Roomba Batteries. Although more than a million people have happily welcomed an iRobot Roomba into their homes, one of the biggest issues faced by Roomba owners is its battery life.
It seems that a lot of batteries needed replacing too soon, usually because a charged battery depletes too quickly into the cleaning cycle, and/or could no longer hold a charge, despite repeated attempts.
According to the iRobot website, one Roomba battery can last for hundreds of cleaning cycles before needing a replacement, but only if it is properly taken care of.
These are some specific battery problems and possible solutions reported by owners of the Roomba. (1) The charging process can sometimes be erratic. One reason for this could be an overheated battery. Allow it to cool down, and then begin charging again.
(2) In instances when the power light doesn't illuminate, it may mean that the battery has either been depleted or it's not positioned properly. Reinstall the battery and listen for a ‘click’ sound to ensure that it’s been seated correctly. If this doesn’t fix it, (3) try recharging the battery. If the power light doesn’t illuminate while the robot is on its home base, make sure that (4) all the cords are fully and tightly connected. If all the cords are in place and it still doesn’t light up, (5) try cleaning the charging contacts at the bottom of the robot.
The most common problem, however, is when the Roomba seems to be fully charged, but shuts down too soon into the cleaning cycle.
Should this happen, it is recommended that (6) users try charging the battery from the power supply instead of the home base.
Another common quick-fix solution is to (7) reset the battery, which is done by removing the battery, then holding down the robot’s power button for at least 5 to 15 seconds. The battery should then be reinstalled before the charger is plugged directly into the Roomba.
(8) It is recommended that users do not use the home base to charge so that the charging cycle will not be interrupted. The battery should be charged until the power light is solid green again.
Once the light turns on, (9) the Roomba must be kept on the charger for an additional 72 hours (3 days). It is very important not to interrupt this charging cycle.
After the charging period is completed, (10) run the Roomba in max mode without letting it charge itself until the battery is completely dead. The "dead battery" tune should be heard. This might take several clean cycles in a row. If the Roomba’s performance has not improved, try (11) resetting and cycling the battery from complete charge to complete depletion three more times.
If it has improved, (12) keep doing the reset and cycle several more times until the Roomba runs normally again. Some people also suggest (13) cleaning the Roomba with an air compressor to remove fluff and dust, while making sure to remove the filters and battery first.
To completely avoid problems with the Roomba, however, it is strongly recommended that (14) owners take proper care of their units, as most of the problems that occur within the Roomba are basically caused by negligence.
How to Extend Roomba Battery Life
Here are some tips to extend the Roomba’s battery life.
1) Use the Roomba often.
Since the Roomba uses a rechargeable battery, the battery will last longer when used regularly.
2) Do not unplug the Roomba from its charger between cleaning cycles. The Roomba must be kept charging. Allowing the battery to be completely discharged on a regular basis can cause battery damage.
3) Once every few months, though, the Roomba must be reset and its battery completely depleted. See instructions above for resetting.
4) Additionally, the robot's brushes should always be clean so that the Roomba won’t have a difficult time spinning them. Straining caused by dirty brushes can use up more battery power.
