Miele S4212 Vacuum Cleaner Review


Avg. consumer rating = 98/100 

There are two Miele S4212 vacuums - the S4212 Polaris and the S4212 Neptune.  The base model, the Miele S4212 Polaris is the replacement for the Miele S4210 Carina.   It should be noted that the S4212 Polaris is entirely the same vacuum with the same features as the S4210 Carina.  The only difference is the color - the Polaris is a light blue color (baby blue) while the Carina is a light yellow.  Like the S4210 Carina, the S4212 Polaris is the entry level Galaxy S4 series Miele canister vacuum, and like the Carina it is recommended for short-pile carpeting, area rugs and smooth flooring.

The S4210 series is still available in many stores and sells very well.  As a result there are quite a few more customer reviews and ratings for this series.  However a few were dug up for the Miele S4212 Polaris and as you can see it also gets great reviews (given that it is the same vacuum this is not unexpected).

There is also a Miele S4212 Neptune – this is the replacement for the Miele S4210 Antares.  Again, the same vacuum with a different color – the Neptune is turquoise.  Like the Antares the new Miele S4212 Neptune comes with the Miele STB 205-3 Turbobrush and the Miele SBB300-3 Parquet Floor Brush.  The Neptune is recommended for low to medium-pile carpeting, area rugs and smooth flooring.

Miele S4 Series Vacuum Testing
As an aside it is interesting to learn that all Miele S4 series vacuums, including the S4210 and S4212 series, undergo a number of tests to ensure the durability of each unit.  These tests include the following (and this information is all according to Miele): 

The Cable-Pull Test
The vacuum power cable is pulled out and retracted over 10,000 times.  This is done to ensure the cable reel will perform effectively for years.
The Hose Test
Hose endurance is tested by hanging, from the hose, a vacuum cleaner plus an additional 11 lbs of weight then stretching the hose thousands of times.  The hose must pass this undamaged.

The Floor Test
Miele floor tools and accessory cleaning brushes are tested on many miles of different flooring, and are also repeatedly dropped from a height of about 3 feet.  The tools and accessories must pass these tests undamaged to be approved for production.

The Threshold Test
The S4 series vacuum's castors, bumper strip and outside casing are tested on miles of track where stresses such as simulated door thresholds, bumps and harsh curves are exerted.

The Longevity Test
The vacuum cleaners are tested to last a minimum of 1,000 operating hours or what Miele indicate is an average of 20 years residential use.

I just found a S4212 at Costco liquidation centre for $375. tax in. I called Miele and they will not honour the warranty because of where I am buying it. In your opinion is the warranty a big deal? Should I worry? Also noticed you mention that the brush roll is suction driven ..not sure what this comes with but it it a carpet brush 205-3. Not sure if its suction or powered. Any help would be appreciated!! Thanks!

Hi Dianne

We can\'t be certain as the S4\'s were retired by Miele some time ago. Perhaps they are still making them for some retailers however. We have seen this one on Costco ourselves and our best guess would be something close to the S4212 Neptune. These are fairly good machines in our opinion. Note however that the brushroll is suction driven and not motor driven. This can make a difference depending on the amount and type of carpet you intend to clean.

There are many reasons why we feel the Miele is the ultimate vacuum cleaner. The first is that is is a sealed system and there are only two systems which are airtight so that all exhaust goes through the HEPA filter, without any leaking. The bag is part of the sealed system and while it may cost a bit more, it is a well-thought out system with an airtight valve on the bag and the bag can last for a couple of months with every day cleaning. All of this adds up to what we consider to be the best answer against dust-mites.
