BACKGROUNDThe present invention relates to vacuum cleaners.
Vacuum cleaners may include a power head including a fan and a motor for generating a suction airflow. The suction airflow supplied by the vacuum cleaner is often used for collecting debris and depositing the debris in a collector or compartment. These collectors are often removable from the power head to empty the collector
SUMMARYIn one embodiment, the invention provides a modular vacuum system including a first canister with a first capacity configured to store debris, a second canister with a second capacity greater than the first capacity, a first power head and a second power head. The first power head is coupled to either the first canister or the second canister. The first power head is operable at a first voltage to generate a first suction airflow, and the first power head can be coupled to the first canister such that the first canister receives the first suction airflow. The first canister stores debris separated from the first suction airflow. The first power head can be coupled to the second canister such that the second canister receives the first suction airflow. The second canister stores debris separated from the first suction airflow. The second power head can be coupled to either the first canister or the second canister. The second power head is operable at a second voltage, greater than the first voltage, to generate a second suction airflow, and the second power head can be coupled to the first canister such that the first canister receives the second suction airflow. The first canister stores debris separated from the second suction airflow. The second power head can be coupled to the second canister such that the second canister receives the second suction airflow. The second canister stores debris separated from the second suction airflow.
In another embodiment, the invention provides a modular vacuum system including a first canister with a first capacity configured to store debris, a second canister with a second capacity greater than the first capacity, and a power head that can be coupled to either the first canister or the second canister. The power head is operable to generate a suction airflow. The power head can be coupled to the first canister such that the first canister receives the suction airflow and the first canister stores debris separated from the suction airflow. The power head can be coupled to the second canister having a greater capacity than the first canister such that the second canister receives the suction airflow and the second canister stores debris separated from the suction airflow.
Other aspects of the invention will become apparent by consideration of the detailed description and accompanying drawings.
Before any embodiments of the invention are explained in detail, it is to be understood that the invention is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the following drawings. The invention is capable of other embodiments and of being practiced or of being carried out in various ways.
