A robot vacuum is one of the smart appliances people keep using. To actually save time, though, it has to fit your home. Here is a short way through the options.
1. Navigation matters more than suction
A vacuum that maps your home and cleans in neat rows misses fewer spots and bumps into fewer chairs. Laser or camera navigation pays off mostly in larger, multi-room homes.
2. Floors and carpets
Mostly hard floors? Then mopping is worth having. With thick carpets, look for stronger suction and the ability to lift the wet mop automatically.
3. App and smart features
In the Mi Home app you can set no-go zones, schedules and room splits. Check that the model supports what you will really use.
4. Maintenance
Plan on cleaning the brush and replacing filters regularly. Availability of spare parts often matters more than a small difference in suction power.
