What the Max 875 Combo Adds
The Roomba Max 875 Combo adds 35,000 Pa suction and 20 L/s airflow with active SealForce chassis sealing. iRobot says this configuration provides 3x deeper carpet cleaning. The chassis measures 9.98 cm tall and climbs thresholds up to 3.5 cm.
The mopping system upgrades to the PowerSpin Max roller mop. It runs at 300 RPM with 18 N of downward pressure. iRobot states this roller is 44 percent larger. It features ultrasonic ThermaMist heated mist and a DriLift AI roller shield.
Edge cleaning uses a PerfectEdge mechanism that extends the roller up to 45 mm. Navigation runs on ClearView Pro dual-line LiDAR. For obstacle avoidance, PrecisionVision AI identifies more than 300 household objects. The robot uses a 5000 mAh NCM battery.
What the Max 775 Combo Offers
The Roomba Max 775 Combo features a PowerSpin roller mop operating at 200 RPM. It uses SmartScrub back-and-forth movement and heated spot mopping. The roller cover lifts and shields on carpet, and the roller uses PerfectEdge.
Suction is listed as a relative claim of 4X more power-lifting suction. iRobot has published no Pascal rating for the Max 775 Combo on its product page. ClearView Pro LiDAR handles navigation and saves up to 5 maps.
PrecisionVision AI avoids obstacles including cords, shoes, and pet waste. The Max 775 Combo carries a 6000 mAh LFP battery. See also our Roomba j series page.
The AutoWash Dock Compared
Both models ship with an AutoWash dock that washes roller mops and empties dust. The Max 775 AutoWash dock washes with 75 C (165 F) self-clean water and dries with 50 C (122 F) air. It dispenses StayClean concentrate automatically.
The Max 775 dock measures 17.7 by 16.7 by 17 inches and weighs 18.96 lb. Its carbon odor-control bag holds debris for up to 3 months. The Max 875 AutoWash dock washes at 176 F and dries with 131 F heated air.
The Max 875 dock bag holds debris for up to 90 days. It also auto-dispenses StayClean cleaning concentrate.
Hardware Specifications and Feature Comparison
Comparing published manufacturer metrics highlights the mechanical differences across both machines. The Max 875 Combo provides explicit Pascal ratings, higher roller rotation speeds, and hotter dock temperatures. The Max 775 Combo relies on a relative suction claim but includes a larger battery capacity.

Which Model to Buy
Buyers who require stated pressure figures should choose the Max 875 Combo. Its 35,000 Pa rating, 300 RPM roller, and 18 N downforce provide documented power metrics. It also clears 3.5 cm thresholds and avoids 300+ listed objects.
Buyers seeking lower initial costs can select the Max 775 Combo at $999.99 at the time of writing. It retains the self-emptying dock, 75 C wash water, and a 6000 mAh LFP battery. Those considering other brands can compare details in our Roomba vs Eufy guide.
The Max 775 Combo is not for shoppers who demand published Pascal suction ratings. The Max 875 Combo is not for buyers who want the lower price of the 775.
Final Procurement Verdict
The Roomba Max 775 Combo and Max 875 Combo are both listed by iRobot as roller mop combos. Choosing between them comes down to the $200 price spread and specific cleaning components. The Max 875 adds active SealForce suction, ThermaMist spray, and hotter dock cycles.
Our verdict would flip if iRobot published an equivalent suction rating for the 775 or reduced the pricing gap. Shoppers should check current terms directly on the maker's site before buying.
Bottom Line
The Roomba Max 875 Combo delivers documented suction at 35,000 Pa, faster 300 RPM roller rotation, and higher dock wash temperatures for a $200 premium. The Max 775 Combo at $999.99 at the time of writing offers an AutoWash dock, 75 C washing, and a 6000 mAh LFP battery without a published Pascal rating. If iRobot publishes a Pascal rating for the Max 775, this comparison would change.
