The eufy RoboVac 11S is an automated vacuum cleaner designed for indoor use on hard floors and low-pile carpets. Before first use, ensure the main power switch on the bottom is turned on, install the side brushes, and fully charge the device. The vacuum can be controlled via the included remote control to select cleaning modes, set schedules, and adjust suction power.

RoboVac Anatomy
The device features an auto cleaning start/stop button, bumper, and infrared sensor on the top. The bottom includes charging contact pins, drop sensors, wheels, a rolling brush, and the main power switch. The dust collector is located at the rear and contains the filter.

Preparation and Setup

- Clear the floor: Remove power cords, small objects, and fragile items. Fold tasseled edges of area rugs.
- Side Brushes: Install the side brushes before the first use.
- Power Switch: Ensure the main power switch on the bottom is in the ON position.
- Charging Base: Place the base on a level surface against a wall. Keep a clearance of 3 ft/1 m on the left and right sides, and 6 ft/2 m in front.
Charging
RoboVac returns to the charging base automatically when the battery is low or cleaning is finished. You can also manually return it by pressing the home button on the remote control. Always keep the charging base plugged in for the auto-return feature to work.

Cleaning Modes
- Auto Cleaning: Optimizes the cleaning path automatically. This is the default mode.
- Spot Cleaning: Cleans a specific area in a spiral pattern for 2 minutes.
- Edge Cleaning: Follows walls to clean edges for 20 minutes.
- Quick Cleaning: Cleans for 30 minutes to save power.
- Manual Cleaning: Use the directional buttons on the remote to control the vacuum manually.
BoostIQ Feature: Automatically increases suction power on thicker carpets. This can be adjusted or disabled in Auto or Quick cleaning modes.
Cleaning and Maintenance
Regular maintenance ensures optimal performance:


- Dust Collector & Filter: Empty after each use. Rinse the filter with water once a week (twice if you have pets). Air-dry for 24 hours before re-installing. Do not use detergent or hot water.
- Rolling Brush: Clean once a week. Remove hair and debris.
- Side Brushes: Clean once a month. Replace every 3-6 months.
- Sensors & Charging Pins: Dust off once a month with a dry cloth.

Troubleshooting
If the RoboVac encounters an issue, it will emit beeps and the red indicator will flash or stay solid. Common solutions include:
- Cannot activate: Check power switch, charge battery, or replace remote batteries.
- Weak suction: Check for obstructions in the inlet, empty the dust collector, or dry the filter.
- Cannot return to base: Clear obstacles around the base and clean charging pins.
