Description

Surface cleaning apparatus for cleaning a floor surface

Technical Field

The present disclosure relates to a surface cleaning apparatus for cleaning a floor surface.

Background

Existing floor cleaners clean a floor with a high flow of cleaning liquid in a manner that enables complete wetting of the floor to be cleaned. The cleaning head transfers dirt and dust from the floor to the cleaning liquid by wetting the hard floor surface, after which the cleaning liquid is removed from the hard floor surface and held in a recovery tank as contaminated cleaning liquid.

A wet surface cleaner generally includes: a supply tank containing a cleaning solution; a recovery tank for recovering contaminants recovered from the cleaned floor; a motor driven vacuum source to create an evacuated flow path from the floor being cleaned to the recovery tank; a rechargeable battery to provide power to the components; a base station for charging and post-cleaning maintenance of the wet surface cleaner.

In order to enhance the cleaning effect, the prior art wet surface cleaners require a cleaning agent to be added to the supply tank during use. However, the ratio of the cleaning agent to the clean water is difficult to control artificially, and the excessive cleaning agent can cause the floor to be wet and slippery; no detergent is added or the amount of the detergent is less, and the cleaning effect is poor.

Moreover, when the cleaning agent is present in the supply tank, the surface to be cleaned needs to be cleaned using the cleaning agent regardless of whether the surface to be cleaned is clean, which undoubtedly wastes the cleaning agent and causes the surface to be cleaned to have cleaning liquid residue thereon.
