A modular vacuum system includes a first and second canister of different capacities that are configured to store debris. The modular vacuum system also includes first and second power heads that can be coupled to either the first or second canisters. The first and second power heads operate at different voltages that generate a first and second suction airflow. The first and second canisters store debris separated from the first and second suction airflow. The first and second canisters also store debris separated only from the first suction airflow.

A caddy is provided for mounting a vacuum cleaner for transport and use. The caddy comprises a lower support assembly mounted on a plurality of wheels, a vertical support assembly comprising at least two members vertically extending from the lower support assembly, and an intermediate support mounted on the vertical mounting assembly a vertical distance up from the lower support assembly. The lower support assembly includes centrally-located mounting guides for receiving and holding the vacuum cleaner. The intermediate support comprises a generally circular-shaped member having an opening for facilitating the insertion and removal of the vacuum cleaner from the caddy. A lead is attached to the lower support assembly and may be connected to an intermediate location on a hose of the vacuum cleaner for redistributing a pulling force applied to the hose between the top of the vacuum cleaner and the lower support assembly of the caddy during use.

A handheld window cleaning machine includes a shell assembly in which a water-air separation unit is accommodated; a water tank assembly at a bottom of the shell assembly, a wastewater separation unit in the water tank assembly, an outlet of the wastewater separation unit in communication with an inlet of the water-air separation unit; and a suction nozzle assembly pluggably connected to a front end of the shell assembly, an outlet of the suction nozzle assembly in communication with the wastewater separation unit; an air outlet of the water-air separation unit is open outward, and a wastewater backflow opening at a bottom of the water-air separation unit, and the wastewater backflow opening in communication with an inlet of the wastewater separation unit. The cleaning efficiency of the window cleaning machine is ensured, and wastewater is effectively separated from air

An attachment to a portable vacuum or blower device that allows a user to direct the items collected by the portable vacuum or blower device to a separate container in an easy to carry assembly. The attachment to a portable vacuum or blower device has an adapter, an inlet and outlet assembly, and a lid. The lid detachably couples to a bucket or other container allowing the user to discard the bucket and collected items entirely or store the bucket with the collected items, depending on the items collected. The adapter provides attachments to popular portable vacuum or blower devices.

A lid system for a wet-dry vacuum includes a lid shaped to cover an open end of a container and having a vacuum opening therethrough, and a hatch that engages the lid to cover and seal the vacuum opening when in a closed position and disengages from the lid in an open position to uncover the vacuum opening. A vacuum generator is mounted on the hatch, and a flanged filter is mounted on the lid and extends through the vacuum opening such that the flange supports the filter on the lid. When the hatch is in the closed position, the hatch compresses the flange against the lid to form an airtight seal between with the upper surface of the lid, and the vacuum generator communicates with the interior of the container. When the hatch is in the open position, the filter is insertable into and removable from the vacuum opening.

A modular vacuum system includes a plurality of power heads configured to be removably coupled to a plurality of canisters, each canister having a debris collection chamber of a different capacity, a first power source configured to output a first voltage, and a second power source configured to output the first voltage. A first power head of the plurality of power heads is configured to receive the first power source, and includes a first suction motor rated to operate at a first performance level defined by the first voltage. A second power head of the plurality of power heads is configured to receive the first power source with the second power source, and includes a second suction motor rated to operate at a second performance level greater than the first performance level.

A handheld suction device may provide an ergonomic and convenient device for cleaning a variety of floor surface soils, including liquid soils. In different configurations, the device may provide a variety of different features to efficiently collect and hold liquid removed from the floor surface and/or prevent vacuum motor flooding if the operator over rotates the device when filled with liquid. In some applications, the handheld suction device provides an interchangeable system that allows the operator to switch between different suction attachments designed for picking up liquid soil and solid soil.

A vacuum cleaner includes a canister defining a debris chamber, a lid mounted to a top of the canister, a debris inlet defined by one of the canister and the lid, and a lid latch rotatably connected to the canister. The lid latch is rotatable between a first position, in which the lid latch is disengaged from the lid, and a second position, in which the lid latch engages the lid to secure the lid to the canister. A bottom of the lid latch is spaced from an exterior surface of the canister to define a handle opening that allows a user to insert their fingers into the handle opening and grip the bottom of the lid latch.

A motor cover includes a lattice structure defining a plurality of vent openings that provide ventilation of the motor cover. Each vent opening of the plurality of vent openings is defined by a first cross member, a second cross member, a first side member, and a second side member of the lattice structure. The second cross member is spaced vertically below the first cross member and the first side member is spaced horizontally forward from the second side member. Each of the first and second side members extend from the first cross member to the second cross member. The second cross member extends further outward from a central vertical axis of the motor cover than the first cross member, and the first side member extends further outward from the central longitudinal axis than the second side member.

A vacuum cleaner includes a canister, a vacuum hose, a motor, an impeller, and a one piece lid. The canister defines a debris chamber and has a top. The impeller is connected to the motor and is operable to generate air flow upon operation of the motor. The one piece lid includes a hose retainer and is mounted to the top of the canister. The hose retainer includes at least two retaining tabs spaced from a central portion of the lid to define an insertion opening. The retaining tabs deflect away from a retention position in a first direction to an open position when the vacuum hose is inserted through the insertion opening. The retaining tabs are biased in a second direction towards the retention position such that the retaining tabs exert a positive retention force on the vacuum hose when positioned within the hose retainer.
