Most robot vacuums can pick up sand without any issues. However, the ones with rotating brushes are typically better at picking up sand than models without them.
The double brushes found on Roombas work the best for picking up sand – especially in cracks and crevices.
In general, robot vacuums are great at picking up sand and dirt off the floors and carpets. However, there are a few things that can keep them from performing at their best.
One of the biggest issues is clogging. Sand can easily clog up a vacuum’s filter – whether it’s a traditional upright vacuum or a robot vacuum.
Another issue is hair, if enough hair is wrapped around the beater brush, it can stop it from scooping the sand into the robot vacuum. So it’s important you keep the brushes of your robot vacuum clean.
The brushes also wear out over time, they get shorter, so make sure to replace them at least twice a year if not more.
How Well Robot Vacuums Pick Up Sand
A robot vacuum won’t be as powerful as your regular vacuum and may require multiple passes to pick up the sand, but it will get most of it.
To show this, a YouTuber has made a great video of a Roomba picking up different kinds of sand in his home.
Smart Enough – Dirt Vs. Sand
Most robot vacuums have sensors to detect dirt it’s picking up, but the sensor is not smart enough to determine if it’s sand or dirt. To the robot vacuum, it’s all the same.
The way the sensor works is that it’s listening to the items being sucked up and if it hears a lot more than usual it knows it’s over a dirty spot and will spot clean that area more. You’ll see this when the robot vacuum tries to pick up sand clumps.
Robot Missed The Sand!
If your robot vacuum misses sand, one of the first things you should check is to make sure its dust bin is not too full, the filter is clean, and the brushes are not clogged.
If everything seems fine, then the robot vacuum may need a second go at the spot. You can place the robot vacuum over the sand and tell it to spot clean and let it do its thing.
Unless the sand is super wet, it should pick up the sand given enough time to work.
How Often To Run Your Roomba If Sand Is An Issue
If you live somewhere that has a lot of sand, then it’s best to run your robot vacuum every day to pick up the sand.
Sand can get everywhere, and having a robot vacuum to pick it up is a lifesaver. I even know people who will take their Roomba on vacation for this very reason!
