What robotic cleaner do you recommend? Roborock Q7 Max+ or Q Revo Curv for a three-bedroom apartment with kids and pets?

To give a proper recommendation, it is essential to understand your budget. The prices for these models differ significantly. Also, Q7 Max+ has medium suction power, and the docking station only empties the dust bin, while Q Revo Curv has the highest suction power on the market, and its base station can refill water, empty the dust bin, wash and dry the mopping pads.

There are many other differences in brush rolls, extended mopping pad and side brush, smart features, and runtime that are better for Q Revo Curv. However, if we compare Q7 Max+ with robots from the same price category, Roborock will be one of the best models.

Do I need to buy this model if my floor surface is more than the cleaning area indicated in Roborock Q7 Max+?

The cleaning area that I indicate is the maximum area that the robot can clean in quiet mode (in the minimum suction power and water level for mopping). In auto mode, the cleaning area will be smaller, especially if you have a lot of carpets (carpets are cleaned with maximum suction using carpet boost) and many tough stains. If your floor surface is higher, the robot will automatically go for recharging and resume after. Correspondingly, the cleaning cycles increase to 5-6 hours, including recharging. If it is okay with you, you can purchase Roborock Q7 Max+.

How can I use the intelligent emptying modes of Roborock Q7 Max+?

This function is very useful if you set it to clean while you are sleeping. Also, you can adjust the emptying based on your cleaning habits and the quantity of dust. In general, emptying the dustbin is a loud process but lasts only a couple of minutes.

The docking station of Roborock Q Revo Curv is very small compared with other models. How could this be?

Even though the Roborock Q Revo Curv base station's functionality is good, it has compact sizes, as it uses several advanced technologies—dust compression to make the dust bag a minimum size and the optimal size of clean water tanks for washing pads and refills. I want to assure you that the sizes are enough for several weeks of hands-free maintenance.

Do you recommend purchasing the used robotic vacuum cleaners?

If you are short on money and find a seller with a warranty for the cleaner, this could be a good way to save money. Amazon sells used models for attractive prices. But you can also purchase the robot on sale for a close price, and it will be a new model.
