Handheld or Full-size

Handheld or full-size: which will be best?

Well, a handheld engine steam cleaner is designed to get to reach those areas that are difficult like underneath pedals. Also, this type of car vapor cleaner is lightweight and easy to use.

The downside is- the handheld steam cleaner doesn’t come with a lot of powers. However, you can overcome this issue by charging it before each use.

On the other hand, a full-size car vapor cleaner is designed for deep and heavy-duty cleaning workflow. As the unit of this steam cleaner is large, they are inconvenient to use.

If you look for a steam cleaner that lets you rinse every corner of your car engine, then a handheld cleaner will be best for you.


Portability is another feature you should take into account. A portable car engine steam cleaner lets you lug it around and wash the interior of the car conveniently. Picking the handheld one will be your best choice if you are seeking a transportable steam cleaner.


Considering the warranty, it also matters when it comes to choosing a steam cleaner. In the matter of warranty, you can choose either McCulloch MC1275 or Dupray Neat Steam Cleaner as both of them come with two years of warranty.

Choosing between Handheld and Full-Size Steam Cleaners

Handheld vs. Full-size steam cleaner: Which one should I choose?

Generally, it depends on what level of cleaning you expect from a vapor cleaner.

Handheld Steam Cleaners

For quick but efficient cleaning, picking a handheld steam cleaner is always recommendable.  This type of vapor cleaner is designed in a way that lets you reach every inch of your car that might be challenging for a full-size one. Besides, the lightweight design of a handheld steam cleaner let you move it around and wash the engine thoroughly.

The only drawback of this vapor cleaner is that it does not have enough power. Here is why, we recommend you to charge the item before every time you use it.

Full Size Steam Cleaners

On the other hand, a full-size steam cleaner offers deep interior car cleaning.  As it comes with a large tank capacity, it gives you more power to fight against the toughest stains.

The con of this steam cleaner is it is challenging to move it around and use the way you want.

So, selecting the handheld best steam cleaner for cars engines might be a smart choice for personal use.
