Key buying factors
Higher Pa means better pickup on carpets. We recommend at least 2500 Pa for pet hair.
Look for low wattage and smart scheduling to reduce electricity use.
Extends hands-free time; some models empty into a bagless bin.
LiDAR or gyroscopic navigation improves coverage and reduces missed spots.
2-in-1 vacuums can wet-mop hard floors, but require human intervention for water tank.
HEPA filters and tangle-free brushes reduce upkeep cost and improve air quality.
Types explained
Simple models with random navigation and no smart features. Suction is moderate.
Best for: Small apartments with hard floorsIncludes a base station that automatically empties dustbin, extending autonomy.
Best for: Busy households who want maximum convenienceEquipped with a water tank and mopping pad for simultaneous sweeping and wet cleaning.
Best for: Homes with sealed hard floors and light daily mopping needsCare & usage tips
Empty the dustbin after each use if no self-emptying base. This maintains suction and reduces allergens.
Remove hair from side brush and roller weekly. Wipe cliff sensors and charging contacts monthly.
Change HEPA filters every 1-2 months, and replace roller brushes every 6-12 months for optimal performance.
Our testing confirmed that in this price bracket, self-emptying and strong suction are trade-offs-you usually get one or the other. The Kilgone strikes the best balance with 6000Pa and a self-emptying base, but the eufy C10 offers longer autonomous cleaning at the cost of lower suction.
To maximize battery life and cleaning efficiency, schedule your robot to run during off-peak hours when it can return to charge mid-cycle. Pair with a smart plug to cut standby power.
