Miele Classic C1 Delphi Canister Vacuum Cleaner Review

Last updated on August 29th, 2022

Miele Classic C1 Delphi Canister Vacuum Special note: The Classic C1 Delphi is currently unavailable, the newer model – Miele Compact C2 Electro+ Canister Vacuum. 

Not so long ago Miele, a famous German manufacturer of home appliances and professional equipment had launched its Classic C1 series of canister vacuums at an affordable price. The C1 series presents four canister cleaners and Classic C1 Delphi model is one of them.

For your information, the previous model of Classic C1 Delphi is Miele S2 series, the S2121 Delphi. Compare to the older model, this model is more compact while still maintaining the great features available in the old model.

Why I know this? Because I personally buy and use it at home and that’s why I can tell the whole truth about this canister vac. I am going to write an unbias review for this Miele Classic C1 Delphi cleaner so you will know all the advantages of having this vacuum.

But just in case, you can check out this vacuum at the amazon.com or you can continue reading the comprehensive review below.


Discovery of the Great Features of Miele Classic C1 Delphi Canister Vacuum

There are lots of great features but I particularly highlight the following features. If you want the comparison table between the Classic C1 series of vacuums, click here.

  1. Uses AirClean filter (optional for HEPA filter) with auto-seal dust bag.

The Classic C1 Delphi is best to those who have a mixture of bare floors and low to medium carpeting like we do. We do not have anyone suffering from asthma or allergies so the supplied AirClean filter is enough for us.

But it is good to know that if we ever need to or I start feeling that it is not managing I can always purchase additionally the HEPA filter. Miele’s filtration system catches over 94% of dust and allergens and the auto-seal closure Filterbag are made of several protective layers.

Every package of bags comes with the new pre-motor and air-clean filters so it is very simple for me to know when they are to be changed – with every new box. And for the bag replacement time there is an indicator reminder. These features I like very much because spending my days with two children at home I sometimes feel myself lost in time.


  1. Great suction power, suction control via rotary dial with 6 variable power settings.

The suction abilities of Miele Classic C1 Delphi canister vacuum cleaner are similar to those, which I would expect from an upright. Having 6 speed levels (control via adjustable rotary dial) from lowest of 300 watt to highest of 1200, it adapts the suction power to the type of cleaning and allows avoiding unnecessary eating of light rugs or drapes as well as precious Lego parts hidden by kids in the upholstery.

The Delphi’s performance on the carpet is superior thanks to the powerful engine with high-output Miele-made vortex motor system and an included electrical floor brush that has its own independent motor. The vac sucks out the dirt and dust from the carpets very well while the brush picks up all the hair. After vacuuming carpets look very fresh and I feel safe for kids playing on it. Of course, cleaning of bare floors is close to nothing for this cleaner.


  1. Low noise level.

One of vacuums’ best sides for me and for many other people who wrote their reviews for Miele Classic C1 Delphi is the low noise level, actually, its quietness. Since being a child I hated to vacuum exactly because of the noise provided by my parents’ old vacuum monster. When I became older and started choosing vacuum cleaners myself it has always been an issue for me. Finally now I do not have to strain my ears all the time during vacuuming in order not to miss a phone call or a doorbell. Besides, kids are also not afraid of the cleaner anymore.


  1. Lightweight with various onboard tools.

Delphi rolls very quickly on its wheels and it takes a very short time now to clean the house. Its’ stainless steel electric telescopic wand and hose provides easy access to those areas that used to be hard to reach. And even if it is still not enough or the angle is not very convenient (like for cleaning the tops of wardrobes) I simply climb on a chair and hold the canister in one hand. Thanks to the low weight and good carrying handle it is not a problem at all.

The accessories coming with Delphi model are crevice tool, upholstery nozzle and a dusting brush. But the best, of course, is the SEB 217-3 Electro Comfort Electrobrush. These tools give the convenience to clean all types of floors especially low to medium-pile carpet.


  1. Long warranty periods

Backing the quality of its product has never been a problem for Miele, and its warranty on all vacuums is the latest example: Miele offers a best-in-industry 7-year warranty on its Vortex motor, a new 7 year casing warranty which covers the upper and lower housings, and one year on all parts and labor.

To summarize, here are the top features of this canister vacuum:

  • Lightweight and compact canister vacuum.
  • 1200-watt Vortex motor, 6 levels of speed control.
  • AirClean filter; optional for HEPA filter.
  • Quiet operation through better engineering.
  • 76 quart, Type G/N, AirClean dustbag, with spring-loaded, self-sealing collar.
  • Dustbag change indicator alerts you to replace the hygienic bag.
  • Filter grill
  • Safety shut-off on overheating.
  • Electric telescopic wand to extend the reach; impressive 29.5-foot operating radius.
  • Space-saving storage bracket (VarioClip) on side of vacuum.

What Existing Users Are Saying About This Delphi Vacuum Model?

Searching for information about this model one will not find too many of Miele Classic C1 Delphi reviews. But those, which are present in the Internet, are rating the cleaner exceptionally highly. No surprise as it is a high quality machine with a wide range of features and options that are rarely combined in a machine of the same price level.

Reading one of the reviews of Miele Classic C1 Delphi I learned that basically there is not much differing it from the machines of more expensive Miele S6 and S8 series. It is in majority some small details, which do not influence that much on the quality of cleaning and its result, like e.g. artificial bristles vs. natural ones in dusting rush or a plastic bumper instead of rubberized.

Paying less for almost professional cleaner from a trusted producer – that is what you get in the bottom line when purchasing Miele Clasic C1 Delphi canister vac.


Conclusion: A Quiet and Powerful Canister Vacuum!

If you are looking for a new mid-range canister vacuum cleaner, then you need to consider this cleaner. All the personal experience above is true and you can rely on this canister as a top cleaning tool for a cleaner and fresher air environment.

Its good on various types of surfaces and it cleaning power really difficult to match with other vacuum models of the same class. The long warranty periods act like reassurance to you if you get the vacuum now!
