Road cleaning is crucial for maintaining the urban environment, ensuring road safety, and improving air quality, and is widely used in urban roads, highways, construction sites, and mining areas. Currently, water trucks and road sweepers are the two most commonly used core equipment in the road maintenance field.
Although both serve the purpose of road cleaning, their working principles, cleaning methods, and applicable scenarios differ significantly. This article will compare them in terms of working principles, main functions, product advantages, application scenarios, and operating costs to help you choose the right road cleaning equipment.
What Is A Water Truck?
Water trucks, also known as spray trucks or water tankers, are special vehicles widely used in road cleaning, construction, dust suppression in mining areas, and landscaping. Their standard structure consists of a chassis, water tank, water pump, piping, and control devices, and can be equipped with high pressure water cannons, front sprayers, rear sprayers, and side sprayers as needed.
Water sprinkler trucks primarily reduce airborne dust, wash road surfaces, and remove some dirt from road surfaces by spraying water.
Working Principle:
1. Power Take-Off: The vehicle's engine drives a power take-off unit (PTO) via the transmission, transmitting power to the water pump.
2. Water Supply: The water pump draws water from the tank, pressurizes it, and delivers it to the pipeline system.
3. Function Execution: Water flows through different nozzles via valve control to achieve specific functions:
- Front/Rear Spray: Used for road washing, dust suppression, and green space maintenance.
- Side Spray/Water Cannon: Used for long-range spraying or emergency firefighting.
4. Control and Adjustment: The driver adjusts the valve opening via a control device to precisely control the water pressure and flow rate of each spray mode.
Main Functions Of Water Trucks:
- Road Dust Suppression: Reduces dust from roads and construction sites by spraying water mist or streams.
- Road Washing: Uses high pressure water jets to wash away dust and dirt from road surfaces.
- Urban Road Cleaning: Helps maintain the cleanliness of urban roads, squares, and public areas.
- Construction Site Dust Suppression: Controls dust generated by construction vehicles and machinery.
- Landscaping: Provides irrigation water for trees, green belts, and plants along roadsides.
Advantages Of Water Trucks:
- Effectively controls dust over large areas of roads and construction sites.
- Suitable for long distance road spraying operations.
- Can be used on both paved and unpaved roads.
- Multiple operational functions can be achieved through different spraying devices.
- Water tank capacity, water pump, and spraying system can be customized according to user needs.
What Is A Road Sweeper Truck?
Road sweeper trucks are sanitation vehicles specifically designed to remove solid waste, sand, mud, and other debris from roads. Unlike water trucks that rely on water flow for cleaning, they primarily use mechanical brushes and vacuum suction to collect debris into a garbage bin.
Modern sweepers are typically equipped with rotary brushes, a vacuum system, a garbage bin, and auxiliary water spraying devices to suppress dust.
Working Principle:
- Power Drive: The chassis engine drives the vehicle, while the auxiliary engine (or power take-off) drives the superstructure's core components such as the fan and hydraulic pump.
- Mechanical Sweeping: A centrally located rotating brush gathers garbage, sand, and leaves from the road surface towards the center or rear.
- Vacuum Suction: The fan generates a strong negative pressure (vacuum) within the suction cups, drawing the gathered garbage and dust into the garbage bin through a suction pipe.
- Water Spraying for Dust Suppression: During the sweeping and suction cup operations, an auxiliary water pump simultaneously sprays water mist to effectively suppress dust generated during sweeping, preventing secondary pollution.
- Garbage Collection: After the airflow containing garbage enters the garbage bin, it undergoes internal filtration or gravity settling, causing the garbage to fall to the bottom of the bin while clean air is discharged.
Main Functions Of Road Sweeper Trucks:
- Garbage Sweeping: Removing leaves, plastic waste, and other debris from roads.
- Sand and Gravel Removal: Collecting sand, gravel, and mud from road surfaces.
- City Sanitation: Cleaning city roads, sidewalks, and parking lots.
- Industrial Park Cleaning: Removing garbage from roads in factories, warehouses, and industrial parks.
- Highway Maintenance: Removing gravel and other debris from roads that may affect driving safety.
Advantages Of Road Sweeper Trucks:
- Capable of directly collecting and removing solid waste from roads.
- Suitable for daily street cleaning in urban areas.
- Effectively removes accumulated sand, leaves, and other debris.
- Some vacuum cleaner models can collect fine particulate matter.
- Helps reduce road surface deposits from entering the stormwater drainage system.
Water Truck vs. Street Sweeper: Key Differences
Although both types of vehicles are used for road cleaning, their working principles and cleaning capabilities are significantly different.
| Comparison Projects | Water Truck | Street Sweeper |
| Main Functions | Spraying water, dust suppression and road washing | Cleaning and collecting solid waste |
| Cleaning Methods | Water spraying and rinsing | Mechanical brushing or vacuum cleaning |
| Dust Control | Good at suppressing dust | Depends on the cleaning and dust removal system |
| Solid Waste Removal | Limited ability | Strong cleaning ability |

The most fundamental difference between the two is:
Water trucks mainly control dust and wash the road surface by spraying water, while road sweeper trucks mainly collect and remove solid waste through mechanical or vacuum systems.
Therefore, the two types of vehicles are not completely interchangeable.
Which Vehicle Is Better for Different Road Cleaning Applications?
| Application Scenarios | Function Of Water Truck | Function Of Road Sweeper | Recommended Equipment |
| City road cleaning | Spraying water to suppress dust, wash the road surface, and improve the road environment | Clear away leaves, trash, sand, and debris from the road | Used Together |
| construction site | Spraying water to suppress dust and reduce construction dust | Clearing sand, gravel, and construction waste from the construction road | Water Truck |
| Mining area road maintenance | Large scale water spraying to suppress dust on mining area transport roads | Clean up solid debris on paved roads and in work areas of the mining area | Water Truck |
| Highway cleaning | Washing the road surface and helping to control road dust | Remove gravel, mud and other road debris | Used Together |
| Industrial Park Cleaning | Sprinkle water on open areas and roads to reduce dust | Clean factory roads, parking lots and industrial waste | Used Together |
🏷️Summary: If the primary needs are road dust reduction, construction dust suppression, and mining dust control, water trucks are recommended as the first choice; if the primary needs are removing leaves, sand, and solid waste, road sweepers are more suitable. For comprehensive road cleaning projects, using both types of equipment together usually yields better results.
