User Feedback Snapshot: Where Opinions Align and Differ
With 451 ratings averaging 3.9 stars, the Miele Boost CX1 impresses many with build quality and compactness: about 70% praise its space-saving body and durability, with some even saying it feels designed to last 20–30 years. Regarding performance, roughly 65% note the vacuum effectively removes dust, particularly on hard floors.
However, user satisfaction splits on suction quality and carpet performance: about 40% call the suction “incredible,” while another 30% find it underwhelming, especially for deep-cleaning rugs. Cleaning the dust bin also divides reviewers—some find it fast, others say it’s a hassle for large spaces.
Value for money is a repeated sore point, with an estimated 60% of dissatisfied reviewers feeling the price is not justified for what is delivered.
Two representative customer quotes:
- “Solid build, compact and quiet. Perfect for my hardwood floors.”
- “Not worth the cost – does well on bare floors but struggles on thick carpet.”

- Vacuum quality & size: Positive (approx. 70%)
- Quietness: Positive (approx. 60%)

Performance Breakdown: Hard Floor Hero, Carpet Caveats
The Boost CX1 shines in homes dominated by hard flooring. Its universal floorhead and powerful “Vortex” suction system (up to 1.6 hp/1200W) pull fine particles and debris effectively on tile, hardwood, and vinyl, and the compact design allows access to nooks that bulkier vacuums miss.
However, carpet cleaning is a weak spot. The included floorhead struggles to agitate dense fibers, and without a dedicated motorized carpet brush, the CX1 only achieves “good enough” results on low pile or area rugs—but not deep cleans or heavy pet hair removal.
Filtration, Dust Bin, and Maintenance Insights
The multistage Hygiene AirClean filter is a highlight, trapping fine particles and reducing allergens for most households. As a true bagless canister, maintenance focuses on periodically emptying and washing the dust cup and filters.
Emptying the bin is easy for small jobs, but users with large homes or high-traffic areas may find it fills fast. Those with allergies will appreciate the improved dust retention but may want to wear a mask when emptying.
Design, Size, and Storage: Maneuverability in a Compact Package
At just over 17 pounds and with a small footprint (about 16 x 11 x 11 inches), the Boost CX1 is built to slip under furniture and into corners. Four wheels and a “TrackDrive” chassis keep the vacuum stable and upright even on turns, a genuine advantage over wobblier canisters.
The adjustable telescopic wand allows comfortable use for short or tall operators, while the matte black/red design is both attractive and less prone to visible scratches.
Tool and Accessory Overview
Miele equips the Boost CX1 with a trio of core cleaning tools: an upholstery nozzle for couches and curtains, a crevice tool for tight spaces, and a soft dusting brush for shelves and electronics. The primary floorhead flips between bare and low carpet use, but be mindful—it’s not motorized, and performance drops on medium/long pile rugs.
How the Miele Boost CX1 Stacks Up to Logical Competitors
| Model | Type | Bagless? | Weight | Suction/Power | Best for | Key Weakness |
|---|---|---|---|---|---|---|
| Miele Boost CX1 | Canister | Yes | 17.2 lbs | 1200W/1.6hp | Hard floors, compact homes | Carpet deep clean |
| Kenmore 600 Series 81614 (est.) | Canister | No (Bagged) | 22 lbs (est.) | 2-motor system (est. 12A) | Mixed floors with pets | Bulkier, bags needed |
| Bissell Zing 2156A (est.) | Canister | Yes | 10 lbs | 9A motor (less powerful) | Budget, small spaces | Lower build quality |
Compared to the Kenmore 600 Series, the Boost CX1 trades superior hard floor performance and compactness for less robust carpet cleaning and a bagless design. Against the Bissell Zing 2156A, Miele wins on filtration, durability, and maneuverability, but at a significantly higher cost—making the Zing more appealing for budget-focused, light-duty users.
Who the Miele Boost CX1 is Right (and Not Right) For
- Buy if: You want a long-lasting, compact bagless canister for hard floors or light carpets.
- Buy if: You appreciate premium build and quieter operation.
- Buy if: You have a small/medium home or lots of furniture to vacuum around.
- Skip if: You need serious carpet deep-cleaning or have many high-pile rugs.
- Skip if: You’re seeking the absolute best value for money in this price class.
- Skip if: You dislike frequent emptying or prefer bagged convenience.
Price and Value Analysis: Is It Worth the Investment?
The MSRP for the Miele Boost CX1 is firmly in the mid to upper price range for canister vacuums (exact Amazon price not quoted). Typical sale and discount periods drop the price by 10–20%. According to historic trends, a buy-under price that feels justified for this model is (est.) about 20% below the maximum list, as it remains a premium product—though not offering standout carpet performance.
With mixed feedback on overall value, buyers who expect “best in class” power or a bargain may be disappointed. However, if longevity, reliability, and hard floor prowess are priorities, the cost is more easily justified for the right user.
Frequently Asked Questions
Does the Miele Boost CX1 perform well with pet hair?
It handles pet hair efficiently on hard floors and furniture, but struggles with embedded hair on thick carpets due to the lack of a motorized brush.
How often does the cartridge filter need replacement?
Miele recommends periodic rinsing and replacing every 12–18 months, depending on usage and allergy needs.
Is this model quiet in operation?
At 78 dB, it’s quieter than many upright vacuums but is not “silent.” Most users find it pleasant and non-disruptive for daytime use.
Can you use it for whole-home cleaning?
The compact design fits smaller or medium homes best. For large, carpet-heavy spaces, you may need additional tools or a different vacuum.
Is the cord length sufficient?
The automatic rewind cord is adequate for most rooms, though specifics are not listed. Users with large spaces should plan on moving the plug at times.
Final Take: Bottom-Line Pros, Cons, and Buying Tips
For hard floor homes or apartments, the Miele Boost CX1 11735800 is a standout for build quality, filtration, and convenient design. Its bagless system and stable TrackDrive chassis earn praise, as does Miele’s reputation for lasting products.
Performance on carpeted surfaces is merely average, and the price tag feels steep for those needing a vacuum that excels on all surfaces. Value is best realized for users who prize longevity, a reputable brand, and a compact footprint above all.
Verdict: Choose the Boost CX1 if you want reliable Miele quality and excellent hard floor cleaning in a compact canister. Look elsewhere if you need all-surface deep cleaning or exceptional price-per-feature.
