Error forty three (43) means Roomba i Series is stuck in the infrared (IR) beam of a Virtual Wall® or Home Base®. Move Roomba® to a new location, and then press CLEAN to restart.
Place your Roomba® back onto the Home Base® and attempt another direct cleaning job. If the message persists, try moving your Home Base to a different location and start Roomba® from the Home Base®. Environmental interference may prevent Roomba® from navigating as expected.
Error forty three (43) means your j Series robot started a job in a Keep-out Zone. The robot places a small keep-out zone around the Home Base by default. Move your Roomba® to a new location, then press the button to restart the mission. For more information, please contact iRobot Customer Care.
You can easily check the status of the battery in the iRobot® HOME App. A battery icon will be displayed in the top-right corner, indicating the current status of the battery.
With proper care, your robot`s battery should last at least 2-3 years before it needs to be replaced. Here are some battery maintenance tips to extend battery life and keep Roomba® cleaning at peak performance: Only use iRobot® batteries.
If your Roomba® i Series Robot Vacuum is not turning on or is not able to charge, rebooting your robot tends to solve most related issues. To reboot your Roomba: Press and hold the CLEAN button for 20 seconds. After you release the button, the light ring will show a white clockwise swirl while it reboots.
This error is generated by the mobile network and it indicates that the network is not able to handle the message traffic from the modem.
Error forty-two (42) means that your Roomba® failed to re-localize during a direct cleaning job using Smart Maps and the map may also appear to not look correct in the app.
Error 21 means the robot is experiencing an internal communication error. Press CLEAN to restart the cleaning mission. If the message persists, perform a robot reboot, and test again. If a reboot does not clear the error, try removing the battery.
Error thirty (30) means the vacuum is experiencing insufficient airflow. It is recommended that you clean or replace the bin filter. Then try to run the robot again.
The number of cycles depends on factors like how often you use your robot vacuum and the climate. However, our research shows you can expect a nickel battery to last around 400 cycles or up to two years, and a lithium battery can withstand around 1,500-2,000 cycles or up to five years.
Dirt or built-up debris may be preventing your robot from charging. Please unplug the base and grab a clean, lightly dampened melamine foam, such as a Magic Eraser to clean the contacts on the robot and base. Watch the following video outlining steps for cleaning the charging contacts.

The function of the battery is to store, and provide electricity to the entire device. The average run time of the iRobot Roomba i7 is 1 hour and 15 minutes.
Factory reset on a Wi-Fi Connected Roomba® and Braava jet®

e Series Robots: Press and Hold the Home and Spot Clean and CLEAN button down for 20 seconds then release. 900 Series Robots: Press and Hold the Dock and Spot Clean and CLEAN button down until all LEDs illuminate.

It may take up to a minute and a half for your robot to reboot. The reboot procedure is complete when the light ring shuts off. Note: For 600 series robots, see below. Note: A robot reset will reset the clock of a non-connected robot.
While the iRobot® HOME App provides many benefits, a Wi-Fi or App connection is not required for Roomba® and Braava jet® to clean. For Roomba®, Clean, Dock, and Spot Clean do not require a connection to the app.
Pulsing red: Charging, too low to start cleaning. Solid red: Error (tap Clean for details). Red sweep toward rear: Empty the bin (s Series), Filling the tank (m Series) .
Error 7 means the side wheels cannot turn. This can happen if Roomba i Series was started on an uneven surface or got stuck on an obstacle. If this is the case, lift Roomba off the floor and place it in the center of the room and restart the clean cycle. Use Dual Mode Virtual Wall® Barriers to block off problem areas.
A Roomba uses its piezoelectric sensor as a dirt detector. When bits of dirt hit the sensor, the Roomba receives tiny electric impulses. Enough impulses will prompt Roomba`s dirt detect to kick into gear – a second, more thorough cleaning of the area.
If dirt or other contaminants enters the vacuum pump chamber or valves, overall pump performance can be impacted. When pumps need more time to accomplish operations, they may be in danger of failing. At this point, thoroughly cleaning your pump and ensuring that no contaminants reach other parts is a necessity.
Typically, a vacuum leak will cause situations like hard starting, rough idle, excessive fuel consumption, and engine codes. You might even be able to hear a leak – sometimes a whooshing or whistling sound can be heard with the engine running.
Loose connections will cause your vacuum cleaner to lose suction. Make sure that the dust container, the hose, the tube and the brush are all attached properly. If the problem continues, your vacuum cleaner might have a technical problem. If you suspect this to be the case, contact an authorised service agent.

I purchased a brand new P113 Ryobi charger about 2 years ago. It has never worked. If I put a P104 battery in for a charge, it looks like it works correctly. I push the battery tester on the battery itself, and it says full charge, but when I go to use the bateery, it dies right away. I have tried three new P104 batteries. The batteries charge on my charger at work with no problem. The funny thing is, I don't need a battery in the charger and the charger does the same thing, It runs the test
ANSWER : If you have your receipt, check with Ryobi to see if it is still under warranty. It comes with either a 2 or 3 year warranty, depending on when it was purchased. If it is still covered, get it replaced/repaired. If it is not, buy the P117 charger. $30 at Home Depot. It has a 90 day satisfaction guarantee. If it charges your batteries properly, you’re good. If not, bring it back if you don’t like/want it. My P113 won’t get out of test mode now, or charge Lithium batteries anymore. So I bought the P117 yesterday. Works great, and it’s a lot cheaper than new batteries! And it has a 3 year warranty.

Battery charge I just purchased a new battery pack insert for my Roomba, Replacement
was a breeze and it now works great. My question is; The last battery I
bought ( not from you) was a full cased roomba battery pack that didn’t
last a year. Roomba says leave the r Roomba charging all the time so
it’s ready when you need it, and that’s nice but I feel that leaving it
charging like that it will kill the battery faster as it is always warm
to the touch. These battery’s should last at least 5
ANSWER : Dave you are correct. You should never over-charge anything like a Roomba, Cel Phone, etc. That will kill a bettery very quickly.

Seems to charge but then wont come on
ANSWER : Sounds like you bought a defective battery
You can test for this by removing the battery.and holding the power button for 15 seconds. This will restart the.charging cycle as if the battery were new. If it still goes red get a refund and a new one.

Can you take the Swivel Sweeper battery pack apart to replace the batteries with new rechargeable batteries? Batteries look like AA or AAA, but it appears that the battery pack is sealed. Is there any way to get it apart:?
ANSWER : Yes you can if you have a way to cut through the plastic outer case,(I used a Dremel rotary tool). Inside you will find six double A Ni-mh batteries. I found eight of these for sale on ebay for around ten bucks,then all you do is solder some wire to the batteries like the original battery pack and tape up the case and charge.
