Roborock Qrevo S

Roborock Qrevo S is a further development of last year's hit Qrevo model and offers a range of improvements that make it even more versatile and powerful. One of the most prominent updates is the increased suction power, which allows the Qrevo S to efficiently handle both large and small debris on different types of flooring. The dust container has also been given a larger capacity, which means it can collect more dirt before it needs to be emptied, minimizing maintenance for the user.

Another important improvement is the introduction of hot air drying, which effectively dries the mops after cleaning, preventing unwanted odors and mold formation. The 30% faster charge allows the Qrevo S to be quickly ready for the next cleaning session, which is especially useful in larger homes or if you have many rooms to clean. The removable base is a smart novelty that facilitates cleaning and maintenance, while the automatic tank filling to the base station minimizes maintenance for the lazy.

The navigation system in the Qrevo S is both precise and reliable, allowing it to maneuver smoothly around obstacles and furniture, while mapping your home to optimize the cleaning route. The integrated Wi-Fi connection and app control give you full control over cleaning right from your smartphone, where you can easily schedule cleaning times, adjust settings and follow the vacuum cleaner's progress in real time.

With a powerful 5,200 mAh battery, the Qrevo S offers up to 180 minutes of operating time, which is more than enough to cover large areas without having to return to the base station to recharge. In addition, it has dual rotating mops that spin at 200 revolutions per minute to remove even the most stubborn stains, and these mops can be automatically lifted when the vacuum cleaner detects carpets, to avoid wetting them.

In summary, the Roborock Qrevo S offers an excellent balance between advanced features and ease of use, making it an attractive option for anyone looking to invest in an affordable robot vacuum cleaner. Given its improved performance, expanded functionality and competitive price, Qrevo S is a strong choice for anyone looking for a reliable and smart solution to keep their home clean and fresh.
