Wolkinz Cosmo

In 2018, the robot vacuum cleaner market was replenished with another interesting model from the German company Wolkinz Electronics – the Wolkinz Cosmo. This device is suitable for dry and wet cleaning of smooth floors, as well as for cleaning low-pile carpets. Like all modern household robots, the Wolkinz is controlled via a mobile app, maps the room using a laser sensor, and can operate on a preset schedule. Below, we'll provide a detailed review of the Wolkinz Cosmo, examining its specifications and features.

Appearance

The Wolkinz Cosmo robot vacuum cleaner was developed by German engineers, and its design is truly space-age. The first thing you notice is the laser radar, mounted in the center of the top of the body. It navigates the robot and maps the room. The body itself is made of durable plastic, with a glossy black top. Next to the radar, you'll find the Wolkinz logo, an indicator light, and the robot vacuum's only control button.

The front, like most household robots, features a movable bumper (shock sensors) and ultrasonic sensors. The rear houses the charging contacts, support brackets, and ventilation holes.

If you turn the robot vacuum upside down, you'll see two side brushes, an on/off button, drive wheels, an auxiliary wheel, a swivel wheel, and height sensors. The suction port, which enables dry cleaning, is also located there. Please note that the Wolkinz Cosmo's dust bin is located at the bottom, unlike most robots (the lid usually opens from the top). This location is more convenient, as removing it for emptying prevents debris from spilling onto the floor.

Functional capabilities

Let's begin our feature description by examining the Wolkinz Cosmo's cleaning principle. The robot vacuum cleaner is equipped with two side brushes that collect small debris and direct it into the suction port. Testing showed that the robot is capable of picking up small debris, as well as pet hair and fur. The side brushes are effective at picking up debris along baseboards and in corners, and the rectangular shape of the robot's front section also helps ensure thorough cleaning of corners. The manufacturer provides a wet cleaning function; to do this, simply place the cleaning unit with a cloth on the bottom. Water is easily added to the unit by opening the sealed valve. The capacity is sufficient for one full cleaning cycle.

When it comes to navigation, the engineers certainly did a great job. The robot vacuum cleaner is equipped with a military-grade laser radar, also known as lidar. This technology allows the Wolkinz Cosmo to map the room and automatically select the optimal navigation algorithm. The entire route is displayed in real time in the dedicated WZ COSMO app (using MapVision technology), allowing you to see where the robot vacuum cleaner has and hasn't cleaned yet. When the battery runs low, the device automatically returns to its base, recharges, and then resumes cleaning from where it left off.

It's worth noting that the Wolkinz Cosmo is equipped with a high-power inverter motor, backed by a lifetime manufacturer warranty. As noted in the specifications, the suction power is 1600 Pa, which is quite high; the average suction power of robotic vacuum cleaners ranges from 800-1000 Pa.

The mobile app deserves special attention. It's available for Android and iOS. You can download it from the manufacturer's website or from an app store. The robot vacuum is controlled via the mobile app, which requires syncing with the Wolkinz Cosmo via Wi-Fi. The app is simple and intuitive, despite being in English. The app's features are standard, but sufficient: you can program a cleaning schedule, track the robot vacuum's route, switch modes (increase or decrease suction power), and return the robot vacuum to its base.

The Wolkinz Cosmo's quiet operation allows you to go about your daily business while the robot vacuum cleans. The device is equipped with a notification system and an indicator that displays the robot's status and alerts you to any errors. It also includes a magnetic strip, allowing you to restrict the robot's cleaning area. For example, it's very convenient for preventing the Wolkinz from running over high rugs or protecting pets' food dishes.

Advantages and disadvantages

Let's summarize our review and highlight the main advantages and disadvantages of the Wolkinz Cosmo. Among the positive aspects, we would like to highlight:

1. Stylish and modern appearance.
2. Good quality of assembly and materials.
3. Rectangular body shape for thorough cleaning of corners.
4. The Walkins robot is capable of dry and wet cleaning.
5. The quality of dry floor cleaning is at a high level.
6. The kit includes all necessary elements.
7. Good battery capacity.
8. Possibility of control from a smartphone.
9. Navigation is at a high level: there are no problems with finding a base or building a map of the premises.
10. The robot vacuum cleaner is capable of cleaning large areas of the room.
11. High suction power.
12. Capacious dust collector.
13. The robot vacuum cleaner comes with a 3-year warranty.

There are some disadvantages, but they are not that significant:

1. There's no remote control included. Although the Wolkinz Cosmo is controlled via phone, a remote control is sometimes necessary.
2. The glossy surface is quite difficult to maintain, leaving marks when touched.
3. The robot vacuum cleaner struggles with high-pile carpets. While this is a problem with all robot vacuum cleaners, they are generally better suited for smooth floors.

Overall, the model is quite interesting. Despite its drawbacks, the Wolkinz robot meets all the criteria for premium models. It's worth noting the relatively high price of the device, which in 2018 was $450. However, considering all the functionality, specifications, and build quality of the robot vacuum, it's understandable why it's so expensive. This concludes our review of the Wolkinz Cosmo.
