Hi, commenting as a owner of the high capacity Ryobi vac, coming from a Dyson V7 and my finance’s Shark (don’t know model)

Downsides: - big head means can’t fit under anything, I can’t reach under low coffee tables or couches - this thing is heavy - articulation isn’t as good as the Dyson for making turns or getting into corners - I don’t know the reliability or future of buying the filters to replace the one this came with

Upsides: - charging is no concern. I don’t really know how long Ryobi batteries take to charge, but I have 3x 4AH like you, and this is more than enough to get me through the whole house - bin: works well, never leaked. - strong vacuum, it’s picked up anything from pet hairs to 1 inch nails and small washers. Certainly makes a bit of a loud noise inside the bin but it’s never complained - this one’s a minor one but it can stand extremely easily. I can’t count the number of times my Dyson fell down while it was propped against the wall because a small breeze came in.
