How to choose a robot vacuum: here’s what to look for

Robot vacuums are designed to save you time and effort when cleaning your home. With a wide range of features and price points, understanding what each model offers can be tricky. This guide unpacks the terminology and helps you navigate the options available.

Key Features to Consider

1. Suction Power

• Measurement: Suction is measured in pascals (Pa), indicating the air pressure the vacuum can create to lift dust and debris.
• Typical Ranges:
  • Premium Models: 10,000 Pa and above (e.g., Ecovacs Deebot T30S Combo)
  • Mid-Range: 5,000 – 7,000 Pa
  • Budget Models: Below 5,000 Pa
• Note: Suction power should not be the sole deciding factor; brush type and smart features also influence performance.

2. Mopping Functionality

• Many models now feature mopping capabilities, often using either semicircular pads that press down or rotating disc pads.
• Considerations:
  • Effectiveness is limited compared to manual mopping.
  • Look for models that can lift mop pads when transitioning from hard floors to carpets to avoid cross-contamination.

3. Robot Height and Clearance

• A lower-profile robot can clean under furniture more effectively.
• Most models cannot climb stairs, but many are equipped with cliff sensors to prevent falls.

4. Self-Cleaning and Self-Emptying Docks

• Self-Emptying: Automates the process of emptying the dustbin, ideal for pet owners.
• Maintenance Features: Some models can refill water tanks and even clean mop pads, reducing manual upkeep.

5. Edge Cleaning Features

• Round robots may struggle with corners; look for models with side brushes or unique designs that enhance edge cleaning.
• Be aware of models that use air blasts to collect dirt, though effectiveness can vary.

6. Object Avoidance and Navigation

• Lower-end models may randomly bump around, while advanced models map your home and can avoid obstacles.
• Features like room labeling and targeted cleaning add convenience.

7. Smart Features

• Most modern robot vacuums offer Wi-Fi connectivity and companion apps, allowing for remote control, scheduling, and monitoring.
• Some models are compatible with voice assistants for hands-free operation.

Pricing Categories

• Budget: Under $500 / £400
• Mid-Range: $400 – $800 / £400 – £650
• Premium: Over $800 / £650
• Note: Higher prices often correlate with advanced features like mopping, self-cleaning, and enhanced navigation capabilities.

Choosing the right robot vacuum involves considering your cleaning needs, home layout, and budget. While premium models offer advanced features, many mid-range options provide excellent cleaning capabilities without the hefty price tag. Remember to read reviews to determine if a specific model’s features perform as promised.
