The 37737 is a premium nozzle for both hard floor and carpeted surfaces. The tool is virtually silent when moving across hard floor surfaces due to the oversized wheel located just under the double pivot neck. The neck pivots first at the tool and then at the neck base to insure maximum cleaning performance. The tool is compatible with all canister vacuums, commercial back pack vacuums using 1.25 in. accessories, and all major brands of central vacuum including Beam, Electrolux, Vacumaid, Cyclovac, MD, Vacuflo, Canavac, Nutone, Eureka, and Imperium. To confirm the 37737, consider the nozzle end of your wand or extension tube. If it has a connection without a button and measures approximately 1-1/4 in. on the outside surface, it should be compatible. The 37737 is not compatible with several brands of European vacuums like Miele which require a 1.375 in. neck.
