Key Features to Consider when Buying a Window Vacuum Cleaner
Just like any other home appliance, there are several features that you need to consider before buying a window vacuum cleaner. Here are two key elements that you need to consider the most.


Because most window cleaners are cordless, you need to be very wary of the run-time. Most cleaners will have a run-time of 20-45 minutes. When choosing a cleaner, go for one that will allow you to clean your windows and other surfaces efficiently, without needing to recharge.

Accessories and tools

Your window vacuum cleaner should be able to support some accessories and tools. Of course, these are not essential features. However, getting a vacuum that comes with some accessories and tools can help make your work so much easier. Some of the accessories include a spray bottle kit, extension poles, and narrow suction heads. These accessories can also be bought separately. However, this option may be more expensive, and you are better off getting a cleaner that comes with some of the accessories.
