| 摘要 |
<p>The invention concerns an appliance whereof the active members for treating floors and other surfaces to be treated are housed in a shell (1) protected by two large protective side wheels (2, 3) with peripheral surfaces (4, 5) capable of elastic deformation, having diameter dimensions such that they largely exceed the shell (1) upper (10), lower (11) and rear surfaces, thereby providing efficient protection for the shell against shocks, while improving running capacity.</p> |
