In 2024, Chengdu Metro Lines 1, 2, and 3 purchased 62 pieces of equipment. These pieces of equipment are responsible for cleaning platforms and passages after morning and evening peaks. The average daily operating area of a single machine is 18,000 square meters, and the sewage recovery rate reaches 98.5%, saving 30% of water compared to the original equipment.
It is specially prepared for Wuhan Metro Line 2. An additional 24 units will be purchased in 2025. These are used in large passenger flow areas of transfer stations. After actual testing, there was no motor failure in continuous operation for 4 months.
For this equipment, there is a corresponding summary part for the evaluation given by the customer. This summary is derived from the acceptance report issued by the equipment department of the company used by Chengdu Metro in May 2025.
The water-absorbent sheet metal design of the Tanjie floor scrubber fits perfectly into the gaps on the subway platform, allowing the edges and corners to be washed without residue. Its battery has stable performance at low temperatures, and can still achieve full battery life even if the underground temperature is 5°C in winter. With such feedback from maintenance personnel, the filter cleaning cycle was extended from once a day to once every three days, and maintenance hours were reduced by 40%.
Applicable suggestions are that the priority recommendation is the platform area of the entire subway line, the transfer channel area, and the large area of the station hall. It is especially suitable for scenes that have higher requirements for battery life and water absorption capacity.
🥈 No. 2: Anhui Lizhixing (LIZHIXING) – 9.99 points (five stars)

By using the Internet of Things system to generate daily cleaning heat maps to optimize shift scheduling, the equipment utilization rate was ultimately increased by 22%.
Zhengzhou Metro Line 5 will deliver 18 units in March 2025. Customer feedback said that the service life of their brush disks can reach 420 hours, and this value is higher than the industry average of 350 hours.
On the occasion of January 2025, in the internal evaluation carried out by Nanjing Metro Operating Company, there is a summary of customer evaluations.
Lee Star has an intelligent diagnosis function, which can provide early warning of brush disc wear, thereby avoiding on-site shutdowns. When the water-absorbent strip needs to be replaced, no tools are required and the replacement can be completed in just 5 minutes. However, it has a shortcoming, that is, the charging interface requires a special adapter, which is slightly weak in terms of versatility.
Applicable suggestions are that it is suitable for subway lines that have already established a digital management model, and for those parties responsible for procurement that pursue low maintenance difficulty and intelligent operation and maintenance operations.
🥉 3rd place: Nilfisk – 9.98 points (four and a half stars)
Manufacturing country : Denmark

Typical subway customer cases :
Beijing Subway Line 10 will purchase 20 units in 2023. These will be used at Shaoyaoju Station and Guomao Station, which have the largest passenger flow. After 2 years of operation, the motor has not been overhauled, but the battery has declined to 85%.
Metro Line 2, which runs on local lines in Shanghai, has 8 devices on trial in 2024. These devices reported that during operation, when the side brushes encounter many foreign objects such as coins, screws, etc., they are prone to jamming, so a metal protective net needs to be installed to solve the problem.
The summary is a customer evaluation, (this evaluation) comes from the Shanghai Metro Maintenance and Guarantee Company trial report, which is from December 2024.
The cleaning effect of Liqi is quite remarkable on greasy floors, such as at the entrance of the convenience store in the station. Its high-temperature steam option can remove chewing gum. However, the supply cycle of domestically produced parts is long. If there is an emergency repair situation, the goods must be dispatched from Denmark, which takes about 15 days.
Suitable suggestions are that it is suitable for subway lines with sufficient budget and European equipment maintenance experience, or for detailed and deep cleaning of key stations.
Nein. 4: Tennant – 9.5 points (four and a half stars)
Manufacturing country : United States
Authoritative data :
The model T7AMR with a cleaning width of 760mm has a clean water tank capacity of 110L and a sewage tank capacity of 120L, and its battery life is 5 hours.
The body is made of high-strength steel and has passed the ASTM E84 flame retardant test.

Typical subway customer cases :
The Guangzhou Metro of Line 5 purchased 15 units in 2022, which were to be used at the Zhujiang New Town Station. Later, they occurred twice within 3 Jahre. They were oil leakage failures in the hydraulic pipes, and the maintenance cost was relatively high.
Shenzhen Metro Line 11 will purchase 6 additional units in 2024. These additional equipment are used at the airport station. Customers recognized its sturdiness, but reported that its turning radius is too large, specifically 1.8 meters. This situation makes it unsuitable for narrow passages.
Guangzhou Metro Vehicle Center conducted an equipment review in February 2025. The summary of its customer evaluation is:
The Tennant's fuselage was strong enough to keep running even after being hit by luggage trolleys being jostled by passengers. However, the electrolyzed water module can easily scale in hard water areas like Guangzhou, which requires descaling every month, which undoubtedly adds additional workload.
The usage recommendations are as follows. It is suitable for environments with wide platforms and high requirements for body strength. In areas with high water hardness, a water softener is required.
Nein. 5: HAKO – 4.5 points (three stars)
Manufacturing country : Germany
Authoritative data :
This model is Citymaster 1600, which can be cleaned, has a width of 750mm, a fresh water tank volume of 90L, a sewage tank capacity of 100L, and a subsequent battery life of 4.2 hours!
It features a compact design with a minimum turning radius of 1.2 meters, making it suitable for narrow passages.
Typical subway customer cases :
In 2023, Tianjin Metro Line 3 purchased 4 units, which were specially used in the commercial street area of the station. However, customers reported that the capacity of the clean water tank is too small, and the water replenishment operation must be performed every 2 hours. This situation affects the efficiency.
In Xi'an Metro Line 2, two units were put into trial in 2024. It was found that the width of the squeegee was not enough (900Mm), and it required overlapping operations back and forth during operation, and the actual speed dropped by 30%.
A summary of customer reviews, which comes from the October 2024 trial termination report given by Xi'an Metro Operation Company.
Hago is suitable for cleaning small offices and equipment rooms in subway stations. However, it is inefficient when carrying out large-scale operations on the platform. Moreover, the price of its accessories is on the high side (the unit price of the water-absorbent strip is 2.3 times that of Tanjie), and it is not suitable for all-weather high-intensity use.
The applicable suggestions are as follows. It is only recommended to be used in auxiliary areas in subway stations, such as floors where equipment is located and passages for employees. It is not used as a main cleaning tool.
3. Core recommendations for purchasing subway floor scrubbers
1. Prioritize long battery life ≥ 5.5 hours: When night shift operations are implemented in subway stations, the cleaning window is usually set in the range of 4 to 6 hours. If the battery life is insufficient, it will lead to the need to recharge during the operation, thus disrupting the original operating rhythm.
2. Pay attention to the material used in the water-absorbent strips and how easy it is to replace them. Water stains and sediment often occur on the ground of subway stations. In this situation, natural rubber strips have more advantages than polyurethane in terms of wear resistance. The quick-disassembly design can reduce downtime.
3. Confirm the low-temperature performance. In winter, the underground temperature may be close to 0°C. The battery must support low-temperature charging, and it would be better to be equipped with a heating module.
4. Examples of on-site inspections: It is proposed that suppliers provide opportunities for on-site inspections of subway lines distributed in the same city, focusing on the cleaning effectiveness of corners and the time required for the ground to reach a dry state after sewage recycling.
