iRobot Roomba 880 cliff, ledge, bin, bumper sensors

iRobot Roomba 880 sensors types

iRobot Roomba 880 was 5-stars rated by many customers. It has four front and two rear cliff sensors (iRobot won’t fall down stairs), two bin sensors, bumper sensor (touch-sensitive, iRobot won’t damage furniture, walls and other obstacles), optical, RCON (Room Confinement Sensor) sensors.

Dirt Detect 2 includes acoustic and two optical sensors to find dirt and debris. Acoustic sensor (piezoelectric) determines noise level near places with highest concentration of dirt and then spends more time cleaning them. Two optical sensors (IR emitter and receiver) registers dirt as it hits the brush, to measure the how much dirt being sucked through the machine.

Cliff sensors (which identify when it’s too close to a ledge (stairs and steep drops)).

iRobot Roomba 880 has Self-Charging, Multi-Room Navigation, Scheduling, Tangle-Free Debris Extractors, 3-Stage Cleaning System, AeroForce 3-Stage Cleaning System (5x the air power) functions.


Programming this robot is a breeze. Select the day, enter a time, and click the “OK” button. As long as you’ve set the clock properly, this machine will trundle off on a cleaning run and go back to base when finished, or run out of battery power.

This robot is able to clean several rooms on a single charge, spending a maximum of about half an hour in each room before moving on to the next one. It’s two “Virtual Wall Lighthouses” help stimulate a virtual wall in doorways to prevent the robot from entering the next room until it has cleaned the first.


This Roomba cleaning robot cleans well, but not as well as a human might. It cleans with continuous little clicks and beeps. The central suction band and spinning brush perform a solid job of cleaning even the edges of your rooms. Also, this robot comes with a remote control which can be used to steer the robot towards really dirty patches.


The bin, drop sensors, front wheel and air filters all require regular maintenance on, at least, a weekly basis.

Pros: Hassle-free cleaning, easy programming and maintainance, effective cleaning, remote control.

Cons: It’s quite expensive and will require an additional cleaner for the attachments for uses such as cleaning stairs. It also requires filter changes.
