10. Roborock S6 MaxV:

The Roborock S6 MaxV is a really good robotic vacuum cleaner that both mops and vacuums. Overall, we’re quite happy with it, but less so with Xiaomi’s model strategy.

Roborock S6 MaxV review

The Roborock S6 MaxV is the top model of the company. That’s fine, but at the same time, Xiaomi is releasing a new top model in the old S5 series, which in some respects – mainly the mop function – is better than the S6 Pure. We think this isn’t very clear and not very logical.

There are some problems with corners and edges, where you might find a bit of dirt gets left behind. But for the most part, it works both reasonably quickly and efficiently. We also notice that it’s significantly more stubborn than many other robotic vacuum cleaners. It tries to get over thresholds, carpet edges and similar obstacles that are a little too high from all possible angles – and usually succeeds. 

The same also applies when it’s found its way under a chair or into a corner. It tries out all the angles to escape before asking you for help.

Our Verdict:

We have tested almost all the best vacuum cleaners that are among the best robot vacuum cleaners of 2021. We conclude that different companies use different technology in their vacuum cleaners. For example, many vacuum cleaners use their camera while others use their laser or infrared technology to do the cleaning. Some of the models work with the predetermined pattern dividing the rooms into several cleaning zones. And others work on an algorithm which involves random movement combined with this zone division. In this article, we studied how the best robot vacuum cleaners clean the house and the amount of time they took to do so in a single charge. We also investigated how easy it is to clean the dust collector of the vacuum cleaner. Most of the vacuum cleaners have docking station powered by the primary adapter, and all models are wireless. 

For the best results, Xiaomi Today recommend the customers to run robot vacuum cleaners for three to four days a week. It’s also good to sometimes supplement this with regular vacuum cleaning and cleaning with a microfibre cloth in the corners of the room and on skirting boards. But thanks to robotic vacuum cleaners, the process of keeping your floor clean has never been easier.
