How to choose a robotic vacuum in 2026

Robotic vacuum Mars Scores weight cleaning performance, navigation, and station capability. The category split for 2026 is: bare-floor robots, vacuum + mop hybrids, and full self-empty/self-wash/self-dry ecosystems. Pick the tier first; spec differences inside each tier are smaller than between tiers.

Suction in Pa is now a flagship spec

Mid-range robots ship 5,000–8,000 Pa; flagships like the Roborock Saros Z70, S9 MaxV Ultra and Dreame X50 Ultra push 15,000–22,000 Pa. Above 10,000 Pa the gains on carpet become real.

Lidar vs camera navigation

has_lidar is the spec that turns "decent" navigation into "magic." Lidar robots map a 100 m² floor in two passes and avoid furniture legs in the dark. Camera-only robots stumble in low light. AI obstacle avoidance (has_ai_obstacle_avoidance) layers on top — it is what dodges socks, cables and pet accidents.

Mopping that actually mops

Spinning mop pads with downward pressure (Dreame X40 Ultra, Roborock S9 MaxV Ultra) clean dried-on stains; passive drag-cloth designs only damp-wipe. Self-wash + self-dry stations eliminate the dirty-pad smell that ruined first-gen hybrids.

Self-empty stations

has_self_empty extends maintenance intervals from weekly to roughly every 6–8 weeks. The iRobot Roomba Combo 10 Max and competing flagships now ship dock-everything stations that handle vacuum + water + mop wash.

Carpet and obstacle clearance

max_climb_height_mm decides whether the robot can cross thick rugs and door thresholds. 20 mm is the safe minimum for typical homes with rugs.
