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

A steam cleaning apparatus may include a wand, a cleaning assembly coupled to the wand, the cleaning assembly including a steam generator, and a cleaning head pivotally coupled to the wand. The cleaning head may include a plurality of cleaning pads, a pad motor having a motor driveshaft, a drivetrain configured to transfer rotational motion of the motor driveshaft to each of the plurality of cleaning pads such that a rotation of the motor driveshaft causes a corresponding rotation in each of the plurality of cleaning pads, and a temperature sensor positioned proximate to the drivetrain, the temperature sensor being configured to measure a temperature of the drivetrain.

Steam cleaning apparatus

A surface cleaning head may include a fluid distributor configured to distribute a cleaning fluid, an agitator configured to absorb at least a portion of the distributed cleaning fluid and to agitate debris on the surface to be cleaned, a fluid stripper configured to remove, from the agitator, at least a portion of the distributed cleaning fluid absorbed by the agitator, a debris container, and a removable cover. The debris container may include a solid debris chamber and a fluid debris chamber. The removable cover may include a fluid catch plate configured to transfer at least a portion of the cleaning fluid removed from the agitator by the fluid stripper to the fluid debris chamber, the fluid catch plate being configured to selectively transition between an in-use position and a cleaning position when the removable cover is removed from the surface cleaning head.

Cleaning apparatus

A surface cleaning head includes a housing having a front side and back side, a brush roll rotatably mounted to the housing within a suction conduit and having at least a portion proximate the opening of the suction conduit, a leading roller mounted to the housing in front of the brush roll, and a drive mechanism operatively coupled to the brush roll and the leading roller for driving the brush roll and the leading roller at same time. The brush roll includes an agitator body and a first bristle/flap arrangement comprising a first deformable flap extending from the agitator body and a first bristle strip and/or row of tufts extending from the agitator body and disposed adjacent to the first deformable flap. The first deformable flap is disposed at an aggressive angle and the first bristle strip and/or row of tufts is arranged at a passive angle.

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

An example of an agitator for a vacuum cleaner may include a body and at least one deformable flap extending from the body. The deformable flap may include at least one taper. The at least one taper causes a cleaning edge of the deformable flap to approach the body.

A mechanical pump includes a motor with an output shaft, a cam coupled to the output shaft for rotating the cam when the motor is energized, and a driver with spaced ledges engaging the cam and driven linearly by the rotating cam. The piston is driven by the driver. A cylinder receives the piston therein and includes an inlet section for drawing fluid into the cylinder and an outlet section for pumping fluid out of the cylinder as the piston reciprocates in the cylinder.

Variable flow rate mechanical pump assembly

Embodiments of the invention disclosed herein include steam appliances and methods which apply steam and a liquid containing a cleaning agent to the floor via separate outlets. In some embodiments, the liquid containing a cleaning agent is applied to an area of the floor that is physically separated from a steam application area. The steam may be applied to the floor through a steam-permeable fabric. The liquid containing a cleaning agent may be heated before being applied to the floor or being mixed with steam.

Steam cleaning appliance

A steam generator to convert liquid into vapor having an inlet to receive liquid, a heating element, and an outlet to discharge vapor. The steam generator may further have a plurality of pathways to facilitate the flow of liquid or vapor through the steam generator. In one embodiment, one or more filter elements disposed in a chamber of the steam generator may help with preventing the buildup of precipitated particulates in the steam generator. In an embodiment, an exit conduit may be configured to further help with preventing particle buildup in the steam generator. In some embodiments, a body may have an inner and outer body and multiple chambers through which liquid or vapor passes as liquid or vapor travels through the steam generator.

Steam generator

A steam frame for a steam appliance has a body, a passageway in the body for passage of a fluid medium, and a member such as an unbalanced rotatable turbine in fluid communication with the passageway, where the member is capable of being engaged by the fluid medium to produce vibrations in the body for enhanced cleaning performance. A steam attachment includes a body, a pad covering at least a portion of the body, and a heating element coupled to the body. The heating element and vibration-producing member may be used separately or together.

Steam cleaning appliance with vibration and heating components

A steam generator includes an inlet configured to receive a liquid (such as water); a heating element for converting the liquid into a vapor (such as steam), the vapor bearing particles such as mineral deposits formed by the converting of the liquid; an outlet in fluid communication with the inlet, the outlet configured to discharge filtered vapor and having a size on the order of larger ones of the particles; and a filter structure adjacent to the outlet to filter the larger particles out of the vapor to produce the filtered vapor for discharge from the outlet. By action of the filter structure, larger particles are prevented from reaching the outlet, reducing clogging and extending the usable lifetime of a small appliance containing the steam generator. The filter structure may include spaced-apart members such as posts or pillars extending perpendicularly in a planar fluid flow passage.

A steam frame for a steam appliance has a body, a passageway in the body for passage of a fluid medium, and a member such as an unbalanced rotatable turbine in fluid communication with the passageway, where the member is capable of being engaged by the fluid medium to produce vibrations in the body for enhanced cleaning performance. A steam attachment includes a body, a pad covering at least a portion of the body, and a heating element coupled to the body. The heating element is configured to increase the temperature of the pad for enhanced cleaning performance. The heating element and vibration-producing member may be used separately or together.

A selectively attachable attachment device for a steam appliance is capable of delivering a mixture of steam and a cleaning additive for cleaning surfaces. The attachment device includes a member that can be coupled to a steam source, and a housing configured to receive the member. The member and the housing include complementary tabs and detent(s) such that an adjustable spacing may be maintained between the steam nozzle and the additive nozzle. The adjustable spacing permits control of the rate at which cleaning additive is added to the steam.
