HOW THE MACHINE WORKS
The B2 litter vacuum machine is designed to pick up and
shred debris. The vacuum system sucks the debris up
through the suction head and into the impeller, where the
debris is shredded, and then deposits the shredded
debris into the bag.

2. Check the battery meter (A) for charge level. Refer
to Fig. 5 for location of battery meter.
3. Turn off battery charger and disconnect the battery
charger cable from the machine.
4. Ensure the required bag(s) are empty and free of
damage or excessive wear.
