The washer and dryer Z1 Ultra and M1S Ultra were announced by Roborock in China on February 25, 2026, according to Gizmochina. The models combine Super Hydrolysis, FineFoam 2.0 foam, 99.99% sterilization, low-temperature drying, automatic detergent, and control via the Roborock app in smart cycles.
The washer and dryer became the new target of Roborock in China with the launch of the combined models Z1 Ultra and M1S Ultra. Known primarily for robotic vacuums, the brand announced two machines aimed at washing, drying, and sanitizing clothes with proprietary technologies.
According to Gizmochina, the devices were announced on February 25, 2026, and went on pre-sale on JD.com. The Z1 Ultra appears as the main model, while the M1S Ultra emerges as a compact option for small quantities of clothes and smaller families.
Roborock bets on smart laundry in China
Roborock presented the two models as part of a more automated laundry proposal. The central idea is to combine washing, drying, sterilization, odor removal, and app control in integrated devices.

Space technology used to search for water on Mars is now hunting for invisible leaks under the streets of São Paulo, using satellites, AI, and chlorine signals to help Sabesp recover up to 6.7 billion liters of water.
The washer and dryer Z1 Ultra was announced for 6,299 yuan, about US$ 916 according to the conversion provided by the source. Meanwhile, the M1S Ultra is priced at 3,299 yuan, about US$ 480, positioned as a smaller and more affordable version within the line.
Super Hydrolysis uses electrolyzed water and microbubbles
The main technical highlight of the two models is the proprietary technology called Super Hydrolysis. According to the source, it breaks water molecules into ions and microbubbles through electrolyzed water and atomization.
The proposal is to help in the removal of stains and the sterilization of fabrics without leaving chemical residues. In practice, Roborock tries to transform water, bubbles, and electrolysis into a central argument against dirt, odors, and microorganisms in clothes.
Z1 Ultra targets families with a higher volume of laundry
The Roborock Z1 Ultra has the capacity to wash 12 kg and dry 7 kg. These numbers position the model as the main option in the line, aimed at those who need to handle more items daily.
The washer and dryer also features automatic detergent dosing and compatibility with the Roborock app. Thus, the user can control smart functions via mobile, although the source does not detail all the features available in the app.
FineFoam 2.0 foam promises to penetrate fabrics
The Z1 Ultra uses FineFoam 2.0 technology, which pre-mixes detergent, water, and air to create a dense foam. According to Roborock, this foam penetrates more deeply into fabrics during washing.
The company claims that the model achieves a washing performance index of 1.34 and removes common stains like blood, grease, and paint. The point to note is that these data come from the manufacturer itself, so they should be read as specifications released at launch.
99.99% sterilization appears as a strong appeal
Another highlight of the Z1 Ultra is the sterilization system that works at all water temperatures. The source reports an efficiency of 99.99%, with dual UV-assisted sterilization and antibacterial coating in the drum.
The model also includes high-temperature self-cleaning at 95 °C, as well as a quick 15-minute self-cleaning option. For those concerned with intimate garments, bedding, or fabrics used in intense routines, this is one of the most striking points of the technical sheet.
Low-temperature drying targets delicate fabrics
A Z1 Ultra uses a molecular sieve system Zeo-cycle for gentle drying at low temperature. According to the source, the proposal is to better care for delicate fabrics, such as wool, silk, and linen.
The washing and drying machine also received SteamEase 2.0 technology, which promises to reduce wrinkles and eliminate bacteria, mites, and odors in a 20-minute cycle. This feature aims to bring the machine closer to a more practical routine for clothes that require extra care.
M1S Ultra is a compact version for small loads
The Roborock M1S Ultra was introduced as a compact alternative. The model has a capacity to wash 1.2 kg and dry 0.5 kg, being suitable for smaller families or small amounts of clothes.
Despite its reduced size, the M1S Ultra also features Super Hydrolysis technology for stain removal and sterilization. The source further informs that the device integrates FineFoam 2.0 and a real-time drum cleaning system during cycles.
Compact model has 32 washing and drying programs
The M1S Ultra offers 32 washing and drying programs, including options for underwear and delicate fabrics. This detail reinforces the proposal of specific use, more focused on smaller, frequent pieces or those requiring separate sanitization.
Roborock claims that the OxiPure Super Hydrolysis technology removes bacteria, mites, and viruses with 99.99% efficiency. As with any product launch, this data represents a claim by the manufacturer presented in the technical disclosure.
Pre-sale opened on JD.com
According to Gizmochina, both models were already available for pre-sale on JD.com after the announcement in China. The source does not inform about a launch in Brazil or a forecast for arrival in other markets.
This is important because the topic deals with a product announced in the Chinese market. Therefore, price, availability, and features should be understood within this context, without asserting national sales or arrival in Brazilian retail.
Roborock expands its reach beyond robotic vacuums
Roborock is best known to the public for its robot vacuums, but the launch shows the brand’s advancement in other areas of the smart home. The source itself mentions, in a related news article, the P20 Max robot vacuum, with 35,000 Pa suction and obstacle avoidance with artificial intelligence.
With the new washing and drying machine, the company is also trying to occupy the home laundry space. The move follows a larger industry trend: connected appliances, automatic cycles, and sanitization functions being used as competitive differentiators.
When the laundry room becomes a technology competition at home
The Z1 Ultra and the M1S Ultra show how the laundry room has ceased to be just a simple household chore and has become a showcase for technology. Super Hydrolysis, microbubbles, sterilization, delicate drying, and an app appear as arguments to reduce effort and expand control.
The question is whether these features really change the routine or if they are still more attractive on paper than in daily use.
Would you pay more for a washing and drying machine with microbubbles, 99.99% sterilization, and app control, or do you prefer a more traditional, simpler machine? Leave your opinion in the comments.
