What Is Auto Dosing In Washing Machines?

Auto dosing has been used in commercial washing machines for a number of years. It makes sense in a commercial environment where human error could so easily cost a company a lot of money and extra work.

The idea is that the machine detects how much laundry is in the drum and automatically adds the correct amount of detergent to ensure that particular load gets washed and rinsed correctly.

The machine has a detergent reservoir that is filled with detergent and once the drum has been loaded and a programme has been selected, the machine calculates exactly how much water and detergent is needed to successfully wash that load.

How Does An Auto Dosing Washing Machine Work?

Auto dosing washing machines rely on technology to detect the weight and condition of the laundry to determine exactly how much detergent is needed to clean that load.

It will add the correct amount of detergent for each wash load. Unlike the way we currently add detergent where we might not use quite enough. Or more likely use too much detergent which is then left in the clothes after the final rinse.

As you fill up a reservoir in the washing machine, it means you will not even have to think about detergent for around 4 to 5 weeks depending on how often you use your machine.

What Are The Benefits Of An Auto Dosing Washing Machine?


The main benefits of an auto dosing machine include;

  • Less Detergent Used
    It is claimed that using an auto dose washing machine uses 30% less detergent compared to manually adding detergent.
  • Saves Money
    As less detergent is used, you save money on the cost of replacing detergent so often.
  • Accurate Detergent Dosage
    Auto dosing takes all of the guesswork out of adding detergent to a wash load. It calculates exactly the amount needed based on the materials being washed, how dirty they are and the amount of laundry in the drum.
  • No Need To Add Detergent Every Wash Cycle
    Some auto dosing machines have a detergent reservoir of around 1.3 litre capacity. This should last for around 26 washes.
  • Makes Clothes Softer
    If you use too much detergent, it doesn’t all get rinsed out which leads to clothes becoming hard. This can lead to scratchy towels, holey shirts and rough sweaters. Using an auto dose system eliminates the chance of using too much detergent.

What Are The Disadvantages Of An Auto Dosing Washing Machine?

There are several disadvantages to using an auto dosing washing machine which include;

  • The Purchase Price
    Washing machines with auto dosing technology tend to be at the pricier end of the washing machine scale. Of course auto dosing isn’t the only new innovation available on these high end appliances, but does the extra purchase price merit the functionality?
  • Limited To Liquid Detergents
    All auto dosing systems can only be used with liquid detergents. If you prefer powdered detergents, auto dosing is not really going to work for you.
  • Often Uses Too Much Detergent
    The preset amount of detergent is often more than is normally used or needed. The advertising blurb states that it uses exactly the correct amount of detergent but the reality is often different.
  • The Cost Of Detergents
    If you use the manufacturers preloaded detergents they work out around 50% more expensive than your regular liquid detergent.

Is It Worth Buying A Washing Machine With Auto Dosing Technology?

As we said earlier, the auto dosing technology has been around for some time in commercial washing machines. Where it has proved to be very useful for large, industrial cleaning companies.

Whether it’s worth buying a similar type of technological advancement for your own home, is something only you can answer.

It does reduce wash times, detergent usage, water usage and electricity usage. Which could be advantageous to you and your household. But whether the savings justify the extra purchase price is something only you know.

One thing worth remembering is that what often happens with these new technological advancements is once they’ve been around for a while, the price seems to even out. 

So if there’s nothing wrong with your current washing machine, we suggest you wait until you actually need a new one before deciding.
