Compare 8 offersOur verdict
With HEPA filtration reserved for the pricier Cat & Dog, Allergy and Parquet siblings, the base Boost CX1 is really only worth considering if filtration isn't a priority for you. A 1-litre bin and no published suction wattage - just the 890W input figure - make it hard to judge how well it will actually perform, and with no confirmed UK price it's hard to say whether it's even good value. Shoppers wanting proper allergen filtration should look at one of the other Boost CX1 variants instead.

Suction power and cleaning performance
Miele publishes an 890W power input figure for the Boost CX1 PowerLine, but this describes the electricity the motor draws, not how much suction it produces. Suction wattage, sealed suction (kPa) and airflow volume aren't published for this model, so there's no verified way to compare its cleaning power against machines that do list those figures. The vacuum uses Miele's Vortex mono-cyclone technology and a four-stage electronic suction control dial, which lets you adjust power for different floor types, but neither of these confirms actual pick-up performance. if suction figures matter to your decision, check with a retailer before buying.
Filtration: why there's no HEPA filter
This base Boost CX1 PowerLine uses a Hygiene AirClean exhaust filter rather than a HEPA filter. Miele reserves HEPA filtration for the Cat & Dog, Allergy and Parquet variants of the same model line, which also come with different floorheads. The washable fine-dust filter and filter mat can be rinsed under cold water; the Hygiene AirClean exhaust filter itself is replaceable, not washable. Anyone with allergies or asthma who specifically wants HEPA-level filtration should look at those other variants rather than this one.
Capacity, weight and handling
The 1-litre bagless bin sits in the "medium capacity" band and empties with a one-click release. At 7.8kg, it's in the heavier bracket for cylinder vacuums, which is worth noting if you'll be carrying it up and down stairs regularly, though Miele's TrackDrive side-mounted wheels and a stated stable positioning on stairs are designed to help with manoeuvring. It comes with a universal floorhead, upholstery nozzle, crevice nozzle and dusting brush, plus a park system for storing the tube and floorhead when not in use.

Who this model suits
The Boost CX1 PowerLine suits shoppers who want a straightforward, corded bagless Miele cylinder vacuum for general carpet and hard-floor cleaning, and who don't need HEPA filtration. If allergy-grade filtration, a lighter machine, or cordless operation matter to you, it's worth comparing other Miele vacuum cleaners or other cylinder (canister) vacuums before deciding.
Does the Miele Boost CX1 PowerLine have a HEPA filter?
No. The base model uses a Hygiene AirClean exhaust filter. HEPA filtration is fitted to the Cat & Dog, Allergy and Parquet variants of the Boost CX1 line, not this base model. That's worth knowing since this PowerLine version is priced at £214.14, lower than the HEPA-filtered Parquet PowerLine variant's £229.00 starting price, reflecting the simpler filtration setup. Both the washable fine-dust filter and filter mat can still be rinsed under cold water, even without a HEPA rating, while the Hygiene AirClean exhaust filter itself is replaceable rather than washable, in line with this model's 1-litre bin and 7.8kg build.
Is the Miele Boost CX1 PowerLine bagged or bagless?
It's bagless, with a 1-litre dust bin that empties with a one-click release. That bin sits in what Miele calls the 'medium capacity' band, and it works alongside the machine's 890W power input and Vortex mono-cyclone technology. At £214.14 and 7.8kg, this bagless design keeps running costs down compared with bagged alternatives, though the 1-litre capacity means more frequent emptying than larger-bin cylinder vacuums, particularly in bigger homes. The Hygiene AirClean exhaust filter, rather than a HEPA filter, completes the filtration setup on this base PowerLine model.
How much does the Miele Boost CX1 PowerLine weigh?
7.8kg, which falls in the heavier weight band for cylinder vacuums. That's worth noting if you'll be carrying it up and down stairs regularly, though Miele's TrackDrive side-mounted wheels are designed to help with manoeuvring rather than lifting. This weight houses an 890W motor, a 1-litre bagless dust bin and the Hygiene AirClean exhaust filter, all for a price of £214.14 via Miele Italy. It matches the 7.8kg weight of the HEPA-filtered Parquet PowerLine variant, suggesting the filtration difference between models doesn't add meaningful extra weight to the unit.
Is the Miele Boost CX1 PowerLine cordless?
No, it's a corded mains vacuum with a 6.5m cable, giving roughly a 10-metre operating radius. That reach suits most rooms without needing to change sockets, and being corded keeps the £214.14 price down compared with cordless cylinder alternatives. At 7.8kg, the trade-off for unlimited mains power is a heavier unit than most cordless sticks, though the 1-litre bagless bin and Hygiene AirClean exhaust filter are both designed for straightforward, no-bag-buying maintenance during regular use across carpet and hard floors.
How much does the Miele Boost CX1 PowerLine cost?
This model is priced at £214.14 via a Miele Italy listing. As with any price on this site, confirm the current figure with the retailer before buying. That's lower than the HEPA-filtered Parquet PowerLine variant, priced from £229.00, reflecting this base model's simpler Hygiene AirClean exhaust filter rather than HEPA filtration. For £214.14, you still get the same 890W motor, 7.8kg build, 1-litre bagless bin and 2-year manufacturer warranty as the pricier variants, making this the most affordable entry point into Miele's Boost CX1 cylinder vacuum range.
What warranty does the Miele Boost CX1 PowerLine come with?
A 2-year manufacturer warranty, per Miele's stated policy for its domestic appliances. That matches the warranty length across the rest of Miele's Boost and Blizzard CX1 cylinder vacuum ranges, regardless of whether a model includes HEPA filtration or not. Given this PowerLine model's £214.14 price and its Hygiene AirClean exhaust filter rather than a HEPA-rated one, the 2-year cover applies to the same 890W motor and 7.8kg build shared across the wider Boost CX1 line, providing consistent reassurance whichever variant you choose within that range.
