Ecovacs Deebot T8 AIVI · Roborock Qrevo 2 Pro

On-robot camera means cloud dependency: Ecovacs uploads video frames to their servers for AIVI processing. Privacy controls exist, but no local-processing alternative; offline operation falls back to LiDAR alone and loses obstacle avoidance.

AIVI false positives extend cleaning time: Camera misidentifies reflections and shadows as obstacles, causing pauses and delayed exits. Firmware updates reduced frequency but did not eliminate it.

One pass for two jobs, at the cost of tending it: the 240 mL reservoir and mop plate let the machine vacuum and mop together, but the water is finite on larger floors, the pad is washed and dried by hand, and carpet detection means a mop run has to route around any rug in the way.

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.

Privacy-first buyers uncomfortable with on-robot cameras

AIVI requires cloud upload for processing; local-only alternatives (pure LiDAR) are more privacy-friendly despite app limitations.

Homes with poor Wi-Fi coverage

Cloud AIVI processing depends on stable connectivity. Unreliable Wi-Fi results in AIVI timeouts and falls back to LiDAR-only mode.

Low-light or reflective-surface homes

AIVI false positives documented in low-light and in rooms with mirrors or glass. Firmware cannot fully eliminate phantom obstacle stops.

Buyers expecting a dock that services the mop

Mopping on this generation is hand-tended: fit the reservoir and pad before a mop run, refill during large jobs, then remove, rinse and dry the pad afterward. The optional station empties dust only. Later machines with washing docks moved that work off the owner.

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.
