Based upon one's own usage capacity wise these little Whirlpool/Kenmore washers will hold lots of small items (socks, baby's things, undergarments, etc..). Linens wise perhaps five or so napkins and or placemats. Two to four pillow slips (depending upon size), but sheets other than crib or twin (one at a time) is about far as one can go on that score.
One to three shirts, pulls, or vests, again depending upon size.
As with all washers with central beaters capacity is limited by how things can be rolled over. Stiff crisp bed linens have same issues in my small Kenmore Jr. washer as doing them in full sized top loader with agitator.
These washers are heavy however, largely due to that whacking big motor.
