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.
During our initial setup, the S-Cross structured light avoidance dodged a pair of sneakers and a USB cable on the first run -- no contact, no hesitation. 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. 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. This robot exists for one buyer profile: someone with mostly tile, hardwood, or laminate who wants full automation at the lowest possible price.

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
- + 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
