Robotic window cleaners make it easy to clean windows indoors and outdoors, including those that are difficult to access. A window cleaning robot usually cleans a whole window from edge to edge, alerting you when it's finished.
Robotic window cleaners combine automated movement with window cleaning technology, and they usually stick to windows using motor-powered suction. Once stuck to a window, they can automatically clean the window from edge to edge, allowing you to clean high, out-of-reach windows. Window washing robots like the Winbot 730 and Hobot 168 offer automated window cleaning on most types of windows, including high ones.
While most window washing robots offer the same general features, some provide different functions, cleaning methods and height restrictions.
Robotic Window Cleaners: What to Look For
The features you need will depend on how much window surface you want to clean at once. You should also consider whether you want a purely automated robot or one with a remote control, as well as how long you want the robot to run between charges. The following features are all considerations to keep in mind.
Most window cleaning robots have a short battery life that allows them to clean 10 or more windows on a single charge. This might mean you get a battery life of less than 15 minutes or over 30 minutes depending on the model. The more windows you have in your home, the more valuable a longer battery life is. However, models with longer batteries usually cost more.
Suction or Magnetic Connectivity
There are two main types of connectivity found in robot window cleaners: magnetic connectivity and motor-powered suction. Magnetic connectivity usually requires you to attach a second magnetic piece on the opposite side of the window, which may be difficult in some cases. Motor-powered suction is more convenient because you only have to place the window washing robot on the window. However, this type of connection might sometimes fail, so you need a safety cord to keep the window cleaning robot from falling.
Most window washing robots use cleaning pads or brushes to clean, but many also use a drying feature such as a squeegee to ensure that the window is streak free. The number of brushes and pads can vary depending on the model. You might also have to fill the model up with a window cleaning fluid before putting it out. A two-step cleaning process usually involves wiping away dirt and then polishing the window. Some also feature brushes for cleaning other surfaces, such as shower walls, doors and mirrors.
Remote Controls & Automated Cleaning
Window washing robots come with both automated cleaning options and remote controls. While not all options include both, automation allows you the convenience of sitting back while your windows are cleaned. A remote control enables you to steer the robot around the window. Some models include both control options for versatility, allowing you to choose.
While there are several robotic window cleaners available, you can choose yours by deciding what you want it to do and finding the features that suit your needs. Read more about the Winbot and Hobot below.
The Winbot 7 Series W730 is a window washing robot with a two-step cleaning process, two cleaning pads and a squeegee for drying the window. While the motor-induced suction may occasionally fail, the window cleaning robot features a safety line to prevent it from falling.
A motor-powered suction system allows the window cleaning robot to stick to any thickness of glass including glass doors, mirrors, tall multi-story windows and even very large windows. The suction system means that the window cleaning robot does not work on beveled or concave windows because it cannot create a strong seal. While it's not battery operated, the robot window cleaner comes with several lengths of extension cords, allowing you to clean most window heights.
The robotic window washer immediately sticks to the surface you place it on, and then starts cleaning with the push of a button. It uses a three-phase cleaning process with cleaning pads and cleaning fluid to wipe off dirt and then a squeegee to dry the surface to prevent streaks and then wipes the surface down with a clean pad. The three-part cleaning process mimics the cleaning process most human cleaners use. However, it may leave streaks if the cleaning pads are dirty. While the window washing robot cleans large windows, it does not work with windows that are smaller than 18 inches wide and 24 inches tall. This is because the sensors allow it to run at least that far before stopping. The automatic sensors allow it to detect edgeless windows and window edges so that it cleans to the end of the window and no further. You can also use the included remote control to steer and control the robot as needed. The battery lasts for approximately 15 minutes, or enough time to clean up to six medium to large size windows.
When finished, the robotic window washer plays a tune to notify you. Then you can turn the suction off by flipping a switch so that you can remove the robot from the window. Because the Winbot returns to the area where it was originally placed on the glass, you can use it on tall windows where you cannot reach the top as well as outdoor windows that are difficult to reach without a ladder.
The Winbot W730 offers automated window cleaning for large and tall windows but has a limited battery life, does not stick to all surfaces and goes through cleaning pads quickly.
The Hobot 168 is an environmentally friendly robotic window cleaner that can also be used to clean tables. It uses motor-powered suction to remain attached to the window while in use, but also has an anti-dropping system to prevent it falling in the event of a power failure. This smart device offers multiple operation modes for enhanced user control.
Because it is single-sided, the Hobot window washing robot has no maximum thickness restrictions, so you can clean any window more than 3 millimeters thick. This model has an internal battery pack that you charge via the provided cable. You can also plug in the included power cord and use the window cleaning robot while it charges or directly from the home electricity supply. An LED flashes orange while the window cleaner charges and another LED flashes green when the battery reaches full charge.
The Hobot 168 has a vacuum motor that draws in air and allows the window cleaning robot to hold onto the glass as it traverses the surface. To stop this small smart appliance from falling if the battery cuts out or the power fails, it has an uninterrupted power supply and an anti-dropping algorithm. Additionally, it has a high-strength safety rope that you attach to a suitable pole or ledge before use. It uses cleaning wheels that can cross both glass and stonework for full window coverage.
For increased versatility, the device features three different automatic modes that you can program and adjust via the included remote control, as well as a manual option. Additionally, this robotic window cleaner can be set to "table" mode, to clean tabletops. With the automatic modes, the Hobot uses a variety of sensors to detect window frames and obstacles and to plan a cleaning route, so it can quickly and efficiently clean an entire window surface automatically. The micro-fiber cleaning pads are machine-washable and are quick to change, negating the need to regularly buy new pads.
The Hobot 168 is suitable for most domestic and commercial window cleaning tasks and has three distinct automatic modes, as well as a manual setting, so it is a versatile smart device. The cleaning pads require changing regularly but are machine-washable, and for further convenience, the machine also cleans tabletops. This model has an array of safety features to limit the risk of it accidentally dropping from the window.
