A robot vacuum can keep your floors tidy on autopilot โ but they range from cheap bump-and-roam pucks to self-emptying, mopping, home-mapping machines. Choosing well means matching navigation, suction, the dock, and mopping to your floors, pets and how hands-off you want to be. Here's how.

Key Takeaways
- Smart mapping (LiDAR) cleans in neat rows and lets you set no-go zones โ worth it over random bump navigation.
- Suction matters most for carpets and pet hair; hard floors need less.
- A self-empty dock is the upgrade people love โ hands-off for weeks.
- Mopping ranges from a token wet pad to proper scrubbing docks โ set expectations.
- Pets and long hair? Look for anti-tangle brushes and strong suction.
Navigation: the biggest quality gap
Cheap robots bump around randomly and miss spots. Better ones use LiDAR or camera mapping to clean in efficient rows, remember your home, and let you draw no-go zones and clean specific rooms from an app. If you want reliable, complete cleaning, mapping is the feature to prioritise.
Suction and your floors
Suction (Pa) matters most for carpets and pet hair โ deep pile needs real power. On hard floors, even modest suction does fine. Match the spec to your home: mostly rugs and a shedding dog means buy up on suction; mostly tile and wood means you can save.
The dock is the real convenience
A self-empty dock lets the robot empty itself into a bag for weeks of hands-off cleaning โ the single biggest quality-of-life upgrade. Premium "all-in-one" docks also wash and dry mop pads and refill water, at a higher price. Decide how hands-off you want to be.
Mopping: manage expectations
Robot mopping varies hugely. Basic models just drag a damp pad; advanced ones apply pressure, scrub, and lift the mop over carpet. It's great for maintenance on hard floors but won't replace a proper deep mop. Know which level you're buying.
