I see that the Roborock Q Revo Curv has a water tank – 80 ml, while the Dreame L40 Ultra has 200 ml. Is it bad?

The water tank capacity in the tank does not impact significantly. As mentioned in the comparison robotic vacuums go with a base station with automatic refilling. That means when the water tank is empty, the robot automatically goes to the station for refill. While the robot stays in the station, it always empties its dust bin, and hot water washes the pads.

In such a case, your pads will be fresh during the whole cleaning. If you do not need the washing and emptying function during refill, you can adjust the settings in the smartphone app. So, please do not neglect Roborock Q Revo Curv for the size of the water tank.

Is it true that the suction power of 18500 Pa is the highest on the market now? Does this mean that Roborock Q Revo Curv is the best robotic vacuum cleaner?

Roborock Q Revo Curv has obtained in 2024 the highest suction hyperforce power that allows it to pick up and capture all types of dust, including fine dust, coffee grounds, and pet hair. However, the suction power is not enough to consider the robotic cleaner the best; there are many other important features.

Among them are a multi-functional docking station, tangle-free main and side brush, rotating mopping pads, smart control of the robot, and a precise navigation system. All these features, plus a flex arm side brush and mop for cleaning hard-to-reach corners to cover up to 100% of the floor, make this model almost unbeatable on the market.

How is it possible that the Roborock Q Revo Curv has a 6400 mAh battery that charges for 3 hours, while the

Dreame L40 Ultra has a 5200 mAh battery that charges for 4 hours?

What does multi-floor mapping mean for Dreame L40 Ultra and Roborock Q Revo Curv?

Both robots rapidly create maps for up to four floors. The maps are automatically recognized, and you can set no-go zones if necessary to protect some areas. But as the robot can’t climb and go down the stairs, you need to manually move robots between floors.

Can you please compare the main brush rolls of these two robots?

Dreame L40 has a unique TruCut Roller brush; it consists of a rolling brush to cut hair automatically, plastic bristles to pick up dust, and a long rubber fin. This brush roll is recommended for houses with pets and carpets.

The brush roll should be replaced every 3-6 months, depending on the usage frequency. Roborock Q Revo Curv consists of two parts rotating in different parts to minimize brush wrapping. Each part has plastic bristles and long rubber fins. The main brush rolls effectively remove large and small debris and dirt and direct it to the suction port.
