用于清洁污点，可快速切换多种清洁液。
专利摘要
一种抽取式清洁装置，其容纳多种清洁溶液，可通过操纵联接到抽取装置的控制件来分配。多个清洁溶液供应储液器联接到清洁装置并与分配头流体连通。通过使用控制件，操作者可为特定应用选择特定清洁溶液。操纵控制件允许在不同应用的清洁溶液之间几乎即时转换。清洁装置的一些实施例具有壳体，壳体的端部在清洁操作期间接合地面。壳体至少部分地包含若干清洁溶液供应储液器、冲洗流体储液器和抽取流体储液器。真空源也可容纳在壳体内。
Original abstractAn extraction cleaning device housing multiple cleaning solutions that can dispensed by manipulation of a control coupled to the extraction device. Multiple cleaning solution supply reservoirs are coupled to the cleaning device and in fluid communication with a dispensing head. Through the use of the control, an operator can select a specific cleaning solution for a specific application. Manipulation of the control allows for nearly instantaneous conversion between cleaning solutions for different applications. Some embodiments of the cleaning device have a housing with an end that engages the ground during cleaning operations. The housing at least partially contains several cleaning solution supply reservoirs, a rinse fluid reservoir, and an extracted fluid reservoir. A vacuum source can also be housed within the housing.
