"Wet & Dry vacuums"
<span style="font-family: arial, helvetica, sans-serif;">About the "tanks have to be emptied, cleaned out and allow to dry before reassembly. Brush must also be removed, washed then allowed to dry as well", I have a Osotek Horizon (which is not that different from the Bissell Crosswave, and states the same in the User's Manual) and I do not bother any of that. </span>
<span style="font-family: arial, helvetica, sans-serif;">I just empty and rinse the dirty water tank when it is full and reinstall it immediately without worrying about drying it; if it isn't full, I just wait until it is. </span>
<span style="font-family: arial, helvetica, sans-serif;">For the clean water tank, I just re-fill it when it is empty, but never rinse or dry it, and if it is not empty, it stays on the machine ready for use. </span>
<span style="font-family: arial, helvetica, sans-serif;">For the brush roll, apart from the (very) occasional self-cleaning, I never remove it and less than ever let it dry: it stays happily wet between uses. </span>
<span style="font-family: arial, helvetica, sans-serif;">Never had any issue, no smell, no mould</span>
