So many attacks on Rotovac from the same small group for copying the Zipper. The Bonzer is no more a copy of the Zipper than the Mytee T-Rex and the Hoss 700 are copies of the Rotovac rotary jet extraction technology that was invented by the owner of Rotovac, Cliff Monson. Erik did not invent the dual vacuum port, it was patented in 1972 and is now expired. Erik's patent covers his reversible round Teflon glides and Rotovac's are half round non reversible glides that allow for shorter holes and better vacuum flow. The shape of the Bonzer head is different, the handle is different, the spray jets setup is different, no tools needed to adjust wheels and lighter weight When we communicated with Erik's patent attorney he did not indicate that Rotovac is infringing on the Zipper patent. We asked him to please inform us if they found any infringement and we would be willing to discuss a royalty or change our design to not infringe. Rotovac has been in the business of inventing, designing and producing carpet cleaning tools for professionals for over 35 years. It is our main mission to produce the best cleaning tools at the best price for professional carpet cleaners around the world. We commend Erik for producing the Zipper with it's quality features however do not agree that he invented or owns the exclusive rights to be the only producer of dual vacuum port technology. We were getting requests from our customers for the Zipper so we asked to become a distributor for Zipper and we're turned down by Erik. Our engineers then looked into the patent situation and began designing the Bonzer with respect to not infringe on any Zipper patent. We are now getting rave reviews from Bonzer owners like this one we just received this week from a Zipper owner

Chuck,
The reason I haven’t responded to your email until now is that were making money with the Bonzer!! We love it…as usual Rotovac makes extremely good “ user friendly” equipment .
We love how well it cleans and the smooth operation. Absolutely no back fatigue whatsoever. We like the way it folds up to where we use hardly any space in the truck to store it. For as powerful as it is, it’s extremely lightweight. We know this because we’ve owned a Zipper for several months. This truly out performs the Zipper in residential cleaning in our opinion. It is so much easier to navigate around then the Zipper. My guys always want to use it instead of the wand! Thats saying something considering we have the best wands available.
Just a matter of time before we buy another one…we run Aeotechs and dual wanding might be a thing of the past! How about dual Bonzering…LOL
Since u asked our opinion the only thing we’ve had an issue with is the valve. For some reason ours is sticking and starting to go. Have you had this problem with anyone else? Other then the valve issue no problems and very happy with it.
Thanks,
Bruce
