The contractor Series upright has a high-performance, long-life motor for powerful cleaning results. It features a quick-change power cord that eliminates down-time caused by damaged cord replacement. The quick-change furniture guard won't mark, and protects furniture as well as the vacuum. It is easily replaced with just four screws - no need to heat or stretch into place. The impact-resistant Durafan fan motor handles paper clips, screws and staples, eliminating the need for magnets. Rear wheels glide easily and have bearings for long life. The looped handle with fingertip on/off switch adds convenience and reduces damage from excess foot weight. The quick-change bristle strips are inexpensive and easy to replace, eliminating the need for expensive brushrolls.
