      How to choose window cleaning robot?

      To choose which is the best robot for cleaning windows for you and your home, we tell you what aspects you should consider when buying. 

      Cleaning system

      These appliances work mainly with the following cleaning systems: brushes, microfiber cloths, or pads. You can also find models on the market that include other features such as rinsing and drying.

      Usually, when buying the robot, several spare pads are included, and in most cases, they are reusable, which is good for the environment.

      On the other hand, some more modern models have a vibrating function, which is ideal for removing stubborn, dried dirt on the glass.

      Cleaning programs

      Cleaning programs are an essential aspect to consider, as cleaning efficiency depends on it.

      Most of these devices usually have 2 different cleaning methods: one for dry cleaning and another for wet cleaning with suitable liquids for this.

      They offer 3 cleaning programs as standard: vertical, horizontal and mixed. The modes can be combined with the navigation function or AI technology (artificial intelligence) so that you can calculate the most appropriate route and not worry about edges, corners or frames.

      Some models also offer additional programs as a repeat function. This causes the robot to clean the surface twice in a row to perform a much deeper cleaning and remove any dirt.

      It is essential to consider what type of surface you want to clean because it will also depend on whether you need more or fewer programs available.

      Power

      In general, the power of most window cleaning robots is usually between 70W and 80W.

      It is essential to pay attention to power because this will determine the machine’s efficiency. Also, the power is used to calculate the approximate power consumption of the electrical appliance. 

      Cleaning speed

      Undoubtedly, we are in a time when we are all looking for fast results, so it is not surprising that we demand it from our devices as well. For this reason, it is good to choose a model with the highest possible cleaning speed, as this way you can save a lot of time.

      It would be good to choose a model with a speed of 1 square meter for 4 minutes in the worst case. If you want a faster device that cleans at a higher speed than this, you must keep in mind that the price will be significantly higher.

      Knowing the speed at which the appliance cleans, you will be able to calculate the time required to complete the task at home.

      Some models also allow you to adjust the cleaning speed, as it more or less depends on the cleaning surface and the user’s preferences.

      Fastening

      Typically, most modern window cleaners have two fastening systems: magnets or vacuum.

      • Magnetic system:  Devices with this mounting system use these magnets to adhere to the glass and keep the device in place. These magnets are placed in two different parts. One is responsible for cleaning, and the other holds the appliance attached to the glass.
      • Vacuum system:  Other models have a system that works thanks to a motor that creates a powerful vacuum. Thanks to this, the robot can stay snug without falling. One of the biggest advantages of this system is that it can be placed on any glazed surface, regardless of its thickness.

      Navigation system

      When we say that a robot for washing windows has a navigation system or AI technology (artificial intelligence), it refers to how it moves on surfaces. Thanks to the algorithms available to the robot, it can calculate the ideal cleaning route. It also detects the boundaries of windows or other surfaces to be able to clean them thoroughly.

      In other words, these devices have sensors and detectors capable of scanning the surface they need to clean. This allows them to detect obstacles, edges, frames and corners. As a result, they can act in a way that they avoid or bypass and recalculate their movement accordingly.

      Mid-range or high-end models may even have a zone memory system. It allows them to track routes in different ways and return to the starting point when they have finished their work so that we can download them conveniently and quickly. In this sense, they work in the same way as robot vacuum cleaners.

      Control

      In general, most window cleaning robots have two ways of control. One option is through remote control, where all functions are configured; or through an application that you can install on your smartphone.

      In case it is essential for you to be able to control it from your mobile phone, it is essential to make sure that the offered mobile application is available for the mobile operating system of your smartphone (Android and iOS are the most common).

      Safety

      Window cleaning robots work glued to the glass, so there is always a chance that they will fall if their vacuum system fails. For this reason, it is essential to make sure that you choose a model that has a good security system to avoid any accident.

      Most models are equipped with at least a safety rope to prevent the device from falling, injuring someone, or breaking. These ropes are usually quite strong. Most can withstand up to 150 kilograms in weight and are generally approximately 5 meters long. 

      Another safety system that some models have is the one that comes with ultra-resistant suction cups, which, thanks to their powerful suction pump, adhere perfectly to all glazed surfaces. 

      Ideally, you should check to see if there is an emergency battery that activates automatically in the event of an unforeseen power outage. This allows the appliance to run long enough for you to complete the washing or to remove it. Manufacturers usually include lithium batteries, which have good battery life.

      Autonomy

      Most models are powered by a cable that connects to the outlet. To maintain a constant power supply, many of these window cleaning robots have a spare battery that turns on in a power failure or power outage. If the robot you choose has a spare battery, this will prevent it from falling off the glass.

      In terms of autonomy, the battery usually lasts up to 20-30 minutes. This is enough time for the robot to finish cleaning or to prevent it from falling and breaking.

      On the other hand, it is good to know that there are wireless robots for cleaning windows on the market. In case you prefer to buy a wireless model, you should check very well what is the autonomy of its battery. As a general rule, most wireless models usually have durability quite similar to a backup battery, i.e. between 20 and 30 minutes. Therefore, keep in mind that you will be able to clean between four and six medium-sized windows with one charge before you have to recharge the device’s battery. Of course, if you find a robot with more autonomy, it will most likely be at a higher price.

      For this reason, it will be essential to determine the number of windows or windows that will be cleaned and how often so that you can find a model with a battery according to your needs.

      Noise level

      As for the noise level of the window cleaning robot, it should be as low as possible to avoid discomfort while working. It is recommended that the noise level does not exceed 74 decibels.

      Although these devices are designed to facilitate long and tedious task, this does not mean that we should be satisfied with just that and that we can not require some features that provide us with even greater comfort. For example, to be as quiet as possible while cleaning so that we can work, read or watch TV without any worries.
