Roborock Q7 Plus

Let’s be direct: the Roborock Q7 Plus is a discontinued robot vacuum that probably isn’t worth buying in 2025. That said, if you’ve stumbled across a refurbished unit for $300-$350, or you’re trying to decide whether to repair your existing Q7 Plus, you’ll want the full picture.

The “Plus” branding simply means it ships with the RockDock auto-empty base. Strip that away, and you’ve got the standard Q7. Roborock released both variants in early 2021 as the inaugural entries in their mid-range Q-series lineup.

The Bottom Line on Performance

Here’s what the Q7 Plus does well: LiDAR navigation. The PreciSense system maps your home methodically, building multi-floor layouts and executing systematic cleaning patterns. Navigation testing scores clock in around 0.83, comfortably above the 0.70 average. Your floors get covered efficiently, with minimal missed spots unless you’re living in a particularly cluttered space.

What it doesn’t do well: almost everything else by 2025 standards.

Pet hair removal? The single rubber brush scatters more than it picks up. Dark carpets? The cliff sensors mistake them for ledges and refuse to clean them entirely. Mopping? A passive drag pad that dampens surfaces but can’t actually scrub stains. Obstacle avoidance? Nonexistent, meaning cables get tangled, chair legs cause jams, and pet accidents get spread around if encountered.

Hardware Breakdown

At 2700 Pa of suction power, the Q7 Plus was middle-of-the-pack in 2021. Today’s Q7 M5 delivers 10,000 Pa at a similar price point. That’s a 3.7x improvement in just four years.

The 750ml dustbin handles debris reasonably well, while the 180ml water tank for mopping runs dry mid-session in larger homes. Battery life impresses: 180 minutes officially, with real-world testing showing up to 240 minutes in Quiet mode. Expect to cover roughly 1,060 to 1,900 square feet on a single charge, depending on your suction settings.

At 3.9 inches tall, the robot clears most furniture. The 20mm threshold climbing capability handles standard floor transitions, though some owners report occasional slipping on metal transition strips.

The Auto-Empty Dock

The RockDock Pure that comes bundled with the Plus variant handles dust extraction automatically after each cleaning cycle. A 2.5L bagged system holds roughly seven weeks of debris for an average household. Bags seal during disposal, keeping dust contained.

No mop washing, no mop drying, no water tank refills from the dock. You’re handling the mopping side of maintenance manually.

App and Smart Features

Roborock’s app earns solid ratings: 4.8 stars on iOS, 4.6 on Google Play. Setup takes 10-15 minutes, and you’ll get access to 3D mapping, multi-floor support (up to four maps), no-go zones, room-specific scheduling, and the usual suite of cleaning customizations.

Voice control works through Alexa, Google Assistant, and Siri Shortcuts. No Matter or HomeKit support, and the robot requires 2.4 GHz WiFi only.

The app’s reliability draws complaints, though. Users report needing to re-pair their vacuum every two to four weeks due to WiFi connection drops. A 12-character password limit also raises eyebrows for security-conscious owners.

Cleaning Performance Reality Check

Hard floors: The Q7 Plus handles hardwood, tile, and vinyl competently. Surface debris disappears, and suction adjustments let you dial in power for different situations.

Low-pile carpet: Adequate for surface debris, but fine particles embedded in fibers stay put.

Medium to high-pile carpet: Better results here, with the brushroll penetrating softer surfaces more effectively.

Pet hair: Not recommended. The single rubber brush design simply can’t compete with dual-brush competitors.

Mopping: Think light maintenance between real mopping sessions, not a replacement for actual floor cleaning.

Known Issues Worth Noting

The black carpet problem frustrates owners with dark rugs. Cliff sensors interpret the dark color as a drop-off and refuse to cross. Workarounds exist (covering sensors with tape, setting virtual walls), but they shouldn’t be necessary.

Without obstacle avoidance cameras, the Q7 Plus relies on bumpers alone. Chair legs, cables, rug fringes, and anything else in its path become potential snag points. One or two stuck incidents per five to ten cleaning cycles seems typical for moderately cluttered homes.

Some dock units fail to auto-empty consistently. WiFi drops require frequent app reconnection. The mopping pad leaves streaks rather than clean floors. These complaints surface regularly across Reddit communities and product reviews.

Maintenance and Costs

Replacement parts remain readily available through Roborock and Amazon. Expect to spend $80-$150 annually on filters, brushes, side brushes, and dust bags. Battery replacements run $150-$200 after two to three years.

The rubber brush resists hair tangling better than bristle alternatives, making cleanup easier. The washable E11 HEPA filter needs a 24-hour dry time after washing.

Warranty coverage lasts one year for manufacturing defects. Support responsiveness varies significantly, and some owners report difficulty getting warranty claims honored.

Who Should Consider This Vacuum

Potentially worth buying if:

• You find a refurbished unit for $300-$350
• Your home is under 1,000 square feet with hard floors
• You don’t have pets or dark carpets
• You’re already invested in Roborock’s ecosystem

Skip it if:

• You have pets (poor hair pickup)
• You own dark-colored carpets or rugs (cliff sensor false positives)
• You expect the mop to actually clean stains
• Your home has lots of obstacles (no avoidance capability)
• You’re shopping new (the Q7 M5 or Q5 Pro offer far better value)

The Competitive Picture

At its original $599-$699 launch price, the Q7 Plus competed reasonably well. Four years later, the math doesn’t work. Roborock’s own Q7 M5 delivers 3.7 times the suction at equivalent or lower pricing. The Q5 Pro adds dual brushes for better pet hair handling at $139-$249.

The Q7 Plus makes sense today only as a discounted purchase or if you’re evaluating whether to keep an existing unit running.
