How to Choose a Robot Vacuum: Features You Should Know

The last thing you want is to spend hours pushing a vacuum around, moving furniture, and fighting with cords. A robot vacuum promises to give you that time back, handling the daily grind of dust, pet hair, and crumbs so you do not have to.

The global robot vacuum market was valued at USD 4.48 billion in 2021 and is projected to grow at a CAGR of over 23.4% from 2022 through 2030, according to Grand View Research. According to recent industry data from WifiTalents, 72% of consumers prefer robot vacuums for routine cleaning tasks. That growth reflects how mainstream these devices have become. But with dozens of models and a wide range of prices, it is easy to feel overwhelmed.
