Video on Amazon.com I'm a enthusiastic ...... more on that in my video :-) 12/08/2014: I the device now exactly 8 months in use and am still thrilled. Even larger particles, such as smaller leaves, the sucker swallows without problems. 10.16.2014 10 months of intensive use, and the battery performance is still like the first day. Tip: I always pull the plug of the charging station so that the battery can not be claimed permanently. Only when the cleaner arrived at one (of three) points charging stand, I invite again and then pull the plug again. The unit does not discharge (like others) during the non-use. Tip: I'm going with a dust broom (Sweeper or so - those things where you down a duster anbrigt) on smooth floors and have the nipple in the other hand. Every few feet I suck then the crumbs etc., which were not taken up by the duster and the tuft of hair (have a strong hair dog) from the cloth. This saves towels and my opinion is a very effective type of cleaning, since you so no dust / hair back and herwischt ;-) For some time I suck even our stairs with stair mats (26) with the device and need so only occasionally with the "big heavy machine" ran. VERY strong buy recommendation !!!!! The replacement filters (and a little video of me) can be found here: AEG AEF 144 replacement filter for Rapido (AG5106 up, AG6106, AG6108, AG6114, AG6118, Ergorapido AG3002, AG3013, 2 pieces) In my subjective assessment: Heavy Duty = exchange for 2 years / Medium Duty = after 3 years. I recommend from the filter and knock out strongly to outside in the garbage can, then it lasts longer.
