The X20+ squeezes a full all-in-one dock and capable obstacle avoidance into an aggressive price point — ideal for hard-floor-heavy homes that don't need flagship suction.
Xiaomi priced the X20+ to kill. Under $450 gets you auto-empty, mop washing, air drying, water refill, and structured light obstacle avoidance — a feature set that cost $700+ just a year ago. The S-Cross avoidance is genuinely good at dodging shoes and chair legs. Mopping on hard floors is solid for daily maintenance with dual pads spinning at 180 RPM. The weakness is obvious: 6,000Pa suction and no hot water washing. Carpet owners will feel the gap immediately, and the cold-water mop rinse leaves something to be desired after a week of daily runs. This robot exists for one buyer profile: someone with mostly tile, hardwood, or laminate who wants full automation at the lowest possible price. It nails that brief.

Pros & Cons
What We Like
- + All-in-one dock with auto-empty, mop washing, air drying, and water refill at under $450
- + S-Cross structured light obstacle avoidance detects small objects with millimeter precision
- + Dual rotary mop pads at 180 RPM handle everyday hard floor stains and spills effectively
- + 140-minute battery life covers large homes up to 280 m² on a single charge
- + Automatic 7mm mop lift keeps carpets dry without needing manual pad removal
What Could Be Better
- − 6,000Pa suction is modest — 73% sand pickup on carpet trails most mid-range competitors
- − No hot water mop washing in the dock — pads get a room-temperature rinse only
- − Carpet detection requires manual setup in the app and occasionally misses low-pile rugs
