How does the Roomba robot vacuum find its home base? That’s a super common question that stumps many owners who just got their new robot vacuum.
The Roomba, and many other robot vacuums, use various sensors to navigate around your home and find its way back to the charging station, also called the base station or dock. These sensors can vary, but the most common use light and lasers to get around, with a few even having cameras to see as you do.
We will take a closer look at how a Roomba finds its base and how long it takes for the robot vacuum to return to the dock.
How Robot Vacuums Find Their Base
Most robot vacuums use a combination of sensors, cameras, and mapping technology to find their charging base.
They typically have either an infrared or laser sensor that helps them navigate around your home.
Some robots, like higher-end Roomba’s, come with cameras that map out your floor plan and help the robot vacuum cleaner return to its charging station.
You may even get some robot vacuums that have multiple sensors, so cameras, LiDAR, and IR lights, to help them navigate your home.
2 To 15 Minutes To Find Home
It usually takes the robot vacuum cleaner around 2 to 15 minutes to get back to the base.
However, this may vary depending on how your home is set up.
Other factors like objects can keep a robot vacuum from finding its way back home or have it take longer than usual.
Even bright lights from the sun can confuse the sensors that use IR lights to help the Roomba find its way home. It would be best if you didn’t keep your robot vacuums dock near a window or a spot that gets a lot of sunlight.
Robot Vacuum Can’t Find Its Home
If your robot vacuum can’t find its way back home to its charging station, we have a post that can help you here.
We have several tips and solutions you can use to help fix your robot vacuum navigation problems.
Can Roomba Find Its Way Home in My Apartment?
Your Roomba or any robot vacuum cleaner will likely be able to find its way back to the charging station in your apartment. The same is true for townhomes, RVs, or really any living space. What you live in doesn’t affect the robot vacuum and its ability to get home most of the time.
However, if your home is particularly small or has many obstacles in the way, it may have some trouble finding its way back.
You mustn’t leave too many objects in the way of the robot vacuum, especially things like strings or anything that it could anciently suck up.
Cleaning Distance From Charger
While most robot vacuums can clean for around an hour to 2 hours on a single charge, they need to be in the same area or floor of the charging station to get home and charge.
Many robot vacuums will clean and return home to charge and then clean again once charged back up. This is becoming more common on robot vacuums that empty their own dustbins.
Robot vacuums typically need to be within 6 feet of the base for the sensors to be picked up, so it can find their base station. But the robot vacuum can navigate for 2 to 15 minutes until it finds its “homing beacon.” Many of the higher end robot vacuums will use cameras to remember where they are and where to go to get home, just like you would when using your eyesight.
Not All Robot Vacuums Return Home
No, not all robot vacuums will go to the dock or have a return home feature.
Some robot vacuums have a manual docking mode that you must trigger before the robot vacuum will do so. It may not go to the charging station as it may not have one, but it remembers where you like to keep it and will return there. Though this type of robot vacuum is not common, more commercial and shop robot vacuums often do this.
The robot vacuums that don’t have a return home or a charging base will have a physical cord you must insert into it, just like you were charging your phone. This type of robot vacuum is often on the cheaper end but coming rarer and rarer these days. This was also the style for older robot vacuums before charging stations started becoming mainstream.
Roomba Tries to Dock But Doesn’t Line Up on the Charging Base
If your Roomba is trying to dock onto the charging base but isn’t lining up correctly, you can help it out.
First, try rotating the robot vacuum cleaner so that it’s in the correct position to dock. You may find that there is an angle or sweet spot for Roomba to get back on track. The floor could also be uneven and throw it off, so make sure it’s a flat surface that is sturdy!
Second, make sure the contact points on the bottom of your robot vacuum and base station are clean and free of any debris and gunk. A build-up of dirt or dust can prevent your robot vacuum from making a solid connection with the charging base metal contacts. You need to clean the metal contacts of your robot vacuum regularly and its base station to keep them working correctly; once a month or two should be fine.
Finally, clean the IR windows of the charging station and the robot vacuum itself, as these can get dirty and throw off the alignment. The windows are any clear or black shiny plastic; Use some rubbing alcohol and a clean cloth rag and gently clean them.
