How well does the Whisper 2000 robot vacuum avoid small obstacles like LEGO bricks?

The Whisper 2000 navigated around a single LEGO brick during testing, using LiDAR and a front camera. That’s genuinely impressive for a robot vacuum, considering how small those plastic landmines are. It won’t save every stray sock or charging cable, but it passed the brick test — the gold standard for “will this eat my kid’s toys?”
