Threshold Bar 1pc Splicing Slope Bar for Sweeping Robot, 58 cm long climbing pad step with rounded edges enables smooth obstacle crossing for general models. Benefits: Helps sweeping robots cross door thresholds without snagging; rounded edges protect the device and surrounding surfaces; designed for use with a wide range of general model sweepers. Climbing Pad Made of long lasting silica gel material. This step bar offers reliable performance when used with sweeper devices seeking stable threshold solutions. Benefits: Durable construction for extended use; provides stable, predictable crossing of thresholds when paired with compatible sweeping devices. Slope Bar Multi module design allows quick adjustment to fit various widths, providing flexible matching for different doorway gaps while traveling. Benefits: Quickly adapts to different door openings on the move; helps maintain smooth robot movement across changing spacings. Step Bar Full angle inclined surfaces with rounded corners guarantee easy robot ascension without risk of damage to device or flooring surfaces. Benefits: Facilitates safe and easy ascension for robots; minimizes potential damage to devices and floors during transitions. Use scenarios Home with multiple interior thresholds: Use the Threshold Bar and Slope Bar to bridge doorway gaps between living areas, kitchens, and other rooms, enabling consistent cleaning paths. Office or small business environments: Adjust the modular design to fit varying doorway widths and ensure the sweeping robot can traverse entrance thresholds during routine cleanings. Temporary or travel setups: When moving between rooms or temporary workspaces, configure the Slopes and Steps to provide stable, safe crossing for the robot without altering floor protection.
