Automatic shut-down when vacuuming liquids once the maximum filling height is reached. Also features an auto take-off enabling the use of a power tool in conjunction with the vacuum. Fitted with two polyester filter cassettes that have a large filter area for constantly high suction capacity.
Very good quality. Powerful and effective. Small criticism is that bits n bobs don't pack neatly away into it (don't know how they'd do that but it'd be handy).
