Is Auto Dosing Worth Paying For?

Automatic dosing of detergent and conditioner, is it a good thing or a bad thing?

In the world of commercial machines automatic dosing or auto dosing has been about for a while and in full blown commercial use we can understand why.

Bosch i dos auto dosingThe primary reason is to control costs, preventing operators from using too much detergent or indeed too little as often the machines will be operated by unskilled labour so, it makes sense there. Plus you’ve got all the space you need, adding extra size to the machines is not of concern normally and the cost of installing such system not prohibitive in relative terms.

In a domestic setting, not so much.

You’ll see these systems labelled up as i-Dos, self-dosing, TwinDos, auto-dose and so on but in essence, they’re all the same thing, just differing flavours.

Now we totally get that it sounds great, lad up the machine with “stuff”, wash things and that’s it. The marketing bumph makes it sound great, it’ll improve your life, give you more time, make you not worry and all the usual garbage we see but, is it actually true?

In large part, no it isn’t. It’s a glorified advert, of course it’s not exactly fully accurate will we say, to be kind.

Here’s why that’s the case explained for you and why we would recommend you avoid these systems like the plague.

  Only Liquids!

Out the gate all the domestic systems we’ve seen from the like of Miele, Indesit, Bosch and so on have the same underlying fundamental problem, they can only use liquid detergents.

Many people might not think this a problem but, it is and a big one.

You see no liquid detergent can contain bleach for technical reasons, it’s just not possible to do so when you use liquids all the time you get issues with smells as bacteria grows in the machine leading to the old smelly washer problems.

Where people combine that with constant low temperature washes we see this problem made worse and potentially damage to the machine so all in all, it’s not even remotely a good thing in our estimation.

For far more information non this please see our article all about detergents for more on this topic as well as others we will talk about here, that will cast more light on why we hold this position on auto dosing.

  Not In Control

So here’s the other big thing about auto-dosing, you’re not in control of the dose, the machine is and the simplistic logic within it.

Mistake number one many people get into trouble with is endowing washing machines (and other appliances) with having more intelligence than they actually have. They’re pretty dumb really for the most part.

The chance of a machine figuring out that you’ve banged in mixed items is zero. Mixed colours, not a hope. mixed up wash labels, no chance.

The machine will wash on the program you select irrespective of what you put in it and, when there’s an auto-dose system in operation, it will does according to the program that you select. What that means is, if you select the wrong program, it’ll wash wrong and now it will also dose wrong as well.

That leads to use being a very fickle affair, you need to sort laundry completely correctly, select the correct program and the correct soiling level or, it won’t wash well.

None of the machine currently available can get around that problem and without some hateful fuzzy logic or AI and RFID or something in the clothes, we can’t see any way around that problem. Unless you can get a robot that will do it all for you of course but, we’re probably some way off from that being a reality.

So if you are perhaps under the illusion that somehow the machine will magically work all that out for you, please rethink as it simply will not do so. You could actually end up with more to do, not less.

  Bigger Cost, Then More Cost

Any machine with an auto dosing system is going to cost more, probably significantly more.

It will have extra bits in it that at some point will probably break and they won’t be cheap. To us it’s just more points of failure never mind the potential problems outlined already.

Miele twindos  auto dosing reviewYou also have systems like Miele’s TwinDos auto-dosing system that uses specific detergents that are delivered in a sort of cartridge type way and, they ain’t cheap.

We guess you could argue that, if you can afford a Miele TwinDos machine than you probably aren’t all that bothered about the cost but we’re sure you don’t want to get ripped off nor do you want to get poor results or have more hassle. The bottom line here is, this is going to cost you more and possibly a lot more over the time you own the machine.

Of course if the manufacturer can lock you in to buying stuff from them and them exclusively at whatever they want to charge you, sure they’re gonna do that. We would advise strongly to avoid anything that traps you in this way as there’s no need for it and, it probably won’t be doing you any favours.

  Avoid It

On balance we cannot see any real world benefit in having an auto dosing system in a domestic washing machine, to us it just makes no sense at all. There really are no redeeming factors from a technical perspective in design or in use.

We get that on the face of it that many people might think this a great idea and it does play to the “lazy” in us all, why do something you can have a machine do for you but here, it’s not really doing that much and may well end up making things more difficult for many people, not easier at all.

Therefore our advice, avoid auto-dosing system, they’re not worth the hassle or the expense.
