Features Explained

No-go zones let a robot vacuum avoid marked areas — but the feature has real limits. Here’s how it works, why it can fail, and when to use a physical barrier instead.

Many robot vacuums let you choose a suction mode, commonly labeled something like Eco, Standard, and Max, through a companion app, but the exact names, number of modes, and default setting vary by manufacturer. This guide explains the general trade-off these modes involve (cleaning power, battery drain, and noise), how manual mode selection differs from automatic suction adjustment, and what beginners should check in their own app before assuming any single mode is right for every situation.

Robot vacuums that market “obstacle avoidance” don’t all behave the same way once something is in their path. This guide explains what happens after a robot vacuum detects an object — common reaction patterns, the general categories of objects manufacturers describe recognizing, and why the exact detection scope and behavior vary widely by manufacturer and model — without recommending or ranking any specific product.

Learn what robot vacuum filter types do, how HEPA-style and True HEPA differ, when to clean or replace your filter, and what the filter can and cannot do for your home air quality.

Auto-empty docks are designed to move debris from a robot vacuum’s onboard dustbin into a larger dock-side container, reducing how often the robot itself needs emptying. This guide explains the basic transfer mechanism, the difference between bagged and bagless dock designs, what maintenance is still required, and what beginners should understand before comparing product listings.

A beginner-friendly explanation of what robot vacuum mop features actually do, including how mop pads and water tanks generally work, how water flow and pad motion can vary by model, and what floor-type cautions and maintenance needs beginners should understand before relying on them.

A beginner-friendly guide to robot vacuum suction power, Pa numbers, airflow, brush condition, filters, dustbins, floor types, and why suction alone does not explain cleaning performance.

A beginner-friendly guide to how robot vacuum mapping works, including LiDAR, camera-based, and sensor-assisted methods, what mapping can support, and what it does not guarantee.

A beginner-friendly explanation of robot vacuum sensors, how they support navigation and safety features, and what to compare before relying on sensor-related claims.

A beginner-friendly guide to robot vacuum navigation, including random movement, gyroscope navigation, camera-based vSLAM, LiDAR, obstacle sensors, mapping, and no-go zones.
