$58 under your budget
The cheapest self-emptying robot our 8 sources rank - 300 minutes of runtime, 8,000Pa, and a bagless base with no refill bags to keep buying.
Fit ledger — need → measured evidence
■ The catch — co-equal billing, always
The mopping is a passive drag pad. No water flow, no sonic scrubbing, no pad washing - it wipes crumbs and dust and is useless on anything dried or ground in. Buy it as a vacuum that dusts the floor on its way past, not as a mop.

Traps — this verdict avoids
Why the ECOVACS DEEBOT N20 Plus is right for you
It avoids every trap below — and for family of 4, under $250, it is the pick because it delivers:
Pascal inflation
Sub-$300 suction jumped from 2,000-4,000Pa in 2023 to 5,000-10,000Pa in 2026, but Pa is manufacturer-reported with no standardized test across brands. Above 8,000Pa the real-world gain on hard floors is modest; airflow and brush design decide actual cleaning.
The Roomba reflex
The brand most people type has left the band: the Roomba 694 has drifted to ~$330, above this cap, for ~1,700Pa, gyro-only navigation and no mapping. iRobot was also sold to Picea Robotics on January 23, 2026, and review outlets now advise caution on new Roomba purchases.
Mopping is a drag pad
Only two models under $300 move water at all - the Q10 S5+ and the Tapo RV30 Max Plus. The rest drag a passive damp pad that is ineffective on dried stains, and no model at this price has a hot-water mop-washing dock.
