Key Features to Look for in Budget Robot Vacuums

Before diving into specific models, it’s essential to understand the features that matter most in budget robotic vacuums:

• Navigation and Mapping: Basic models use random navigation, while more advanced ones offer smart mapping for efficient cleaning paths.

• Dustbin Capacity: A larger dustbin reduces the frequency of emptying, making maintenance easier.

• Floor Type Compatibility: Ensure the vacuum works well on your floor types, whether hardwood, tile, or low-pile carpet.

• Smart Features: Wi-Fi connectivity, app control, and voice assistant compatibility add convenience.

• Mopping Functionality: Some budget models include a water tank for light mopping, adding versatility.
