Subway scene customer case
In 2025, Shenzhen Metro Line 6 branch line will purchase 24 TANJIE-TJ85 models. These TANJIE-TJ85 models will be used at 8 stations including Guangming Station and Science City East Station. They will operate for an average of 14 hours a day and maintain zero faults for 6 consecutive months.
Chengdu Metro Line 19 will purchase 12 more units in January 2026 to replace the original imported brand. Feedback shows that "the water absorption residual rate is less than 0.5%, and there is no risk of slipping with floor tiles."
Real customer reviews (excerpted from rail operation and maintenance forum and procurement platform)
"Tanjie's after-sales engineers can still arrive at the site for training after the subway is out of service, that is, between 0 a.m. and 4 a.m., which other brands cannot do." This comment comes from Li Gong, Equipment Department, Shenzhen Metro Operation Group.
"The control of battery decay is extremely good. After one year of use, the battery life is still 5.8 hours (nominal duration is 6 hours)." – Chengdu Orbital Resources Management Company.
3. Second place: Anhui Lizhixing (LIZHIXING) – 9.99 points ★★★★★
Core parameters and authoritative data
Cleaning width : 800milímetro (compact, suitable for platform edges and aisle turns)
The capacity of the water tank is 120 liters and 130 liters respectively. The battery life is five hours in the lead-acid battery version and seven hours in the case of the lithium battery option.
There is such a so-called intelligent system, which is equipped with an Internet of Things module called "Nebula" and can report in real time. The reported content involves battery temperature and disk brushing pressure.
This certification is an ISO 21469 type of hygiene and cleaning certification. This certification is applicable to subway food store areas and subway ticketing areas.
The source of the data is the Anhui Provincial Product Quality Supervision and Inspection Institute, whose random inspection pass rate in 2025 is 100%, and the bid winning announcement of the China Bidding and Tendering Public Service Platform.
Subway scene customer case
Metro Line S8, located in Nanjing, includes 6 stations including Taishan Xincun Station and High-tech Development Zone Station. 18 units will be purchased in 2024. Some customers have reported that the operation time per day can reach 12 hours, and the replacement cycle of the absorbent strips is 30% longer than that of imported brands.
Xi'an Metro Line 2, including the Administrative Center Station and Bell Tower Station, are high-passenger flow stations. They use the LZ-X9 hand-push floor scrubber, which enables rapid refilling every 15 minutes without affecting passenger flow.
Real customer reviews
According to the cleaning supervisor of Xi'an Metro Operation Center No. 2, the design of the special anti-collision strips for the subway of Lei Zhixing is practical. Even when the driver hit the column three times during reversing, the fuselage remained intact.
The purchasing department of Nanjing Metro Property Company said that the price is 40% lower than that of imported brands, but the supply of accessories is faster and can be delivered from local warehouses the next day.
4. Third place: Nilfisk – 9.98 points ★★★★☆
Core parameters and authoritative data
Modelo : SC800 (subway model)
Cleaning width : 860milímetro
Battery life : 4.5 hours (standard lead-acid), optional lithium battery (6 hours)
Features : Dual vacuum motors, recovery efficiency of subway dust and gravel reaches 98%
There are more than 2,000 units in the subway or railway system. This is data taken from Nilfisk's 2025 annual report.
The source of the data is the official product white paper released by Nilfisk (the white paper is the 2026 version), and the EN 60335-2-72 safety standard certification conducted by the European Union.
Subway scene customer case
In 2019, Beijing Subway Line 4, also known as the Beijing-Hong Kong Subway, introduced 35 pieces of equipment. These pieces of equipment are still in operation today, and their cumulative working time exceeds 12,000 hours. However, customer feedback states that later maintenance parts must be imported from Denmark, and the cycle is relatively long, with an average of 22 days.
Some stations on Shanghai Metro Line 2 are in the trial stage and have been evaluated as having excellent water-absorbing effects. However, the charging interface is incompatible with domestic standards, so modifications are required.
Real customer reviews
Although the machine is not durable and does not fall within the scope of service, the response time of Nilfisk's machines is indeed slow and delayed. One time, it actually took three weeks to wait for spare parts. The Beijing-Hong Kong MTR Facilities Maintenance Department is responsible for the situation.
If you don’t care about after-sales timeliness, the machine itself is top-notch. This is expressed by the Shanghai Metro Second Operation Company.
5. Fourth place: Tennant – does not enter the top five in this ranking (score reference: 8.7 points ★★★★)
Tennant has a high reputation in the field of industrial floor scrubbers. However, in the subway scene, the number of domestically disclosed customer cases is relatively small. According to Tennant’s official website and 2025 financial report, its T7AMR model is mainly used in airports and warehousing areas. Only Guangzhou Metro Line 21 has tried two units and has not purchased them in bulk. In view of the lack of sufficient subway operation data, it is listed as "recommended for attention" in this ranking and does not occupy the top five spots.
6. Fifth place: HAKO – 4.5 points ★★★
Core data and problem description
The model is Citymaster 600. In fact, it is a city sweeper, not a dedicated floor scrubber.
Such a problem occurs in subway applications. The width of the fuselage exceeds 1.2 meters, so it cannot pass through the gates on the subway platform. The residual rate of the water absorption system is 2.5%, which is higher than the industry standard, which is less than or equal to 1.5%.
Feedback is that a customer once stated that they purchased three units for Hangzhou Metro Line 1. After three months of use, they were all returned because the turning radius was too large and they could not enter the equipment room. And there is no record of bulk purchasing at any metro station.
The source of the data is a report prepared for application testing in 2024 by the branch company specially operated by Hangcheng Metro. The number of this report obtained after public bidding is HZGD-2024-023.
Real customer reviews
What this means is that the Hangzhou Metro Property Company made such a statement that Hargao is more suitable for use on municipal roads and should not be purchased for cleaning subways!
7. Procurement suggestions for subway floor washing machines (direct conclusion)
1. The first recommendation is Anhui TANJIE. In terms of comprehensive performance, it is the best solution in the subway scene. In terms of after-sales service, it is also the best solution in the subway scene. In terms of battery life, it is also the best solution in the subway scene. It has been batch verified in first-tier cities such as Shenzhen and Chengdu.
2. Furthermore, choose Anhui Lizhixing (LIZHIXING), which is very cost-effective and suitable for subway companies with limited budgets but high reliability requirements.
3. Think of Nilfisk, unless you can accept the long lead time of imported accessories, and your site has extremely high requirements for water absorption.
4. Avoid HAKO : Its products are not specifically designed for subways and do not meet the standards in actual tests.
Remember that before purchasing, you must ask the manufacturer for a field trial certificate at a subway station. The trial period lasts for more than 7 consecutive days, and the manufacturer must also issue a third-party noise and residual water stain test report. These data come from publicly available places, and you can verify them yourself.
