  • Page 5: 01: Customer Call

    Roomba issues can be diagnosed over the phone by guiding a user through a troubleshooting process. At a minimum, iRobot recommends that the customer be asked to perform routine Roomba maintenance steps to resolve the Roomba issue. Only if these steps fail to resolve the issue should a customer send the Roomba to a service center.
  • Page 6: 02: Roomba Return Procedure

    02: Roomba Return Procedure If the initial maintenance steps did not solve the issue, a customer should proceed to return the Roomba, battery and all accessories to a service center. IMPORTANT : Before packing and shipping a robot, clear all schedules by resetting the Roomba : Press down the SPOT and DOCK buttons simultaneously for 10 seconds.

  • Page 15: Roomba Cleaning Behavior And Technology

    Roomba Cleaning Behavior and Technology The Roomba (500 Series) has three cleaning modes and will clean based on the cleaning mode you select. Clean Mode : Roomba automatically calculates the room size and adjusts its cleaning time appropriately. Spot Mode: Roomba will spiral approximately 3 feet in diameter and then spiral back to where it started, intensely cleaning a localized area.
  • Page 16 Normal Cleaning Behavior In normal cleaning behavior, Roomba switches between several different behaviors: o Drive – Roomba drives straight o Spiral – Roomba drives in an outward spiral pattern o Bounce – Bumper activation makes Roomba back up, turn in place, and drive straight o Wall follow –...
  • Page 17: Service Procedure (Based On Built-In-Test Failures)

    Service Procedure (based on Built-in-Test Failures) Every Roomba that is serviced is required to undergo a Built-in-Test (BiT) which will then dictate how to best service the Roomba. A Roomba needs to pass the BiT before being returned to a customer. The following process is based on failed BiT steps or specific symptoms.

  • Page 22: Roomba Battery

    Roomba Battery Roomba is powered by a soft pack rechargeable NiMH (nickel metal hydride) battery made up of 12 cells. The battery can only be accessed by removing the bottom plate of the Roomba. A fully charged battery has a voltage between 15.5 and 18 V. The battery also has a thermistor and it relies on the change of resistance to measure battery temperature.
  • Page 23: Roomba Power Supply

    Roomba Power Supply Roomba’s are charged by either a Universal (100-240V) or Domestic (120V) Power Supply. The Power Supply steps the voltage down to 22.5VDC and 1.25A. A solid green LED light on the Power Supply is an indication that it is plugged in and operating properly. Roomba 500 Series Charging Algorithm Overview High level sequence 1.
  • Page 24 o Normal Charge Timeout : 9 hours maximum in normal charge mode. o Recovery Charge Timeout : 16 hours maximum in recovery charge mode. o Temperature Max : Battery temperature exceeds 60° C for at least 1 minute. o Voltage Max : Pack voltage exceeds 21.6V for at least 1 minute. o Previous end-of-charge : If a battery has been discharged by less than 150mAH since the last complete charge.
  • Page 25: Roomba Home Base

    Roomba Home Base The Roomba Home Base is a self-charging station where the Roomba (through a sophisticated infrared tracking mechanism) can drive back to at the end of a clean cycle or when its battery is low. After docking itself, the Roomba will recharge its battery. The charging sequence takes about 3 hours in a normal charge and 16 hours in a recovery mode.
  • Page 26: Manual Docking

    Roomba needs to find the infrared signal of the Home Base in order to return so it is necessary to always keep the Home Base plugged in. The Home Base should be placed on a hard level surface and in an area where Roomba has a clear path to return to the Home Base at the end of a cleaning cycle. If Roomba is unable to dock on its first attempt, it will try again until it successfully docks.

    Roomba Virtual Wall The Roomba Virtual Walls create an invisible barrier that Roomba will not cross. The Virtual Walls can be set to block an area ranging from 0 to 2.4 meters long. Light Houses turn off automatically after 2 hours. Force Field Emitter (Avoid collision) Infrared Beam Emitter...
  • Page 29 Virtual Wall Troubleshooting • If the Virtual Wall is turned on but the battery status light is off or flashing, the batteries are low. Check the batteries and the virtual battery door. When replacing batteries wait 5 seconds between removal and insertion for a full reset. Also, choosing a higher range in Virtual Wall than necessary will drain the battery faster.
  • Page 30: Roomba Virtual Wall Light House

    Roomba Virtual Wall Light House Light Houses help Roomba navigate around a home, helps Roomba find the Home Base, and allow Roomba to clean one room before starting the next. There is a mode selector to choose either Virtual Wall or Light House mode. In either mode, the Light House will automatically turn ON when the Roomba is on and within radiofrequency range (~15 meters).
  • Page 31 Light House Troubleshooting o Complaint : Customer gets a new Service Roomba (models 535 and above) and the old Light Houses stop working properly. Solution : Have the customer remove all the Light House batteries and reinsert them (flushes Light House memory). Background : When a customer first uses their new Roomba, all new Light house within RF range will turn on.
  • Page 32: Roomba Wireless Command Center (Base Robot 3.4 And 3.5 Only)

    Roomba Wireless Command Center (Base robot 3.4 and 3.5 only) The Wireless Command Center allows a user to remotely turn the Roomba on or off, be directed and scheduled. To schedule a Roomba to clean, use the buttons on the Wireless Command Center as if they were on the robot user panel itself.
  • Page 33: Roomba 500 Series Errors

    Roomba 500 Series Errors Roomba 500 Series Pause Errors(‘uh-oh’ + beeps) When a Roomba experiences an error it will stop cleaning and emit an error. A pause error will always have an “uh-oh” followed by beeps and perhaps even a voice message. The beep errors can be replayed by hitting the bumper.

  • Page 44: Auto-Advance Mode

    AUTO-ADVANCE MODE This is designed to be used on the assembly line. In this mode, the robot internally decides PASS/FAIL for each test number. The test advances automatically so each sensor or actuator is tested only once. In AUTO-ADVANCE mode: o Activate the sensors for each sub-test in order as described in the chart below.
  • Page 45: Data Collection

    The robot CANNOT be powered off and will not respond to any buttons until the BATTERY IS REMOVED (do not do this unless the procedure calls for it). DATA COLLECTION In both manual and automatic advance modes, data can be collected by connecting a serial cable under the face plate to the computer.
