The unit is offered in white and black colour options.

Size and Practical Fit

Uses and Placement

This robot is intended for household floor cleaning where suction, sweeping and mopping are needed in one pass. It can be used in larger rooms and open areas within the stated 90-120 square metre range. Remote control operation means you can start it without being next to the unit.

Event or Professional Use

The source describes this as an intelligent household sweeping robot, so its stated use is domestic floor cleaning. It is not presented as a commercial or industrial machine. The 300ml capacity and 61-120 minute battery life are the main working limits given. For spaces within the applicable area, it can be used as part of a regular cleaning routine.

Everyday Home Use

For everyday home use, the three-in-one action reduces the need to switch between separate suction, sweeping and mopping tools. The remote control allows operation from a distance. The 300ml capacity means the collected material is held in the unit until emptied. USB charging keeps the power method familiar and straightforward.

Benefits and Buying Value

Reuse and Low Maintenance

The robot is rechargeable via USB, so it can be used repeatedly after charging. Emptying the 300ml capacity is the main routine task described by the available data. The source does not include filter details, so no further maintenance guidance is given here. Keeping the unit dry and storing it when not in use is consistent with its electrical design.
