This is our most popular vacuum cleaner sold! On November 14, 2023 Wirecutter named this model the best canister vacuum cleaner. It is an ultra quiet, lightweight, canister vacuum featuring three on board attachments, a 37 foot cleaning radius, rubber coated wheels to protect floor surfaces and a durable telescopic tube with quick release connections. It has a full bag or clog indicator and a soft foam bumper to protect the vacuum, furniture, and walls from scuffs and scratches. The commercial quality ET-1 power head cleans both carpets and hard wood floors, has excellent pet hair removal and provides manual brush roller shutoff and the extension side of its L shaped contour makes cleaning under counters easy. A parquet brush for cleaning hard wood floors with straight suction is also included. The K3's ergonomically designed handle, which also includes the suction adjustment switch, provides user comfort and effortless control of the power head's 180 degree steering ability and super low 3.5 inch horizontal cleaning profile.
