It wins on 25000Pa against 18500Pa, 231 minutes against 180, a 3-year warranty against 1 year, and a 3.2 L dock bin against 2.7 L. The Roborock Qrevo Edge S5A still wins where it counts for some buyers: it is the quieter of the two on its rated 52 dB, and its Home Assistant support works today, where the Dreame lists Home Assistant as an upcoming OTA update. Both mop, wash, dry and self-empty from an automated dock, and both use LiDAR mapping with obstacle detection and no-go zones. Buy the Dreame L40 Ultra Gen 2 for suction, runtime and warranty, and the Roborock Qrevo Edge S5A if you want Home Assistant now and the quieter chassis.

What the differences mean

Suction

The Dreame L40 Ultra Gen 2 is rated at 25000Pa against 18500Pa on the Roborock Qrevo Edge S5A, which is the difference you would feel on thick carpet and embedded hair rather than on bare floor.

Warranty

The Dreame L40 Ultra Gen 2 carries 3 years against 1 on the Roborock Qrevo Edge S5A, a notable edge on a robot with a self-cleaning dock.

Runtime

At 231 minutes against 180, the Dreame L40 Ultra Gen 2 finishes a larger floor before it needs to recharge, helped by its multi-floor mapping across up to four levels.

Noise

The Roborock Qrevo Edge S5A is rated at 52 dB, quiet enough that owners run it at night or during calls.

Home Assistant timing

The Roborock Qrevo Edge S5A works with Home Assistant today. The Dreame L40 Ultra Gen 2 lists Home Assistant, Matter and Apple Home as arriving through an upcoming OTA update, so it works with Alexa and Google Home now.

Dock bin

The Dreame L40 Ultra Gen 2 empties into a 3.2 L dock bin against 2.7 L on the Roborock Qrevo Edge S5A, so it can go a little longer between bag changes.

Which one to buy if

What owners say

Both groups bought in for the same reason, a dock that empties, washes and dries so floors are mostly hands-off, and both come away happy with pet-hair pickup and mapping. Dreame L40 Ultra Gen 2 owners single out the extendable side brush reaching corners and the strong suction, and their standard complaints are hair tangling in the wheels or main brush hard enough to throw off mapping, mop pads that occasionally detach mid-run and an app with a real learning curve. Roborock Qrevo Edge S5A owners emphasise how quietly it runs, enough for night cleaning, and the anti-tangle brush keeping long hair off the roller; they mention missing very tight carpet edges, cords that still snag and a footprint that will not fit under some low furniture.
