Frequently Asked Questions
What is LiDAR in a robot vacuum?
LiDAR is a laser-based sensor that helps the vacuum see and map your home by scanning the room with invisible laser beams to detect walls, furniture, and obstacles.
How does LiDAR navigation work?
It sends out hundreds of laser pulses per second in all directions, then calculates distance by measuring how long each beam takes to bounce back, building a 360-degree picture of the room in seconds.
Is LiDAR better than camera navigation?
Yes, LiDAR works in complete darkness and is more precise and accurate overall, while camera vacuums struggle in low light and can be confused by reflective surfaces like hardwood floors.
Why should I choose a LiDAR vacuum for a larger home?
LiDAR vacuums clean methodically in neat lines and know where they’ve been, so they don’t waste time re-cleaning or get lost—making them ideal for larger homes with multiple rooms and lots of furniture.
The bottom line
LiDAR is the robot vacuum’s secret weapon for smart, efficient cleaning. It’s not essential if you live in a small, simple home, but for most households—especially larger ones—it’s the feature that transforms a robot vacuum from ‘random bumper car’ to ‘genuinely useful home helper.’ If you can stretch your budget, LiDAR is one of the upgrades we actually recommend. It genuinely works better, and you’ll notice the difference every single day. Your home will be cleaner, your vacuum won’t get stuck as often, and you won’t spend your evenings watching it hopelessly confused in the corner of your bedroom.
