Home & Lifestyle buying guide
How to choose a robot vacuum
A robot vacuum handles routine floor cleaning so you deep-clean less often. Navigation decides how thoroughly it covers your home, and your floor types, pets and clutter decide which features are worth paying for. It also connects to your Wi-Fi, so privacy and software support matter.

FAQ
Robot Vacuums: common questions
Do robot vacuums work on thick carpet?
Many struggle with deep pile and tassels. Check the maker's guidance and test on your own rugs.
Is mopping worth it?
Robot mopping is good for light upkeep on hard floors. It does not replace scrubbing sticky spills.
Are camera-based robots a privacy risk?
They can be. Check how images are processed and stored, and whether you can turn off cloud features.
