An autonomous floor cleaning robot includes a transport drive and control system arranged for autonomous movement of the robot over a floor for performing cleaning operations. The robot chassis carries a first cleaning zone comprising cleaning elements arranged to suction loose particulates up from the cleaning surface and a second cleaning zone comprising cleaning elements arraigned to apply a cleaning fluid onto the surface and to thereafter collect the cleaning fluid up from the surface after it has been used to clean the surface. The robot chassis carries a supply of cleaning fluid and a waste container for storing waste materials collected up from the cleaning surface.

A method for bonding at low or room temperature includes steps of surface cleaning and activation by cleaning or etching. One etching process the method may also include removing by-products of interface polymerization to prevent a reverse polymerization reaction to allow room temperature chemical bonding of materials such as silicon, silicon nitride and SiO2. The surfaces to be bonded are polished to a high degree of smoothness and planarity. VSE may use reactive ion etching or wet etching to slightly etch the surfaces being bonded. The surface roughness and planarity are not degraded and may be enhanced by the VSE process. The etched surfaces may be rinsed in solutions such as ammonium hydroxide or ammonium fluoride to promote the formation of desired bonding species on the surfaces.

A vacuum cleaner comprises adjacent housings, which contain the filtration and suction fan motor assembly of the vacuum cleaner.

Disclosed are compositions and methods for treating and modifying surfaces and for enhancing delivery of active agents to surfaces treated with the compositions, which comprise siloxane polymers functionalized with pendant moieties comprising anionic groups, specifically carboxylic acid groups. When applied to a suitable surface, the present composition comprising the carboxy functionalized siloxane polymers forms a substantially hydrophobic coating on the treated surface. These polymers effectively deposit on surfaces that have cationic sites, which are capable of forming bonds or linkages with the anionic groups of the polymer. The treated surface becomes hydrophobic due to the deposition of the carboxy functionalized siloxane polymer, which then imparts a variety of end use benefits to that surface such as ease of cleaning, stain removal and prevention, whitening, etc. The carboxy functionalized siloxane polymer further acts as a carrier to deposit active agents onto the surface and to improve retention and efficacy of said actives on the treated surface. The present compositions are useful in a variety of applications including oral care, hair and skin care, personal care, cosmetics, and fabric and hard surface cleaning and conditioning. Examples are oral compositions for use in cleaning and whitening of natural teeth and dental prosthesis; for preventing, reducing or removing plaque, calculus and surface deposited stains on teeth; and for providing shine, smoothness and positive feel benefits to teeth, the compositions comprising at least about 0.1% by weight of a dicarboxy functionalized siloxane polymer in a formulation that effectively deposits the polymer to teeth and other oral surfaces.

A dirt container for a surface cleaning apparatus is constructed from an air impermeable material and exterior walls of sufficient rigidity to maintain the shape of the dirt container. The dirt container may be supplied in a disassembled condition and assembled by a consumer prior to use.

A surface cleaning apparatus comprises a floor cleaning unit having a surface cleaning head, an upright section having a handle, a cleaning unit removably mounted to the handle and an air flow conduit forming part of an air flow path from the surface cleaning head to the cleaning unit, wherein the flexible air flow conduit comprises a portable portion removably mounted to the surface cleaning apparatus and a rigid extension wand. Reconfiguring the surface cleaning apparatus components permits the use of the surface cleaning apparatus in various operating modes such as a first upright operating mode wherein the surface cleaning apparatus is operable with the cleaning unit mounted to the handle, and a second operating mode wherein the cleaning unit is carried by a user and is operable when removed from the handle.
