How loud is it really?
EyeVac rates it at 75 decibels, which is genuinely loud, in the same range as an ordinary vacuum cleaner, and it is the main drawback. It is the trade-off for the strong, instant suction. Each cycle lasts only 7 seconds, and manual mode stops it starting unexpectedly, but factor the noise in if it will sit somewhere quiet matters.
Does it need batteries, or is it just plugged in?
It is plugged in. The EyeVac Home is a corded, mains-powered unit with a 6-foot cord and a 120-volt US plug, and EyeVac makes a point of it needing no battery chargers or docking stations. Plug it in and it is ready, and hooks on the back keep the spare cord tidy.
Does it have a HEPA filter?
No. EyeVac does not describe the filters as HEPA. It fits three high-efficiency, washable cartridge filters that remove dust, dirt and debris up to quarter-sized and return clean air to the room. That is a real filtration feature, just not the same as the independently tested HEPA standard.
How big is the dustbin, and how often do I need to empty it?
The canister holds 4 litres, which is large for a device this size, and a light comes on when it is full. Even homes with several pets can go days between emptying, and it is simple to do: pull out the canister, remove the lid and the pre-motor filter, tip it out and slide it back. The filters are washable rather than a recurring purchase.
Is this the same as the EyeVac Air?
No. EyeVac sells the EyeVac Air as a separate, upgraded model with a built-in air purifier for improving air quality. The EyeVac Home does not include that function, so if air purification matters to you, look at the EyeVac Air instead.
Is it genuinely useful for someone with back or knee problems?
Yes, and it is one of the best reasons to buy it. A bad back, sore knees or a recent injury make the dustpan the hardest part of sweeping, and here you sweep debris toward the unit instead of bending down to collect the last of it. It also makes a thoughtful gift for an older relative who gets dizzy bending over.
