The new model is worse that the older model.
on January 1, 2016
I have purchased my 3d one after the battery in my 2d died. I love this product, but the newer model it is not getting better, it is getting worse. The known problems were a weak battery with relatively short life and a bad filter: difficult to clean, short life. Both problems were not fixed, but two were added. The charger connection used to be round, easy to plug, the new one is rectangular, much more cumbersome to connect. The on/off switch used to be located on the body and has been moved to the handle and now I accidentally turn the unit off while cleaning.
