## Long description

UMAX UB911 is a bagless robot vacuum designed for everyday floor maintenance on hard floors and low‑pile carpets.

Advantages
The UMAX UB911 combines vacuuming and wet mopping in a single, bagless design that reduces the need for disposable accessories. Its large-capacity lithium‑ion battery provides extended cleaning sessions without frequent recharging, and the automatic return-to-base feature ensures convenient charging after a cleaning cycle. The compact footprint and relatively low weight make placement and handling easier, while the moderate noise level supports operation during daytime use in living spaces.

How to use
Place the UMAX UB911 on a level surface and ensure the charging base is positioned against a wall with clear space around it. Charge the device fully before first use. Select the appropriate cleaning mode to enable vacuuming, wet mopping, or a combination of both according to the floor type. Remove obstacles such as loose cables and small objects from the floor area to allow uninterrupted cleaning cycles. After a cycle completes, the robot will automatically return to the base to recharge; empty the dust container and refill or replace the mopping pad as needed to maintain cleaning performance.
Usage recommendations
For best results, sweep or pick up large debris before starting the robot, use the wet mopping function on sealed hard floors only, and perform regular maintenance: empty the dust container after each use, wash the mopping pad according to the manufacturer’s instructions, and keep sensors and charging contacts clean to ensure reliable automatic return and optimal runtime.
