B90 Airless Paint Sprayer for House Painting & DIY Furniture

The GUTUBAO B90 is an electric airless paint sprayer designed to speed up interior and exterior painting projects. Powered by an 850W motor that produces up to 18MPa of pressure, it draws coatings straight from 1-gallon or 5-gallon buckets to coat walls, ceilings, decks, and fences much faster than brushes or rollers.

Versatility comes from the three included reversible tips: a 413 tip for detailed trim and cabinets, a 515 tip for general walls, and a wide 517 tip for expansive fences or siding. If a tip clogs during a job, a quick half-turn clears the blockage so you can keep working without disassembling the unit. An anti-drip nozzle design also helps minimize messy leaks whenever you pause.

Built with an impact-resistant hard plastic shell and an industrial pump core, the unit handles workshop bumps and extended run times. Weighing 6.3kg (under 14 lbs) and plugging directly into standard US 110V household outlets, it requires no separate air compressor or bulky air hoses, making it easy to carry up ladders or between rooms.

While the sprayer handles latex, enamel, primer, and stain directly from the bucket, very thick paints will require adding thinner and testing your pattern on cardboard before starting. The listing also does not include information about hose length or specific cleaning tools.

Verdict: The GUTUBAO B90 is a practical choice for DIYers and homeowners tackling medium to large painting projects on walls, siding, or furniture. It offers solid power and easy bucket-fed operation in a portable, compressor-free package.

Do I need to thin my paint before using this sprayer?
The sprayer works directly with latex, enamel, primer, and stain, but if the paint is too thick, you should add thinner and test the spray pattern on cardboard before coating your project.

What do the three included spray tips do?
The 413 fine tip is designed for detailed trim and cabinets, the 515 tip handles general interior walls and ceilings, and the 517 wide tip provides fast coverage on large surfaces like siding, fences, and decks.

How do you clear a clogged spray tip?
Each reversible tip can be cleared instantly with a half-turn, allowing you to resume spraying without taking the nozzle apart.

Does this unit require an air compressor?
No, it is an electric airless system that plugs directly into a standard US 110V household outlet without needing a compressor or air hose.
