A self-propelled, dust-collecting robot includes a main-body part including a dust collection box, and a first battery pack, which has a case, at least one battery cell in the case, a control circuit board having a controller mounted in the case, and a discharge terminal. The main body part includes a first battery pack mount having a connector to which the first battery pack is removably connectable. The first battery pack is configured for use in an electric power tool.

A vacuum cleaner includes a main body and a vacuum head connected to the main body through an air hose. The main body includes a main motor and a main impeller driven by the main motor. The vacuum head includes an auxiliary motor connected to the auxiliary impeller and configured to drive the auxiliary impeller. Both the main impeller and the auxiliary impeller are in the duct of the vacuum cleaner. The vacuum uses two smaller power motors to combine the vacuuming effect of the high power motor. This not only reduces costs, improves overall efficiency, but also reduces noise.

A machine tool device includes at least one open and/or closed-loop control unit and at least one drive unit sensor unit configured to determine at least one drive unit characteristic variable that can be processed at least for the purpose of open and/or closed-loop control of a drive unit of a machine tool and/or for issuing information to an operator of said open and/or closed-loop control unit. The machine tool device further includes at least one environment sensor unit configured to determine at least one environment characteristic variable that can be processed at least for the purpose of open and/or closed-loop control of the drive unit and/or for issuing information to an operator of said open and/or closed-loop control unit.

An envelope (10) for use with a vacuum cleaner, the envelope (10) comprising flexible material arranged to provide a fluid path there-through, and further comprising a coupling arranged to couple the envelope (10) to a structural member for in use maintaining the fluid path open by supporting the envelope (10) against external pressure, wherein the envelope (10) is arranged in use to isolate, from the fluid path, the structural member that supports the envelope (10).

The invention discloses a system for vacuuming waste having a motor module and a waste module. The motor module has an open receiving area, motor, battery, vacuum tube receiving area and handle. Multiple bag hooks are spaced along the open receiving area. Disposable bags, having a drawstring within a channel, are placed within the waste module. The drawstring has a length greater than the bag perimeter to form multiple bag loops that extend through gaps in the channel. An insert maintains the bags in an open position. The bag loops are placed on the bag hooks so that when the motor module is opened, the drawstring pulls the bag closed.

A method of cleaning a floor comprises providing an autonomous surface cleaning apparatus, positioning a plurality of docking stations at different locations on the floor wherein a first docking station has an absence of an evacuation mechanism and actuating the autonomous surface cleaning apparatus whereby the autonomous surface cleaning apparatus travels across the floor to clean at least a portion of the floor and recharges at the first docking station.

An envelope (10) for use with a vacuum cleaner, the envelope (10) comprising flexible material arranged to provide a fluid path there-through, and further comprising a coupling arranged to couple the envelope (10) to a structural member for in use maintaining the fluid path open by supporting the envelope (10) against external pressure, wherein the envelope (10) is arranged in use to isolate, from the fluid path, the structural member that supports the envelope (10).

The invention relates to a compact suction station, the structure of which allows it to be arranged in small compartments, such as the skirting board area of kitchen units, said station being protected by a dismountable outer casing in which, in the front part of the assembly, there is an extractable part corresponding to the container drawer, and in which, in the rear part, there is a suction intake for the dirty air from the pipes and the plurality of inlets, and the clean air extraction outlet, the interior of the station consisting of two compartments that communicate with each other, one of them being used for the insertion of the extractable drawer with the container bag and the other to house the motor, the extraction channel and various electronic components.

A kit comprises a plurality of docking stations and an autonomous surface cleaning apparatus. The plurality of docking stations comprises a first docking station that has an absence of an evacuation mechanism. The autonomous surface cleaning apparatus comprises an air treatment unit comprising a dirt collection region in which dirt is collected and contained in a first closable container, a storage region in which the first closeable container is stored within the autonomous surface cleaning apparatus as the autonomous surface cleaning apparatus continues a cleaning operation and a depositing member which subsequently deposits the first closeable container at a location that is exterior to the first docking station.

A leaf blower vacuum cart for mounting, transporting and utilizing an electric leaf vacuum blower and a standard 121635 paper yard waste bag or similar. The invention is a two tiered cart with casters, a bottom shelf and a top shelf. The top shelf has an opening to accommodate a hopper which goes into a standard 121635 paper yard waste bag or similar. The cart can be used with leaf blower vacuums of various makes. A hose is attached to the leaf blower vacuum allowing for extended reach of leaves. A second hose is connected to the exhaust of the leaf blower vacuum and to the hopper. The invention maximizes filling of standard 121635 paper yard waste bags or similar. Full bags are moved on the cart to the desired location.
