Things to Consider Before Buying a Robot Vacuum
On February 25, 2026 By newsroom Topic: Appliance Buyers Guide
If you’re in the market for a robot vacuum, here are key lessons and tips to help you make the best decision based on firsthand experiences:
1. Set Realistic Expectations
- Purpose: Robot vacuums are for maintenance cleaning, not deep cleaning.
- Prep Work: Start with a deep clean (DIY or professional service) before relying on a robot for upkeep.
2. Go for LIDAR Technology
- Why LIDAR? Laser mapping (LIDAR or LDS 3D scanning) ensures superior navigation and room mapping.
- Skip Roombas: Most Roombas lack LIDAR and rely on less efficient technologies.
3. Wi-Fi Considerations
- Connectivity: Robot vacuums generally use 2.4 GHz Wi-Fi for communication.
- Signal Check: Use a signal strength app to ensure at least 65% Wi-Fi strength in all areas the robot will clean.
- Wi-Fi Extenders: Some robots don’t play well with extenders, so check compatibility.
4. Availability of Replacement Parts
- Key Parts: Look for a brand that sells replacement parts like side brushes, main brushes, HEPA filters, foam, and mop pads.
- Avoid Brands Without Support: Example—Liectroux G7 doesn’t have readily available parts, making maintenance difficult.
5. Mopping Features
- Mop Maintenance: Clean the mop every two rooms to avoid spreading dirt around the house.
- Smart Mopping Robots: Consider newer models (e.g., Roborock Q Revo) that automatically return to the dock to wash the mop during cleaning cycles.
6. Zone and Room Cleaning Options
- Choose a model that allows you to clean specific zones, spots, or individual rooms for greater control and efficiency.
7. Save on Dust Bags
- Reusable Bags: Empty the dust bag instead of throwing it away to save money. Most can be reused for extended periods.
8. App Troubleshooting
- If the robot is unresponsive via the app, restart the app. This resolves most issues without requiring further action.
Additional Tips
- Maintenance: Regularly clean the robot’s sensors, brushes, and mop pads to maintain peak performance.
- High-Traffic Areas: Use no-go zones in the app to prevent the robot from getting stuck or damaged.
- Pet Hair: If you have pets, opt for models designed to handle fur, such as those with rubber brushes.
With these tips, you can confidently choose a robot vacuum that fits your needs and keeps your home effortlessly tidy!
