Quick Verdict: Versatile Cleaning with Room for Improvement
The Miele Boost CX1 11735570 delivers agile cleaning and powerful suction in a lightweight, compact package, making it suitable for apartments and smaller homes. At a mid-to-upper price tier, this bagless canister vacuum earns a solid 4.0-star rating from users. While praised for its functional design and performance on multiple floors, it receives mixed marks for maneuverability and build quality. For households seeking a reliable vacuum with premium filtration and easy storage, it’s a competitive choice, yet it may fall short for those expecting ultra-premium robustness.
Unpacking the Miele Boost CX1: Design and Core Features
With its modern grey and blue matte finish, the Miele Boost CX1 aims to combine style with substance. The canister form packs in bagless convenience and an automatic cord rewind, avoiding ongoing filter or bag costs. Standing at 15.75″ long, 11.02″ wide, and 11.02″ high, its compact silhouette enables easy storage even in cramped utility closets.
This corded powerhouse weighs 17.2 pounds, striking a balance between portability and the robustness you expect from a stationary canister design. It sports a sturdy telescopic wand, a 180-cm hose, and four wheels (with side-mounted TrackDrive) for stable movement across different floor types.

First Impressions: Assembly and Build Quality
Assembling the Boost CX1 is straightforward thanks to simple push-button and touch controls. Users appreciate the quick setup and auto cord rewind. However, build quality sparks debate: while some users praise its sturdy feel, others cite “cheap low-quality” plastic and a sensation of “clumsiness” when pulling the canister behind, especially compared to older Miele models.
Engineered for Power: Vortex Technology in Action
At the heart of the CX1 is Miele’s Vortex Technology, which creates a fast airflow for both coarse debris and fine dust collection. The motor offers three adjustable suction settings, allowing users to switch power based on surface type—from delicate drapes to plush carpets.
Filtration for Sensitive Households
Equipped with a Hygiene AirClean filter, the Boost CX1 is ideal for allergy-prone families. The bagless system, combined with the multistage cartridge filter, effectively traps dust and allergens, preventing them from returning to your living space. This filtration system has been lauded by those with pets and allergy sensitivities.
Agility and Maneuverability: Navigating Corners with TrackDrive
The side-mounted wheels and TrackDrive feature offer enhanced stability on turns. Many customers like the CX1’s compactness and ability to glide across low pile rugs and hard floors. The universal floorhead transitions easily between flooring types and, paired with its lightweight build, enables fast, upright cleaning in tight spaces.
However, there are mixed reviews regarding maneuverability. While some appreciate the four-wheel balance, others say it feels clumsy or sticks when pulled at sharp angles, especially around furniture or in crowded rooms.
Universal Floorhead and Accessory Tools
The included universal floorhead handles most surfaces seamlessly: carpet, wood, and tiles. The upholstery nozzle, crevice nozzle, and dusting brush further add flexibility, letting the Boost CX1 clean sofas, curtains, and baseboards with ease. Storage for these attachments is integrated, so they’re always within reach during cleaning sessions.

Comparing the Competition: Side-by-Side with Leading Canisters

|---|---|---|---|---|---|---|
| Miele Boost CX1 (11735570) | 17.2 lbs | Yes | Hygiene AirClean | 3 | Automatic Cord Rewind, TrackDrive | 4.0 |

Who Will Love—and Who Might Not—This Model?

- Skip If: You demand ultra-premium build quality, require whisper-quiet operation, or need best-in-class maneuverability for large multi-level homes.
Premium Filtration: A Closer Look at Hygiene AirClean
The standout filter ensures cleaner exhaust air and reduces allergens. The multistage design is less maintenance-intensive compared to disposable bag systems and remains effective even with regular use. For those sensitive to dust or pet dander, this delivers tangible everyday benefits.
Noise, Ergonomics, and Maintenance
Operating at 78 dB, the Boost CX1 is average in noise output for a canister vacuum. It’s not whisper-quiet, but it isn’t overly disruptive either. Ergonomically, the comfort telescopic wand adjusts easily to varied user heights, and the dust bin release is simple for one-handed emptying.
The bin capacity fits the compact size—frequent heavy-duty users may find themselves emptying more often, but everyday apartment users will appreciate the quick-release design for hygiene and minimal mess.
Value Perspective: Price, Worth, and When to Buy
The Miele Boost CX1 falls in the mid-upper tier for canister vacuums. While MSRP fluctuates (est. per Keepa), it frequently goes on sale below retail levels. It competes directly with Dyson and Kenmore models at similar price points, but discounts can make it a strong value. Given its mixed build impressions, consider purchasing when the price dips below the typical average—best value is often found on Black Friday or Amazon Prime Day.
