Buying guide
Key factors to consider
Navigation is the primary difference between a robot that covers your floor systematically and one that wanders aimlessly. LiDAR-based models map your home with high precision, significantly reducing cleaning times and avoiding missed spots.
Suction power, measured in Pascals (Pa), determines the ability to remove debris from carpets. If you have pets, look for models exceeding 3000 Pa to effectively handle hair and dander.
Battery life must match your home's square footage. A 120-minute runtime is usually sufficient for apartments up to 100 sqm, but check if the unit features automatic resume after recharging.
Mistakes to avoid
- Buying a non-mapping model for a multi-room home: you will end up with uncleaned areas.
- Ignoring the robot's clearance height: ensure it fits under your furniture to reach dust where it hides.
- Assuming integrated mopping replaces manual scrubbing: most robots in this range provide a light surface wipe rather than a deep clean.
- Overlooking replacement part availability: filters and brushes require replacement every 6 months, verify their online availability.
Frequently asked questions
Do I really need maximum suction?
Not necessarily. Hard floors only require about 2000 Pa, whereas thick carpets need more power to pull debris from deep within the fibers.
Can I operate the vacuum without an app?
Many models include remote controls or physical buttons, but you would lose advanced features like scheduling and no-go zones.
Is laser mapping superior to gyroscopic?
Yes, LiDAR technology scans your room with millimeter precision even in total darkness, resulting in a much faster and efficient path.
