It misses a lot as soon as it senses the wall it turns around so we end up vacuuming too. I bought it on sale as a special buy of the day but wouldn’t buy it again.

It seems to wander aimlessly. However, the battery lasts a long time, so I leave it on until it dies and it does a pretty good job. I only use it on vinyl tile and concrete; no carpet here.
