Roborock Q7 M5+ vs Shark Navigator RV2120AE: Which One Is Better for You?
Choose based on cleaning scope and dock consumables: the Q7 M5+ is the feature-fit pick when you want vacuuming plus adjustable mopping and accept a bagged dock; the RV2120AE fits vacuum-only homes that prefer a bagless self-empty base. Official specifications do not establish a suction, coverage, or obstacle-avoidance winner.

The buying question
Which cleaning system and dock-maintenance tradeoff better matches this home's needs?
The Q7 M5+ provides documented vacuum-and-mop capability but adds wet-component care and dust bags; the RV2120AE removes mopping and uses a bagless base, so the choice is feature fit rather than a proven cleaning-performance ranking.

The differences that matter
cleaning system
roborock Q7 M5+ Robot Vacuum and Mop, Up to 7-9 Weeks Self-Empty, 10000Pa: Vacuum-and-mop robot; official sources list three adjustable water-flow levels and a detachable mop module.
Shark Navigator Robot Vacuum + Self-Empty Base, Grey, RV2120AE: Vacuum-only Navigator; Shark's exact RV2120AE page lists no mop and documents a self-cleaning brushroll.
A buyer who needs wet cleaning gets a clear feature-fit advantage from A; a vacuum-only buyer does not need to pay for or maintain that added system.
dock automation
roborock Q7 M5+ Robot Vacuum and Mop, Up to 7-9 Weeks Self-Empty, 10000Pa: RockDock Plus uses a sealed 2.7 L dust bag; Roborock publishes up to 7–9 weeks under its stated conditions.
Shark Navigator Robot Vacuum + Self-Empty Base, Grey, RV2120AE: Self-empty base is bagless and Shark publishes up to 60 days of debris storage under its stated conditions.
A favors buyers who prefer a sealed bag system; B favors buyers who want to avoid disposable bags. The different manufacturer time estimates are not directly comparable and do not decide the winner.
maintenance
roborock Q7 M5+ Robot Vacuum and Mop, Up to 7-9 Weeks Self-Empty, 10000Pa: The Q7 Series manual instructs users to replace the dust bag when full, clean the dock filter, clean the washable filter every two weeks, wash and air-dry the mop, and empty the water tank after mopping; it gives 3–6 month dock-filter and 6–12 month washable-filter replacement guidance.
Shark Navigator Robot Vacuum + Self-Empty Base, Grey, RV2120AE: The exact RV2120AE page documents a bagless self-empty base and self-cleaning brushroll, but does not provide an equivalent filter/brush replacement schedule on the opened product page.
A's care tasks are more explicitly documented and include wet-mop upkeep and bag replacement; B avoids bags but its detailed recurring care schedule remains to be verified, so neither side earns a blanket low-maintenance verdict.
navigation
roborock Q7 M5+ Robot Vacuum and Mop, Up to 7-9 Weeks Self-Empty, 10000Pa: PreciSense LiDAR mapping; Roborock describes multi-floor maps and smart no-go-zone suggestions for the Q7 series.
Shark Navigator Robot Vacuum + Self-Empty Base, Grey, RV2120AE: SmartPath row-by-row cleaning with spot LiDAR and published object detection/avoidance.
The documented feature sets may suit different layouts, but official descriptions alone do not show which robot navigates or avoids obstacles better in a home.
suction
roborock Q7 M5+ Robot Vacuum and Mop, Up to 7-9 Weeks Self-Empty, 10000Pa: Roborock publishes 10,000 Pa for Q7 M5+.
Shark Navigator Robot Vacuum + Self-Empty Base, Grey, RV2120AE: Shark publishes up to 50% more suction versus iRobot Combo Essential, a different comparison reference rather than a measurement against Q7 M5+.
These manufacturer figures use different baselines and do not support a direct suction ranking between A and B.
Choose for your routine
Homes that require automated mopping as well as vacuuming
Only A is documented as a vacuum-and-mop robot with adjustable water flow and a detachable mop module.
Vacuum-only homes that want to avoid disposable dust bags
B is documented as vacuum-only and its self-empty base is bagless; this is a feature-fit choice, not a claim of better cleaning performance.
Buyer balancing mopping and wet-component care plus dust bags against vacuum-only cleaning and a bagless base
Choose A when mopping is required and washing the mop, emptying/cleaning water tanks, and replacing a dust bag are acceptable; choose B when vacuum-only cleaning is sufficient and a bagless base is preferable. Neither side is labeled the overall lower-maintenance product.
Value and trade-offs
Compare live prices and total ownership costs, including Roborock dust bags and mop-care consumables, against Shark's bagless-base convenience. Neither product's list price or manufacturer day estimate proves superior value.
The available price history is short and recent, with current observations but no reliable long-run baseline; avoid a definite Buy Now or Wait call.
Limitations
- This is an official-source research draft; no hands-on testing was performed.
- No bilateral E2/E3 measurements support a suction, coverage, navigation, obstacle-avoidance, noise, or reliability winner.
- Roborock's 7–9-week and Shark's 60-day dock figures are different manufacturer estimates and are not a direct durability or ownership comparison.
- Shark's exact RV2120AE product page confirms bagless emptying and a self-cleaning brushroll but does not expose an equivalent detailed filter/brush maintenance schedule.
- The exact Shark official page identifies Model RV2120AE; detailed replacement intervals for its base, brushroll and filters are not established by the opened sources, so no overall maintenance superiority is claimed.
- Prices are dynamic observations over a short window, not an all-time-low analysis. No community owner evidence is included; any owner-experience claim would require separate verified research.
Does the Roborock Q7 M5+ mop while it vacuums?
Yes. Roborock's Q7 M5+ materials describe simultaneous vacuuming and mopping, three adjustable water-flow levels, and a detachable mop module.
Which robot uses a bagless self-empty base?
The Shark Navigator RV2120AE. Its exact official product page identifies the model and describes a bagless self-empty base; the Q7 M5+ uses a sealed dust bag.
Does Shark's 'up to 50% more suction' claim prove it beats the Q7 M5+?
No. Shark's claim is versus iRobot Combo Essential, while Roborock publishes 10,000 Pa; the different baselines do not establish a direct A-versus-B result.
Methodology and sources
Compared only decision-relevant cleaning-system, dock, maintenance, navigation, suction and price evidence, keeping manufacturer claims separate from bilateral performance evidence.
Automation assisted source extraction, identity cross-checking, price-history/GSC reads, and deterministic schema checks; it did not perform product testing.
