A robot cleaner including a body, a driven wheel, and a side brush coupled to the body. The side brush includes a hub configured to rotate about a pivot axis and a plurality of bristles. Some bristles may form a first angle with the pivot axis and others form a second angle with the pivot axis which is larger than the first angle. Some bristles may have a first bristle length and others have a second bristle length which is larger than the first bristle length. The robot cleaner may include a side brush deflector to deflect debris propelled by the side brush towards the vacuum inlet. The side brush deflector includes a plurality of deflector bristles extending downwardly from a floor facing surface of the robot cleaner towards a floor such that some of the bristles pass through or underneath a portion of the deflector bristles.

A vegetation pruning device includes a pair of pivotably coupled handles and a motor having a rotary output drive for driving an endless flexible cutting chain. A guard is moved relative to the chain by pivoting of the handles relative to each other to grip vegetation between the guard and the chain. The motor is actuated by pressing each of a pair of elongate triggers at any position along the length of the triggers.

In a first aspect, the present invention provides an air inlet cover () comprising a grille () having a plurality of radial elements () radiating from a center of said grille (), each said radial element () comprising a vane () having a leading edge () for positioning further from a fan and a trailing edge () for positioning closer to a fan, the leading edge () of each said vane being offset from the respective trailing edge () thereof by substantially the same angular amount (&#x3b1;) for each said vane (), whereby the vanes are pitched more steeply closer to the center of said grille () than remote from the center of said grille, and a circumferential element () comprising a bell-shaped mouth enclosing said vanes () and having a plurality of apertures () formed in a surface thereof, each respective one of said apertures () having a first edge () parallel to the pitch of a first respective vane closer to the center of said grille and a second edge () parallel to the pitch of a second, adjacent respective vane remote from the center of said grille. In a second aspect, the present invention also provides a power tool comprising a fan and such an air inlet cover (). The power tool may be a garden leaf blower or a dust extraction machine, including a domestic vacuum cleaner.

Air inlet cover

A vacuum cleanerhaving a housinghaving an inletand an outletis disclosed. Actuation of a motorcauses a fan to displace air out of outlet, and the resulting suction upstream of the fan draws dirty air through inletand inwardly through walls of filter element. In order to clean the filter element, the user lifts lidby means of gripping portion, and then removes filter elementand dirt collection chamber. Because the central portion of the dirt collection chamberis raised, dirt trapped on the outer surface of filter elementhas a tendency to fall into trough regionsand avoids falling into outlet. If the motorshould accidentally be actuated when the filter elementis removed, the opening provided by opened lidis nearer to outletthan inlet, as a result of which relatively clean air from the atmosphere passes into recessin preference to dirty air from the inlet, thus minimizing the risk of the motorbeing damaged by dirt.

A vegetation pruning device () includes a pair () of pivotally coupled arms. A motor bracket () with a rotary output drive () provides drive to a cutting element () which is coupled to the rotary output drive (). The cutting element () is arranged for cutting vegetation () presented thereto.

A vegetation pruning device () includes a pair () of pivotably coupled handles and a motor having a rotary output drive () for driving an endless flexible cutting chain (). A guard () is moved relative to the chain () by pivoting the handles () relative to each other to grip vegetation between the guard () and the chain (). The guard is provided with a pair of curved upper surfaces () having teeth (). The rotary output drive () of the motor is arranged generally coaxially with the axis of pivotal movement of the handles ().

A vacuum cleanerhaving a housinghaving an inletand an outletis disclosed. Actuation of a motorcauses a fan to displace air out of outlet, and the resulting suction upstream of the fan draws dirty air through inletand inwardly through walls of filter unit. Air from filter unitpasses along a duct to the motorand fan. The housingis formed from a first housing part defining a recess, and the recess is then closed by means of a closure memberto define the duct between the filter unitand the motor
