3.1 Method of operation
The Hako Hamster 800 V/E is a
manu
ally operated Vacuum Sweeper
machine with a drive for the dry
cleaning of hard floors and carpets.
The side brush (Fig. 6/4), located on the
right-hand side of the machine, sweeps
the dirt away from corners and edges
into the path of the rotary brush
(Fig. 6/3). The rotary brush (Fig. 6/3)
sweeps the dirt into the two dirt hoppers
(Fig. 6/2) using the overhead throw
method. The particulate matter
(depicted gray in Fig. 6) is forced
against the panel air filter (Fig . 6/1) by
the suction turbine (Fig. 6/5) and filtered
out there. Only dust-free air is fed back
into the ambient air.
