BMR Floor Grinding Robot 850S
A grinding crew spends long hours walking the same straight lines behind a heavy machine, and every pass depends on how steady a pair of hands stays. The BMR Floor Grinding Robot 850S changes that routine. It scans the room, plans its own route and grinds without a person steering it, so the crew can spend its attention on inspection, edges and scheduling.
The product is available through this page, by quotation.
Background
The maker behind the 850S
The BMR Floor Grinding Robot 850S is made by Shenzhen BrightMaster Robotics Co., Ltd., sold under the BMR brand. The company builds robots for construction-site floor work, and the 850S sits alongside the other floor machines in the same range, such as the BMR Floor Coating Robot and the BMR Floor Screeding Robot. Together they cover several steps of a floor job, from leveling and screeding to grinding and coating.
Within the grinding line there are two versions: the 850M and the 850S. This page describes the 850S, and every figure below belongs to it unless it is marked as shared by both versions.
What the 850S is built to do
The 850S is designed to remove surface laitance from concrete. Laitance is the weak, powdery layer that rises to a freshly finished slab. It has to come off before a coating, hardener or terrazzo finish can bond properly. Doing this by hand-guided machine is slow and tiring, and the result varies from one operator to the next.
The robot handles this with LiDAR scanning. The scanner identifies walls, columns and other fixed objects. From that information the robot carries out intelligent path planning, real-time positioning, autonomous navigation and fully automatic grinding. Other listed functions include safe stopping when an obstacle is detected, grinding disc protection, construction data statistics, fault alarm and FMS cloud data management.

What makes the 850S different from the 850M?
The two versions share one platform. Voltage, power supply type, frequency, grinding power, working width, planetary disc, travel speed, battery, operating range and positioning accuracy are listed once for both. The differences lie in the body and in the grinding speed range. The 850S has a grinding speed of 0-2000rpm and weighs 627kg, with dimensions of 1520X866X1204mm. A smaller, lighter machine is easier to move between rooms and to position at the start of a shift.
Dust handling is the other point to check. Automatic dust collection is listed for the 850 M series, and no dust collection power figure is published for the 850S. A buyer who wants the machine to manage its own dust should look at the BMR Floor Grinding Robot 850M as well, and should ask about dust control for the 850S when requesting a quotation.
How does the 850S find its way around a site?
The robot relies on LiDAR scanning rather than a guide rail or a manual route. The scanner reads the position of walls and columns, and the software turns that into a grinding path. Positioning accuracy is 5cm. The robot knows where it is in real time and can follow its plan across a large floor without a person correcting it.
If something enters its path, the robot stops safely on detecting the obstacle. Grinding disc protection and fault alarm add further layers, and construction data statistics together with FMS cloud data management give a site manager a record of what the machine has done. For a contractor who has to report progress, that record is useful beyond the grinding itself.
Who is the BMR Floor Grinding Robot 850S for?
Flooring contractors are the first group. They grind large slabs repeatedly, and an autonomous machine standardizes the pass pattern while taking the pushing and vibration away from the crew. General contractors who handle floor preparation themselves before coating or hardener work will find the same benefit.
Facility owners and developers of parking garages, factory workshops, warehouses, laboratories, sports venues and commercial buildings are the second group. Their floors are wide and open, and the work is repetitive. A robot with a working width of 850±50mm suits that kind of area.
Buyers who need the lighter, more compact body will lean toward the 850S. Those who want automatic dust collection built into the machine should compare it with the 850M. Companies building a wider robotic fleet can browse the Flooring Robots category or the wider Construction Robots range.
What is the BMR Floor Grinding Robot 850S used for?
- Removing surface laitance. The machine strips the weak surface layer from concrete before the next finishing step.
- Preparing epoxy floors. Epoxy surfaces are among the floor types the robot is used on.
- Working sealed hardener floors. Both sealed hardener and emery sealed hardener floors are on the list.
- Grinding terrazzo. Epoxy terrazzo, inorganic terrazzo and terrazzo floors can all be ground with it.
- Covering large open areas. Autonomous path planning keeps passes consistent across wide slabs.
- Recording site progress. Construction data statistics and FMS cloud data management let managers follow the work.

Frequently Asked Questions
What power supply does the 850S need?
The shared specification lists 380 VAC, a three-phase five-wire system, at 50 HZ/60 HZ. Confirm your site supply when you request a quotation.
How wide is the grinding path?
The working width is 850±50mm, and the grinding power is 18.5kW with a planetary disc.
How fast does it travel?
The travel speed is 0.5m/s, and the grinding speed is 0-2000rpm on the 850S.
How does the robot navigate?
It uses LiDAR scanning to identify walls and columns, then plans its path and positions itself in real time. Positioning accuracy is 5cm.
Can it climb slopes?
Yes. The climbing figure for the 850S is 15°.
Does the 850S have automatic dust collection?
Automatic dust collection is listed for the 850 M series. No dust collection power is published for the 850S, so please ask about dust control when you request a quotation.
Where can I buy the BMR Floor Grinding Robot 850S and what does it cost?

Summary
Hand-guided grinding asks a person to repeat the same walk for hours. The BMR Floor Grinding Robot 850S replaces that walk with LiDAR scanning, planned paths and automatic grinding, and its body is the smaller and lighter of the two versions in the line. It removes laitance from concrete and works on epoxy, sealed hardener, emery sealed hardener and terrazzo floors. Questions on dust handling and the unpublished specifications are settled when the quotation is prepared. If this machine fits your floors, this page is the starting point.
