Problems solved by technology

The disadvantage of these configurations is that when the bag or container becomes full of debris it becomes clogged and its cleaning performance deteriorates over time
[0004] More generally, since the focus is on providing a vacuum cleaner with complex autonomous systems and a fairly basic floor cleaning solution to sweep dirt and dust from floors, rather than providing powerful suction (as in, for example, an upright vacuum cleaner), So cleaning performance is often unsatisfactory

Embodiment Construction

[0019] first reference Figure 1-5 , the vacuum cleaner 10 has a support chassis 12 that is generally circular in shape and is supported on two drive traction wheels 12 and a castor wheel 16 . Chassis 12 is preferably manufactured from high strength molded plastic material such as ABS, but could equally be manufactured from metal such as aluminum or steel. The chassis 12 provides support for components of the vacuum cleaner 10 (described in more detail below).

[0020] The driven wheels 14 are arranged on opposite sides of the chassis 12 and thus share an axis perpendicular to the longitudinal axis of the vacuum cleaner 10 , which, it should be noted, is oriented in the direction of travel of the vacuum cleaner 10 . Each driven wheel 14 is molded from a high strength plastic material and has a softer, ridged band around its circumference to enhance the wheel's grip as the vacuum cleaner 10 traverses slippery ground.

[0021] The driven wheels 14 are mounted independently of ...

Abstract

An autonomous vacuum cleaner (10) comprising a chassis (12), traction means (14) for supporting the vacuum cleaner on a surface, drive means for driving the traction means and a control system configured to control the drive means to guide the vacuum cleaner across a surface to be cleaned. The vacuum cleaner further includes a cleaner head (22) 50 having a dirty air inlet facing the surface to be cleaned and a separating apparatus (51) carried by the chassis and communicating with the cleaner head in order to separate debris from an airflow entering the separating apparatus via the dirty air inlet. The separating apparatus (51) comprises a first upstream cyclone (74) and a plurality of second cyclones (72) arranged in parallel with one another and located downstream of the first cyclone.

Description

technical field [0001] The present invention relates to an autonomous vacuum cleaner, also known in the art as a "robotic" vacuum cleaner. Background technique [0002] Robotic vacuum cleaners are generally considered and represent a relatively recent but rapidly developing field in floor cleaning technology. The main advantage of a robotic vacuum cleaner over a human-operated vacuum cleaner is that it has the equipment to guide itself around the area to be cleaned, which is the entire floor of a dwelling or a single room, and can therefore be cleaned completely or in a very short distance. It operates largely autonomously and does not require human intervention. [0003] EP0803224A, US5787545, WO97 / 41451 and US7636982 describe some known examples of robotic vacuum cleaners. In known robotic vacuum cleaners, the separation means for separating the dirt and dust from the incoming air flow employs bag filters or equivalent container filters. A disadvantage of these arrangem...
