OV51JCZ has region-labelled input specifications
Xiaomi’s Global specification gives EU/UK-standard input as 220–240 V AC, 50/60 Hz, and US-standard input as 100–130 V AC, 50/60 Hz. It lists a 20 V DC, 1.2 A dock output separately. Do not combine the regional inputs into a single universal range.
A region name in this specification is not proof of current retail availability or warranty coverage there. Check the actual supplied OV51JCZ label against your local supply before connection; if it differs or is missing, stop and ask Xiaomi support to identify the correct version.
For Xiaomi Robot Vacuum H40, Manufacturer model code: OV51. Base station model: OV51JCZ. Use each identifier under the label the manufacturer gives it. A sales SKU, technical model code and storefront record key do not necessarily identify the same level of configuration. Match the documented record to the unit or package you are checking, then verify accessories and regional support separately; a similar name or matching brand alone is not proof of interchangeability.
For Xiaomi Robot Vacuum H40, Manufacturer-listed regional dock input: EU/UK standard: 220–240 V AC, 50/60 Hz; US standard: 100–130 V AC, 50/60 Hz. Base station rated output: 20 V DC, 1.2 A. Robot rated power: 70 W. Robot rated voltage: 14.4 V DC. Robot charging voltage: 20 V DC. Match each electrical rating to the robot, dock or station component named in the source. Their input and output ratings are not interchangeable, and a cleaning or heating power figure is not the same as robot battery capacity. Keep the documented regional supply and exact accessory requirements when arranging charging; do not substitute an unlisted adapter or modify the electrical assembly.
Anti-tangle brushes have a carpet exception
Xiaomi describes the main brush as reducing hair entanglement, with results varying in use. That is not a promise of tangle-free operation. More importantly for a carpeted home, the anti-tangle side brush is explicitly not suitable for carpet cleaning; Xiaomi instructs users to fit the side brush specified for that use.
The reviewed information does not identify a replacement side-brush SKU. Ask for the H40-specific carpet-use brush rather than choosing one by appearance or the phrase “anti-tangle.”
Xiaomi Robot Vacuum H40 has the following documented official feature highlights: Up to 10,000 Pa suction when fully charged in Turbo mode in manufacturer testing; 5,200 mAh nominal battery capacity. The anti-tangle main brush reduces hair entanglement; results vary. The anti-tangle side brush is not suitable for carpet cleaning and must be changed to the side brush specified for that use. Treat the documented feature description as the manufacturer’s account of this configuration, keeping every stated mode, component and qualification together. It is useful for identifying what to check next; it is not an independent review score or a guarantee that a different bundle provides the same functions. Choose the feature relevant to your actual task and check its conditions before comparing a headline with another model.
For Xiaomi Robot Vacuum H40, use the suction entry with the manufacturer’s measurement conditions and cleaning configuration. A pressure maximum is not an independent measurement of debris pickup in your rooms. For a practical comparison, keep the documented brush, carpet and mopping behavior in view as well; the headline alone cannot rank two products or guarantee an outcome on every surface.
For Xiaomi Robot Vacuum H40, read mapping and obstacle recognition as distinct functions within the documented navigation system. A map describes the cleaning layout; an avoidance feature describes how the device responds to obstacles under its stated conditions. A mapping claim alone does not establish obstacle recognition, and neither claim guarantees coverage or recognition of every object. Use the model’s actual control and boundary instructions when preparing a room.
Automatic dust collection without assuming extra dock functions
The Global product description supports automatic dust collection and LDS multi-storey mapping. The dock measures 340 × 160 × 326 mm; the robot is 340 × 340 × 97 mm. Check space for both components. This record does not establish automatic mop washing or a fixed maintenance interval.
The nominal battery capacity is 5,200 mAh. The up-to-10,000 Pa claim is from a fully charged robot in Turbo mode during manufacturer testing; it is not a guarantee of carpet pickup or cleaning duration.
Xiaomi Robot Vacuum H40 has the following documented base station dimensions: 340 × 160 × 326 mm. Identify what the dock automates and what the cited temperature, capacity or interval actually measures. Washing water, drying air, an internal heater and temperature at the mop or floor are different locations. Likewise, a dust-collection estimate is not a maintenance-free period for the whole system. Keep the measurement point and use conditions attached to the feature when comparing station packages.
Xiaomi Robot Vacuum H40 has the following documented robot dimensions: 340 × 340 × 97 mm. Use the stated dimensions for the exact robot or station configuration. Preserve distinctions such as a raised sensor, retracted sensor or installed base when they are documented. A body outline does not include a guarantee that the robot can enter every opening or that the station fits with maintenance access; compare the relevant physical clearance separately.
Xiaomi Robot Vacuum H40 has the following documented nominal battery capacity: 5,200 mAh nominal. The same configuration lists manufacturer-listed regional dock input as EU/UK standard: 220–240 V AC, 50/60 Hz; US standard: 100–130 V AC, 50/60 Hz. Distinguish battery capacity from the runtime, charging or resume behavior specified for this model. A nominal capacity is not a guarantee of the same coverage in every cleaning mode. Keep the stated test and operating conditions when comparing products, and use the exact robot and dock instructions before arranging a charging routine or replacement.
Configuration and weight
For Xiaomi Robot Vacuum H40, Robot net weight: 3.64 kg. Keep this weight tied to the configuration and measurement scope given by the manufacturer. A figure excluding packaging or accessories should not be read as the weight of a delivered bundle. When planning placement or transport, identify which components are actually included rather than borrowing a value from a similarly named version.

FAQ
Xiaomi Robot Vacuum H40 frequently asked questions
Each answer stays within the facts and sources shown on this page.
01Is every H40 dock compatible with both EU/UK and US mains?
That is not established. The Global page gives separate EU/UK-standard 220–240 V AC and US-standard 100–130 V AC inputs, both at 50/60 Hz. Treat them as version-specific conditions and verify the supplied label, not as one universal input rating.
02Can I buy any anti-tangle side brush for H40 carpet cleaning?
No compatibility conclusion supports that choice. Xiaomi says the anti-tangle side brush is unsuitable for carpets and should be replaced with the brush specified for carpet use. The replacement SKU remains unconfirmed here; ask Xiaomi for the exact H40 part.
03What do H40’s 70 W and 14.4 V DC ratings describe?
They are the robot’s rated power and rated voltage, respectively. Its charging voltage is listed separately as 20 V DC. None of these electrical values is a body dimension or a substitute for the dock’s regional mains-input specification.
