Weight was mostly positive, with several reviewers finding it light and comfortable, though one found overhead handheld use noticeable.

Small-space suitability was a clear strength, with reviewers recommending it for apartments and smaller homes.

Under-furniture pickup was strong thanks to the slim, low-profile head and easy steering.
