Stihl SEA 50 cordless wet & dry vacuum cleaner is a compact, portable machine designed for homeowners and semi-professional users who want proper wet and dry cleaning power without being tied to a mains socket.
Running on the STIHL AK battery system, it’s ideal for garages, vehicles, stairs, workshops and confined spaces where flexibility matters. With constant suction throughout the battery charge, dust class L filtration and smart onboard accessory storage, it’s a practical cordless vacuum for everyday clean-up work.
Compact Cordless Wet & Dry Cleaning for Home and Light Trade Use
The STIHL SEA 50 is built for users who want proper wet and dry vacuum capability without the restrictions of a power lead. It’s aimed at homeowners, hobby workshop users and semi-professional trades who need a portable cleaner for everyday jobs rather than a full-scale site extractor.
With its compact body, shoulder strap and cordless flexibility, the SEA 50 is particularly useful for cleaning in places where plug-in vacuums are awkward — stairs, garages, vehicles and confined indoor spaces.
Consistent Suction with STIHL Constant Power
Battery vacuums often feel strong for the first few minutes and then fade. The SEA 50 avoids that with STIHL Constant Power electronics, helping maintain steady suction throughout the battery runtime rather than dropping off as charge reduces.
The brushless EC motor delivers 300 W of performance, making it a capable cordless option for mobile clean-up work.
Wet and Dry Pickup with Dust Class L Capability
This is a true wet and dry vacuum, suitable for general household debris as well as workshop materials. With dust class L certification, it can handle common renovation and trade dusts such as plaster, sand and coarser wood dust.
The washable PET filter element can be reused, keeping maintenance simple and running costs down over time.
Practical Capacity for Everyday Jobs
The SEA 50 offers an 8.5 litre dry container capacity and 5.3 litres for wet pickup. That’s the right scale for vehicle cleaning, small workshop clear-ups and routine household use, without the bulk of a larger industrial unit.
Designed for Portability and Convenience
STIHL has focused heavily on usability. Accessories store directly on the machine, so the hose, tubes and nozzles are always close to hand and ready to use immediately.
The suction hose length of 1.8 m gives good reach for awkward areas, and an optional trolley is available if you want a wheeled setup for larger spaces.
AK Battery System for Home Users
The SEA 50 runs on STIHL’s AK battery platform, making it a sensible choice for homeowners already using AK tools. With the recommended AK 20 battery, runtime is around 27 minutes at full power, which is ample for most mobile cleaning tasks.
A Sensible Cordless Vacuum for Flexible Clean-Up Work
If you need a compact wet and dry vacuum for garages, cars, workshops or indoor spaces where portability matters more than maximum container size, the STIHL SEA 50 is a practical cordless option. It delivers consistent suction, proper filtration, and the sort of smart storage that makes it easy to grab and use without fuss.
