This scouring and vacuum machine is used for wet cleaning or polishing of level floors.

With the Combo variant, loose dirt is picked up by a sweeping mechanism before cleaning.

The device can be adjusted to suit the respective cleaning task by adjusting the water quantity, contact pressure, brush speed, detergent volume and travel speed.

A working width of 1000 mm or 1200 mm and a capacity of 260 l in the fresh and waste water tank each enable effective cleaning with long working times.

The device has a travel drive, the driving motor is powered by a traction battery. The batteries can be charged by means of a charger at a 230-V socket.

Battery and charger are already supplied with the package variants.

This device is suitable for commercial and industrial use, e.g. logistics halls, factories, industrial systems, car parks, trade fairs and retail premises. Use this device only in accordance with the information in these operating instructions.

• The device may only be used for cleaning floors that are insensitive to water and polishing.

• The device is designed for cleaning indoor floors or covered areas. For other application areas, the use of alternative brushes or the use of the sweeping mechanism must be checked.

• The operational temperature range is between +5 °C and +40 °C.

• The device is not suitable for cleaning frozen floors (e.g. in cold stores).

• With the Combo variant: The device may be driven over steps up to a maximum height of 2 cm.

• The device may not be operated without a lint filter in the waste water tank.

• The device is not intended for cleaning public traffic routes.
