Small wall-mounted shop vacuums save space but usually have limited capacity; no more than 5 gallons. Although their hoses are often extra-long, owners say they clog easily. Still, some users praise them as ideal for garage use, because you can vacuum a car or the whole room while the shop vacuum stays mounted on the wall.
The 5-gallon Shop-Vac Hang Up 952-02-62 comes with an 18-foot hose that is 1.25 inches in diameter, and some owners say it clogs easily. However, this model receives mostly positive reviews and an overall 4.1-star rating from about 100 users at Amazon.com. Users say they use it for cleaning cars or garages, and some use it in a woodworking shop. The main complaint is that it's noisy. It has a three-year warranty.
The 4-gallon Bissell 18P0 Garage Pro (*Est. $185) has a 4.3-star overall rating based on more than 35 reviews on Amazon.com. Reviewers praise the wall-mounted shop vacuum's 34-foot-long crush-proof hose and wet and dry sucking ability. Additionally, many users find the Garage Pro relatively quiet. A handful of Garage Pro owners report LED "tank full" indicator malfunctions and hose clogs. The Bissell 18P0 Garage Pro comes with an assortment of attachments, accessory storage caddy, hose holder and wall bracket, and it carries a two-year warranty.
