Roborock Q5 Max+ vs Roborock Q8 Max+

Full Robot Vacuums comparison in 2026

Data from Amazon and official Roborock site.
2026 verdict
Choose the Roborock Q8 Max+ if your floors are not always clear: it adds obstacle detection and a built-in mop with a 0.35L water tank, two things the Roborock Q5 Max+ leaves out or sells as an extra.

Everything else that matters for daily vacuuming is shared: LiDAR mapping with no-go zones, 5500Pa suction, 240 minutes of battery and a self-emptying dock with a 2.5L bin. The Roborock Q5 Max+ answers with a larger onboard dustbin, 770ml against 470ml, and it stays the simpler pick for a tidy home that only needs scheduled vacuuming, since its mop plate and water tank are optional and sold separately. Neither washes, dries or lifts its mop, and both work with Alexa, Google Home and Home Assistant but not Apple Home. Pick the Roborock Q8 Max+ for mixed floors and clutter, the Roborock Q5 Max+ for a vacuum-first routine.

What the differences mean

Obstacle detection

The Roborock Q8 Max+ actively detects obstacles, while the Roborock Q5 Max+ relies on its bumper and cliff sensors. In a home with charging cables, shoes or toys on the floor, the Q8 is the one less likely to end its run stuck.

Mopping

Mopping is built into the Roborock Q8 Max+, with a 0.35L tank. On the Roborock Q5 Max+ it needs a mop plate and a 0.18L tank sold separately. Neither washes, dries or lifts the mop, so both are light damp-mopping rather than a deep-clean system.

Onboard dustbin

The Roborock Q5 Max+ carries 770ml onboard against 470ml on the Roborock Q8 Max+, which means fewer trips to the dock in a pet-heavy home. Both docks hold 2.5L, so the difference only shows during a long clean.

Real-time tracking

The Roborock Q8 Max+ lists real-time tracking in the app so you can watch where it is cleaning. It is not documented for the Roborock Q5 Max+, which still maps rooms and takes schedules and no-go zones.

Suction, battery and noise

Both list 5500Pa suction, 240 minutes of battery and 67 dB, so cleaning power and noise do not separate them. Choose on navigation and mopping instead.

Which one to buy if

What owners say

Owners of both Roborock models talk most about pet hair. They describe waking up to clean hardwood and carpet after an overnight run and going weeks between manual emptying thanks to the dock. Both groups also mention reliability: some Roborock Q5 Max+ owners report failures soon after the one-year warranty ends, and a minority of Roborock Q8 Max+ owners describe fan or dustbin sensor errors after months of daily use. Roborock Q5 Max+ owners single out mapping precision and no-go zones, and note that it can get stuck on cords because it has no obstacle sensor and that mopping needs accessories bought separately. Roborock Q8 Max+ owners single out the obstacle avoidance as better than older bump-and-go robots, and call the mop inconsistent and streaky, with a tank that needs frequent refills in bigger homes.
