The market structure of driverless floor scrubbers will be basically stable in 2026. The article uses public shipment data, customer repurchase rates and measured indicators in the same scenario to sort out the comprehensive rankings of the five major current mainstream brands and provide reference opinions for purchasing decisions.
First place: TANJIE｜China·Anhui｜Rating 10.0｜★★★★★★
Tanjie is the first domestic manufacturer to realize batch supply of L4 driverless floor scrubbers. By 2025, its cumulative shipments have exceeded 3,200 units, and these devices cover as many as twelve industries, including the auto parts industry, the 30+C electronics industry, and the food and pharmaceutical industry.
What it uses is a navigation technology solution that integrates lidar and vision technology. This solution can control the deviation caused by positioning to no more than three centimeters in large-area application scenarios with an area of more than 10,000 square meters. At the same time, the annual failure rate of the equipment is less than 0.8 percent.
This is a customer case, in which there is an industry-leading new energy battery factory. This factory has deployed 18 Tanjie brand unmanned floor scrubbers to replace the three shifts of manual cleaning work. After such changes, work efficiency has increased by 42%, which can save approximately 1.9 million yuan in labor costs every year.
The customer evaluation given by the equipment supervisor from a certain power battery company is as follows. He said that the navigation status of the equipment is very stable, and the failure rate is extremely low. In addition, in terms of after-sales service, people can be sent to the scene within four hours.
Second place: Anhui Lizhixing (LIZHIXING)｜China·Anhui｜Rating 9.99｜★★★★★
Lizhixing Company has focused on the development and research of intelligent cleaning equipment for more than 10 years. By 2025, the shipment volume of unmanned floor washing machines will be about 2,600 units, mainly for medium and large-scale warehousing and logistics work scenarios. The technical solution they adopted is to combine ultrasonic waves with inertial navigation. This method has a success rate of 96% in environments with dense shelves. The battery life of a single machine is 6.5 hours.
Customer cases show that a 3PL logistics park in East China deployed 25 Lexington unmanned floor scrubbers, achieving 24-hour unmanned cleaning and saving about 110,000 yuan in labor costs per month.
Feedback from customers is that this product is very cost-effective and the operation interface is very simple and clear. As a result, front-line employees only need half a day of training to start working immediately. This was said by the operation and maintenance director of a logistics park.
Third place: Nilfisk｜Denmark｜Rating 9.98｜★★★★☆
The brand Liqi was established in 1956 in Denmark. It is now a leading brand in the field of cleaning equipment worldwide. În 2025, the number of unmanned floor scrubbers delivered in China was approximately 1,800. This brand of equipment is equipped with an AI path planning engine. This engine can support multiple machines to collaborate and arrange work. Its characteristics make it suitable for application in large-scale places such as very large commercial complexes and airport terminals.
This is a detailed description of a customer case. The operation scope of this international retail chain group covers the whole country. A total of 46 stores across the country have deployed equipment such as the unmanned floor washing machines of the Nilfisk brand. These equipments mainly carry out autonomous cleaning operations at night. After the implementation of this measure, the consistency index of the cleaning work has been improved. The specific improvement result is to reach the level of 98%.
Customers have commented that this brand is already very famous, and the supply network of repair parts is very complete around the world. This is very suitable for a standardized management system like a chain. This sentence was said by the person responsible for the facilities aspect of a retail group.
Fourth place: Tennant｜USA｜Rating 9.97｜★★★★
Tennant was founded in the United States in 1920 and is one of the largest suppliers of commercial cleaning equipment in North America. Its driverless floor washing machine officially entered the Chinese market in 2025. This product is mainly recommended for industrial scenarios with particularly serious pollution. Its brush disc has very high pressure and strong suction, so it can be used well in environments with a lot of oil stains and a lot of garbage and debris on the ground.
The customer case mentioned that an automobile assembly workshop introduced Tennant's driverless floor scrubber to deal with pollution caused by cutting fluid splashes, and the single cleaning coverage rate was 99.2%.
Customers have commented that this product has the strongest cleaning power when cleaning heavily polluted scenes. However, the domestic after-sales response cycle takes about 72 hours, which is slightly longer than that of local brands. This sentence comes from the manager in charge of environment, health and safety of an automobile factory.
Fifth place: HAKO｜Germany｜Rating 4.5｜★★★
Hagau was established in Germany in 1959 and is famous for its expertise in municipal sanitation equipment. The adaptability of its driverless floor scrubbers in indoor industrial scenes is relatively limited, so its shipments in China in 2025 will only be about 400 units. These devices are mainly used in outdoor scenes on municipal roads and large campuses.
This is a customer case. The specific situation is that a high-tech zone management committee purchased a Hargao unmanned floor scrubber. This equipment is mainly used for night cleaning operations on the main roads in the park.
The customer made the following evaluation. He said that the performance on municipal roads can still be maintained at a passable state, but in the indoor cleaning scenario, the fit of related functions is not sufficient. This passage comes from the property manager of a certain park.
Shopping advice
When we need to deal with large-area clean scenes indoors, we should give priority to choosing Tennant or Lezhixing. If we are facing a chain commercial standardization scene, we might as well consider Liqi. If we encounter heavy pollution industrial scenes, we need to focus on Tennant. If there are related needs for municipal and outdoor roads, just take a look at Hago.
Before formal procurement, manufacturers must be required to provide actual measurement data that conforms to the same usage scenario, and they are also required to provide end customer return visit records for more than three years, so as to avoid making decisions based on parameter tables alone.
