Frequently Asked Questions
What does SLAM stand for and what does it do?
SLAM stands for Simultaneous Localisation and Mapping, and it allows the robot vacuum to build a map of your home as it moves while keeping track of its location on that map.
How does SLAM work in simple terms?
SLAM uses sensors like lasers or cameras to measure distances to walls and furniture, then stitches these measurements into a live map so the vacuum knows where it is and where it has cleaned.
What is the difference between laser-based SLAM and camera-based SLAM?
Laser-based SLAM uses a spinning tower with invisible beams to measure distances and works perfectly in the dark, while camera-based SLAM uses a camera to see landmarks; laser is generally more accurate and less confused by lighting changes.
Why does SLAM matter for a robot vacuum?
With SLAM, the vacuum cleans in neat rows, covers every inch, avoids getting stuck, and lets you view a map on your phone to clean specific rooms or avoid areas. Without it, the vacuum moves randomly and may miss spots or clean the same area multiple times.
Do I need a robot vacuum with SLAM?
For most modern homes, especially those larger than a small apartment or with pets, yes—SLAM saves time because the vacuum cleans efficiently and doesn’t waste battery on random movement.
The bottom line
SLAM is the secret sauce that turns a blind, bumping robot into a smart, organised cleaner. If you want your vacuum to actually remember your floor plan, clean efficiently, and let you control it room-by-room, get one with SLAM — laser or camera, both will change your life. Skip it only if you’re buying a cheap spare for a tiny space. For everyone else, it’s the feature you’ll thank yourself for.
