Window Vacuum Cleaner Buying Guide

Cleaning windows is not an easy task, especially when they collect residue from lack of maintenance (hey, we won’t judge!). The window vacuum review has introduced you to the best-reviewed products of 2021, but here are the three most important things you need to note when browsing through your options.


Window Vacuum Cleaner Buying Guide

Window vacs come in different shapes and forms. The most common type is the handheld vac that uses a 10-20 W motor to suction dust and debris from windows. The collection of dirt is spilt into a separate (or integrated) water reservoir that is cleaned afterwards. Another model is the telescopic vac that is a lifesaver for large windows. This vac is built of the main base, a suction nozzle and an adjustable rod. The cleaning process is identical to the first models’, but some telescopic vacs also support an upwards motion as opposed to the standard downwards one. This is especially helpful with removing streaks that are more prone to result with telescopic vacs than handheld ones. All in all, a handheld vac is more precise and gives better cleaning results, but a telescopic one is more practical.

Battery Life

Because window vacs are battery-operated, you need to make sure that the product you’re interested in is efficient in its use. For the best-uninterrupted cleaning process, you want to charge your vacuum cleaner fully. For most vacs, the standard charging time is 2.5 hours, which can provide with a run time of 30 minutes. More sophisticated models can support times as long as 45 minutes, but they usually employ a longer charging time as well. Considering how cleaning a set of windows both inside and outside takes about 5 minutes, a unit with a run time of 30 minutes is ideal.


Window Vacuum Cleaner Accessories

Once you give your cleaning vac a try, you will see that its accessories make the cleaning process much more comfortable and shorter. Firstly, your window vac must have two nozzles: one for large windows and one for small ones. Cleaning edges and getting through to hard-to-reach areas is a pain, so a narrow nozzle can be a real lifesaver.

The same applies to large ones because they cover a wider surface than standard nozzles, so the required cleaning time is cut in half. Spray bottles are also very convenient since they allow for cleansers to be within reach, resulting in overall better cleaning results. Last but not least, we have microfibre cloths that are incredible at collecting and removing dust and residue before the cleaning process starts.

Giving your house a thorough clean?

With lockdown rules and cut-down working hours, there isn’t much to do around the house. If you want to enhance your productivity and contribute to your well-being, you can go on a cleaning frenzy that involves all the family. Why don’t you combine your new window vac with a cordless vacuum or a handheld steam cleaner?


Q: How do you use a window vac?

A: Each cleaning vacuum poses a different model, different components and sometimes even different use. However, most products usually have a base, a suction nozzle, a spraying bottle and a microfibre cloth. Considering that Karcher is the most reliable windows vac manufacturer, their how-to guide on cleaning windows includes these steps:

  1. The spray bottle needs to be filled with water and preferred detergent. Make sure to use window-exclusive cleaning products as other ones may leave your windows stained.
  2. Spray the concentrate into the window and agitate using the microfibre cloth. The entire window surface must be reached, so you can have a streak-free clean.
  3. Start with moving your vacuum cleaner on a downward motion. Most brands design their vacs to be compatible with both vertical and horizontal motions, but some provide with an upwards motion too.
  4. If your vac has left streaks alongside the window’s surface, grab a clean, dry cloth and get rid of the spots. Voila! You have clean windows.

Q: How does it work?

A: A window vacuum works by using a motor-generated suction force to gather dust, stains, grime and condensation from flat surfaces like windows, mirrors, tiles or other glass exteriors. Most window vacs include a rubber-based nozzle that suctions the dirt from the windows’ exterior and vacuums it into an integrated water reservoir.

Q: What is the best window vac?

A: The best window vac of 2021 is the Anniversary Edition of the WW2 Kärcher window vac model. This unit is renowned for its fast-charge, long run time, efficient use and excellent cleaning results.
