Miele S4212 Neptune Canister Vacuum Cleaner Review

The Miele S4212 Neptune Canister Vacuum Cleaner is a very light-weight canister vacuum with incredible power. It uses a 1200 Watt motor that makes it able to pick up just about anything. However, the suction is adjustable so you can use it on even the most delicate rugs.




Considering how light-weight and compact the vacuum is, plus all of the useful attachments, we must say that this is one best canister vacuums available and it gets our highest rating for cleaning power, durability, and long term value.

First of all, the Miele S4212 canister vacuum cleaner has a very strong suction. In fact, the 1200 Watt vortex motor delivers 150 CFM air flow (which is a good deal for a canister vac) which will tackle any job, even in high carpet. But, don’t let that fool you into thinking that it is noisy.

In fact, users often comment about how the Neptune remains quiet even though its power is easily observable when its being used. So, you don’t have to worry about waking up the sleeping baby if they’re in a crib a few rooms away.

Now, lets talk about weight. The last thing that you want to do is lug around a heavy vacuum cleaner, especially if you’re going up or down stairs. The Miele S4212 Neptune Vacuum weighs in at only 10 pounds. Its incredibly compact because it is a canister vacuum. This makes it very easy to carry all around your house to get into all of those corners and even up high.

When you do need to clean up high, you can just extend the vacuum wand. Plus, you wont have to unplug the machine as you move from room to room since you are able to travel 30 feet from the outlet with its long retractable power cord.




Attachments are important for any vacuum, and the Miele Neptune S4212 does not disappoint. Not only do you get a parquet attachment to use on your hardwood floors, but you also get a crevice attachment, dusting attachment, and even a Turbobrush to use on rugs.

The adjustable suction will allow you to use the cleaner on any rug in your home. You dont have to worry about damaging older or more expensive rugs like you would if you were using almost any other kind of vacuum.
