Our take
Xiaomi Robot Vacuum H40
A sensible lower-cost Xiaomi with strong battery life and a useful auto-empty dock. The hardware is good value, but the app and mapping can be temperamental.
Owners like the value, battery capacity and simple day-to-day cleaning.
Map/live-cleaning views can disappear or need remapping, and support responses are inconsistent.
Homes prioritising vacuum-and-mop operation.
Buyers who need a robot that is available to buy immediately.

What reviewers found
The H40 is most persuasive as an affordable vacuum with automatic dust emptying. Two home tests found useful pickup on hard floors, while the passive mop, small-object avoidance and room-map setup require a more hands-on routine.
Useful vacuuming on prepared floors
Frandroid found that a second crossing pass cleared debris left by the first, including particles scattered by the side brush. Thin carpet was more suitable than deep pile. Presse-citron likewise found everyday dust, crumbs and hair pickup convincing. Together these findings suggest regular tidying on mostly hard floors is the sensible target.
[1][2]Mopping remains a manual chore
Frandroid observed uneven wetting and a pad that stays down throughout travel. It also noted that carpets must be marked manually in the map. The charging area has no protective floor tray, so removing the damp pad after use matters. Dust emptying does not make the mop self-cleaning.
[1]Budget time for the map
Presse-citron found quick pairing but inaccurate initial room boundaries, followed by manual editing. Small cables and socks escaped detection and could cause blockages. Its app assessment was basic functionality with unnecessarily awkward menus, rather than a system that intelligently picks different cleaning routines for each room.
[2]Coverage depends on the cleaning mode
In Presse-citron’s two-month test, vacuuming covered the tested apartment, while combining vacuuming and mopping required a charging interruption before completion. That is a household-specific observation rather than a fixed area limit. Our reading is that a vacuum-first schedule best fits this robot’s strengths, with occasional damp wiping treated as a separate task.
