After the boom in cordless vacuums over the past couple of years, some recent launches have taken us back into the world of corded vacuums.
Why? After using a cordless cleaner, a corded vacuum seems extremely powerful. And it’s nice not to worry about having to recharge it. But it’s also because brands are spending time developing wired products to make them more compact and feature-rich.
The Miele Boost CX1 is a corded vacuum designed for small homes where space is limited but real power is still needed.
Design and build
- Bagless – washable filter
- 360° maneuverability
- Four power settings
The Boost CX1 is a compact yet powerful canister vacuum. That’s really his USP: according to Miele, his print can fit in an open magazine (spoilers: it can). But while that makes the canister itself easy to move and store, you still have to deal with the unsightly wand and hose, which are always much harder to find.
The convenient parking mode, which allows the wand to slot into the side of the cartridge and remain unsupported, provides a neat storage option.
It is also very manoeuvrable in use, with a front wheel that has 360° adjustment, a small rear wheel and the two large wheels built into the sides of the cleaner. The wand itself is adjustable in length, so you can find a comfortable height for you.
It is a bagless vacuum cleaner, with a large transparent dustbin. It pops out easily via the top handle, and when you’ve just emptied it, the entire base of the bin pops open, so it’s easy to remove hair, dust and lint without digging around. The dust filter can also be washed in the sink.
There is a second filter system on the air outlet at the front of the vacuum cleaner. It comes in the form of a removable honeycomb grid. Below is a filter cartridge, which is also removable. It’s an efficient system, with the exhaust air smelling clean, not dusty.
The controls of the Boost CX1 are simple. There is an on/off button and a cord retraction button, both of which are large enough to be operated with a simple press of the foot.
Between them is a power dial with four settings.
It comes with a simple set of attachments: a round brush head (great for removing pet hair), a crevice tool, and a small wide-mouth tool. I’ve never been impressed with Miele vacuum attachments and this set is about as basic as it gets.
However, once again, there is a well thought-out storage: the assembly clips onto the joint between the hose and the suction wand.
I found it too annoying to clean while attached, but it was handy for parking the vacuum.
- Better on hard floors than carpet
- 6.5m retractable cable
- Cartridge weighs 13.4 lbs (6.07 kg)
The power dial has four recommended settings: lowest for curtains; the second for carpets and cut pile carpets; the next for carpets and loop pile carpets; and the highest setting for hard floors. There is a corresponding foot pedal on the vacuum head to switch between carpets and hard floors.
Despite this, I felt the second setting was more than adequate on all kinds of surfaces. At this level, it is also very quiet.
The vacuum is easy to move, but the wheel design means it won’t swerve or roll. It is also virtually impossible to knock it over.
The fact that the cable is long (6.5m) and retracts at the press of a button also helps alleviate the annoyance of having a cord.
However, vacuuming the stairs is not the easiest thing with the Boost CX1. The cartridge is square in shape and may be too wide to sit firmly on a step (it measures approximately 40 x 27 x 25 cm). But even if it is, you’ll still need to move it with you as you climb.
The cartridge body weighs 13.4 lbs (6.07 kg), which is a lot to carry around while vacuuming. The cordless Dyson V15 Detect, by comparison, weighs around 6.7 lbs (3.3 kg).
At least, thanks to its telescoping wand, you won’t need to lift the canister while you clean overhead, even if you’re vacuuming cobwebs from a high ceiling.
There is another problem thanks to the lack of a roller in the cleaning head. This makes vacuuming carpets quite difficult as even on the lowest settings the vacuum tends to stick. Between that and the friction, you have to exert a lot of force to push it onto the mat.
While this vacuum should work just as well on carpets as it does on hard floors, the truth is that it’s much better suited for the latter.
Price and availability
There are three models available, and color options include white, gray and black: the Boost CX1 (which we test here, £269 from Amazon UK; $449 from Amazon in the USA); the Boost CX1 Hard Floor, which is optimized for use on floors such as parquet (£329 from Amazon UK; $549 direct from Miele in the US); and the pet-friendly Boost CX1 Cat and Dog (£369 from John Lewis UK; $649 from Amazon in the US).
All are cheaper in the UK than in the US.
I’ve always found Miele appliances to be high quality, but I don’t recommend them as often as I would like due to the high price tag that comes with them, which puts them firmly in the luxury category. However, the Boost CX1’s reasonable price means it should have wider appeal.
It is beautifully designed and built to last. However, there are a few caveats. It’s not a vacuum that will make your life easier if you have acres of carpet or lots of stairs. But if you have mostly hard floors and are looking for a powerful, compact vacuum, the Boost CX1 is a solid choice.
