Technical Features


Power goes through the 7 pins PS/2 mini-din that Roomba includes above.Roomba Wi-Fi Remote
RooWifi Wi-Fi Remote for Roomba consumption is about 60mA for voltages next to 17V. This voltage is the power delivered by iRobot Roomba.


iRobot Roomba port connection

The connection and communication with iRobot Roomba robot is done by mini-din connector 7 pin PS / 2 located on the top of the robot. RooWifi Roomba Wi-Fi Remote’s communications protocol incorporates the robot SCI (Serial Command Interface). Setting the communications speed is performed automatically in the ignition process of Roomba Wi-Fi Remote. This communication way permits the configuration to be done completely transparent to the user letting them focus on telemetry commands to control the robot.

Standard Wi-Fi connectivity for Roomba (WPA and WPA2 inclusive)

Wi-Fi Connection

Three working modes:

  • Hotspot mode (Ad Hoc)
  • Home Wifi Network mode
  • Reconfiguration (transient)
The characteristics and compatibility with the Wi-Fi device are as described below:
  • IEEE Std. 802.11-compliant RF Transceiver
  • Encryption: AES128.
  • Networks: Wi-Fi totally compatible with:
    • IEEE Std. 802.11b
    • IEEE Std. 802.11g
    • IEEE Std. 802.11n
  • IEEE Std. 802.1x,  IEEE Std. 802.1u security:
    • Key protected SSID for personal and enterprise Wi-Fi networks.
    • Open security in Hot-Spot mode and for personal and enterprise Wi-Fi networks.
  • Baud rate: 1 y 2 Mbps.
  • Wi-Fi Chipset Radio Certification:
    • FCC for USA
    • IC for Canada
    • ETSI for Europe
    • ARIB for Japan

Flashing Led

RooWifi has a LED to show users in which state the device is working on (referred to the Wi-Fi connection status).

  • Roomba Wi-Fi adapter is ready in Hotspot mode.
  • Roomba Wi-Fi adapter is connecting to Home Wi-Fi network, or
  • Roomba Wi-Fi adapter is ready and connected to a home network.

Restore button

RooWifi enables you to restore the default Wi-Fi mode (Roomba Wi-Fi module in Hotspot mode) manually if any problem exists during the connection or other kind of issue (ex: Forgotten IP address without DHCP).

Multiplatform Interface

The development board allows developers to control the robot through different interfaces or application services:

  • Embedded Web Server.
  • Socket Server / Gateway Mode.
  • Send Clean, Spot and Dock commands using URL through GET AJAX Requests.
  • Read sensors using XML or JSON files.

Embedded Web Server (Standalone mode/Ajax Requests example mode)

User interface can connect to the device via web browser (TCP port 80 –HTTP-). Robot control and configuration is done via web application with access restricted by username and password natively installed on the module. Data is refreshed every 500ms to display telemetry robot online.

Developers Socket TCP/IP (Gateway mode)

Roomba Wi-Fi Remote module has an enabled TCP 9001 port for applications developed as client-server. The device starts working in this mode when port 9001 detects new connection, disabling the web server until disconnected. Baud rate configuration is automatically set and developers are able to use this port just sending SCI commands to control the robot.
