ECOVACS’ flagship roller-mop robot is $300 off right now. The DEEBOT T90 PRO Omni is down to $499 at Amazon, reduced from its $799.99 list price — a 38% discount on a premium vacuum-and-mop with 30,000Pa suction and an OMNI station that washes its own mop.
The deal
- Sale price: $499.00
- List price: $799.99
- You save: $300.99 (38% off)
- Where: Amazon — price verified live on the product page; the $300-off promotion runs through October 5
Why it’s a good buy
- 30,000Pa BLAST suction — among the strongest in any robot vacuum — paired with ZeroTangle 4.0 to keep pet hair from wrapping the brush.
- OZMO Roller 3.0 actually scrubs: a 10.6-inch self-washing roller with pressurized, continuous scrubbing instead of dragging a damp pad, with hot-water wash and 145°F hot-air drying at the dock.
- TruEdge 3.0 extends the roller past the body to clean baseboards and corners, and the roller lifts 0.6 inches to keep carpets dry.
- 200-minute battery, AI obstacle avoidance, and an OMNI station that handles dust collection plus mop washing and drying.
Roller-mop flagships rarely dip to $499. If you’ve been waiting for premium mopping performance without the $800+ price tag, this is the window — but note the promotion ends October 5.
