does not establish a measured odor-removal winner. |
| Reach | 24 ft cord, 36 ft radius | 24 ft cord, 36 ft radius | The step to L1 does not extend the published cleaning route. |
What you give up
Recommendation switch
Choose Miele Guard M1 Cat & Dog. M1 keeps the same floorhead and reach with an extra liter of stated bag space.
Choose Miele Guard L1 Cat & Dog. The L1 foot controls address that workflow, without implying stronger carpet pickup.
What matters in practice
Start with M1 Cat & Dog for its larger bag. Choose L1 Cat & Dog when the foot-control layout and combined small tool justify giving up bag volume.
Picture a route from rug to curtains to cushions. M1 cycles through its suction levels with a Mode button. L1 uses plus and minus foot buttons. The useful distinction is how often you change settings and whether you prefer stepping directly up or down. Neither control layout makes the shared turbo head an electric brush.
Both packages are bagged, but their consumables are different. M1 uses CO bags and L1 uses TU bags. A stock of bags for one does not become a saving on the other. Compare the correct replacements and the storage routine alongside the 4.5 L versus 3.5 L volumes, without assuming a fixed number of weeks between changes.
