Ultenic Ultenic T20 Pro

How often do I need to empty the self-emptying station?

The 3.5-litre base station typically needs emptying every 2-4 weeks depending on your home size and cleaning frequency. The station uses disposable bags that you simply lift out and replace. The robot automatically empties its internal dustbin after each cleaning session, so you rarely need to touch the robot itself.

Can the T20 Pro clean both carpets and hard floors effectively?

Yes, the robot automatically detects carpet surfaces and boosts suction power for deeper cleaning. The 8000Pa suction handles embedded pet hair and debris in carpets, whilst the adjustable water flow system allows gentle mopping of hard floors. You can set no-mop zones to protect rugs and carpets from water damage.

How accurate is the mapping and navigation system?

The LiDAR laser navigation creates precise room maps during the first cleaning cycle, typically taking 30-45 minutes for an average home. The system accurately identifies furniture, walls and obstacles, allowing you to divide your home into specific rooms and create custom cleaning schedules for each area.

What happens if the robot gets stuck or encounters an error?

The T20 Pro features a triple safety system with anti-drop sensors, anti-tangle torque control and anti-collision laser scanning. If the robot does encounter an issue, it emits beeping sounds and sends error notifications through the app, then attempts to return to its charging station rather than forcing through and potentially causing damage.

How long does the battery last and how long does charging take?

The battery provides 180 minutes of continuous cleaning, sufficient for homes up to 200 square metres. Charging takes approximately 3-4 hours from empty to full. The robot automatically returns to charge when battery drops below 15% and resumes cleaning from where it stopped once recharged.

Can I control the robot when I'm not at home?

Yes, the WiFi-connected robot can be controlled remotely through the smartphone app from anywhere. You can start cleaning sessions, check progress, receive notifications and modify schedules whilst away from home. The app also provides real-time status updates and cleaning history.

How quiet is the T20 Pro during operation?

The robot operates at 60dB, which is quieter than most traditional vacuum cleaners but not silent. This noise level allows for daytime cleaning without significantly disrupting conversations, work calls, or television viewing, though you will still hear it running in the same room.

What maintenance is required for optimal performance?

Regular maintenance includes washing the reusable filters monthly, replacing the mop pad when worn and cleaning the main brush to prevent hair tangles. The robot comes with spare filters, brushes and mop pads. The self-emptying station requires only periodic bag replacement and occasional sensor cleaning with a dry cloth.
