Vacuum cleaners

The BPV325W is a canister vacuum cleaner available from Shark. The BPV325W typically costs $99.99.

Consumer Reports recommends that you match the features on a model to the needs you have. Here's our take on some of the specifications and features that are commonly available on canister vacuum cleaner models like the BPV325W.

Bag:

Denotes whether the model has a disposable bag. A growing number of vacuums, particularly upright models, use a container that can be emptied eliminating the bag. However, to capture the fine-dirt particles, these models must use a filter (such as a HEPA filter), which can need regular cleaning, or replacement. Replacement filters tend to be significantly more expensive than bags. While vacuums with bags may also use filters, the bag acts as a prefilter that helps to keep the fine-dirt filter cleaner thus extending its performance between cleaning or replacement. Another caveat: Emptying the dustbin and cleaning a filter can be messy, and handling it may expose you to dust and other allergens.

Brush on/off:

This feature allows you to turn off the brush when using tools or cleaning bare floors, eliminating any hazard should the vacuum tip over while you have the hose extended.

Manual-pile adjust:

Adjusts the height of the machine to a carpet's pile height to allow for easy movement and thorough cleaning. Adjustments are automatic on some models, but we prefer the manual control afforded by some models.
