Epblogs verdict

The Miele CX1 Boost PowerLine is a powerful entry-level vacuum that means business. With pricing starting at £269, it is reasonably priced and combines a small design with a powerful motor. This vacuum would struggle on steep, tight stairs, but if that’s not a concern for you, it’s a flexible, reasonably priced equipment that’s a terrific choice for compact houses.

Quick Summary

For many years, Miele has been a dependable name in household appliances, and its vacuum cleaners frequently appear in our lists of the best vacuum cleaners. The Miele CX1 Boost PowerLine, which retails for $269, is the entry-level model in the German company’s new CX Boost range of three small, bagless cylinder vacuum cleaners.

We can testify for Miele’s claim that the CX1 Boost PowerLine has a footprint the size of an open magazine when it is put away. With an effective 890W motor, a multistage filtration system, and TrackDrive technology, it can capture even the smallest dust and dirt particles while maintaining a constant level of power. It has two floor head settings and four suction levels that are easily changed using your foot or hand.

Its 6.5-metre length will be sufficient for cleaning smaller areas, but we found that we needed to unplug it at least once to vacuum our 45 square meter ground floor. As a corded vacuum, it offers you more power than some cordless models of a similar size. However, this does mean that you’re tied to a plug, which limits your manoeuvrability somewhat.

There is a lot of cord for cleaning stairs, which is fortunate because their rounded shape and big wheels make them appear like they would be prone to falling off shallower stair treads.

The Boost CX1 PowerLine’s small size makes it simple to store if space is at a premium and is helpful for maneuvering the cleaner in small places and around furniture. We really appreciate that the three included tools may be safely kept on the vacuum’s handle, making them accessible when needed.

Miele CX1 Boost PowerLine Design

You’ll be happy to know that the cord is a relatively generous 6.5 meters in length, unwinds smoothly, and retracts with the push of the foot (or hand) pedal if having a power cord isn’t a deal-breaker for you when picking a vacuum cleaner. We discovered that we had to unplug it at least once to vacuum our 495 square feet (45 square meters) of ground floor space. This wasn’t a problem for us, but it is something to keep in mind if you have a larger home and don’t want to be going to the wall socket regularly.

When utilizing the Miele Boost CX1 PowerLine to clean the carpet on our stairs, the cord wasn’t a problem, but the entire design was. With extra-large wheels on its sides and additional compact swivel castors, the cleaner uses Miele’s TrackDrive technology, which allows it to turn 360 degrees on its axis to stay on course. We discovered that while the vacuum will almost sit firmly on a step in our older home’s narrow staircase with short treads, the smallest push on the hose would send it toppling off.

A multistage filtering system is housed in a model from the Miele CX1 series that has a footprint that is smaller than an open magazine. Even the smallest dust particles will be retained, which could help allergy sufferers like myself. It also works in conjunction with Miele’s Vortex technology to trap both coarse and fine dust particles.

Miele CX1 Boost PowerLine Performance

  • Universal floor head
  • Three accessories 
  • Four suction levels

The Miele Boost CX1 PowerLine did a good job of collecting fluff, crumbs and debris from both hard floors and carpets, even in tricky, hard-to-reach places.

On carpet, it removed all loose fluff with a single sweep in both directions. In addition, it efficiently sucked up dust, which, though difficult to see, was evident when the bin progressively filled up. The universal floor head quickly gathered up dust, cereal, and other debris while working equally effectively on a hard floor.

There are four suction settings available: carpet, rugs, hard floors, and upholstery. Each setting felt adequately forceful for the intended surface; for example, when we tested the carpet suction level on a rug, the suction was so powerful that it lifted the rug off the floor. These may be altered by turning the dial on the main vacuum cleaner body.

Generally speaking, the Boost CX1 PowerLine is easy to manoeuvre around tight spots in the home, such as through doorways and around corners. At 12.8lbs / 5.8kg it’s lightweight, and its compact size makes it easy to move around, although the cord length made it tricky to reach every corner of larger rooms.

It’s not too much of a challenge to carry it between rooms and up and downstairs, but we did keep mistaking the catch on the bin for the actual handle which meant that instead of lifting the vacuum cleaner, we lifted the bin up instead.

The dusting brush and crevice tools enable you to clean harder-to-reach areas like around a fireplace, and behind radiators. We also used the upholstery nozzle on some rogue crumbs residing on the sofa, but we found it easier to these off and onto the floor and pick them up with the floor head – this attachment isn’t best suited to our household, but perhaps it will be with pet owners. We found it easy to switch between accessories, as they’re all accessible when stowed on the handle. We found the vacuum to be quiet in operation compared to some other corded models.

Technical difficulties prevented us from measuring the noise level, although it seemed quieter to our ears. According to Miele, the noise output is rated at 78 dB, which is in line with the noise levels of most vacuum cleaners. Above 80 dB, the noise level starts to resemble that of a food blender. The only sound you will hear is from the motor because the floor head is not powered.

Cleaning, Maintenance and Storage

  • Cleaning, maintenance and storage score: 4.5/5
  •  Bin is easy to empty 
  •  Mini brush is supplied for cleaning the filters 
  •  Vario-clip keeps all three accessories secure onboard 

You’ll want to and need to empty the dust canister of the Miele Boost CX1 PowerLine frequently. A catch on the dust canister is sometimes mistaken for the carry handle.

On the front of the bin is the dust container release catch, and there are other release catches that allow access to the filter frame, pre-filter, and fine dust filter with filter mat. All of these components can be cleaned with a shake, a brush with the provided mini brush, and a rinse under cold running water.

As for longer-term maintenance, Miele recommends that you replace the Hygiene AirClean and HEPA AirClean filters once a year, and replace the fine dust filter every three years.

The Miele Boost CX1 PowerLine doesn’t take up much room when stored, which makes it perfect if space in your home is at a premium. The comfort telescopic tube slides onto the ‘park system’ which although does make the stationed vacuum cleaner tall, it doesn’t make it any wider. 

On the handle is one of the vacuum cleaner’s most useful features – the on-board storage clip for the tools, which Miele calls the Vario-Clip. This ensures that the crevice, dust and upholstery tools are always there when you need them, although if you’re cleaning underneath the bed or couch with the tube low down they may scrape along the floor a little as you clean.
