Hi,any one have the mytee trex rotary.Mytee have a new trex with a smaller 12 inch head.Love the rotaries,have a rotovac360i,good on residential,not so good on commercial as the motor not big enough.

The problem with the T Rex is that it has a fixed as opposed to the floating head on the RX20. The difference is that a fixed head can't cope with undulations in a carpet and will tend to skip off when it encounters uneven patches.
When I saw the T Rex at the TACCA day last year it seemed to leave the carpet damper, but that might be down to the ETM that was feeding it.

Thanks simon,they have a head for commercial,would that be a floating head?

[Simon Gerrard]

A fixed head is basically a 360 degree flat metal plate on to which is attached the vac slots and jets. A floating head, like the RX20 has five individual arms made of sprung steel to which shoes and skid assemblies are attached. Because the arms are individual they can adjust themselves to undulations far better than a fixed head, so that it maintains positive contact with the carpet at all times.
Both the T. Rex and Rotovac both have fixed heads, so too does HM's RDM

they have made several updates and improvements from the original  ... like the carbon fiber shaft is gone and other bits

Hey John,the new head is not cheap,think its something like 900 dollars,now i could be wrong.

Just watched the video. I really like the look of the sprung suspension system. Not the best idea to clean a plain carpet like that with a rotary extractor. The footprint can be very difficult to get out and can cause problems with the customer. The best way is to show the customer a small patch first. Also, the guy was making wide right to left passes, it is better to make much smaller ones and on plain carpet perhaps think about using the machine in a circular fashion so that the footprint  is far more random.
Also don't like the holed vac shoes, we tried this on the RX with holed Teflon glides and this decreases the agitation and increases the drying time. With a closed system like this, where the shoes are in constant contact with the carpet, holed shoes seriously restrict the systems ability to breath, an open shoe allows more air and with it moisture to be extracted. The RX20 HE has high efficiency shoes with a half open vac slot, not sure of the science of this but it provides drying times of around an hour.
If you've already got the machine, it will take a few jobs to get the technique right, but rotary extractors are brill.
