The previous-gen benchmark with unique dock features - excellent but only worth buying at its now-common $899-$999 sale price.
A year ago, the S8 MaxV Ultra was the robot to beat. Today it is the robot to buy on sale. The auto detergent dispenser remains unique — no other robot adds cleaning solution to its mop wash automatically — and the optional plumbed Refill & Drainage System is still the gold standard for truly zero-maintenance operation. The RGB camera and VibraRise 3.0 with 20mm lift hold up well. What does not hold up is 10,000Pa suction at any price above $500 in 2026. Newer mid-range robots match or exceed it for half the cost. At its $1,799 MSRP, the S8 MaxV Ultra is a terrible buy. At $899 on sale, which happens frequently now, it becomes a smart pickup for buyers who want the plumbed dock option and do not care about chasing suction numbers.
