Roborock Qrevo 2 Pro · Trifo Lucy

The dock washes and dries mop pads at temperatures usually reserved for pricier docks, but structured-light sensors cannot see a charging cable the way a camera-equipped flagship can.

Auto Mop Removal parks the mop before carpet; carpet-border misreads however still let the robot begin mopping onto an area rug until a no-mop zone is drawn.

2.4GHz-only Wi-Fi: a home running a merged or 5GHz-first network may need to split bands before the robot will connect.

Camera vSLAM without LiDAR recognizes what an object actually is and routes around it, but it depends on a clean lens and a mapped room, where a laser measures geometry regardless.

A 600 ml bin is large for a robot this size and holds a week of debris, but there is no self-emptying base, so clearing it is always a manual step.

Floors with loose cables, cords, or ribbons

Independent testing found the robot picks up nearly every unflattened cable it crosses; its structured-light sensors cannot distinguish thin cords from open floor the way a camera can.

Networks that only offer 5GHz Wi-Fi

The robot connects on 2.4GHz exclusively; a router broadcasting only a 5GHz band, or one merged without a 2.4GHz option, will not complete setup.

Large homes above roughly 3,000 sq ft

No independent test of coverage above 3,000 sq ft was found; the 253-minute rated runtime is unconfirmed against a layout this size in a single session.

Deep or high-pile carpet needing verified deep-clean suction

20,000 Pa is a mid-tier suction figure and no independent test of thick, high-pile carpet performance has been published for this specific model.

Homes with area rugs needing hands-off no-mop zoning

A documented review found the robot began wetting a dining room rug before its boundary was manually outlined; carpet-edge detection is not fully automatic on rugs.

Owners with large homes over 3000 sq ft

Runtime is 120 minutes on the 5,200 mAh pack, against Trifo's claimed coverage of up to 2,700 sq ft. Beyond that, coverage stretches across several scheduled runs.

High-pile or shag carpet users

Owner reports document suction loss and motor strain on deep pile. The brush is designed for hard floors and medium carpet.

Owners preferring hands-off dock interaction

There is no self-emptying dock. The 600 ml bin is large for the category and typically needs emptying once or twice a week, but it is still a manual step, as is rinsing the mop pad after a wet run.

Users without reliable WiFi 2.4GHz connectivity

Lucy does not support 5GHz band; homes with only 5GHz networks require separate 2.4GHz access point. Offline cleaning operates but skips app notifications.

Buyers who do not want a networked camera in the house

The camera that navigates also serves as a home monitor. It streams live 1080p video with infrared night vision to the app, captures motion-triggered clips and can be viewed remotely, and that imagery is handled through the Trifo Cloud. Anyone who wants a vacuum without a connected camera should look at a LiDAR-based machine.
