Robot vacuums range from simple bump-and-clean models to self-emptying, mapping-enabled systems at a very different price point. Matching the feature tier to your actual home layout saves you from overpaying — or underbuying.
What to look for
Navigation: mapping vs. random bump
Lidar or camera-based mapping navigates rooms methodically and remembers your floor plan; budget bump-and-clean models just wander. Mapping models clean faster and more thoroughly but cost more.
Suction power for your flooring
Higher suction matters most on carpet; hard floors need less power but benefit more from good edge-cleaning brush design. Match the spec to your actual flooring, not the biggest number available.
Self-emptying base
A self-emptying dock adds real convenience (weeks between manual emptying) but adds significant cost and counter/floor space. Worth it mainly for larger homes or pet owners with heavy debris.
Mopping capability
Combo vacuum-mop models are convenient but generally mop less thoroughly than a dedicated mop. If mopping matters a lot to you, check reviews specifically on mop pressure and pad-washing features.
App and mapping persistence
Check whether the app supports multi-floor maps and no-go zones if you have a multi-story home or rooms you want it to avoid — not all budget models support this.
