By admin | Canister Vacuum Reviews

First Impression:

Canister vacuums are usually considered for bare floors. Moreover, they have always been on the weaker side when it comes to high carpets. The Miele S2121 Delphi canister vacuum review will take you through the details of this vacuum.

Outstanding performance on hardwood floors and low-pile Carpets. But, it falls short of its performance on high carpets. The S2 series of vacs from Miele have a reputation of delivering great performance at an affordable price. The S2121 Delphi is no exception. The build quality is outstanding and so is its performance. It has been designed for hardwood floors and low-pile carpets and it delivers very well on them. However, its performance begins to waver when we try to test it on high carpets.

The vacuum does not feature a motorized brush roll and it does not have HEPA filtration either. While you may feel that the price fairly high, you must understand that it is one of Miele’s low-end models. The high-end vacs sell for over $800. The fact that Miele has been manufacturing vacuums for decades. Now, you will find the fit and finish of this model to be one of the best when compared to other vacuums.

This model of Miele can move around with great ease on the three casters. It does not flip over or get caught in furniture which is often an issue with the average canister vacuum. At 13 pounds, the vacuum glides smoothly over a variety of floorings. It is almost half the weight of many other canisters of the same type.

The weight should not deter you into thinking that the vacuum is not well built. The perfect finish and strong build of the vacuum gives it a perfect design. There are no loose parts and everything is perfectly attached so that you do not hear unwanted rattling while using the vacuum.



The brush does an excellent work on bare floors but it gets kind of bogged down when it comes to high carpet. The buttons are located at the back of the cleaner and they are easy to reach without bending over, however, fingertip controls on the hose are a lot more convenient.

We found the power cord to be relatively shorter which makes it difficult for you to clean the room without stopping too frequently to change the power outlet. We love the ability of the vacuum to retract the cord so you do not have to worry about tangles. The wand can be extended up to four feet so that you can clean up spider webs from the ceiling as well. The extendable wand is great for cleaning up curtains too.Miele S2121 Olympus Canister Vacuum Review

The dust bag included in the model comes with a plastic collar. This makes it extremely easy to slide it in and out of the canister. The flapper ensures that the dust does not come out. This makes the S2121 one of the best models when it comes to removing the dust bag without creating a mess.

With so many great features, the S2121 is a great machine, but it is worth noting, that the vacuum does not come with the HEPA filtration.


The Delphi is designed particularly for hardwood and low pile carpets. The vacuum performs perfectly well on them, but high pile carpets is a problem area. The brush is not strong enough to remove fine dirt and dust from the high pile carpets. This is because the brush roll is not motorized. It is a straight suction brush.

Miele does sell optional brushes and if you would like to use one of those powered brushes, then let us tell you that you may end up with a heavier suction brush which cannot be utilized efficiently because the hose does not have a wiring harness.

The disposable bags are large enough for an average household. It can contain approximately half a gallon of dirt. Replacing the bags is easy and less of a mess than other vacuums. One of the best qualities of the Miele S2121 Delphi is that it is one of the quietest vacs that we have used.

The S2121 may sound pricey for a vacuum that works on hardwood and low-pile carpets only. But it performs outstandingly well in both the areas. The vacuum is light in weight and exceptionally quiet. It has been built with precision and it is very durable. It cleans very well and its extendable wand along with the accessories included with the vacuum make deep cleaning substantially easy.
