The Features That Actually Matter
Robot vacuum specs can be overwhelming. Brands throw around numbers like "18,000Pa suction" and "LiDAR 3.0" — but what actually makes a difference in your home? Let's cut through the marketing.
Navigation: LiDAR vs Camera vs Gyroscope
LiDAR (Best) Uses laser mapping to create precise floor plans. The robot knows exactly where it is, where it's been, and where it needs to go. - ✅ Most accurate navigation - ✅ Creates detailed home maps - ✅ Room-by-room scheduling - ✅ Works in complete darkness - All our recommended models use LiDAR
Camera-Based Uses an upward-facing camera to identify landmarks on your ceiling. - ⚠️ Less accurate than LiDAR - ⚠️ Struggles in low light - ⚠️ Cheaper but noticeable difference
Gyroscope/Random (Avoid) Entry-level robots that bounce around randomly. - ❌ Misses spots constantly - ❌ Takes 2-3x longer to clean - ❌ No room mapping or scheduling
Our verdict: Don't buy a robot vacuum without LiDAR in 2026. Even the budget Dreame D20 Plus ($399) includes it.
Suction Power: How Much Do You Need?
| Suction | Good For | Examples |
|---|---|---|
| 4000-6000Pa | Light daily cleaning, hard floors | Entry-level models |
| 7000-10000Pa | All floor types, pet hair | Roborock Qrevo L (7000Pa) |
| 10000Pa+ | Deep carpet cleaning, heavy pet hair | Dreame D20 Plus (8000Pa) |
| 15000Pa+ | Premium deep cleaning | Roborock Qrevo Curv (18,500Pa) |
Reality check: 7000Pa+ handles 95% of Australian homes. You only need 10,000Pa+ if you have thick carpet and multiple pets.
Mopping: Is It Worth It?
Short answer: Yes, but only with auto mop-lift.
Most modern robots include a mopping function, but the quality varies enormously:
Vibrating Mop Pad (Basic) - Scrubs lightly while the robot drives - Good for daily maintenance on tiles and hardwood - Won't handle dried stains
Rotating/Roller Mop (Premium) - Applies real pressure to the floor - Can handle light-to-medium stains - The Ecovacs X8 Pro Omni uses this system
Auto Mop-Lift (Essential) This is the critical feature. When the robot detects carpet, it **lifts the mop pad** so it doesn't make your carpets soggy. - Available on Dreame D20 Plus, Roborock Qrevo L, and all premium models - **Don't buy a mopping robot without this** if you have any carpet
Hot Water Mop Washing Premium docks wash the mop with hot water and dry it with hot air after cleaning. This prevents mould and keeps the mop fresh — particularly important in Australia's humid coastal climates. - Available on Roborock Qrevo L and Qrevo Curv
Self-Emptying: A Game-Changer
Self-emptying docks collect dust from the robot's dustbin into a larger bag. You only empty the bag every 1-2 months.
Is it worth it? Absolutely. It's the single biggest quality-of-life upgrade in robot vacuums. All four robots on our best robot vacuums list include self-emptying.
Obstacle Avoidance
If you have kids or pets, obstacle avoidance matters:
- Basic: Bump-and-redirect. The robot hits things, then turns away.
- Camera AI: Recognises objects (shoes, cables, toys) and avoids them. Available on Roborock Qrevo L and above.
- 3D structured light: Most accurate avoidance. Premium models only.
What to Budget
| Budget | What You Get | Our Pick |
|---|---|---|
| $300-$500 | LiDAR, auto-empty, basic mop | Dreame D20 Plus ($399) |
| $500-$800 | All above + AI obstacle avoidance, hot water mop wash | Roborock Qrevo L ($649) |
| $800-$1500 | All above + premium suction, advanced mopping | Ecovacs X8 Pro Omni |
| $1500+ | Everything maxed out | Roborock Qrevo Curv |
Features You Can Skip
- UV sterilisation — Marketing gimmick. The UV exposure time is too short to sterilise anything
- Air freshener modules — Just makes your dustbin smell nice, doesn't clean better
- "Pet mode" — Usually just higher suction, which you can set manually
Australian-Specific Considerations
- Tile floors are very common in Australian homes. Mopping capability is more valuable here than in carpeted markets
- Open-plan living means larger cleaning areas. Budget 200+ minute battery life
- Pet ownership is high in Australia. Rubber brush rolls reduce hair tangles
- Humidity in coastal areas makes hot-water mop washing valuable to prevent mould
