Robot Vacuum Buying Guide: Everything You Need to Know
From suction power to smart mapping - learn how to pick the perfect robot vacuum for your home.
The Ultimate Robot Vacuum Buying Guide
Robot vacuums have evolved from simple gadgets to sophisticated cleaning machines. Here is everything you need to know to choose the right one for your home in 2026.
1. Suction Power
Measured in Pascals (Pa), suction power determines how well the vacuum picks up debris. 2000Pa is the minimum for carpets, while 4000Pa or higher is recommended for homes with pets or thick carpets.
2. Navigation Technology
LiDAR navigation is the most accurate, creating detailed maps of your home. Camera-based systems (vSLAM) are good alternatives. Avoid models with random bump navigation as they are inefficient and miss spots.
3. Smart Features
Modern robot vacuums offer app control, multi-floor mapping, no-go zones, scheduled cleaning, and voice assistant compatibility with Alexa and Google Assistant. Some models can even recognize and avoid obstacles like pet waste.
4. Self-Emptying Base
Premium models like iRobot Roomba j7+ and Roborock S8 Pro Ultra include self-emptying bases that can hold weeks of debris, making them truly hands-free.
5. Mopping Function
2-in-1 vacuum and mop combos offer excellent value for homes with hard floors. Look for models with automatic mop lifting for carpets and self-cleaning mop stations.
