There is a new Serena at the vac shop I go to-been there now for a few years-nobody wants it-not even me.I have a few Rainbows-interesting to use on occasion-but heavy,awkward,inconvenient to use-emptying and cleaning the bin.Dump the bin for mine outside-remember what the Rainbow salesman sales----"Gets the dirt from out of your house!"Empty the water bin outside and does just that.Waters the plants out there,too!Prefer other machines.also have a Hyla-got that from the Rainbow dealer here-not even close to the Rainbow in quality.The Rainbow is a higher quality unit.
