Lidar and camera robots map your home and clean in rows. Random-bump robots are cheaper but miss spots and take longer.

Vacuum only or vacuum and mop

  • Mostly carpet: vacuum only
    – Mixed floors: vacuum and mop with mop lifting
    – Mostly hard floors: a mop-washing dock is worth it

Docks

Self-empty docks hold weeks of dirt. Mop-wash docks clean and dry pads. Both take floor space, so measure first.

Running costs

Budget $50 to $150 a year for bags, filters, side brushes and mop pads.

How to choose robot vacuums: the short version

Pick lidar or camera mapping, decide whether you need mopping, choose a self-empty dock if you hate emptying bins, and check yearly supply costs before you buy. This robot vacuums buying guide explains the features that matter, the ones you can ignore, and which models we would buy or skip.

Our shortlist: the Roborock Qrevo S Robot Vacuum and Mop ($499–$799) for most homes. the Shark AV2501S AI Ultra Robot Vacuum ($299–$449) for pet hair on a budget. the eufy Robot Vacuum Omni C20 ($399–$599) for small homes and under furniture.

How much should you spend on robot vacuums? Budget models start around $199, while premium options reach $1,599. Spending more usually buys self-emptying, self-washing mop dock for less and bagless self-empty base and strong pickup, but it is only worth it if you will use those features.

Lidar or camera navigation creates maps and cleans in efficient rows. Self-empty docks mean you empty the robot weeks apart instead of daily. Mop-washing docks keep mops fresh; vacuum-only robots suit carpet-heavy homes.

Yes for most homes. They keep floors clean between deep cleans, especially with pets. They do not replace a stick vacuum for stairs and edges. Yes on low and medium pile. Thick shag rugs and fringe can trap them.

Robot vacuums get some of their deepest discounts on Prime Day and Black Friday. Check the cost of replacement bags and pads, and confirm the dock fits where you plan to put it.

Across the robot vacuums we cover, typical prices run from $199 to $1,599. Store prices change often, so treat these as typical ranges and check the current price before you buy.

Also worth a look is the Roborock Saros 10R, usually $1,199–$1,599, which is best for premium all-in-one. Its standout feature is ultra-slim with top obstacle avoidance; the main trade-off is very expensive. At around $199–$274, the iRobot Roomba 694 suits shoppers who want basic, long-running Roomba. Owners and specs point to simple app and proven basics, while random navigation without maps is the catch.
