    • A vacuum system includes a filter cleaning mechanism which allows the filter to be cleaned without removal from the vacuum. This mechanism can include a carrying handle which is biased against the lid by a spring. The handle may be released from a vertical position, causing the handle to forcefully strike the lid and dislodge debris from the filter. The vacuum may include a spark arrestor disposed around the filter. The spark arrestor encloses the filter and surrounds the filter sides with a metal screen. The spark arrestor has holes formed in the bottom around the outer perimeter of the filter so that debris which is dislodged from the filter falls through the holes and into the vacuum canister.
    • 真空系统包括过滤器清洁机构,其允许在不从真空中去除的情况下清洁过滤器。 该机构可以包括通过弹簧偏置抵靠盖的携带手柄。 手柄可以从垂直位置释放,导致手柄强制地撞击盖子并从过滤器上移除碎屑。 真空可以包括设置在过滤器周围的火花放电器。 火花放电器包围过滤器,并用金属屏幕围绕过滤器侧面。 火花放电器具有形成在过滤器的外周边的底部的孔,使得从过滤器移出的碎屑落入孔中并进入真空罐。
