BSTY F3-A

Most floor cleaning is a two-step routine: vacuum first, mop second. BSTY pitches the F3-A as a way to collapse that into one pass. According to the maker, the cordless machine targets three common frustrations: dirty water mixing back into the clean supply, missed spots under furniture and along walls, and the upkeep that wet cleaners demand afterward.

Two tanks, kept apart

The central idea is a dual-tank design. Clean water feeds directly to the brush, while used water and debris are collected in a separate tank, so the maker says each pass uses fresh water rather than recirculating grime. The dirty-water tank also uses what BSTY describes as a wet-dry separation structure, holding liquids and solid debris apart to simplify emptying.

Suction, steam and reach

BSTY rates suction at 20000Pa, and positions it against the 10000–15000Pa it cites as typical for household cordless vacuums, aimed at pet hair, grit in carpet fibers and food debris on kitchen floors. A 180℃ steam function is meant to kill bacteria on the floor surface and help reduce allergens, according to the maker, with adjustable intensity so heat-sensitive surfaces such as wood can be cleaned with lower-temperature steam.

The brush head folds flat to 180 degrees, which BSTY says lets it slip into gaps of 5mm or less above the floor, under sofas and along walls. Floor-specific modes include a dedicated carpet mode that automatically boosts suction and limits water output, a wet cleaning mode for marble and tile, and a dry cleaning mode for wood floors.

Key specifications, per the maker

• Suction: 20000Pa
• Steam: 180℃, adjustable intensity
• Brush head: folds flat to 180°, reaches gaps of 5mm or less
• Quiet mode: power reduced to 25%, operating noise of 50dB or less
• Weight: approx. 3kg
• Runtime: approx. 30 minutes in normal mode, approx. 45 minutes in quiet mode
• 3-in-1 charging station with automatic high-temperature brush drying and self-maintenance
• Handle controls for mode switching; display shows battery level and full dirty-water tank
• Includes 4 HEPA filters, which the maker says capture PM2.5-level fine dust
• Two color options, chosen via a post-campaign backer survey

BSTY says a single charge should cover a typical 3LDK home. After cleaning, the charging station dries and maintains the brush while the battery charges, which the maker says removes the need to detach and dry the brush by hand and helps prevent mold and odors. Color options are described as white or gray, selected by backers through a survey after the Kickstarter campaign.
