Is a cordless vacuum better than a robot vacuum?

A cordless vacuum is not universally "better" than a robot vacuum; instead, they serve completely different roles in a home.

• Choose a cordless vacuum if you need high suction power for carpets, want to clean stairs, furniture, or cars, and need to quickly clean up sudden spills.
• Choose a robot vacuum if you want automated, daily maintenance on hard floors or low-pile rugs to keep pet hair and dust under control without manual effort.

For most households, these devices are complementary. If you can only buy one, a cordless stick vacuum is generally the safer primary purchase because a robot vacuum cannot clean couch cushions, stairs, or tight vertical spaces.
