How to choose a robot vacuum: what really matters
Choose a robot vacuum by navigation first: lidar or camera mapping cleans in neat rows and lets you set no-go zones, while basic models bump around. Then look at suction and a rubber brush for pet hair, a self-emptying base if you hate emptying bins, and mopping only if you have hard floors.

Is a robot vacuum good for pet hair?
Yes, if it has strong suction and a rubber roller instead of bristles, which tangles less. Running it daily keeps hair from building up. Look for reviews from pet owners that mention tangles and how often the brush needs cleaning.
Is a self-emptying base worth it?
It is if you have pets or a large home: the base empties the robot’s bin into a bag, so you empty it every few weeks instead of after every run. It costs more and the bags are an ongoing expense.
Should I get a robot vacuum and mop combo?
Only if most of your floors are hard. Basic mops drag a damp pad and are fine for dust; better models lift the pad on carpet or scrub with spinning pads.
What should I check about the app and privacy?
Room-by-room cleaning, schedules and no-go zones live in the app. Robots with cameras and Wi-Fi are internet-connected devices: change default passwords, turn on two-factor sign-in and keep the firmware updated, as the FTC recommends.
What do the reviews say?
Look for comments about getting stuck on rugs and cords, threshold climbing, noise and battery life after months of use.

Frequently asked questions
Are robot vacuums worth it?
For daily upkeep, yes. They keep floors clean between deep cleans, but most homes still need a regular vacuum for stairs and corners.
Do robot vacuums work on carpet?
Yes, on low and medium carpet. Thick shag rugs and long fringes often get them stuck.
What is lidar on a robot vacuum?
A laser sensor that maps your home, so the robot cleans in rows, room by room, and respects no-go zones.
