36Wh 2in1 Cordless dustbuster® Hand Vacuum with Floor Extension and Smart Tech Sensors

The 2-in-1 BLACK+DECKER lithium-ion cordless vacuum cleaner with smart tech sensor technology, makes light work of floor and surface cleaning around the home. The smart tech Filter Sensor detects when the filter becomes clogged and needs to be cleaned, helping you to maintain cleaning performance. The intelligent Floor Sensor increases suction on deep pile carpets and switches to Eco mode for lighter tasks, to extend the battery runtime. The smart tech Battery Sensor displays the remaining battery charge, so you’re not caught short of power whilst cleaning. The lightweight, removable handheld vacuum with soft brush accessory is ideal for cleaning any surface, from dust and pet hair, to cereal spillages and crumbs.

A Smarter Way Of Cleaning With Intelligent Sensor Technology

Let your vacuum cleaner do the thinking with smart tech sensor technology. The Floor Sensor automatically adjusts the suction power when you move from hard floors to deep carpet. The Filter Sensor lets you know when it’s time to clean the vac and maintain suction power. The Battery Sensor tells you how much battery remains before it’s time to recharge.

See smart tech in action.
