Before buying a robot gadget, consider:
| Feature | Why It Matters |
|---|---|
| Navigation | Laser/LiDAR is better than random mapping |
| Battery Life | More than 90 mins is ideal for large spaces |
| Self-Emptying | Reduces daily maintenance |
| Noise Level | Look for models under 65 dB if you work from home |
| Connectivity | App and voice control are now standard |
