Turbo HVR200T-2

I agree with the Henry recommendation, they're very durable vacuums with strong suction, but they are surprisingly quiet. Henry 160 is the smallest canister good for homes. I think you should check out the Henry 200 and Henry 240, their bag compartment holds more and the cords are longer. I think your clients will really like his face and you can draw/add some body builder arms on his tub. Henry fits standard 1.25 inch tools so adding a good Wessel Werk hard floor brush is easy. Backpack vacuums are good for covering large areas that are not cramped or confined. I do not like backpacks if you have to bend and move stuff a lot or stop vacuuming frequently.

I like Henry but Henry lacks suction speed control. For a plush delicate rug the gentlest cleaning is done with a combo brush, brisles retracted, and you can turn down the suction to the appropriate level. The Miele C1 Pure Suction and Sebo K2 Kombi are 2 canister vacuums that you should look at. Both have tools to clean baseboards and much more. The Miele C1 is a little lighter and quieter. The Sebo K2 is a little more durable and it has a longer cord.

I haven't tried the new Bissell SpotClean C5, but I know the Bissell SpotClean HydroSteam is quieter than the older SpotClean Pro series. So I think it's reasonable that the Bissell SpotClean C5 is quieter than the old SpotClean Pet/ProHeat series. I have a Henry vacuum and they are very quiet. It's larger than the Bissell spot cleaners but the Numatic Geroge can do carpet cleaning and regular dry vacuuming and it should be a quieter machine. You could vacuum and then spot clean with the same machine with a George.

I agree the Hoover Portapower is not a good all around vacuum. It has a short stretch hose that you need to pull against and then hold the canister with your other hand or wear the shoulder strap. The Portapower also has antiquated bags, either a fabric dump out bag or a single layer paper bags, the paper bag has poor filtration and the fabric bag is messy to dump out. I also think the Portapower's tools always feel loose. For hard floors and upholstery I recommend a small canister vacuum with wheels so it sits on the ground and you just move the hose back and forth. I recommend checking out the Simplicity Jill $179 and Powr-Flite Newton with Turbo Nozzle $175. Both canister vacuums use hepa bags for easy maintenance and great filtration. The Simplicity Jill is very conventional and easy to like. It's a small canister with a metal extension wand and an automatic cord rewinder. Jill comes with 3 simple tools and a combo floor brush. One downside is the Jill only has a 18.5 ft cord. The Powr-Flite Newton is a copy-cat of the very good Henry vacuum at a fraction of the price. The Newton is a commercial vacuum so it does not have an automatic cord rewinder, instead it has a much longer 35 ft. high visibility cord. The hepa bags are larger. The Turbo version comes with a combo floor brush and a turbo brush for rugs or light carpeting. One downside is the Newton comes with 2 cheap tools instead of 3. Both the Jill and Newton fit standard 1.25 inch tools so adding more tools is easy. Both the Jill and Newton are bigger than the Portapower but you can store them in pieces. I think both vacuums are much easier to use and live with. A cool thing about the Portapower is they have been around for decades and if you really want to try one you can buy a vintage used one for much less than a new one.

All of the cheaper cordless vacuums have more battery and motor problems within a year. No matter the price or brand I recommend getting a cordless vacuum with replaceable batteries and replacement parts available. It looks like the Xiaomi G20 does not have a replaceable battery so I would avoid that. If you live in the U.K. I would take advantage of the amazing prices you have on Henrys. The Henry Quick Pet is on sale for £219 and a regular corded Henry is £129. Thoughts?
