How to choose a window cleaning robot
There are magnetic and vacuum models of window cleaning robots on the market today.
The magnets are made up of two parts. Each part is installed on both sides of the glass and is magnetized to each other. Accordingly, with the help of such a robot it is impossible to clean mirrors and tiled walls – it simply cannot be fixed. Also, magnetic washers have limitations on the thickness of the glazing: before buying, it is important to make sure that they are suitable for your double-glazed window.
The vacuum ones are held on the glass with a vacuum pump. They are more versatile: suitable for mirrors and walls. And there are no restrictions on the thickness of the double-glazed window.
As a result, due to their advantages, vacuum models almost completely replaced magnetic models from sale. We recommend choosing a vacuum window cleaner.
Popular questions and answers
The KP answers frequently asked questions from readers Maxim Sokolov, expert of the online hypermarket “VseInstrumenty.ru”.
What are the main advantages of square window cleaning robot?
Another important point is the equipment with glass edge detection sensors. Thanks to them, the square robot instantly changes the direction of movement as soon as it approaches the “abyss”.
Oval robots do not have such sensors. They change direction when they hit the frame. If there is no frame, a fall cannot be avoided. That’s why oval models are not suitable for working with frameless glazing, glass office partitions or for washing tiles on walls that are not limited by internal corners.
What are the main parameters of square window cleaning robots?
Form. The advantages of square models have already been mentioned above. Ovals also have their advantages. Firstly, their cleaning wipes rotate, so they are better at removing stubborn dirt. Square models have such a function – a rarity. Secondly, oval models are more compact – if the windows are small, only they will fit.
Management. Usually, more budget models are controlled by a remote control, more expensive ones – by an application on a smartphone. The latter benefits from more settings and the ability to give commands from another room.
Power cord length. Everything is simple here: the larger it is, the less problems with choosing a suitable outlet and washing large windows.
Battery life. Robots equipped with batteries are on the market. However, it is important to understand here: they still need to be connected to the outlet. The battery in this case is insurance. Imagine that there is a power outage. Or someone accidentally unplugged the robot from the outlet. If there are no batteries, the robot will instantly turn off and hang on a cable. The battery will eliminate such a situation: for some time the robot will stay on the glass. The duration of this time depends on the capacity of the battery.
Equipment. The more different napkins and attachments, the better. I also advise you to immediately check if there will be any problems with the purchase of consumables for your robot. Make sure they are available for sale
