Level with the Dreame L40 Ultra Gen 2

The Dreame L40 Ultra Gen 2 and the Roborock Qrevo Curv 2 Flow score the same, so either is a safe pick. The Dreame L40 Ultra Gen 2 goes first because it leaves owners a little happier. The Roborock Qrevo Curv 2 Flow does a little better with the review sites.

About the Roborock Qrevo Curv 2 Flow

The Qrevo Curv 2 Flow pairs a 20,000 Pa suction robot with a roller mop that is rinsed with fresh water as it cleans. The mop presses down with up to 15 N of force. A scraper inside the robot wipes the roller and sends dirty water to a wastewater tank. The roller can extend past the body to reach closer to walls. When the robot detects carpet, the roller lifts up to 15 mm, and a guard underneath blocks water.

Navigation is PreciSense LiDAR with real-time mapping. The robot recognizes up to four floor levels and supports no-go zones. It identifies objects at least 5 cm wide and 3 cm tall. For pickup it uses a DuoDivide main brush and anti-tangle side brushes. The side brushes do not extend, and Gizmodo found about an inch and a half left unswept in corners.

The dock empties the robot into a disposable dust bag, washes the roller with water heated to 167°F and dries it with air up to 131°F. Android Authority reports about 4 L for the clean-water tank and just over 3 L for the wastewater tank, and says the drying cycle runs three hours even in eco mode. Detergent goes into the fresh water tank by hand, since there is no separate detergent tank. The box holds the robot, dock with a pre-installed dust bag, power cord and manual. At 4.7 inches tall, the robot cannot get under very low cabinets.

What owners report about the Roborock Qrevo Curv 2 Flow

We found little owner feedback on this exact model that we could open, so we do not report an owner pattern here. The points above on edges, corners, drying time and upkeep come from published reviews, not from owners.

Who the Roborock Qrevo Curv 2 Flow suits

It fits a home with mostly hard floors and a few rugs, especially with pets. The anti-tangle brushes handle hair, the mop lifts over carpet, and the dock does the washing and drying. It also suits anyone who wants LiDAR maps for several floors.

Look elsewhere if you need tight corners or wall edges cleaned reliably, or if your furniture sits low. The side brushes do not extend, and there is no mop-only mode. Dried-on stains can need a second pass. The dock is large, and the long drying cycle is audible. The Dreame L40 Ultra Gen 2 has an extendable side brush and mop for corners. The eufy Omni E25 has an extending arm for edges.

Questions about the Roborock Qrevo Curv 2 Flow

What is the difference between the Roborock Qrevo Curv and the Qrevo Curv 2 Flow?

The Curv 2 Flow swaps the original's round pads for a roller mop with about 15 N of pressure, against roughly 6 N. Suction rises from 18,500 Pa to 20,000 Pa, per Gizmodo. It also drops the mop-only mode, and its side brushes do not extend.

How tall is the Roborock Qrevo Curv 2 Flow?

The robot is 4.7 inches tall and 13.9 inches wide and deep. Gizmodo found that height kept it from reaching under some low cabinets.

Does the Roborock Qrevo Curv 2 Flow mop carpet?

No. The roller mop lifts up to 15 mm when it detects carpet, and a guard under the robot blocks water. Gizmodo found its rug detection was not always accurate.

Does the Roborock Qrevo Curv 2 Flow need cleaning solution?

Detergent is optional. If you use it, you add it by hand to the fresh water tank, because there is no separate detergent tank. Android Authority's reviewer used Roborock's floor cleaning solution, one capful per tank.

How long does the Roborock Qrevo Curv 2 Flow take to charge?

About 3 hours from 15% to full, with a 5,200 mAh battery, per Roborock. Gizmodo found a vacuum-then-mop run in a 650 square foot apartment barely finished on one charge.

How we score it

Every score here comes from our ranking model; no editor sets the order. Most of each score is what the review sites say: the scores their own reviews give each model, and whether their best-of lists name it. For this guide we read CNET, Homes & Gardens, TechRadar, The Verge, Tom's Guide and Wired. The rest is how happy owners are, held back where few owners have rated a product, and how new it is. Value for money earns its own badge rather than a higher place. We compared 17 models for this guide before settling on these ten.

Brands can't pay to be included or to move up. We last checked these picks in October 2026.
