What is the iRobot Roomba 870 robot vacuum cleaner? This model offers extensive functionality and improved technical specifications. Although there are newer robots in the 800 series, this vacuum cleaner remains popular due to its lower price—around $265 in 2019 (for comparison, the 896 Roomba costs $34,500). The iRobot Roomba 870 review confirms all its capabilities.

Components of the 870 model
Design
The iRobot Roomba 870 robot vacuum cleaner stands out from its predecessors with its new design. Its distinctive features include rotary rubber brushes and a high-performance turbine. Its appearance is similar to its competitors: the same round shape with sloped edges. The body is made of black plastic, typically matte. The perimeter and top of the panel are made of silver plastic.
Top view
In the center of the top of the body is a panel covered in tinted translucent plastic. Hidden beneath it are LED indicators. And in the very center of this panel is a large button for activating the robot vacuum. When the iRobot Roomba 870 is active, this button glows green. Also on the body is a retractable handle for carrying the robot.
Side view
The lower bumper is equipped with a rubber trim to prevent damage if it collides with furniture. The upper bumper is framed by a black translucent plastic, which houses IR sensors. A sensor mounted on top of the bumper allows the iRobot Roomba 870 robot vacuum to detect the height of furniture and objects it can reach under.
A look at the robot's underside reveals its key features: two rubber brushes that rotate in opposite directions, as well as a powerful suction system. A side brush, two main wheels, and a guide roller are also visible. The iRobot Roomba 870 is equipped with sensors around its perimeter that detect changes in height to prevent the robot from falling down steps or other heights. Next to the rotary brushes is a waste container that collects all debris.

Functional capabilities
The main feature that distinguishes the device from similar devices is the AeroForce cleaning system. This system includes three functions:
- Two rotary brush rollers. These rubber brushes rotate toward each other, sucking up more debris into the container. Because they have maximum contact with the surface being cleaned, they effectively remove lint and fur not only from smooth surfaces but also from carpets.
- Powerful vacuum turbine. The iRobot Roomba 870 robotic vacuum cleaner now removes five times more debris from the floor thanks to this turbine.
Powerful suction system
A review of the cleaning modes reveals that the robot can independently identify heavily soiled areas. Furthermore, the Roomba 870 can be programmed to clean on a specific day and time. Another advantage of this model is its indicator that notifies when the dust bin is full. Two virtual walls can also be used to define the cleaning area.
It's worth noting that the iRobot Roomba 870 differs significantly from the Roomba 880: the most important difference is that the 870 model lacks a radio module and, therefore, doesn't support beacons, only a virtual wall. Furthermore, the 870 model doesn't come with a remote control, while the newer robot does. Finally, the updated model's cleaning area reaches 120 square meters, while the Roomba 880 can clean up to 80 square meters.
Operating instructions
The user manual provides detailed information on how to properly maintain your robot vacuum cleaner, troubleshoot the most basic malfunctions using error codes, and, of course, how to use the device.
