The present disclosure relates to a lawn sweeper designed to collect debris, such as grass clippings and leaves, from a surface such as a lawn, and more particularly to a lawn sweeper with an adjustable brush assembly and characteristics associated with improved storage of such a device. A user may adjust the brush assembly with respect to the housing without needing to move the wheels. The hopper assembly may include a panel movable to be placed in at least two orientations, thereby allowing a user to change the volume within which the hopper assembly may collect debris. Methods are also disclosed for adjusting the brush assembly and for storing a lawn sweeper unit.

The present invention provides for noise reduction during operation of a portable blower by reducing the noise or acoustic energy escaping from the housing outlet and blower tube. The noise reduction is achieved by placing sound absorbing material in the blower tube. The sound absorbing material may include flared upstream and downstream ends to reduce turbulence. The sound absorbing material may be held within the blower tube by an insert frame such that substantial portions of the sound absorbing material are exposed to air passing through the blower tube. Also disclosed is a sound absorbing insert that can be placed within an existing blower tube to retrofit portable blowers with noise reduction technology.

A blower nozzle (30) and a vacuum nozzle (40) extending in parallel with each other are connected to a main body (10) housing therein a fan (19) and a motor (20). The main body (10) is provided with a dust bag (50). In a vacuum mode, air is directly sucked from the vacuum nozzle and is introduced into the dust bag by the rotation of the fan. In a blower mode, the air similarly sucked from the vacuum nozzle is directed toward the blower nozzle.

An improved convertible electric blower/vac. The blower/vac includes an improved air inlet cover with an adjustable choke member. The air inlet cover also includes a pressure ring for increasing the efficiency of the blower/vac impeller when the unit is operated in the blower mode. The blower/vac also includes a blower tube and a vacuum bag collar, each with resilient tabs that engage receptacles on the blower/vac to retain the blower tube and vacuum bag collar on the unit. The housing outlet of the blower/vac includes guides that interact with longitudinal ribs on the blower tube and the vacuum bag collar to reduce unwanted rotational deflection of the blower tube and vacuum bag collar when either is engaged on the housing outlet. The blower/vac includes an improved vacuum tube for use of the blower/vac in the vacuum mode.

A water removal apparatus is provided which enables the user to remove water from a wet surface, such as a back yard lawn or sports field. The apparatus includes a frame structure, a press member, and a water removal system. The press member is rotatably mounted to the frame structure. The press member has openings through which water passes. The water is temporarily collected within the press member as the press member is rolled across the wet surface. The water removal system removes the water from the press cylinder and places it in a storage member. The water may then be transported to a different area, and the storage member drained.

An adjustable nozzle for use with a chipper-shredder vacuum for vacuuming debris from an outdoor surface is disclosed. The nozzle has an inlet for directing debris into the nozzle. The inlet has a first side, a middle section, a second side, and a non-inlet area. The first side has a first nozzle inlet, the middle section has a middle nozzle inlet, the second side has a second nozzle inlet. The cross-sectional areas of the first and second nozzle inlets are greater than the cross-sectional area of the middle nozzle inlet to equalize vacuum force throughout the nozzle. The nozzle further includes a nozzle extension that extends below the nozzle and an adjustment apparatus for adjusting the height of the nozzle extension from the ground to conform the chipper-shredder vacuum to the terrain. The nozzle extension may be raised for bumpy or thick terrain or lowered for a flat terrain.
