An extraction cleaner may include a base, an upright body pivotally coupled to the base, a supply tank removably coupled to the upright body and a recovery tank removably coupled to the upright body. The base may include a non-removable door and a removable suction nozzle. At least one fluid dispensing nozzle may be provided on the door. The door may be pivotally coupled to the base for providing access to an agitator. The cleaner may include and auto-spray configuration. The cleaner may include a support on the upright portion for the recovery tank. The cleaner may include an additive tank received in a receptacle of the supply tank. The recovery tank may include a float and/or an airflow management configuration. The cleaner may include a cleaning tool and a suction changeover valve and/or a fluid changeover valve. The cleaner may include a mixing valve for supplying fluid to a fluid changeover valve. A cleaning composition including an aqueous based cleaning solution mixed, on demand, with an aqueous based oxidizing solution is also provided.

Extraction cleaner

An agitator including an elongated main body configured to rotate about a pivot axis, one or more soft cleaning features coupled to and extending over a substantial portion of a surface of the elongated main body, the one or more soft cleaning features defining at least one channel, and at least one deformable flap disposed at least partially within the at least one channel and extending from the elongated main body. The deformable flap may extend beyond an outer surface of the soft cleaning features. The channel may have a generally U shape and/or V shape. The channel may be configured to allow the resiliently deformable flap to move front to back as the agitator rotates about the pivot axis.

Nozzle for a surface treatment apparatus and a surface treatment apparatus having the same

Various illustrative handheld surface cleaners and methods of using handheld surface cleaners are provided. In an exemplary implementation, the handheld surface cleaner is configured to use suction to draw debris into the handheld surface cleaner. The suction also causes air to be drawn into the handheld surface cleaner. The handheld surface cleaner is configured to separate the air and the debris on board the handheld surface cleaner to allow the air to exit the handheld surface cleaner and to allow the debris to be collected in the handheld surface cleaner for later disposal.

Handheld surface cleaner

An agitator for a vacuum cleaner includes an agitator body and a resiliently deformable flap. The resiliently deformable flap includes a front face, a rear face, and one or more protrusions extending outwardly from the front face. An agitator for a vacuum cleaner includes an agitator body and a bristle strip and/or a plurality of tufts arranged in one or more rows along the agitator body. The bristle strip and/or a plurality of tufts includes a first bristle group including a plurality of nylon bristles and at least a second bristle group including a plurality of para-aramid bristles.

Agitator for a surface treatment apparatus and a surface treatment apparatus having the same

A cleaning device and methods for cleaning are provided. In one embodiment, the cleaning device includes a head assembly, a body assembly, and a handle assembly. The cleaning device also includes components that enable the cleaning device to operate in dry cleaning modes and wet cleaning modes. Dry cleaning modes can employ a vacuum assembly, including a motor, tubing, and a fluid recovery tank in order to draw in debris and waste into a fluid recovery tank. Wet cleaning modes can further employ a fluid supply tank, a pump, and tubing in order to supply fluid to a brushroll to aid in a cleaning process.

Wet dry appliance

A nozzle having castellations provides high suction pressure while also allowing for large pieces of debris to pass through inlet openings. In more detail, a nozzle for a surface treatment/cleaning apparatus is disclosed herein. The nozzle provides a suction channel through which debris passes into a main body of the surface treatment apparatus. Castellations are provided along a leading edge of the nozzle to allow debris to pass through the leading edge to the suction channel, and into the main body during, for instance, forward and reverse strokes of the surface treatment apparatus. In an embodiment, the castellations further include receptacles/cavities to receive and securely hold wheels therein. The wheels may extend from the nozzle at a predefined angle, also referred to herein as a camber angle, to improve vacuum handling and reduce noise during operation.
