The catch
Miele Boost CX1 Cat & Dog
A 1 L bin is small, so a heavy dry debris load means stopping to empty it sooner.
Side by side
Both include HEPA filtration and the same STB305-3 air-driven rug brush, so capacity and the hard-floor tool make the practical difference. Boost CX1 Cat & Dog is for you if the canister has to fit a tight storage space. Blizzard CX1 Turbo Team is for you if a 2 L bin is worth more than a smaller body.
Before you buy
Against Blizzard's 159,650 mm², Boost's rectangular body plan comes to 112,000 mm². By this limited measure, that makes Boost about 30 percent smaller. It works as a quick check for a cupboard but isn't a full storage-volume or maneuverability test.
Where this comes from
Multiply 400 by 280 to get 112,000, and 515 by 310 to get 159,650. (1 - 112000 / 159650) x 100 comes to about 29.8 percent. The dimensions on both are official body figures.
The catch
A 1 L bin is small, so a heavy dry debris load means stopping to empty it sooner.
The catch
Airflow drives the floor brush, which has no electric drive and no carpet-height adjustment.

Small home, pet rugs: Boost CX1 Cat & Dog or Blizzard CX1 Turbo Team? This page compares measured body dimensions, 1 L vs 2 L bins and hard-floor tools.
Two HEPA-equipped air-turbo packages, and the choice is between storage space and bin room.
Which one fits
Both kits still need storage for the hose and head, but Boost's body rectangle is smaller.
Nominal container room is 1 L greater with Blizzard.
Blizzard pairs the air turbo with its own dedicated parquet brush.
Each comes with plain small upholstery nozzles and not a hand turbo.
Each publishes an identical 32 ft operating radius.
In practice
Against Blizzard's 159,650 mm², Boost's rectangular body plan comes to 112,000 mm². By this limited measure, that makes Boost about 30 percent smaller. It works as a quick check for a cupboard but isn't a full storage-volume or maneuverability test.

With a shedding pet, bin room can matter even if the home is small. Boost leans toward storage, whereas Blizzard gives twice the stated bin volume. Work out which constraint really interrupts your clean, and don't treat a small floor area as proof that a small bin is enough.
Boost is listed at 1 L and Blizzard at 2 L. The body rectangles differ, but STB305-3 and HEPA filtration come with both.
Cord and operating radius stay the same despite Blizzard's larger body and bin. When the problem is an outlet behind furniture, neither model has a reach advantage. What Blizzard adds here is container room and the dedicated parquet tool.
A 21 ft cord and 32 ft operating radius are listed for both models. Boost supplies an AllTeQ combination head, and Blizzard adds SBB300-3.

Miele, 11735550
An air turbo floor brush and a HEPA filter come with the compact Boost body here. A small home with short-pile pet rugs is the fit, provided you can live with emptying the bin often.

Miele, 10829400
A 2 L bin, a HEPA filter and an air turbo floor brush come together here. It works for hard floors and short-pile rugs if skipping replacement bags is worth more to you than a compact body.
Spec by spec
| Spec | Miele Boost CX1 Cat & Dog | Miele Blizzard CX1 Turbo Team | In practice |
|---|---|---|---|
| Dust container | 1 L | 2 L | Blizzard's nominal bin volume is twice as big, which doesn't prove twice the time between emptying. |
| Body rectangle | 400 by 280 mm | 515 by 310 mm | Not counting hose, wand and parked heads, Boost's body rectangle is about 30 percent smaller. |
| Rug brush | STB 305-3 air turbo | STB 305-3 air turbo | These specifications give no support to a claim of stronger rug pickup, because the head family is the same. |
| Hard-floor option | AllTeQ combination head | SBB 300-3 parquet brush | Boost keeps a mixed-surface nozzle, and Blizzard comes with a dedicated swiveling hard-floor brush. |
| Filter | HEPA AirClean | HEPA lifetime filter | HEPA comes with both. The stated maintenance still applies to Blizzard's fine-dust system. |
| Reach | 21 ft cord, 32 ft radius | 21 ft cord, 32 ft radius | Extra published reach doesn't come with the larger Blizzard body. |
Trade-offs
Change of plan
Go with Miele Blizzard CX1 Turbo Team. Nominal capacity doubles with the 2 L container, and the rug-brush type stays unchanged.
Go with Miele Boost CX1 Cat & Dog. It's easier to find room for the smaller 400 by 280 mm body rectangle, as long as you also measure the hose and parked tools.
Decision guide
Boost Cat & Dog is the pick when storage space is a hard limit, and Blizzard Turbo Team is the pick when twice the stated bin volume and a dedicated parquet brush will serve you better.
Cut a paper rectangle to the body dimensions and lay it in the intended storage space, then leave room for the hose, wand and spare head. At body level the Blizzard is 115 mm longer and 30 mm wider. That gap can settle a tight cupboard fit before the larger bin even comes up.
STB 305-3 comes in both packages, so the specialist rug head is no reason on its own to move up to Blizzard. Look at the rest of the route. Blizzard adds the dedicated SBB 300-3 parquet brush, whereas Boost relies on its combination head for bare floors. Whether that is worth it depends on your surfaces and how many tool changes you will put up with.
