Robot vacuum Suction Mop Dock Navigation Battery Price $/1k Pa
How to read this. Suction (Pa) is raw pulling power: 2,000-4,000 suits hard floors and light pet hair, 5,000-plus helps on carpet; the giant 20,000-plus figures only matter on thick carpet. Mop: vibrating pads just wipe, while spinning and roller mops with pressure genuinely scrub. Dock: Auto-empty empties the bin for you; an Omni dock also washes and dries the mop and refills water. Navigation: LiDAR maps accurately and cleans in rows, gyro and bounce are cheaper but sloppier, and +AI adds camera obstacle-dodging. $/1k Pa is a rough suction-per-dollar value lens, and the lowest is highlighted, but features usually matter more than raw suction, so filter to what you need first. Note: iRobot and Shark do not publish Pa consistently, so their suction figures are approximate. Prices are USD, converted live.

Common questions

How much suction do I need?

2,000-4,000 Pa for hard floors and light pet hair; 5,000-plus for carpet and heavy shedding. The 20,000-plus flagship numbers only help on thick carpet; for most homes a good dock and navigation matter more.

Is a self-emptying dock worth it?

For most people, yes, it is the biggest convenience upgrade, emptying itself for weeks. An omni dock also washes and dries the mop and refills water. Filter to self-emptying models to compare.

Do the mops work?

Vibrating pads just wipe; spinning and roller mops with downward pressure genuinely scrub, and omni docks wash the pads automatically. It won't replace a deep clean but keeps floors much better between mops.

Is LiDAR better?

Yes, it maps accurately, cleans in efficient rows, remembers rooms and supports no-go zones. Add camera AI to dodge cables and pet mess. Filter to LiDAR for the most reliable cleaning.
