Does it really vacuum and wash at the same time?

Yes. In wet-dry mode it picks up debris while a wet roller scrubs the floor, then pulls dirty water into the tank. Dry debris and liquid go into the same recovery tank.

Can I use it on carpets?

Only for light pickup with the dry handheld or stick setup. The washing mode is for sealed hard floors, and it will not deep-clean rugs like a dedicated carpet cleaner.

How does it compare with the Tineco Floor One?

Both wash hard floors and self-clean. The Roborock adds a detachable handheld vacuum, which the Floor One does not offer, but Tineco models tend to have larger tanks and lighter handling.

What is included in the box?

The main wet-dry body, the detachable handheld vacuum, a roller brush, a filter and a charging and storage base. Extra brushes and filters are sold separately.

How long does the battery last?

Runtime depends on mode, but expect roughly half an hour of mixed cleaning per charge. Heavy suction and water flow shorten that, and a full charge takes a few hours.

Do I still need to clean the brush by hand?

The self-clean cycle does most of the work, but hair and debris still wrap the roller. Plan to rinse the roller and filter periodically for best results.
