Battery: good strong motor, lasts long enough for our purposes Motor: good but gets in the way of bad filter design Filter: that's the MAIN PROBLEM with this vacuum cleaner. And for this reason I cannot recommend this product. It took me a while to figure it out, but the surface area of the filter is pretty small compared to other vacuums. This leads to blockages and loss of suction power after just a few uses. This filter is fan shaped. While the filter in the form of the incoming form has MUCH more surface area. Workaround: If you already own this vacuum, all is not lost. You can use your "regular" large vacuum cleaner to extract some of the dust, which extends the life of the filter to several months (depending on use case).
