1. A canister vacuum arrangement, comprising:
- a) a cart having a front end and a rear end, the cart including wheels for transport of the canister vacuum arrangement;
b) a blower motor mounted adjacent to one of the front and rear ends of the cart, the blower motor including an inlet and an outlet;
c) a canister housing mounted adjacent to the other of the front and rear ends of the cart, the canister housing including a canister inlet and a canister outlet, the outlet of the blower motor being interconnected to the canister inlet, the canister housing including;
i) a cylindrical separation chamber;
ii) a particulate collection region located beneath the separation chamber; and
iii) a filter chamber located above the separation chamber, the filter chamber and the separation chamber defining the canister outlet therebetween; and
d) a removable filter positioned within the filter chamber of the canister housing, the filter chamber having an inlet side and an outlet side;
e) wherein airflow generated by the blower motor enters the canister housing at the cylindrical separation chamber, flows through the filter, and exits the canister housing through the canister outlet.

Abstract
A canister vacuum arrangement including a canister vacuum carried by a cart. The canister vacuum including a blower motor and a canister housing. The canister housing includes a separation chamber, a particulate collection region located beneath the separation chamber, and a filter chamber located above the separation chamber. A removable filter is positioned within the filter chamber. In operation, airflow generated by the blower motor enters that canister housing at the separation chamber, flows through the filter, and exits the canister housing through an annular outlet defined between the separation chamber and the filter chamber.

20. A method of using a canister vacuum arrangement, the method comprising the steps of:
-
a) operating a blower motor to generate airflow that carries particulate from a work area to a canister housing of the canister vacuum arrangement, the particulate including larger-sized particulate and finer-sized particulate;
b) separating the larger-sized particulate from the finer-sized particulate by circulating the airflow within a separation chamber of the canister housing;
c) collecting the larger-sized particulate within a particulate collection region of the canister housing, the particulate collection region being located below the separation chamber;
d) collecting the finer-sized particulate in a filter positioned in a filter chamber of the canister housing, the filter chamber being located above the separation chamber, the filter chamber including a dirty air input side and a clean air output side; and
e) exhausting clean filtered air from the clean air output side of the filter chamber through an annular opening formed between the filter chamber of the canister housing and the separation chamber.
