Coverage beats peak power
Suction figures are difficult to compare across brands and do not describe brush design or floor contact. A robot that follows an efficient route, reaches edges, and runs frequently can remove more debris than a powerful unit that misses rooms or becomes trapped.
Match navigation to the home
LiDAR mapping is consistent in darkness and creates accurate room plans. Camera systems can recognize obstacles but may raise privacy considerations. Homes with cables, pet toys, thresholds, or dark rugs should prioritize proven obstacle behavior rather than app screenshots.
Price recurring ownership
Replacement brushes, filters, bags, mop pads, and batteries add up. Check whether parts are widely available and whether the app receives updates. Self-emptying docks add convenience but require space and proprietary bags.
