The Best Leifheit Window Vacuum Cleaner: Our Picks

Purchase criteria: You can use these factors to compare and evaluate Leifheit window vacuums

In the following, we will show you which criteria you can use to decide between the different Leifheit window vacuums. There are currently three different models, which we compare in this section. The criteria for differentiation are:


As already mentioned, Leifheit offers a variety of different accessories. Above you could already inform yourself about the variety and when these accessories can be used. Accordingly, you should take a look at your house or flat: If you have many skylights or very high windows and want to avoid using a ladder, a handle is a good choice. If you have a lot of mullioned windows, you should think about buying an extra narrow suction nozzle. As you can see, it is advisable to choose the right accessories and possibly the right complete set depending on your needs. Especially in sets you can often save money.

Battery life

The battery life is not the same for the different Leifheit window vacuum cleaner models and should therefore be taken into account.

The battery life is extended by the sensor technology.

Here, too, you should keep in mind the number of surfaces to be cleaned. For a small flat with few windows, a model with a short battery life is sufficient. If you have a large house with many windows, invest a few euros more for a product that runs longer. The window and bathroom cleaner (model: Nemo), for example, has a particularly long battery life of 45 minutes. The classic (model: Dry & Clean) can run for 35 minutes at a time and the cheapest model (model: Aquanta) only has a 30-minute battery life.


The Aquanta model is the heaviest model with a weight of 998 g. The Nemo model weighs around 770 g and is thus already a lot lighter than the previous model. The Dry & Clean window vacuum cleaner, on the other hand, weighs only 739 g and is thus the lightest and handiest window vacuum cleaner in the Leifheit range.

Width of the suction nozzle

In general, every Leifheit window vacuum cleaner can be purchased with a suction nozzle that has a width of 28 cm. However, there are also sets that include a narrow suction nozzle (17 cm) or you can buy it as an accessory.


The volume of the units is adjusted to each other by the sensor technology used in each unit. The Leifheit window vacuum cleaners are not necessarily known for their quiet use, but are rather moderately loud.

Guide: Questions you should ask yourself before buying a Leifheit window vacuum cleaner

Before buying a Leifheit window vacuum cleaner, you should acquire some background information. We have summarised this information for you in the following paragraphs.

What distinguishes Leifheit from other manufacturers?

What types of Leifheit window vacuum cleaners are there and which is the right one for me?

  • Leifheit window vacuum cleaner without accessories
  • Leifheit Window Vacuum Cleaner with Handle and Washer
  • Leifheit Window Vacuum Cleaner with Cleaner, Bucket and Glass Cleaner

Leifheit window vacuums can be a perfect fit for you if you are aware of the pros and cons of the different offerings beforehand. Depending on the situation in your flat or house or which accessories you already own, a different product is suitable for you. We would like to give you an overview in the following paragraphs.

Leifheit window vacuum cleaner without accessories

The Leifheit window vacuum cleaner without accessories, whether the Dry & Clean model or another, is of course the basic framework for cleaning your windows. This product is perfectly adequate for cleaning conventional window fronts, without transom windows or skylights.

  • Sufficient for simple window fronts
  • Inexpensive to buy
  • Compact
  • Powerful
  • Later purchase of accessories is more expensive than sets
  • Basic equipment (bucket, glass cleaner) necessary
  • Not suitable for high windows and sash windows
  • Corners and window frames are not cleaned

Therefore, the window vacuum cleaner without accessories is suitable for you if you have plain and simple window fronts and therefore do not need any accessories. At the same time, it is of course cheaper than sets or buying additional accessories.

Leifheit Window Vacuum Cleaner Set with Handle and Washing-in Pad

This offer convinces with the practical handle with click system, which can be easily attached to the device and extends the reach by 43 cm. This makes the product suitable for you if you have skylights, high windows or other hard-to-reach surfaces in your home.

  • Even high windows can be reached
  • window frames and corners can also be cleaned
  • sets are cheaper than buying accessories later
  • Controversial need for a washer
  • More expensive
  • Not suitable for muntin windows

The washer is intended for cleaning window frames and corners, thus enabling a particularly clean overall appearance of the windows. However, during our research, we came across some reports from customers who describe a washer as not an essential accessory and use a cleaning cloth instead.

Leifheit window cleaner set with bucket, washer and glass cleaner

If you are still completely unequipped when it comes to cleaning windows, this offer is very interesting. It includes the Dry & Clean window vacuum cleaner, but also necessary accessories for window cleaning, such as a bucket and glass cleaner. In addition, it includes a washer that is suitable for cleaning corners and frames.

  • Super suitable as initial equipment
  • window frames and corners can also be cleaned
  • sets are cheaper than buying additional accessories later
  • Controversial need for a washer
  • More expensive
  • High windows not accessible
  • Not suitable for transom windows

Of course, as the number of accessories increases, so does the price. However, if you are not yet equipped and would buy a bucket and cleaning agent in the near future anyway, this option is very obvious.

On which surfaces can I use the Leifheit window vacuum cleaner?

The Leifheit window vacuum cleaner can only be used on smooth surfaces. Rough surfaces can damage the suction lip of the device and should therefore be avoided.
