The hours shown on a map listing only tell you when the doors are unlocked, not whether a staff member is actually on-site during those hours or the place runs fully unattended after opening. Every laundromat marked attended here has that confirmed from the shop's own website or posted hours, not just guessed from it being open.

Good to know
What does 'attended' mean at a laundromat?
It means a staff member is physically on-site during the shop's open hours, as opposed to a self-service laundromat that's unlocked but unstaffed. Attended shops can often help with broken machines, sell detergent, or handle wash-and-fold service on the spot.
Are attended laundromats safer than unattended ones?
Generally yes, since having staff present tends to deter theft of clothes left mid-cycle and gives you someone to flag down if something feels off. That said, plenty of unattended laundromats are perfectly safe too, especially ones with good lighting and security cameras.
Are laundromats open 24/7?
While many locations operate standard daytime hours, select self-service laundromats offer round-the-clock service. Across Maryland, you can explore 25 local laundromats to find facilities that accommodate 24/7 access.
Does a laundromat take credit cards?
Modern self-service laundromats increasingly accept credit cards, debit cards, and mobile app payments alongside traditional quarters. Throughout Maryland, our catalog features 25 laundromats, allowing you to check equipment details and preferred payment methods.
