Robot vacuums have evolved from novelty gadgets into genuinely useful home appliances. But with prices ranging from $200 to $2,000, choosing the right one matters. We spent three months testing to find the best.
Our testing process is rigorous: we run each vacuum through standardized debris tests on hardwood, carpet, and tile. We measure suction power, battery life, and navigation accuracy. We live with each model for at least two weeks to catch real-world issues that lab tests miss.
