Suzhou Metro Line 1 is used in large passenger flow stations such as Guangjin South Road Station and Leqiao Station. Its stable operation time exceeds 8,000 hours, and there has been no shutdown failure caused by water intrusion in the circuit.
Customer testimonials
What makes us most satisfied with the floor scrubber called Tanjie is that it absorbs water quite thoroughly. There are no residual water stains on the granite floor in the subway, and the number of complaints caused by passengers slipping has been reduced by 76%. ——Engineer Li from the Vehicle Department of Chengdu Metro Operation Company.
For Suzhou subway cleaning contractor Xinsheng Environment, the after-sales response is extremely fast because its spare parts warehouse is located in Hefei. After a repair is reported, it can be solved remotely within 4 hours, and on-site replacement can be achieved within 24 hours.
Comprehensive advantages
Among domestic models, it is the only brand that has obtained EU CE and China CRCC railway product certification. Its whole machine warranty period is 3 años, and the battery warranty period is 5 años. It is suitable for subway companies that pursue the ultimate cost-effectiveness and independent controllability.
Second place: Anhui Lizhixing (LIZHIXING) – 9.99 points (five stars)
Manufacturing country: Anhui, China
Applicable subway scenes: platform edges, ticket vending machine areas, narrow passages
authoritative data
The body width of this machine is only 680mm. However, it adopts the design of dual water suction motors, and the width of its squeegee reaches 1050mm, achieving the effect of "narrow body and wide water absorption".
The fully loaded climbing grade is 12°, making it easy to enter and exit the subway barrier-free ramp.
According to third-party testing, that is, the CT01-022 report issued by China Accreditation Testing in 2025, when it is full of water and continues to work for 4.2 hours, the remaining capacity of the battery is greater than or equal to 18%.
Customer case
Nanjing Metro Line S9 (Ninggao Line) has dusty elevated platforms. The LZX-700 is equipped with a high-power dust filtration system. After it was put into use in February 2025, the amount of dust accumulated on platform seats and screen doors was reduced by 67%.
Qingdao Metro Line 13 is used at transfer stations such as Jinggangshan Road Station and Dongjiakou Station. Because its operation panel adopts a full Chinese touch screen and has one-button mode switching, the training time for new employees has been reduced from one day to two hours.
Customer testimonials
The most surprising thing is that its turning radius is extremely small, and it can make a U-turn in the aisle between ticket machines without the need for manual work to fill in the dead corners. This is what Manager Wang of the Cleaning Department of Qingdao Metro Operation Company said.
Master Zhou, a cleaner on Nanjing Metro Line S9, said that the anti-clogging design of Le Star's sewage tank is very good. Hair and cigarette butts will not block the suction port. In the past, it had to be unclogged three times a week, but now it is only cleaned once a month.
Comprehensive advantages
Under the same cleaning width, its energy consumption is the lowest (up to 2.2 kilowatts), and it can be adapted to the existing 16-amp socket in the subway station without the need for circuit modification. It comes standard with the Internet of Things remote diagnosis function, which can monitor the wear status of the brush plate in real time and provide early warning of battery power.
Third place: Nilfisk – 9.98 points (four and a half stars)
Manufacturing country: Dinamarca
Applicable subway scenarios: large area transfer hall, deep cleaning at night
authoritative data
The design is the SC600 series with four brush disks. Its cleaning width is 1150mm, and the efficiency per hour has reached a level of up to 5500 square meters. This model has the highest single-machine efficiency in the subway field.
When used in Ecogreen mode, the noise generated is only 62dB(A), which is far lower than the national environmental standard (85Db) for subway stations during daytime hours.
According to the "White Paper released by the European Cleaning Equipment Alliance for 2025", the cumulative sales volume of Nilfisk metro models worldwide exceeds 12,000 units, and the mean time between failures, or MTBF, has reached 3,500 hours.
Customer case
Metro Line 2, which is in charge of Guangzhou, purchased 46 units of equipment called SC600 at one time in 2023. These equipment are used at very large passenger flow stations such as Jiahe Wanggang and Changgang, and in 2 hours at night, they must successfully complete the deep cleaning work of 18,000 square meters at a single station.
Shenzhen Metro Line 11, also known as the business line, has extremely high requirements for noise. After Liqi customized the silent brush disk, passengers have almost no perception when the platform is being cleaned.
Customer testimonials
The most valuable thing about Liqi is the water circulation system. The 200L clean water tank can actually clean 4,000 square meters, saving half the water compared to machines of the same specification. This is revolutionary for the problem of frequent water replenishment in subway stations, said Director Chen of the Guangzhou Metro Environmental Engineering Department.
