The catch
Miele Guard M1 Cat & Dog
A rotating brush is missing from the included upholstery nozzle.
Side by side
If more bag volume matters, start with the Guard M1 Cat & Dog, which has 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 get you an electric carpet head in this package.
Before you buy
On short-pile rugs, both packages start from the same STB305-3 head. What differs is bag volume, controls and tool storage. No matched evidence shows the L1 pulling up more pet hair because of its series name.
Where this comes from
STB305-3, AllTeQ and Active AirClean appear on both official package lists. M1 and L1 differ in body controls and bag arrangements.
The catch
A rotating brush is missing from the included upholstery nozzle.
The catch
The included floorhead is air-driven. The electric head belongs to the blue Guard L1 package.

Same air-driven rug brush in both, so Miele Guard M1 Cat & Dog and Guard L1 Cat & Dog come down to bag volume, foot controls and upholstery tools.
Series names aside, the rug brush is the same on two bodies whose bag volumes and suction-control layouts differ.
Which one fits
The included floorhead is the same, and M1 has more nominal bag room.
L1 has separate plus and minus foot buttons. The M1 makes you cycle through its four modes.
A hand turbo is in neither box. What changes is the design of the plain nozzle, and not what the brush can do.
The air-driven STB305-3 is the same on both. For an electric head, you need the separate blue Guard L1 package.
Cord length and operating radius are published as identical for both.
In practice
On short-pile rugs, both packages start from the same STB305-3 head. What differs is bag volume, controls and tool storage. No matched evidence shows the L1 pulling up more pet hair because of its series name.
STB305-3, AllTeQ and Active AirClean appear on both official package lists. M1 and L1 differ in body controls and bag arrangements.
M1's 4.5 L bag, against 3.5 L, adds up to about 29 percent more nominal volume, and both still give a 36 ft radius. That favors M1 when collection volume matters, though it can't promise 29 percent fewer bag changes.
(4.5 / 3.5 - 1) x 100 comes to about 28.6 percent. The US product pages from both manufacturers list 36 ft operating radii.
L1 folds the upholstery and crevice functions into one tool, which can make it easier to move between cushions and gaps. Still, neither package has a rotating handheld brush for fabric hair, so budget for one separately if that is your main task.
Separate upholstery and crevice nozzles are listed for M1, and a two-in-one nozzle for L1. STB101 is listed for neither package.

Miele, 12704670
Hard floors and short-pile pet rugs are the focus of this long-reach bagged model. Its floor brush is an air turbo, so do not mistake it for an electric carpet head or a small sofa brush.

Miele, 12704570
This bagged canister is controlled by foot and aimed at hard floors and short-pile pet rugs. The Cat & Dog package adds a floor turbo brush, and for sofas you use the plain upholstery attachment.
Spec by spec
| Spec | Miele Guard M1 Cat & Dog | Miele Guard L1 Cat & Dog | In practice |
|---|---|---|---|
| Rug brush | Air-driven STB 305-3 | Air-driven STB 305-3 | Switching to this body doesn't bring an electric carpet-head upgrade. |
| Bag volume | 4.5 L CO | 3.5 L TU | M1's stated volume is 1 L greater, about 29 percent more relative to L1. |
| Suction control | Mode button cycles four levels | Plus and minus foot buttons | Work out which way of adjusting suits your cleaning route better. |
| Small tools | Separate upholstery and crevice nozzles | Two-in-one upholstery/crevice nozzle | L1 merges two functions. It does not add a rotating sofa brush. |
| Charcoal filtration | Active AirClean | Active AirClean | Both use the same filter name, and that doesn't establish a measured winner on odor removal. |
| Reach | 24 ft cord, 36 ft radius | 24 ft cord, 36 ft radius | Going to L1 doesn't lengthen the published cleaning route. |
Trade-offs
Change of plan
Go with Miele Guard M1 Cat & Dog. An extra liter of stated bag space comes with M1, and the floorhead and reach stay the same.
Go with Miele Guard L1 Cat & Dog. The foot controls on L1 suit that workflow, and they don't imply stronger carpet pickup.
Decision guide
M1 Cat & Dog is the place to start for its larger bag. L1 Cat & Dog earns the choice when the foot-control layout and combined small tool are worth giving up bag volume.
Imagine a route that goes from rug to curtains to cushions. The M1 steps through its suction levels with a Mode button, while the L1 has plus and minus foot buttons. What matters is how often you change settings and whether you would rather step directly up or down. Neither control layout turns the shared turbo head into an electric brush.
Bags are used in both packages, yet the consumables differ: CO bags for the M1 and TU bags for the L1. A stock of bags for one machine is no saving on the other. Compare the correct replacements and the storage routine along with the 4.5 L versus 3.5 L volumes, and do not assume a fixed number of weeks between changes.
