Generally, interior pavers that have been grouted and sealed just need to be swept, mopped, and spot-cleaned as needed with a gentle, non-acidic multipurpose cleaning solution, such as Enviro Klean All Surface Cleaner or Light Duty Concrete Cleaner. Exterior paver patio hardscaping is even more low-maintenance.
The old cleaning solutions are still the best ones, even with pavers. Use your everyday hand soap or dishwashing soap and add in some water to maintain and clean your paver surfaces.

The pressure washer in combination with a dirt cutter is an excellent option. This removes not only weeds and moss from the surface, but also from indentations.

Paver sealant is a great tool to keep paver driveways, patios, walkways, and pool decks, in mint condition, but it's not always necessary. While it's not a must-have, pavers that aren't sealed typically grow weeds in the cracks, lose color over time, and can even have shifting caused by a lack of joint sand.
Pour the sealer into a paint roller tin and use a long roller brush to apply the sealer onto the paver surface. Make sure you're working in sections that'll keep you from getting trapped in a corner.
