How We Tested
Each robot vacuum was tested in the same 1,800 square foot test home with hardwood floors, medium-pile carpet, area rugs, and tile. We spread measured amounts of flour, rice, pet hair, and cereal to test pickup performance. Navigation was evaluated by observing coverage patterns and ability to avoid obstacles. Battery life and charging times were measured precisely. We lived with each robot for two weeks to assess real-world usability, app quality, and maintenance requirements.
Roborock S8 MaxV Ultra
The Roborock S8 MaxV Ultra represents the pinnacle of robot vacuum technology in 2025. Its 10,000 Pa suction power is the highest we've tested, pulling embedded dirt from carpet fibers that other vacuums miss. The dual rubber brush system prevents hair tangles—a game-changer for pet owners. The AI-powered camera recognizes and avoids over 70 object types, from cables to pet waste. The all-in-one dock empties the dustbin, washes and dries the mop pads, and refills the water tank automatically. After two weeks of testing, we barely had to touch it.
- Unmatched suction power at 10,000 Pa
- Excellent obstacle detection avoids cables, shoes, and pet waste
- Fully autonomous—dock handles emptying, mop washing, and drying
- Premium price is a significant investment
- Large dock requires dedicated floor space
Roborock Q Revo
The Roborock Q Revo brings premium features to a more accessible price point. At $699, it includes a self-emptying dock that also washes and dries the mop pads—features that cost $1,500+ from competitors. Suction power of 5,500 Pa handles most messes effectively, and the rotating mop pads scrub floors better than vibrating designs. It lacks the advanced AI obstacle detection of the S8 MaxV, but the standard LiDAR navigation is reliable. For most homes, the Q Revo delivers 80% of the performance at less than half the price.
- Outstanding value with all-in-one dock
- Effective rotating mop pads
- Reliable LiDAR navigation and mapping
- No AI camera for obstacle detection
- Lower suction than flagship models
Frequently Asked Questions
Yes, modern robot vacuums work well on low to medium-pile carpet. Look for models with at least 3,000 Pa suction and automatic carpet detection that boosts power. For high-pile or shag carpet, you may still need occasional manual vacuuming, as robot vacuums can struggle with very thick fibers.
For most users, yes. Self-emptying bases let the vacuum run daily without manual intervention for weeks at a time. This is particularly valuable for pet owners or those with allergies who don't want to handle dust and debris frequently. The extra $200-400 cost typically saves significant daily hassle.
