iRobot Roomba Discovery Expert Reviews

Picks up superficial household debris well; gets itself out of tight corners; included Virtual Walls let you define vacuuming area; returns to charging dock independently.

Works slowly; misses some spots; no attachments or stair-cleaning capability; occasionally gets stuck.

This robotic vacuum cleaner uses minesweeping technology to do a slow and not entirely thorough job of cleaning floors without your assistance.
