The Vacmaster Multi 20 is a corded wet and dry vacuum with a 20-litre tank, a self-cooling 200 air watt bypass motor and a 1740W power take-off socket that lets you run a power tool through the vacuum while you drill or sand. The Amazon listing puts it at £66.99 with a 4.5 out of 5 rating from 2,539 ratings, and it takes first place in this guide.

What separates it from the rest is not the specification so much as the evidence behind it. At £66.99 it costs 55p more than the £66.44 machine elsewhere in this guide, but it carries 2,539 ratings against that machine's 24 — roughly 106 times as many buyers on record. The listing is not flawless: it calls the Vacmaster Multi 20 light and compact, then lists "Portable: No" and indoor-only usage, even though one bullet promotes a blower function for gardens and gutters. Every figure on this page comes from the Amazon listing, not from testing we have carried out.

## Questions people ask

**What does the Vacmaster Multi 20 cost?**

The listing shows £66.99, with a 4.5 out of 5 rating taken from 2,539 ratings.

**How do those ratings break down?**

The breakdown given on the listing runs 72 at five stars, 17 at four, 5 at three, 2 at two and 4 at one.

**Can I use the Vacmaster Multi 20 without a dust bag?**

Yes. The listing says it works bagged or bagless: fit a dust bag to dispose of dirt and fine dust hygienically, or run it without one when vacuuming larger rubble or liquids into the 20-litre tank.

**Can I plug a power tool into it?**

Yes. The Vacmaster Multi 20 has a 1740W power take-off socket, so you plug your tool in, connect the suction hose and the vacuum extracts dust as you sand or drill, operated from the switch on the tool.

**Is it suitable for use outside?**

The listing disagrees with itself. One bullet says the blower function turns it into a garden and gutter tool, and another mentions garages and workshops, while the specifications give indoor/outdoor usage as "Indoor".

**Is the Vacmaster Multi 20 portable?**

The specifications say "Portable: No", while the same listing calls it light and compact at 5.2 kg on four wheels. Those two claims do not match.
