Excellent for removing dirt, cleaning agent residue, and other remnants, this vacuum will give you a gleaming home in no time. The brilliant suction power allows for a non-drip, streak-free finish.

Capable of vacuuming water away at all angles, with absolutely no leaks to worry about, this Leifheit window vac can work on glass, tiles, and mirrors, as well as your windows.

9. Prostormer Cordless Set (No Drip Option)

Prostormer Cordless SetThe Prostromer Cordless Window Vac Set is lightweight and easy to use. It is also highly effective and makes cleaning much easier and faster when compared to other simpler cleaning products and accessories.

Prostormer window vacs feature a drip-free, cordless design and come with a USB charging cable. The rechargeable battery takes two to three hours to reach a full charge, which is typical for these tools. A full charge gets you about 30 minutes of runtime, which should be long enough to complete small to medium-sized cleaning tasks.

The restrictive battery life on this device means it is not the best option for larger applications. We also think the instruction booklet included leaves something to be desired. And heads up, the plug adapter required for charging is not included with your purchase.

  • Window vac and spray bottle set
  • Lightweight and easy to use
  • Cordless with a rechargeable battery
  • Flexible heads for a better clean

The Tower RWV20 Cordless Window Vac features a 150 ml water tank capacity and a 30-minute runtime with each full charge. Its battery takes about 3 hours to fully charge. The water tank is also easy to fill and refill and has a fairly transparent cover so you can easily see the water level and prevent it from accidentally running dry.

Each of these window vacs comes with a spray bottle attachment as well as an absorbent microfiber cloth attachment. Combined with the window vac itself, these attachments allow you to clean a variety of surfaces effectively and efficiently.

Regretfully, this device may be somewhat less durable than other, more robust window vacs. In addition, it could leak a small amount of water if you try using it at a sideways angle. In addition, the device is a bit bulkier than some other popular options. However, considering the large water tank, this is not surprising.

Just as you would with carpet cleaners, steam cleaners and cordless vacuums, finding the best window vac that fits your cleaning routine means thinking carefully about the specific capabilities you’re going to need.

Whether you’re looking for the best steam window cleaner or just something simple to save you some extra time, here are some tips to help you make the right decision.

1. How Easy Is It to Use?

Most window vacuums available today are cordless, which means that you won’t have to worry about tripping over a wire while you clean. However, there are other things that can affect how easy it is to use your new device too. For instance, let’s look at some questions you might consider.

  • Are there extensions available so you can reach difficult areas?
  • Will the window vacuum leak if you use it at an angle?
  • How heavy is it? Do you get an ache in your wrist while using it?

The easier it is to use your new window vac system, the less likely you are to rush when you clean your windows and end up with a bad result.

2. How Efficient and Versatile Is It?

cleaning up a windowAside from being easy to use, your window vacuum also needs to deliver an efficient and versatile clean. One of the first things you’ll need to look at here is how much battery life you can expect to get out of the product. Most window vacs will give you at least 25 minutes of run time in between full charges. However, it’s always worth checking the reviews of the window vacuums you are considering. Try to see if there are any feedback about how they start to lose their suction power when it needs to be recharged.

Additionally, think about how versatile the cleaning system is. Many of the window vacs on the market today come with different cleaning heads so you can tackle a wide variety of flat surfaces. You should be able to clean everything from tabletops to tiles without breaking much of a sweat. Consider the accessories that come as standard and how easy it will be to get into tight corners and difficult to reach places with the vac you’re choosing.

3. How Good Is the Clean?

The main thing that most homeowners want from a window vacuum is the promise of a streak-free clean without the elbow grease. That means that the quality of the clean should be a priority when you’re choosing the model you want to buy.

The best window cleaner will be one that gives you great results the first-time round, so you don’t have to keep scrubbing the same spot over and over to get rid of streaks and spots. Today, many window vacuums come with microfibre cleaning features and multiple blades so you can improve your chances of a great result.

If you’re looking for extra assistance in your housekeeping routine, check for window vacs that come with the option to turn up the suction power on tricky smears and stains. You can also check that the model you choose comes with a strong spray bottle.

4. Are There Any Accessories?

Finally, as the window cleaning market becomes more competitive, some manufacturers are beginning to invest in additional premium accessories to attract a greater number of customers. For instance, some window vacs come with an easy-to-clean water tank that can save you some valuable time between sessions. Other companies include special solutions with their vacuums to give you a head-start on your cleaning strategy.
