AI Technical Summary

Technical Problem

Vacuum cleaners face challenges in efficiently collecting debris on multiple surfaces, including hard surfaces and carpets, due to tangling and wrapping of long debris or hair around the brushroll, which affects cleaning performance and maneuverability.

Method used

A hybrid brushroll with non-uniform flap height, featuring bristle features and flaps with alternating peaks and valleys, along with a catch feature aligned with the valleys, to guide debris into collection areas and prevent tangling, while a stripping element engages debris from the bristles during rotation.

Benefits of technology

The hybrid brushroll design enhances debris collection efficiency, reduces tangling, and improves maneuverability, allowing effective cleaning on various surfaces by guiding debris into collection areas and minimizing interference with rotational components.

Abstract

A cleaning apparatus (10) includes a suction source (12), a suction inlet (14) in fluid communication with the suction source (12), a brushroll chamber (18), and a brushroll (20) disposed within the brushroll chamber (18) proximate to the suction inlet (14). The brushroll (20) includes a brush dowel (24), first agitation elements (26) coupled to the brush dowel (24) and extending outwardly therefrom, and second agitation elements (28) coupled to the brush dowel (24) and extending outwardly therefrom. The second agitation elements (28) each include an outer edge (30) with angled edge segments (32) to form peaks (34) and valleys (36) along a length thereof to adjust collected debris materials in the valleys (36). A catch feature (22) is coupled to the brushroll chamber (18) proximate to the brushroll (20). The catch feature (22) includes stripping elements (38) extending toward the brushroll (20) and aligned with the valleys (36) to engage collected debris materials.