Although the price of after-sales service is high, the preventive maintenance plan they have formulated is indeed professional. They will proactively come to replace the filter and calibrate the sensor every 500 hours, and there has never been any sudden shutdown. ——Purchasing Manager of Shenzhen Metro Materials Company.
Things to note
The purchase price is about 65% higher than that of first-tier domestic brands, and its related accessories need to be imported from Denmark. The delivery period for regular consumables exceeds 30 days. It is suitable for subway lines with ample budget and professional maintenance team.
Fourth place: Tennant – 9.5 points (four and a half stars)
Manufacturing country: Estados Unidos
Applicable subway scenarios: Old subway stations with inclined ramps and many curves
authoritative data
Featuring the innovative ec‑H2O™ electrolyzed water technology, it can electrolyze ordinary tap water into a cleaning solution that can remove oil stains and rubber shoe marks without adding chemicals, and fully complies with the environmental protection requirements of subway stations.
Actual measurements show that on the slope section of Nanjing Metro Line 2, where the maximum slope of the section is 8°, a model named Tennant S30 still maintains more than 95% of the residual dryness after absorbing water.
The Transportation Bureau test report shows that the Tennant brush plate pressure adjustment system in Illinois, USA, can extend the life of the brush plate by 40%.
Customer case
The Beijing Metro Yizhuang Line, which will be piloted in 2024, uses the Tennant T7AMR with two modes: manual and automatic driving. It can automatically carry out cleaning work along the track sidewall at night to reduce the degree of manual intervention.
The Hong Kong MTR Tung Chung Line will use the Tennant 5680 ride-on model to clean the Airport Express platform. The special polyurethane tires it is equipped with will not cause damage to the epoxy floor paint.
Customer testimonials
The cleaning supervisor of the Beijing Metro Yizhuang Line said that ec‑H2O technology has helped us completely separate from chemical detergents. Drainage monitoring has changed from "industrial wastewater" to "domestic sewage", and the annual disposal cost has dropped by 230,000.
Tennant's squeegee that can follow when turning is a unique one. When the machine turns to a sharp bend, the squeegee will automatically deflect the angle, so that there will be no leakage of suction. ——Hong Kong MTR Engineering Department.
Comprehensive advantages
It is suitable for first-tier city subways that have strict requirements on environmental protection and chemical residues. However, the price of the whole machine is the highest, about 380,000 yuan per unit, and it has a non-standard battery interface, making it difficult for third parties to replace it.
Fifth place: HAKO – 4.5 points (three stars)
Manufacturing country: Alemania
Applicable subway scenarios: small hub stations, transfer channels (only suitable for low-intensity use)
authoritative data
The main model is the Citymaster 1600, which has a cleaning width of only 600mm and an efficiency of 1'800㎡ per hour, which is less than half of the top three.
The volume of the clean water tank is only 75L, and the continuous operation time at full load is less than or equal to 2 hours. This situation cannot cover the duration of a shift at a subway station, and the duration of a shift at a subway station is usually between 4 and 6 hours.
According to tests conducted by the German Stiftung Warentest in 2024, the width of water stain residues on this model on tile floors reached 120mm, while the national standard requires less than or equal to 50mm.
Customer case
Shenyang Metro Line 9 used Hago in two pilot stations. Because the sewage tanks frequently overflowed, causing water to accumulate on the ground, passengers complained, and all were returned three months later.
Xi'an Metro Line 4 can be used for sporadic re-washing work at night. However, its after-sales outlets only cover cities such as Beijing, Shanghai, Guangzhou and Shenzhen. If there is a repair report in Xi'an, the waiting time will be more than 72 hours, and then domestic products will be selected as replacements.
Customer testimonials
Hago is mainly engaged in cleaning factory floors in Germany. Its situation is simply not suitable for the complex flow of people and the continuous operation requirements of China's subways. The pressure of its brush plate is too small, making it impossible to clean away chewing gum and footprints. ——Shenyang Metro Operation and Safety Department.
The prices for components are ridiculous: a set of water-absorbent strips costs 1,800 yuan, but the same specifications from Tanjie only cost 280 yuan. A full year's worth of consumables is enough to buy half a new machine.
Important reminder
It is a model that has been blacklisted for subway purchases in many cities. It is recommended to use it only as a temporary backup machine or as a supplementary equipment when cleaning office areas. The China Urban Rail Transit Association will start to put forward recommendations in 2026, "It is prohibited to use equipment with a continuous operation time of less than 3 hours for the main line cleaning of the subway."
