The Tinymu Smart Toilet Cover Pro-H was a replacement bidet toilet seat crowdfunded on Xiaomi Youpin in China in May 2021—not a new Xiaomi product launch in 2026. It added bidet washing, warm-air drying, a heated seat, deodorization, bowl pre-wetting and electrolyzed-water functions without requiring a complete smart toilet replacement.
Launch reports listed crowdfunding prices of 999 yuan for the cover alone, excluding filters and installation, or 1,299 yuan for a package with two filter elements and installation. Planned shipping was reported for June 2021.

What the Tinymu Pro-H actually was
The Pro-H was a smart toilet seat and cover designed to replace an existing toilet seat. It was not a complete smart toilet or a self-cleaning bathroom fixture. Its functions were built around washing, drying, heating, odor reduction and convenience controls.

Gizmochina’s launch report and corroborating coverage from iGeekphone place the campaign in May 2021. Reports were published on different days, so May 2021 is the clearest description of the launch period.
The eight advertised cleaning modes
English-language reports used slightly different translations for the mode names. The following labels describe the advertised functions rather than necessarily being the official English names:
| Reported mode | Intended use |
|---|---|
| Menstrual care | A washing setting described for use during menstruation. |
| Spa | A comfort-oriented washing program. |
| Children’s cleaning | A one-button children’s function reportedly usable without the child sitting normally on the seat. |
| Women’s cleaning | A front-washing setting. |
| Buttocks cleaning | A rear-washing setting. |
| Massage cleaning | A pulsating or varied washing pattern. |
| Reciprocating cleaning | A mode in which the spray position moves back and forth. |
| Selected-area cleaning | A user-directed or targeted washing program. |
The descriptions should not be treated as independently tested differences in water pressure, nozzle travel or spray temperature. The available launch coverage primarily lists the modes and gives only limited technical detail. The children’s feature was a product-description claim, not evidence of independently verified child safety; children should be supervised.
Electrolyzed water and the hygiene claims
The Pro-H was reported to electrolyze household tap water, producing water containing hypochlorous acid. Launch coverage attributed to the system a sterilization efficiency of more than 99% against Escherichia coli and Staphylococcus aureus. It also said the treated water could return to ordinary water after a period of time.

- LED Night Light: Move through your bathroom with ease at night. Simply turn on the built-in LED night light to cast a gentle glow, providing ample illumination without being disruptive
That claim needs narrow interpretation. The reports do not provide a laboratory, test standard, hypochlorous-acid concentration, contact time, sample size or independent verification. A claim about two named organisms does not establish sterilization of the whole toilet or bathroom, and it is not evidence that the product prevents disease transmission. The feature should not replace routine toilet cleaning or appropriate disinfection.
Pre-wetting is not self-cleaning
When the lid was opened, the cover reportedly sprayed a multidirectional mist inside the bowl. This pre-wetting was intended to reduce waste adhesion and make flushing easier.
It is best understood as bowl-coating assistance. It does not mean that the bowl, seat, nozzle or surrounding bathroom can be left without regular cleaning.

Warm-air drying
Reports listed four warm-air settings:
- Room temperature
- 40°C
- 45°C
- 50°C
No drying-time or drying-effectiveness test was provided, so warm-air drying should not be treated as a guarantee of completely hands-free drying.

Heated seat
The seat was described as having four heating levels. The exact temperatures for those levels were not verified in the available reports.
Odor reduction
The deodorization system was described as combining activated carbon, a catalytic deodorizing material and a fan. It reportedly activated when someone sat down, with manual operation also mentioned in translated coverage.
There is no verified airflow rating, noise measurement, odor-removal rate or filter-replacement interval. The deodorizer should therefore be treated as a convenience feature, not maintenance-free odor control.
Controls and smart-home uncertainty
The product had side controls and remote operation. A Wired Italia report also mentioned a remote, smartphone app and XiaoAI control.

However, other coverage described the Pro-H as a trimmed version of an earlier AI model. The available sources do not establish the exact app, language, account-region, firmware or XiaoAI support for every Pro-H unit. Imported examples could have China-region software or limited cloud support.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Compatibility and installation
The campaign coverage claimed compatibility with approximately 95% of mainstream toilets and described adaptability to curved, wall-mounted and small toilets. That percentage was a manufacturer-reported estimate, not a substitute for checking a specific bathroom.
Before installing any replacement bidet seat, verify:
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
- Toilet bowl length and width
- Mounting-hole spacing and anchor design
- Hinge and seat clearance
- Space between the bowl, tank or wall and the side controls
- Water-supply connection and required adapters
- Whether the nozzle aligns correctly with the bowl
- Access to a suitable grounded electrical outlet
- Local voltage, plug type and electrical certification
- Availability of replacement filters and installation parts
The 999-yuan price excluded installation, and the reports do not document the Pro-H’s exact voltage, power draw, plumbing adapter or electrical certification. A unit designed for China should not be assumed to work safely with North American plumbing or electrical systems.

Historical price and package details
| Package | Reported 2021 price | Included or excluded items |
|---|---|---|
| Cover only | 999 yuan | Filters and installation excluded. |
| Installation package | 1,299 yuan | Reported to include two filter elements and installation. |
These were historical Xiaomi Youpin crowdfunding prices, not current retail prices. Crowdfunding pricing also does not guarantee continuing parts, warranty or software support.
Availability in 2026
The available reporting verifies a China-based Xiaomi Youpin campaign in May 2021 and planned June 2021 shipping. It does not establish that the Tinymu Pro-H is still sold, officially supported, or available through an official U.S. purchasing channel in 2026.
A third-party listing would not by itself confirm warranty coverage, safe voltage, local certification, compatible plumbing parts, replacement filters or app support. International buyers should treat those as unresolved checks rather than assume the product is a supported import.

During its campaign, the Pro-H could have appealed to China-based buyers who wanted bidet washing, heating and drying without replacing an entire toilet. Its multiple programs, pre-wetting and electrolyzed-water system gave it a feature-rich specification for a replacement seat.
It is a weaker choice for anyone who needs a currently supported product, a local warranty, guaranteed replacement consumables, verified compatibility with a specific toilet or confirmed compliance with local electrical requirements. Buyers interested in the category today should generally compare currently supported bidet seats from established bathroom-fixture suppliers rather than rely on an old crowdfunding import.
Bottom line
The Tinymu Smart Toilet Cover Pro-H was an ambitious 2021 Xiaomi Youpin crowdfunding product with eight advertised washing modes, heated seating, warm-air drying, pre-wetting and deodorization. Its historical price was 999 yuan without filters and installation, or 1,299 yuan with two filters and installation. In 2026, however, availability, parts, software, voltage, certification and warranty matter more than the headline feature count.
