The Best Robot Window Cleaners of 2021: 5 Square and 3 Oval-Shaped

Hello to all site readers! This article will review the best window cleaning robots of 2021. This rating is not much different from last year's, as the robotic window cleaning market is less dynamic compared to robotic vacuum cleaners. However, in late 2020 and early 2021, several interesting new products emerged and took their place among the top performers. Below, we'll look at the five best square-shaped window cleaning robots, which are best suited for medium and large windows, as well as three oval-shaped robots, also known as round ones due to the shape of their cleaning pads. These, in turn, are best suited for cleaning small and medium-sized windows. So, let's get started!

Top 5 Square Window Cleaning Robots

Hobot 298 Ultrasonic

Opens the top five best square window cleaning robots Hobot 298 UltrasonicThis model has been actively sold since 2019 and has garnered numerous positive reviews online.

A unique development at the time, incorporated into the 298 model, is a cleaning fluid reservoir with an ultrasonic sprayer. This technical solution allows the robot to automatically wet the window during operation, increasing the effectiveness of dirt removal. The Hobot 298 is controlled by both a remote control and a mobile app. The robot is suitable for cleaning windows no smaller than 40 x 40 cm. Its design also allows it to clean frameless windows, as well as any other vertical surfaces, such as mirrored wardrobe doors or tiled walls. It features six operating modes and an emergency hold time of 20 minutes after disconnecting from the power source. The average price is $300.

Bist Win A100

The rating of window cleaning robots continues with an equally interesting model - Bist Win A100The cost is also within $300.

In fact, this robot is on par with Hobot in terms of functionality and window cleaning quality. It features a unique window cleaning system based on a small moving platform that, when the cleaner moves, mimics the motion of a human scrubbing hand. A second platform, with a cloth attached, is stationary and collects the bulk of the dirt and dust.

The Bist Win A100 is controlled by a remote control. Its minimum window size is 40 x 50 cm. This robot can clean not only windows but also other vertical surfaces, such as mirrors, glass doors, and tiles. Its battery-powered emergency runtime lasts up to 30 minutes, enough to remove the robot from the window in a timely manner. Reviews are overwhelmingly positive; the brand has been on the market for quite some time, and the robot itself has been actively selling for over two years.

iBoto Win 289

The bronze medalist of our ranking is iBoto Win 289Its price is almost half as cheap and ranges from $170 to $190.

The design is standard, and the window cleaning quality is good. It can be controlled via a remote control and a mobile app. Furthermore, the robot can operate autonomously for up to 20 minutes when unplugged. It's also important to note that the minimum window size for this model is 35 x 35 cm.

Overall, the iBoto Win 289 is a more affordable window cleaning robot, but it's definitely one of the best. We tested it and have no complaints about its navigation or window cleaning performance, so we can confidently recommend it.

Atvel Zorro Z5

The top five best square robotic window cleaners of 2021 included another rather interesting device called Atvel Zorro Z5The robot's main advantage is its compact size, which allows it to easily clean narrow vertical windows and even vents. Furthermore, thanks to its low height, it can even clean windows with bars.

We reviewed this window cleaning robot and found it to be well-guided, fast cleaning, and of high build quality. We also appreciated the Atvel Zorro Z5's ability to work on horizontal surfaces, its control not only via the remote control but also via the proprietary mobile app, and its ability to clean frameless windows. Additional advantages include a warranty and service support, as well as a battery life of up to 40 minutes, allowing you to promptly remove the robot from the window in the event of a power outage. Overall, the Atvel Zorro Z5 is definitely one of the best window cleaning robots available and definitely deserves your attention!

Genio Windy W250

Well, and closing out the TOP-5 square robotic window cleaners is another new product of 2021 - this Genio Windy W250This robot is a copy Hutt W66, with one important advantage: Genio is officially represented on the market and provides a warranty and service for its products. For many, this may be a significant advantage when choosing between the Genio Windy W250 and the Xiaomi Hutt W66.

The Genio Windy W250 window cleaning robot is equipped with five water spray arms at the front and a 150 ml tank. During operation, the robot automatically sprays water onto the glass and wipes the surface with a cloth. The Genio Windy W250 features four operating modes and is controlled via a remote control. Window cleaning quality is excellent. Sales are scheduled to begin in May-June 2021. Pricing is currently unknown.

Top 3 Window Cleaning Robots with Round Cloths

Now that we've covered square window cleaners, let's move on to a review of the three best oval-shaped models. There's no point in reviewing any more models, as there aren't many worthy options of this design on the market, so in this ranking, I'd like to highlight only the best robots. There are window cleaners on AliExpress for around $100, but they're unlikely to provide good cleaning performance or last long, so I can't recommend them at this time. Let's talk about the leaders.

Hobot 388 Ultrasonic

Opens the rating Hobot 388 UltrasonicLike its square counterpart, it is equipped with a cleaning fluid reservoir with an ultrasonic sprayer.

The robot has a stylish appearance and an ergonomic design. Cleaning pads extend beyond the edges of the body, allowing the robot to better clean windows along the frames. The minimum window size is 35 x 35 cm. It also features 6 operating modes and can be controlled via an app or remote control. The battery life is up to 20 minutes. We reviewed the Hobot 388 and received a mostly positive review. The price at the time of writing was $290.

iBoto Win 389 Ultrasonic

The silver medalist of our TOP-5 is the new 2021 product iBoto Win 389 Ultrasonic.

Like Hobot, it features a sprayer that automatically wets the surface with wipes before cleaning. The robot is suitable for cleaning a variety of vertical surfaces: not only windows, but also mirrors, glass doors, and tiled walls. The battery lasts for 30 minutes in emergency mode. The window cleaning robot is controlled both by remote control and via a proprietary mobile app. Sales are scheduled to begin in May 2021. The estimated price is approximately $190.

Genio Windy W200

In the line of robotic cleaners with round cloths, Genio has another worthy device - Genio Windy W200.

It's basically the same Xiaomi Hutt DDC55, but again, it comes with a full warranty and after-sales service from the manufacturer. The price is roughly the same – around $175. The robot features several cleaning modes and a built-in battery that provides fall protection for 20 minutes after a power outage. The Genio Windy W200 is controlled by a remote control. Window cleaning performance is excellent, as is the build quality. Reviews are generally positive, so this model is definitely worth considering.
