Appearance
The Xiaomi Mijia Hutt W66 window cleaner is made of modern white ABS plastic. Its square body has compact dimensions of 231.5 x 231.5 x 76 mm. It weighs 1.57 kilograms.
The front panel of the window cleaning robot features two plastic recesses for a comfortable grip when carrying it. Near the center is an LED indicator that lights blue when the device is activated. The mechanical buttons are positioned so that the device can be operated with one hand.
The Xiaomi Mijia Hutt W66 window cleaner has sensors on the end that detect obstacles and edges of the surface being cleaned. If any are detected, the window cleaning robot will slow down as much as possible and change its direction.
What do we see when viewing the device from the back? It features tracks made of high-tech polymer with a sophisticated design that eliminates the risk of towing, jamming, or getting stuck. Furthermore, the wheels leave no marks or streaks. The base of the window cleaning robot also features a sliding power switch, fall protection sensors, and ventilation holes. The ventilation holes on the base and sides of the window cleaner ensure timely cooling of the hot components.
However, the robot's main feature is the nozzles for wetting the cloth and surface, which are located in the front part. With their help, the window cleaner removes dirt more effectively. A similar design solution has been implemented in Hobot 298 Ultrasonic, which we discussed earlier.

Functional capabilities

The window cleaner features several operating modes, each with a different cleaning path. The device can be controlled using either the included remote control or a smartphone app. Both options are convenient.
As we noted earlier in the review, the window cleaner slows down and changes direction when approaching the edge of a surface. Therefore, it can be safely used for cleaning frameless glass.
The Xiaomi Mijia Hutt W66 is equipped with a sprayer and a 150-milliliter water tank. This capacity is sufficient for cleaning surfaces of 70-80 square meters.
In addition, the device is equipped with an advanced suction system, ensuring complete adhesion to any surface (both smooth and rough). This system, combined with a sophisticated cleaning algorithm, guarantees the most effective cleaning without scratches or other damage. The window cleaner is capable of handling dried-on stains, sand, bird droppings, and more.
The manufacturer also provides an automatic increase in suction power when detecting dirt on the glass.

Hello. The article states, "The device can be controlled either with the included remote control or via a smartphone app. Both methods are convenient." Could you tell me which app controls the robot and how to find it? Mi Home can't find it. Apps from the Play Store don't work. Thank you in advance.
