when my Eureka Maxima go up in smoke one day , I decide to try a comparably-priced and weighting replacement of a different brand . review suggest this might be the right one . one thing I like be that , unlike nearly all Eureka model , the exhaust air come out the side rather than blow thing around in front of you path . it be very easy to assemble , with one screw secure the upper to the lower portion , then put the accessory in place . it be not quite as easy to push around my thick carpet as my Maxima , which actually pull itself along with its brush roller , but be easy to push on my thin carpet . it appear to pick up about the same amount of dust as my Maxima , perhaps with more trip , as it be not quite as wide . the main dust cup be not nearly as large as the huge one on the Maxima . this be not a problem for I , as I only have a small area to cover . however , this may be a problem if you have a huge area to cover , heavy traffic and vacuum it infrequently . unlike the single large washable hepa filter on the Maxima , which also serve as a baffle , you have a small terminal nonwashable hepa filter , after the air flow go through a washable fluted filter surround by a foam rubber filter . the latter normally catch nearly all the fine dust not deposit in the dust bin above , hence be often the only filter require cleaning . to avoid make a mess in the house and sink , I take the vacuum to the porch or patio at cleaning time , dump the dust in a small plastic bag and submerge the 2 plastic dust bin in a large bucket , lightly brushing they side . often , I do not bother wash the fluted filter . however , often I brush the submerge detachable `` helix '' above the dust bin , which serve as a baffle . repeat with a rinse bucket . Make sure to squeeze all the dust out of the foam filter ; otherwise dust from the inside will migrate upward during dry and form a impenetrable crust . during dry , I squeeze the foam filter hard to make sure the inner part be dry . I wipe up any dust that have fall from the top and side of the inner chamber with a damp paper or cloth and similarly wipe off any still adhering dust on the bin . finally , if necessary , I clean the tiny pre-motor filter below the 2 main pre-motor filter , which catch fall dust after the 2 bin be remove .
