While the dustbin is large, it requires manual emptying, which some users may find less convenient than a bagged system. However, the lack of bags reduces ongoing costs.

3. **Brush Roll Can Be Invasive**

Once the dustbin is filled, the vacuum becomes heavier, which may make maneuvering slightly more difficult, especially on stairs.

7. **No Self-Cleaning Brush Roll on All Models**

Some versions of the 212H11 may not include a self-cleaning brush roll, requiring manual hair removal, which can be time-consuming.

8. **Not Ideal for Large Homes Without Outlets**

Users with large homes or limited outlets may find the cord restrictive, though this is a common issue with corded vacuums.

9. **Plastic Build Quality**

While durable, the vacuum has a **plastic exterior**, which may not feel as premium as metal-bodied models from higher-end brands.
