iRobot Roomba Max 775 Combo Review: Great Mopping, Buggy App

As an Amazon Associate I earn from qualifying purchases. Disclosure

Overview

The Roomba Max 775 Combo is iRobot’s 2026 roller-mop robot: one machine that vacuums, mops with a self-washing roller, and hands its dirt, dirty water and drying off to a tall AutoWash dock. It is for homes with a good amount of hard flooring and some rugs, where the owner wants mopping to happen without rinsing pads or carrying buckets.

It replaces last year’s Max 705 Combo, and iRobot’s list of changes is mostly inside the machine and dock: more suction, heated spot mopping, better recognition of pet-related objects, carbon odor-control dust bags, a hotter 75°C (167°F) roller wash and up to three months between bag changes. On the outside the two look almost the same: Gizmodo found the 775 nearly identical out of the box, down to the roller brushes. Amazon.ca sells the same model number (X285020) as the US store, and iRobot Canada backs it with a one-year limited warranty. As of October 2026, one full independent test of the 775 has been published, Gizmodo’s, so this review leans on that test and on iRobot’s own specifications.

Key Specifications

iRobot Roomba Max 775 Combo Mopping and Rug Protection

Mopping is the 775’s strongest suit. Its roller spins at 200 RPM and is rinsed with heated water and scraped while the robot works, which iRobot says helps stop dirty water and grime being spread around the house, and it slides out toward walls, furniture and corners. That shows on spills: Gizmodo’s usual ketchup test went as well for the 775 as for the Matic and the Ecovacs Deebot X12 OmniCyclone, the best roller-mop robots it had compared, and the floors came out streak-free up to the baseboards.

The carpet guard is the other half of the design. When the robot detects a rug, a cover lifts over the roller, which iRobot says helps avoid wet carpets, and iRobot told Gizmodo the detection comes from an ultrasonic sensor underneath. It isn’t perfect on every surface: Gizmodo’s tester caught the 775 mopping a small patch of a thin bedroom rug next to a clear chair mat, and iRobot suggested the very low pile and the clear mat, which the sensor may have read as hard floor, could be the cause. A no-mop zone drawn in the app fixed it, so anyone with thin rugs or clear mats should plan to draw one on day one.

Vacuuming, Navigation and Obstacles

Vacuuming is solid rather than standout. Over Gizmodo’s testing, everyday pickup was dependable on both hard floors and rugs, and the bin never clogged. The robot runs dual rubber brushes, which iRobot says resist tangling from pet and long hair, plus two edge-sweeping brushes; the outlet’s testing didn’t report hair results either way.

Navigation is gentle and methodical. The LiDAR map of Gizmodo’s 70 m² (750-square-foot) apartment took about 11 minutes and split most rooms correctly on its own, and the robot worked around ornate table bases without ramming furniture. A tidy floor matters more than iRobot’s object recognition suggests: iRobot says it recognizes cords, shoes and pet waste, but the robot wedged itself under a child’s bed in Gizmodo’s test, and cords were its other weak spot: none got wound into a brush, but two ended up under the chassis, one of them after the robot had steered around it more than once. Picking up cables and small items before a run is the practical fix.

Dock, Battery and Upkeep

The AutoWash dock takes the bin, pad and roller-washing chores off your hands. After each run it empties the robot into a carbon odor-control bag that iRobot rates for up to three months, washes the roller with hot water, dries it with heated air and refills the robot with water mixed with StayClean concentrate. The box includes a spare bag, so two bags cover up to about six months of emptying before you buy more. Routine care is still yours: iRobot asks owners to wipe the robot’s bin, rinse the dock’s tanks, clean the charging contacts and brushes, and change the filter every three to six months.

One charge covered a whole small apartment in testing. Gizmodo sent the 775 to vacuum and then mop its whole 70 m² (750-square-foot) apartment, and it came back after two and a half hours with 36% left, about the same reserve as the Roborock Qrevo 2 Pro, which finished the same job faster.

App and Noise

The Roomba Home app is simple to find your way around, with suction and mopping levels, no-go and no-mop zones and a choice of how often the dock empties. Its weak spot is long runs: in Gizmodo’s test the app regularly lost track of the robot during whole-home cleans, the map wouldn’t reload until the robot docked, and the robot could only be controlled from its own buttons in the meantime. Push alerts also opened the app without saying what had gone wrong. iRobot told the outlet it is rolling out updates to improve connectivity and syncing, so this may change, but buyers today should expect it.

It is a loud robot. Gizmodo’s tester found the high-pitched whine during cleaning annoying, and the dock is loud enough to interrupt a conversation while it empties the bin. Scheduling it for when nobody is home avoids both, and its voice prompts can be turned down to silent.

How Does It Stack Up Against the Competition?

Two of these use a self-washing roller like the 775; the Roborock uses spinning pads instead. Specs are each maker’s figures, except the Roborock’s dock details, which are from Tom’s Guide’s review. The Dreame’s wash temperature and bag life are from Vacuum Wars’ review.

The Ecovacs and Dreame are the closest matches: both use a self-washing roller with a carpet cover or guard, and the Dreame matches the 775’s suction rating, with a retracting LiDAR turret that lets it drop to 9.8 cm (3.84 in) for low furniture (12.0 cm, 4.72 in, raised). The Ecovacs empties into a bagless bin you dump yourself rather than a bag you replace, which some owners will prefer. The Roborock takes a different approach to rugs, detaching its mop pads automatically for carpet rather than covering a roller, and in Gizmodo’s battery comparison it finished a whole-home vacuum-and-mop run faster than the 775.

iRobot Roomba Max 775 Combo: Worth It When Mopping Matters Most

Buy the 775 if your floors are mostly tile, wood or vinyl with a few rugs, and you want the mopping handled properly without touching a pad or a bucket. The hot-washed roller, the rug cover and up to three months between bag changes take most mopping chores off your hands. Gizmodo’s verdict is cooler: it found the 775 hard to tell apart from the many similar robots from Roborock, Dreame, Ecovacs and Eufy, and still needed some supervision, so expect to tidy cables and check on long runs. On Amazon.ca in October 2026 it cost $1,299.99 CAD against $1,207.89 CAD for the Dreame Aqua10 Ultra Roller; the table above shows how their specs compare. Schedule it for when you’re out, because both the robot and the dock are loud, and plan a no-mop zone for any thin rug or clear chair mat.

If you’d rather the mop come off entirely before carpet, the Roborock Qrevo 2 Pro detaches its spinning pads automatically. If you want to compare other roller mops, start with the Dreame Aqua10 Ultra Roller and Ecovacs Deebot X12 OmniCyclone in the table above. Owners of last year’s Max 705 Combo have little reason to switch: Gizmodo found the two almost identical to look at, down to the roller brushes, and iRobot’s changes are incremental: heated spot mopping, better pet-object recognition, anti-tangle brushes, and a dock with odor-control bags, a hotter wash and longer between bag changes.
