Those two dusting tools are from way back in the day. The squarish one is from Kenmore. It goes as far back as maybe the 1970s and and the round one is so standard it's hard to guess. The color suggests that it might have come off a Compact but I don't think so becaues of the look of the neck. As far as our history goes, swivel neck dusting tools are new. However, vacuums that used curved wands like Filter Queen, GE and Rainbow were a lttle more convenient for dusting the tops of doors and other high flat aras. Kirby was good for this too. Our Air-Way used a vee-shaped dusting tool throughout manufacture, many, many years and Electrolux devised a combination tool back in the 1950s that still exists
Europe, or should I say Asia, has had strong influence on floor tool design. I'm not very appreciative of the new ideas as they employ the red velcro strip for routing surface litter and not floating brush strips as in past. Electrolux, Air-Way, Filtex and Westinghouse (at one time) developed rug nozzles that did not use brush strips.
I have heard of no animal rights protestors input but the interestng aspect here is that mainly animal hair was used for the the brushes in all these tools. I pretty sure horses are glad fo the doing away with of "glue factories" but I am curioous to learn how and why the transition was made. For all the bacon that turns up on our table, there an awful lot of scrub brushes with plastic bristles around I still much prefer vacuum attachments that employ brushes made from animal hair
Venson
Yes, Venson, the brush on the right is from a Compact/Tristar; I've had it since 1985 (bought new) & its the best til I got the one on the left; which doesn't tend to suck delicate surfaces (drapes)
